The Boostaroo amplifier arrived this afternoon. I set it up, put in David Sanborn's "Hideaway" (which I could barely hear before) and it is LOUD and clear; I am laughing and almost crying. Put in audio book disc I could not understand before and now I CAN! Just wanted you to know!
I had read great things about the Boostaroo and was so excited to get mine! Sadly, it doesn't seem to work...when I plug it in, I actually LOSE volume...it's been worthless for me...such a waste of money. :(
I just purchased the R234. I love it. The quality is really good and it's crisp and loud. Thank you.
I stumbled upon this site almost 8 months ago. I decided to try the monthly drawing and thought, "what have I got to lose?" A few weeks later, I won! I was very excited; I got my amplifier just a few days after. I tried the amp and I was simply amazed at how loud it could get! It may sound rather... rehearsed but, honestly, I would recommend this to a lot of my friends and family. Trust me, you will like it.
I love your product. I have had it for nearly a year and go nowhere without it. I can watch TV in hotels, listen to a mp3 player, and hear my computer. This is the best invention.
This product is truly amazing! Their customer service is second to none. I had a delivery problem, they sorted it out straight away and I received my Boostaroo in only 6 days!
I received one of your company's boosters and was blown away. Thanks for supporting America's Soldiers. I was able to listen to my headset on a C17 Aircraft and hear the music. It's a great device.
So impressed was I by the Boostaroo, I bought a second one soon after my first just in case my first one broke; it didn't. Before I forget I should review the Boostaroos ability to amplify the audio played through it. For that I give it top marks, actually improving the sound quality of music while increasing its volume. Some things in life are just brilliant, take a bow Boostaroo!
I have a profound hearing loss and finding a MP3 player that is loud enough for me to hear was a hit or miss. I can't tell you how many MP3 players I have bought and had to return because I could not hear the music on them. Even the cool MP3 players like the ZUNE, and IPODS. I bought the Boostaroo thinking that it was going to amplify the sound enough for me to hear. I was thinking that I would have to return it, but I was wrong. THIS ROCKS!!! Trust me, it is worth the money. It is nothing compared to what I have sent in the past! So, take it from the deaf guy. If I can hear with it, then so will people looking for that extra boost of volume to hear the music over machines at work or just loud surroundings. You will not be disappointed with this amplifier! This thing worth its weight in gold!!!
GREAT PRODUCT...I USED MY BOOSTAROO THIS PAST WEEKEND TO CONNECT MY DELL LAPTOP TO A 400 WATT HOME STEREO SYSTEM. THERE WAS A NOTICEABLE DIFFERENCE IN THE VOLUME AND SOUND QUALITY...I'LL RECOMEND TO ALL OF MY FRIENDS...THANKS
This is an AWESOME Product! I have used the Headphone Amplifiers for 2 years now and they work great! My music is much more clear, full and real sounding now. Plus, the bass is excellent and the high treble is superb. I use them with Koss headphones in the Gym and I couldn't be more pleased and happier with this great invention. Plus, the battery has literally lasted me over a year in both amplifiers. I just make sure to unplug the Input Cord when I am not using it, so that turns OFF the Boostaroo. Thank you for a GREAT PRODUCT!
My Boostaroo is fantastic! I use it at least twice daily in my car, boosting my MP3 player through my car stereo.
Just to let you know it arrived yesterday and I'm very pleased with its performance.
I just got a R234 for use on my motorcycle. I use it for my satellite and mp3 in conjunction with the bike radio input. WOW...FANTASTIC.
I just have to tell you, after I adjusted all of the connections and put my new headsets on with the Boostaroo Revolution, I started listening to Luis Miguel and he may as well have been sitting right next to me with a full orchestra! Your products are FABULOUS and I have never been so pleased with any purchase in the way that I am thrilled over this one.
It is such a pleasure to experience a customer service level and product offering that your company provides. It has been literally decades since I have had the privilege to buy a product at a very fair and reasonable price, and have it perform at the 10-star level that this does. But on top of all of that, to have a real person at the other end of the line who not only knows their product line and how it works, but also has the congeniality and graciousness that I have found in contacting your firm, makes me believe that there is still hope for the USA and the the good old-fashioned pride in America. So thanks again for the inspiration, the great products, and the kindness that is rarely experienced in this new millenium.
I wasn't expecting much from a gadget but I'm pleasantly surprised! I just needed a little more volume and didn't want to invest in a huge receiver. This is a great solution.
This product is revolutionary! (just like how they've labeled it) Trust me its unbelieveable - I now have to turn my iPod down for fear of popping those eardrums. You will not be disappointed. Its money well spent for music lovers on the go.
Best money ever spent. I purchased a garmin for my car for gps and mp3 purposes, but the volume output from my garmin into my car's aux input was just missing that "extra punch". I'm sure garmin does this in order to save on the battery life if running off batteries.I was even considering about dropping well over 300 dollars for an amp and new speakers but I really didn't want a huge "bumpin system" as I'm getting older and I just don't care about such things anymore and there is really nothing wrong with my stock stereo system when listening to the radio or CD. All I wanted was more volume from my garmin and hopefully with no distortion or static. I ran across this usb connected boostaroo and after reading some reviews I said what the hell and I'll give it a try. I plugged the usb adaptor into my cigarette lighter and powered on the usb connected boostaroo (which you can keep the power button on so it starts up with the car ignition, tucked everything up under the dash, and turned on my stereo system. All I can say is WOW! Where I had to turn up my car stereo to 75% is now @ 40% easy. No distortion, no static. Bass and overall sound was very very impressive. I seriously think the bass "sounded" better also. I even put my garmin on pause, cranked the volume to listen for static... NONE. I'm very impressed. Now I have all my electronics radar detector, garmin, and my boostaroo all powering up with my car's ignition thru a 3-way cigarette lighter splitter... all tucked up behind dash... you don't even see any wires nor the boostaroo. This little headphone amp gave me the extra punch/edge I was looking for with out spending big time bucks on a whole new system. Thanks big time!
My Boostaroo works great, and I always have it with me during my frequent intercontinental flights, on which I need to amplify the volume of my headphones to compensate for the noise of the plane.
Wow, I was having such a busy time here, I didn't let you guys know how great your product was received here. I kept one, and used it mostly on my laptop, which doesn't output a lot of volume anyway. It worked absolutely fantastic! The Boostaroo Revolutions that I passed out to the guys here were used on convoys throughout Iraq, and were amazing! They were able to drown out the noise of the vehicles, which is unbearable at times. Thank You so very much for your great product. There are some happy people here because of your dedication to the soldiers here. Thanks Again Kevin Kinzer Task Force 293rd
I use the revolution as a preamplifier to my amplifier for my motorcycle speakers using an mp3 player for the source. The revolution has at least doubled if not tripled the power coming from my mp3 player to the main system amplifier.
I love this little Amp! Get One!
I received my Boostaroo today. WOW!!! what a tremendous difference, and w/no distortion. What a great product, I will recommend to all of my friends.
ALL I HAVE TO SAY IS, BUY ONE!!!
We used our Boostaroo on our recent trip which included 4 different 15 hour drive days. It worked flawlessly and I heard no complaints from the kids about not being able to hear the movies. Thanks!
I bought the Boostaroo Revolution for my Archos. The Archos has absolutely horrible volume, I could barely hear it. When I hooked up the Revolution it was like a completely different player, it sounds amazing now.
Love ur tunes when unchained to your desktop? Gott'a getcha one of these. They make a dramatic improvement. Easily slips in my pocket too. Miss out if you want to. Im Rockin'.
I just purchased a quality mp3 player and top of the line in-ear headphones a few days ago. I was happy with the audio quality but the volume was very disappointing. I searched and found out that a headphone amp was made a mad dash for a local retailer who carried the Boostaroo. WOW!!! Now I got some punch in my tunes. Great product!
I JUST RECEIVED MY BOOSTAROO MINI-AMPLIFIER. IT WORKS JUST AS ADVERTISED. I USE IT IN CONJUNCTION WITH A BLUETOOTH ADAPTER (LOGITECH) AND BLUETOOTH HEADPHONES (MOTOROLA). I RIDE A MOTORCYCLE AND HAVE BEEN UNABLE TO HEAR OVER THE LOUD MUFFLERS WITH STANDARD VOLUME. WITH YOUR AMPLIFIER THE SIGNAL IS CLEAR AND STRONG.
I hope you enjoy the Boostaroo as much as I have! This is my third purchase from this company, and I cannot tell you how much I love these things. They turn your Mp3 player into a powerhouse of sound that can be heard by people standing next to you even with your cheapest headphones on!
I was pleasantly surprised, by the increase in sound! My mp3 player is now, more than loud enough, with NO hissing or distortion. I just wanted to say thanks for all your help, and I can say that I'm a happy customer!
Wow, received my Revolution in less than 1 week. AMAZING sound! What a GREAT product. Now I can hear music like it was meant to be heard through my iPod! I will recommend this product to everyone. Thankyou, Thankyou Thankyou!
I am 65 years old and because of genetic nerve deafness which showed up over 20 years ago and has now left me with 8% hearing in one ear, I was desperate when I ordered your Revolution: I hadn't heard music harmony in years and all of a sudden I could. I have very expensive digital hearing aids that barely let me get by. And I sit here and look at your product as bringing the horrendous cost of less effective digital aids to the many elderly and poor of this nation who often are left with nothing. Yours is the ONLY product that has let me rejoin the human race! Many thanks.
Just wanted to say thank you for the great customer service. My son and I both use our Boostaroo's with MP3 players and the Aux input on the car stereo. Works fantastic!
Just a note to say we love the amplifier!(and 1/6 the price of TV EARS) The whole purchase experience was great! We will do business again.
I discovered Boostaroo and it was like magic - music was a joy again. I am inspired by the improved quality of sound that reaches my ears. Bless the Boostaroo for making performing a pleasure again.
Just received my Revolution. It's absolutely what I was looking for - anyone who is frustrated by the sound caps on European bought iPods should get one! Great customer service, too! Will be recommending to anyone who will listen!
I bought the Boostaroo and I didn't believe that it could do what it said it would. But now I'm convinced, since I hooked it up to my new Bose Portable Sound System and my cell phone. It is fantastic, and sounds incredible.
I just wanted to let you know how happy I am with my Boostaroo. I bought a smartphone that is advertised as a "media" phone and it is crazy how low the volume is on it - with every setting on high. Well I got the original Boostaroo and now I keep my device volume at around 70% - instead of 100% - and I am astounded at the volume level and sound quality. It's just simply awesome. As soon as I upgrade my earphones I will definitely be upgrading my Boostaroo to the Revolution model. Thanks for a great product.
Just got that Boostaroo unit with ac plug-in and it got my PC volume back. Wonderful product, worth every penny I spent.
I've had a couple of these units over the past several years (I think they get swiped when folks see it!) Now I need another! At any rate- very handy, blast the music over the road noise/jetnoise/screamin'-baby noise... whatever. Super product!
Just got my Revolution® Series USB Powered Audio Amplifier and Splitter . OUTSTANDING! Works as stated. 2 day shipping :-)
Maverick and Charlie Girl (my cats) are running for cover.
W O W! I just received my Boostaroo Revolution, no kidding, that thing is GREAT! I am very pleased with this purchase. Thanks guys for the great product! My mp3s sound so much cooler now.
I just received my Boostaroo Revolution today. It is nothing short of spectacular. I just love it. It was easy to splice into my satellite radio on my motorcycle and it is so loud I can hardly turn it up. the best money I've ever spent.
I finally found the headphones that when combined with your revolution, gives tremendous sound quality. Next step would be to create an amplifier that is small and rechargeable and less cumbersome, which looks like part of the headphone itself. Another idea would be to create a mp3 player where the amplifier is built in. WOW!
I bought the Original Boostaroo about six months ago so I could take advantage of the aux. input on my car stereo deck. I couldn't believe how loud it got. But recently I've been feeling the need to go louder, so I bought the Revolution. I could not turn my stereo all the way up since it was so loud. I have aftermarket speakers also, so the sound quality was amazing, a huge difference between the original and the revolution.
I transcribe medical reports. This is the first time in my life that I have not had to have the computer volume control all the way up plus the speaker volume up half way. Now, I have the PC volume only 1/4 the way up! THANK YOU FOR A PRODUCT THAT WORKS.
Just a word of thanks to all of you at Boostaroo. I purchased my first one ages ago to improve the volume output of my iPod. Only recently did the male connector develop a short - a result of my not so delicate handling and the wear and tear of several years of constant traveling. I'm elated and amazed it lasted as long as it did. At any rate, I just ordered a new Revolution and literally can't wait for it to get here. I remain one of your humble fans.
Wow you guys are fantastic kudos for customer service. Oh yeah the amp is making my iPod sound soooooooooooo much better. Thank you! Happy Boostaroo freak Will Cage
Just wanted to let you know that I received my Boostaroo several days ago, tonight was the first opportunity to try it out. I have hooked it up with a set of speakers and my digital projector. The sound was terrific, my grandson now wants to have Mondays as movie night at our house. You have a great product, that has surpassed my expectations. I will be using it soon in a classroom setting where the sound will be a great help.
I just ordered two of these. I have been using one with my MP3 player when I ride my motorcycle for about three years. Finally my son and my wife have figured it out. Thanks!
The quality of this small amp is unbelievable. This completely resolved the low-volume output problem with my computer headphone jack. I am happy as can be! Thank you, thank you, thank you Boostaroo!
Man just wanted to thank you guys! I've been having my little amp for about 5 years now with out any problems at all. Boosts my stereo volume loud enough to enjoy at hwy speeds 70 and above without distortion!
I recently purchased a Boostaroo Revolution to go with a pair of Shure E4c headphones. The Boostaroo makes listening to mp3s on my iPod incredible. The Boostaroo really extends the headphones base response and all my music sounds crisp and clean. This is one of the few products that I've purchased in the past year that actually does everything it advertises. Makes long nights at the library much less stressful.
I found out about this site through a Delphi forum. I read the site and reviews. I didn't know if "doubling" the sound was going to be enough for my Sirius radio I installed on my motorcycle. I happened to see the Boostaroo at and took a chance, thinking if I didn't like it I could return it. I installed it in the parking lot and about blew my ear drums out! I had forgotten to turn the volume down on the radio.I am more than happy with the volume and quality of this product. I should also say my cruiser has modified pipes, a windshield and I use external headphones (not earbuds). I hear as much music as I want or as much traffic as I want. I highly recommend this product.
I love it. THE WORLDS BEST KEPT GADGET SECRET, WITHOUT A DOUBT. Every gadget or audio enthusiast should have one. I bought the basic unit, it to give me louder and clearer audio from my iPod. I often use it on my bicycle. I can fit the amp and my iPod all in my shirt pocket, and hear loud clear audio as I ride, without having to use ear plugs. The battery life is amazing! Mine seems to run for months. If you do not have one, don't hesitate. You really will not be disappointed.
I bought 2 of the original Boostaroo amps a while ago and fell instantly in love with them. I just got my first Revolution, and man what a joy of sonic bliss. Please give your R&D team a nice healthy bonus. I cannot wait to see what you guys (and gals) come up with next. I have made all my friends envious with your portable amps, while they spend twice as much and have to carry more weight to get the same sound quality that my Revolution gives me. The Rev, pushes my Sennheiser HD545 cans to highs I never would have thought. I'll end this and just say, Thank you for creating a awesome product, and as a owner of 3 of your products. I cannot wait till I can own the 4th, 5th,6th, etc products you produce. Keep up the great work.
I'm SPOILED, and you have opened up a whole new world of ear candy for me. I already had an excellent (and expensive) pair of monitor headphones. I didn't think the sound going into them could be improved upon, but the Revolution did exactly that. Bolder, cleaner, more crisp throughout the entire range, with subtleties I never noticed before. I can no longer live without the Boostaroo. Absolutely incredible, so rich, and thank you.
Just wanted to make a comment about the revolution. Was skeptical at first. I drive motorcycle long distances. With ear plugs, road noise, wind noise, engine noise, I just barely hear my satellite radio. Well I can't believe this little (big) device. I mean WOW!!!!! I had my satellite to the highest volume before the device. Then i plugged it in. At the lowest volume, I'm 100% louder. WHAT A DIFFERENCE. Its all I need, thanks, Kurt from CANADA.
I Love my Boostaroo Revolution! I can use it to save the battery on my iPod. I can play the volume much, much lower on the iPod - which means my battery lasts Longer between charges. And that's handy. Second, if I use it with my FM Transmitter in my car, I don't get The dreaded "static drift" because the added power helps it to lock On to my station as I'm driving. And, using it makes my music sound better than ever. Richer, fuller Like I'm right on stage with the band. So, that's a very good thing. And when I go home I can use it with my docking station or mini-computer speakers and get full stereo surrounds sound. Or, go to silent mode and just use it with my headphones. I get Home theater sound out of this little iPod and my Revolution. Thank You so Much Boostaroo!
Recently uncovered a Boostaroo while digging for an HDTV audio system. Hooked it up between the headphone output of the TV and a Cambridge amplified speaker system. All I can say is WOW!!! The fidelity with the HDTV Surround Sound is AMAZING! Keep up the good work.
I recently ordered and received a USB Boostaroo, it works great and I was very happy with the service. Thank You
My Boostaroo with my MP3 player is the only way to fly on my motorcycle.
Ooo do I love this! Your Revolution makes my iPod sounds better than my home stereo. I wasn't that unhappy with the sound of my music, I just needed a way to overcome city noise. I bought the Bose Quiet Comfort headphones and thought that would help. They do, but still not enough volume. I tried the Revolution and I'm amazed. It's not just the volume increase. It changes everything. It makes it seem like I'm right up on the stage and getting down with the band.From now on I'm packing a Revolution.
I love my Boostaroo, not just for the amplification, but also the sound fidelity, which is amazing. It's not just an amplifier, it actually makes everything sound MUCH better.
I've used my Boostaroo (Revolution I believe) for at least 5 or 6 years, perhaps more. I really only use it on airplane flights, but I fly a good bit and along with some excellent Westone earbuds that Boostaroo is gold! Plus I can share with my wife or my kids when they fly with me. Good product. Adds no interference - very clean - and does exactly what they claim, bumps up db nicely.
I purchased the Bostaroo Revolution for Motorcycles as a pre-amp to boost the output from my iPhone and Ipod to my underpowered motorcycle amp and speakers. It worked as promised, and significantly improved the speaker output volume when riding at highway speeds with considerable wind noise.
I did experience significant audio line noise/distortion when first connected, but this was eliminated by use of an inexpensive 3.5mm audio line filter between the Boostaroo and main amp.
Got my first Boosteroo in 1999 to boost the signal of my portable Mini Disc player into quality headphones. It worked great, used for several years and loved it. Since my last divorce, I have not used headphones, yet the Boosteroo is a vital part of my home stereo system. I live on solar and wind power - trying to run most appliances of low power consumption. I use an original Boosteroo to split signals from various music sources into three Class-T 80w mono amps -driving a high end pair of loudspeakers and a 15" subwoofer. The sound is awesome and the Boosteroo adds no noise or distortion.
I just recently traveled out of the country and took my tablet with me to watch movies. I realized that even though the volume was at max, I couldn't hear it hardly at all. I stopped in Dallas to look for an electronics store and stumbled into Brookstone. I asked the worker if they had ever heard of an amplifier or headphones. They said no but have been asked several times the same question. I searched online on my iPhone and the first thing that came up was Boostaroo. It looked cool so I called customer service and asked if they had a store in the Dallas airport. They were sooooo nice and guided me directly to the store and I bought it. After trying it out I had to turn the volume down a little on my tablet. Great product!!! And even better customer service. THANKS BOOSTAROO!!!
There is no better way to hear music on a motorcycle than with an MP3 player coupled to a Boostaroo. The Boostaroo is capable of volume sufficient to overcome the wind noise, clarity is improved and the volume level doesn't have to "scream" to overcome the ambiant racket. It's the best!
I hooked up the Boostaroo to a computer at my wife's office and then connected two sets of speakers so she could listen to Internet radio in two different rooms. Absolutely great sound. Thanks for the great product.
This is fantastic! I've had the original Boostaroo for years, as you couldn't quite hear DVD players in airplanes. It wasn't quite good enough to hear the speakers from my iTouch on my Harley, and so I ordered the Revolution. It is outstanding and works perfectly. Had to actually turn down the volume on the iTouch. Couldn't be more pleased. What an outstanding product.
This is an amazing unit that does just what it claims...amplifies any signal put into it. I recorded lots of voice mp3s and had a hard time hearing some of the files. The Boostaroo gave me just the right amount of boost to make every word intelligible. It works well in a car, plane, etc. I love it!
I Love your product. I was working a flight in first class the other day. The 2 people in 1A & B had no audio for some reason. I was able to hook up my Boostaroo to 2A and Everyone was able to listen to the movie. This made them very happy and I think you might get more sales. Thanks, Mark
I've had the Boostaroo for a couple of years now. It has been beat up, dropped, kicked and abused, but it still gives me excellent performance. I love this thing. It's the only way I can drown out the NYC subway, and enjoy musical bliss to and from work.
Because of insufficient volume while watching movies on my laptop while in flight, I bought the Boostaroo. My wife and I used it for the first time over the weekend and it made all the difference in the world. We'll take no trip without it!
I bought this at a kiosk in the airport because my kids and I were tired of straining to hear our DVDs and other audio devices over the engine roar. This simple device makes a world of difference.
I needed an extra boost for my laptop so my twin-daughters can watch DVD movies while traveling. AND IT WORKS GREAT! Even low frequencies sound much better. Without the Boostaroo, the sound level was way too low, even with 1 headphone. Today I tried 3 headphones and they still outperform a single headphone without the amplifier! Thanks for keeping the promise! A very happy and relaxed dad ;-)
I use the Boostaroo for the kids' TV. My 3 kids each have their own headphones with individual volume control. When we want quiet and the kids are watching cartoons, we just say, "Headphones!" and blessed silence descends. Also works great for the kids watching a DVD on the laptop on a go. Viva Boostaroo!
I recently bought this product and WOW! I wish I found it sooner! Half a year ago I bought a portable DVD player but I could never hear it in the car. Now, I can hear it with good clarity. If you have a product you can't hear well, buy this!!!
Works great. I have purchased four. Three for gifts and one for myself. Great price, arrives fast, and does what it promises to do.
Just a note to say thank you for a fantastic product. I am hearing impaired, and my television earphones were not able to provide sufficient volume. Your product was a lifesaver. I am now able to hear the television audio very clearly.
Well, I have a pair of Sennheisers, and I just couldn't find a portable player who would give enough juice out to make the headphones usable on anything else than an home amplifier. After purchasing this thing, I was suddenly able to enjoy studio quality sound on the go to work.
I have had my Boostaroo for a little over two years and it is unbelievable. I live in Chicago and take the CTA, subway/EL, everyday and the extra noise always cuts through a normal CD players volume. With the Boostaroo I never miss a note and those sitting close enough get to listen as well, I like it LOUD. It is also , usually, very durable as it has been bumped and banged around for most of it's life.
I received my Boostaroo yesterday. Very prompt service thanks. I tried it out with one headset and one set of earbuds. I can't believe the improvement and fullness of sound with the unit. I have been looking for something like this as I fly a lot and the drone of the engines doesn't always harmonize with my music. I think it will also be great hearing the sound on airline movies. Both me and my wife thank Boostaroo for your solution to our problem. A Boostaroo Booster Backer, Ron Gliot.
Received this as a gift about a year and a half ago. What a treat, this is a tremendous value. Works great with mp3, walkman, cd player and laptop, allows multiple people to watch the same movie on a laptop!
I think you underrate the Boostaroo in you FAQ page when it comes to 32 ohm headphones. I've been using it with my Grado SR-60s, which are rated at 32 ohms, and there is a major improvement in both volume and sound quality. There are some great 32 ohm headphones out there from companies, such a my Grados and the Sennheiser 497s, which can be driven quite well by the Boostaroo and will give excellent sound quality from even a very underpowered MP3 player.
My TV doesn't have a headphone connector, it only has stereo RCA audio output. So, I was unable to connect my headphones to it. I learned about the Boostaroo in a electronics store. I bought it and it works very well. Now I'm very happy because, I can listen my TV without disturbing anybody else.
With me being deaf, I was unable to “hear” the sounds coming from my Sennheiser RS 180 headphones..it seemed muffled and faint...but love the wireless headphone freedom as I can move about the house and outside to my patio. Today I received AC Powered Boostaroo Revolution Audio amplifier & Splitter...it WORKED! I can hear sounds comfortably...truly a magic.
I want to thank you all for helping me in every which way you could...and yes if any of my deaf friends want a set up like mine, I surely will refer them to you all.
Many, many thanks,
I purchased the Boostaroo recently and I think this is a must have for any portable music device. I have been using it as a line-out amp to my car stereo input and it works great. This little thing not only boosts your sound levels without loss of quality, but it also increases the battery life of your player. This is reading like a infomercial testimonial I know, but I am truly blown away with the versatility of this gadget. Thanks for a great product and Awesome technical support!
This great little tool allows my wife and me to watch and listen to a DVD on my laptop on long plane trips with ease. It is great!
Thanks for your help getting my Revolution repaired! I have three of them and have gotten some of my family on the also - great product!!
I had only line out in my laptop, which means the sound using earphones was very very low. I have bought a USB sound card and it was just a bit louder. I've recently got this amazing little thing called Boostaroo, and it works great! I recommend it to everyone.
Your product has proved VERY successful in my line of work (military pilot). Because I wear ear plugs while flying, I have been hooking a Boostaroo in series to achieve the desired volume.
I've just received my Boostaroo and couldn't be more pleased. I was considering buying a competitor's headphone amplifier that cost almost four times as much, but the Boostaroo does exactly what I need. I use it with noise-cancelling headphones when I fly. It puts out a clean, full-fidelity signal that lets me hear my music clearly. Great product, great price!
I use your amplifier with an MP3 player which is known for not great battery life and low headphone volume and this will help with both. Volume is better at lower settings.
With the Boostaroo the sound quality is outstanding even at 70 mph. Excellent product.
I bought the Boostaroo after seeing it advertised on another website, when I was going to buy some speakers for my motorcycle helmet. I can only say how happy I am that I did! Without the Boostaroo, audio is virtually non-existant, but with it, I can now hear everything and can even turn down the volume! Excellent product at an excellent price - I have no hesitation at recommending this to anyone and am already doing so to my friends. Plus the service from the company was fantastic.
This will be the second Boostaroo I've owned--I used the first continuously at work. I'm afraid that the first one bit the dust, and I can't do without it! It adds so much to the sound that, without it, I'm lost! I've looked for another one for a while without any luck--I'm so glad I found your site!
Hey all I have just got my hands on one of these great devises. They help me hear my CD Player when I ride the bus. Also, when my friends want to listen to the CD I have they can just plug in!
BIG-volume thanks to all of you at Boostaroo. My little unit came today (already!) and brightened my day. So far, it does everything it's advertised to do.
Tried your Boostaroo. It was last ditch effort at getting CD player heard over built in Honda Goldwing stereo system. It worked. Thank you for music on my wing.
After trying headphones to listen to MP3 files, I came to the conclusion it was just not loud enough. It was very hard to hear in a loud area, so I ordered a Boostaroo and WOW! Now it sounds GREAT! I love this thing. Great product.
I've had my Boostaroo for 5 years and I always bring it with me. bI love the idea of 3 of my friends to listen to music when they don't have a music player.(Giving is better than receiving.)
I do a lot of Motorcycle sport touring and I LOVE this thing!!! I'd been using a rigged auto audio booster to hear MP3 player and this takes its' place perfectly. I can hear my tunes thru my earplugs and over the road noise be it classic rock or German brass bands up to...well, very high speeds!
I must say this is a really great thing for a medical transcriptionist.
The a/c powered boostaroo revolution audio amplifier & sound enhancer works fantastic! I replaced a wireless headphone setup with a wired headphone because the rechargeable batteries kept running down on a long weekend. But when my wired headphones were connected to the back of my DIRECTV box, even with my volume on my headphones turned completely up the sound was still very low. With this amplifier plugged onto the wire and my headphones plugged into it, the volume on my headphones is hardly turned on at all. This unit is so small yet powerful! Thanks, Boostaroo!
I got the revolution paired it with koss titanium pro 1a and it is so clear, even at high volume. I can hear every note. Crisp clear loud sound. Awesome product...I will be buying another revolution for my home.
Package received yesterday. Works very well.
Believe it. I am using the first set of batteries for 90 hours of listening (about an hour a day during my walking time) and there is no sign of fatigue. Amazing. All that on top of the first class quality of the Revolution unit I have. I am very happy with this product.
I am very hard of hearing and originally bought the Boostaroo so that I could hear the audio on my iPad.
Recently I tried it with the headphone jacks on my computer because without it I could not hear the audio. With it I can.
Further I am impressed with how long the AAAA batteries last. I am still on the original batteries and have used it for several hours.
Really pleased with the boostaroo. I use it on my motorcycle to increase the output of my satellite radio or Ipod which I can use with either blue tooth or via custom earplugs. A well built product with long battery life and just the right boost for my electronics products.
I just wanted to say that I ordered your audio booster a few years ago with the same headphones that I ordered today. I do at-home medical transcription, and this device has been very helpful to me. I have hearing problems and after seeing an audiologist for a hearing test, he suggested I get an audio booster. I looked online and found your website. Just wanted to say how thankful I am. I even recommended you to some of my fellow transcriptionists!
Perfect for listening to satellite radio in Military Trucks!
i love it, listening my mp3 in my motorcycle helmet with the Boostaroo is perfect.
I have several Boostaroo Revolution's. A must for the motorcycle Rock-n-Roller.
We own two Boostaroo® Portable Amplifier and Headphone Bundles.We use one bundle to listen to the TV in our bed room. We love how clear the sound is and we replace the batteries very seldom.
we use the second pair of In-line Volume Control Headphones in the bed room so we can both listen to TV with one amplifier.
The second amplifier is used in my car to power a 4 inch speaker I use with my radio scanner.
I have two Boostaroo's and plan on buying a couple more. I have a severe hearing problem and my Boostaroo's allow me to enjoy television, music, the computer and most things that require hearing that my hearing aid alone does not let me do.
I wish that Boostaroo made devices that helped with the telephones as that is still difficult for me and the better phones for hearing problems are too expensive.
Thank you Boostaroo for making life a little better for me.
I love my Boostaroo. I have a motorcycle helmet intercom system. One of the features is the ability to attach an mp3 player. The volume was never loud enough to hear well. Then came Boostaroo. Not I can hear it loud and clear!! Thanks Boostaroo!!
This little gadget goes to show that even though it's a little fellow it packs a giant size punch. I use it in the garden and car and I'm forever being asked what is that, I reply that's my Boostaroo mate !!.
A neat bit of kit, well done.
I ordered the Boostaroo to help improve my volume coming from my computer to my home stereo. I was pleasantly surprised that it added the volume I was looking for. It was very easy to hook-up and all I had to do was adjust my computer volume such that it didn't distort. Don't know how many decibels it increased but all I know is the music coming out of it now is much improved. The only thing I regret is that I didn't know about this sooner. Very satisfied with purchase.
It really does improve the sound quality and boost the volume too! Those AAAA batteries can be more difficult to find in some stores though. I would rather have triple A batteries, they are more common even though they are a little thicker.
Have 3 Boostaroos....like all of them fine. Use the smallest one on my Honda Goldwing Motorcycle to boost XM radio signal and iPod signals back through the speaker system.
Challenges on AAAA models 1. batteries are hard to find. 2. without a switch and light to remind me to shut it off I have left it plugged in and drained the batteries in a few days. Make more stuff...
Hello, I am probably one of your first customers! I still have the Boostaroo. I purchased it for riding my motorcycle and it has never failed. I probably have over 70k miles with it.
Thanks again for a great product I could not do without.
I live in Malaysia, in South-east Asian region. During my leisure time, I like to hook up my laptop to LCD TV to watch various media contents. I use Boostaroo (the model that uses two AA-size batteries) to boost my laptop audio output to my home theatre system (with Y-cable). My encounter with Boostaroo has been a pleasant one ! However, there is always room for improvement for Boostaroo.
I would prefer a model that can be powered with either batteries (AA or AAA, the common sizes) or USB port. I really look forward for this versatility. Personally, I think Boostaroo is of great use for computer users, especially laptop users. I never use it with my earphone, loud sound is bad for ears. Secondly, I would prefer the plastic housing to come with solid color, instead of semi-transparent one. It looks ugly to see the circuit board, the batteries and the sponge around the batteries.
Like I said previously, Boostaroo is great for computer users. Perhaps, the company may consider a tie-up with computer manufacturer like Dell to bundle Boostaroo as accessory. I think many would be happy to have it by looking upon laptop and LCD tv are getting more affordable these days. In fact, many though not all, prefer to play their video and audio contents straight from their computer instead of going through conventional dvd/vcd player. PC provides great flexibility over conventional entertainment appliances.
Ok, that's all for my feedback. Adios !
I am a musician/DJ also working in the radio business. Discovered that the audio output from my headphone jack on my laptop didn't have enough punch to feed the station mixing board, levels to low. Searching the web, found the Boostaroo. What a perfect product. Simple in design, small and compact and gives me the exact boost I need for radio work or for feeding into my DJ gear. I'm also an Electrical Engineer and can really appreciate the engineering that went into the Boostaroo. Fantastic product guys (and gals). MRJay
Installs like nothing easier, works fantastic!
They start working well, but it doesn't last long. The jack input is the culprit. I have two of them, and now they work nicely as doorstops. Shoddy materials and poor workmanship makes these a poor choice. I contacted you people, but was told there was nothing to be done. Now, I will do nothing and avoid these like the plague.
Great product, especially when sharing a media device and sound levels drop and things like aircraft noise takes over. Boostaroo fixes that no problems. Only downside is use of AAAA batteries, which are not always readily available, so make sure you buy a spare when you by any replacements.
Yes indeed I love my Boostaroo. After getting a netbook and wanting to watch a DVD on the player in the car or listen on a train forget it with the regular volume on a net book. Terribly low. I talked to my nephew who has a computer business and he recommended the Boostaroo. Saved my listening times in the car or train or plane. Wonderful wonderful. Thanks to the audio amplifiers at Boostaroo.
I have a 2011 Harley Limited with a Garmin 665 Navigation and Xm radio built in the garmin...The 8mm jack from the Garmin goes into the Boostaroo and then into the Aux. Jack of the radio.The Boostaroo is hidden in behind the radio..Wow the increase in volume is fantastic. Worth every penny..
I found the Boostaroo perfect for my Panasonic flash video camera which had a microphone out but not a headphone out. A complaint on Prosumer Videocams is that they lack a headphone out, but this unit solves that problem. Using the Boostaro with a y stereo female adapter connected to the a/v cables, I was now able to monitor the signal and adjust the auto gain control (AGC), and volume coming in through the microphone. The headphones can also be switched out to a more sound proof type unit to eliminate external sounds for monitoring in a noisier environment. Great value product and highly useful.
I recently purchased a Boostaroo portable headphone amplifier and splitter from Radio Shack to help boost the volume of my mp3 player on my autocom system during a recent 5000 mile trip to Canada on my motorcycle. The unit performed fantastic, and I was amazed at how long the batteries last.
I use my boostaroo revolution to amplify the music from my mp3 player to my monster clarity speaker. Before using the Boostaroo some songs I downloaded had low volume now they come in loud and clear. Great product I love what it does for my music. I'm a portable girl because of my job. Scheduled Bus driver.
Wow! I bought the Boostaroo with the inline volume controls to solve a low output problem with a new Toshiba Thrive. I'm using Sony MDR-22NC ear buds, and even at a low impedance of 15 ohms there was nowhere near enough volume unless you're in a library. I plugged in the Boostaroo and problem way more than solved. I bought the two inline volume controls so my wife and I can enjoy movies in flight at our own comfortable listening level. This is an excellent product at an excellent price. There's enough gain in the Boostaroo that I could turn down the output on the Thrive and still get plenty of volume. I never heard of this product, but having bought and used it I, as a retired broadcast engineer, highly recommend it.
I have just received today my Boostaroo rev. amp. I use it on my sport activity and I am very very impressed and satisfied from the great sound. I am still concerned about the availability of AAAA batteries in Israel at this moment. Bottom line - very happy.
I am hard of hearing and have two Boostaroo's at present and plan on buying more. It really is a great product. I use it for TV, DVD, Laptop and iPod.
Your Boostaroo T613 volume booster was a godsend for me so I can hear better on DVD movies and learning computer skills.
Thanks and keep up improving your products...
Exceptional. FLIPPING EXCEPTIONAL!!
I ordered one to listen to satellite radio on my motorcycle, but once I received it I realized that it did not have a built in volume control to regulate the volume going to my helmet so I had to order that as well (the schematic diagram on this website does not show a volume control). It worked good for about 2 weeks, then one of the connections inside came loose. Rather than re-order a new one, we soldered it back in place. Then the output plug came loose (hey, motorcycles vibrate) and we put epoxy on it. First trip this year it stopped working and we don't know what is wrong but we can hear something rattling inside. Just beware that these are very fragile units. I think I will be looking for something a bit more durable.

Our amplifier units do not come with a built-in volume control. In most cases, the user is able to adjust the volume directly from the audio source. We do offer volume control cables that can be purchased as accessories to all of our amplifiers.
With our R234 amplifier models, the LED cap has an extension built in to funnel the red light. This can sometimes rattle inside the unit.
The customer made no contact with us to deal with the broken amplifier unit. We offer a 90-day return policy and a full 1 year warranty on our amplifiers. We could have easily shipped them a replacement for their unit. We take pride if offering reliable amplifiers. If there is a problem, we will help remedy it.
The Boostaroo Revolution was an easy way to boost the signal from my iPod to my amplified motorcycle speakers and get even more sound from them allowing me to enjoy my music on my road king (loud pipes) even at highway speeds.The only drawback is that the unit is not weatherproof and even though I installed in as dry a location as I could, it crapped out after two years of use. Still the best option out there and I'm ordering another.
I used the Boostaroo t613 on a flight from Dallas TX to Dubiax I used less than 20% of my iPod battery. Used sure 3 amp ear buds and never missed a sound.
Had a Garmin Zumo 550 installed on my motorcycle. The unit is wired so the sound comes through both the external and helmet speakers. The volume was terrible and after some research discovered this is a known problem with the Zumo 550. I purchased the 12 V Boostaroo Revolution and the volume is excellent. I actually had to turn it down one notch.
This item is fabulous with our wired headphones with inline control by Sony. This product solved the problem with upgrading to a LED HDTV that had no headphone jack and one a LCD HDTV that had a headphone jack. With the dual split that we use with our headphones the sound was cut in half on both TV's and NO ONE knew how to work around it with the headphone we use and like. Radio Shack suggested the battery Boostaroo and it worked fine but we prefer not using batteries. A search on the web and we found your company. I have read so many ratings on HDTV and people having exact problem we were having and did not know how to work around it. Plus we bought our two TV's to upgrade into the 21st Century and neither vendor could give us suggestions how to remedy the amplifications of our headphones. We sing your praises!
I do not understand the technology involved, but, boy, can I hear a difference on my Bose headphones.
Hello, just a short note-just purchased your Boosteroo model T613 at my local radio shack and am impressed at the quality of sound I am getting and the saving of battery power I save on my BlackBerry Torch smartphone. These phones use a lot of power already, your product should be sold where BlackBerry and other high end smart phones are sold. The sales person at Radio Shack told me and sold me on your product, but seeing it hanging on a peg on a wall really didn't do your product the justice and respect it rightly deserves.Your product needs a display that people can try and be amazed by. Well thank you for your time and a great product, take care and have a great week. Respectfully, Rick Bertolette Lemoore, CA
I do sound for a southern gospel group. We were using a self-powered mixer, with a 1/4" SPEAKER LEVEL output, but no HEADPHONE output, so, from the mix position at the back of the room I couldn't hear the on-stage monitors, to do a mix for the musicians. I had a LINE LEVEL output on the mixer from the monitor bus, that I was able to plug the headphone amp into, (using 1/4" adapter) and subsequently, was able to hear the monitor mix in my headphones to set-up the proper mix for the musicians onstage. Great sound!
I bought T613 and it made me very happy. The result of this item is outstanding. However' some points for the product designer:1- There must be a hole to attach a lanyard to hang on the neck or put on belt. I use it with my Sansa Clip for sport.2- The red "on/off" light is not well located. Can not be seen easily.3- Inserting the bateries is not as easy as should be.
Wish I knew about this when I first got my iPod. It's a must have if you're using big headphones. The 250 Ohm Koss Pro 4AA I use seemed ok with the iPod. Then I figured out what I was missing in detail and dynamic sound with the Boostaroo Revolution now the iPod isn't struggling to drive them. It's made in the USA too!!! Good Job!
That booster works great. It made a big change in the sound. Thank you
Great piece of kit. I'm and electronics engineer and was about to build one of these
Your R-234 model got here and works great for boosting the helmet speakersso NOW I can hear my MP3 player while riding my motorcycle.
Very Impressive! The first thing I did was hook it up to my iPod Classic with Bose headphones. The sound quality and frequency response was outstanding. Thank you for making such a great product
A very versatile device that I use to increase volume of my MP3 player for input into my home stereo aux input
WoW...WoW!!!!!! Wooooooooooo!!!!!! I Love this $%!#. Hardcore amplifier and you can't get any better than Boostaroo
I use your product to enhance the sound quality and volume for my MP3 player while I ride my motorcycle. Works great!
I am a legal transcriptionist so hearing every single word or utterance is critical to my work. I had a piece of audio that was very faint and I just could not hear it no matter what volume boosting software I ran it through.I had heard of Boostaroo from colleagues at a transcription forum I am a member of (Transcription Essentials) and decided to try it. WOW! It boosted the audio so much I actually had to turn the volume down! It was so easy to use
I have recommended Boostaroo to all my Scopist Support Group members. Your product works well
Hi..I had one that was handy as heck. Lost it last weekend in Cody
My last testimonial said I was going to purchase another Boostaroo for my second Harley 2007 Ultra Classic. Just received it.
I love my new Boostaroo
I want to thank you for the Boostaroo Revolution. I just got it today and I am very happy. Thank you again
boostaroo this item is kicking. Good power
the boostaro product is the best. i use it for my car by plugging in my mp3 player and playing through a radio transmitter. it works great. i would recommend this product to anyone and i have recommended it.
I hook my Boostaroo to my laptop then to my external speakers. The sound is "boosarooed" using less volume and no distortion. I use it for music as well as movies. The quality of sound is fantastic and now fills the room and I can take it anywhere in my laptop case. Simply the best!
We truly LOVE the Boostaroo amplifiers we got to go with our Sony headsets which we use only for air travel. Prior to your product
I do enjoy my Boostaroo tremendously and it works great on recordings that are difficult to hear!! Thanks for a great product!
I LOVE my Boostaroo!! I hook my Ipod to it in my car and WHAT A DIFFERENCE!! Better quality sound thru my speakers and only have to recharge Ipod every 2-3 weeks!!! You GOTTA GET ONE or 2 or 3..............
My order arrived and is EXACTLY what I needed for the application. Wish I had known about this earlier.Thank you.
Received the headphone bundle package this morning and am quite impressed with it. It will be used primarily in the car to listen to music on my GPS. My wife can listen in at a different volume to me. Thanks for quick service.
Great product. Works well to boost satellite radio output on way to the car stereo input jack.
It works GREAT! You have a fine product.
Very pleased with unit. It works better then expected.
GREAT CUSTOMER SERVICE. I recently purchased a Boostaroo Original for usewith my CREATIVE ZEN MP3 player and TORK XPRO helmet speakers. I found theOriginal just didn't provide the volume increase I was expecting. Icontacted the customer service department and explained my situation.Their support guy advised me that it was underpowered for my MP3 player/speakerselection and the Boostaroo Revolution was the appropriate unit for myuse. I was immediately offered the option of a refund for my purchase or anexchange for the Revolution. Really refreshing to find excellent customerservice like this!
Very happy with my amplifier. Just wanted to let you know.
I purchased the 12V Boostaroo in order to install Sirius radio on my Yamaha FJR1300. I purchased a totally cool "Fuze Block" and wired the Boostaroo into the block. AWESOME!! Now I can actually listen to the radio with clarity and volume.
I'm a medical transcriptionist who is losing her hearing because of long-term prednisone therapy. One of my bosses had me order a little Boostaroo amplifier for my PC headphones quite a while ago
Dear Boosteroo:I have had my Boosteroo for a year and have had NO problems. I attach one end to my little ZEN V Plus and the output to my Bose QC-2 headphones. Result? My volume on the ZEN is at 6 when I used to have to blast it at 14 or max it out to use it when walking. It is that good. Well done! I always demo the product by taking it off the boosteroo and then hooking the boosteroo back up. Everyone notices the difference. Great product.
I am profoundly deaf and for a long time just used my Boostaroo with an iTouch. Last night I tried it with my Apple laptop and for the very first time in the five years I have owned it I could hear the audio.
Your products rock! Love 'em!Happy Holidays!
I HAVE A BOOSTAROO AND LOVE IT.
I bought a R234-TV unit and it works great. Thank you for a great product.
I use all 3 types
I'm VERY disappointed in the product that I purchased
I have used 2 Boostaroo products on many long flights with Bose Quiet Comfort 2 headphones. Works perfectly. Thanks for a great product.
Thank goodness for Boostaroo! My dad had trouble distinguishing conversations on television and had virtually stopped watching tv. The amplification of Boostaroo has now allowed him to hear all tv programming at a lower volume and much greater clarity. This is a great product
Your Boostaroo for Ipod with up too 400% increase is the best toy I have had all year...It even beats the Rolex for my birthday!!!It gives back the volume I use to get out of my first Ipod 8 years ago..but does not give enough to distort the music.I finally after 4 years
I purchased you 12 volt amp for my 2010 Harley Softtail Deluxe.I was looking for a small consealable amp to boost the output of my Sirius plug and play receiver. What a product. I can listen with ear plugs with your inline volume control at less then half volume.The biggest asset to your amp is it already has 3.5 in and 3.5 out
I am using the Sony MDR-EX85 earbuds with the T613 battery amp. They are supposedly rated at 16 ohm with 5khz- 23k hz rating. I have it to my PSP and it sounds awesome.
I like your product so much!!! It's awesome! On the internet there are amps which cost 100's of $$$ But Your product is just as good as them!!! High Tec!
Many Thanks to you and the inventor.You did a wonderful job with packing and shipping it
Finally got my boostaroo today! Not that I have been waiting very long. Great product.
I just received my Boostaroo Revolution today and tried it out. It's fantastic! I have a pair of very high end pair of headphones.
I have a severe hearing loss and wear bluetooth enabled hearing aids. I purchased a Voiis stereo music bluetooth adapter for TV audio but the signal was not loud enough. I then purchased your AC Powered Boostaroo Revolution and now the signal is perfect along with very high quality audio. You need alert others with bluetooth adapted hearing aids (with a streamer) about your product. Thank you for this excellent solution to my problem.
We are seniors who travel by air a couple times a year. Our DVD player was impossible to hear (despite the fact that we were using Sony Noise-Cancelling headphones). Alas....our salvation was the Boostaroo Revolution Hi-Fi Amp.
I have Boostaroo for my computer and its wonderful.
I received your AC Boostaroo and am so satisfied! The sound volume -- as I thought it might -- is a major improvement over your battery model.
Thank you for the incredibly fast delivery of my order.I orded it from France on Aug 3th and get it in my mailbox on Aug 6 !!!Boostaroo works perfectly! Exactly want I needed and expectedGood Work !
Thank you for the incredibly fast delivery of my order. The Boostaroo is a great device to boost the volume of my iPod!
JUST AS ADVERTISED!! Got confirmation it was in the mail within hours of order. Arrived Priority Mail in just 2 days.Boostaroo works perfectly! Exactly want I needed and expected. Using for a boost when using earphones on TV at night. Will be ordering another for 2nd TV. Money well spent.
Just got my Boostaroo and it works great.
I just bought your original (3 splitter) Boostaroo from RadioShack and LOVE it! I expected little boost and lots of distortion but instead got the boost I needed and no distortion even with my MP3 player turned all the way up! I'm using the Boostaroo in my car with my Archos 605 MP3 player which I play thru the car (Ford Freestyle) stereo. My problem was that even with the Archos and the car stereo turned all the way up some MP3's just didn't play loud enough to hear when the car windows were open. Now my problem is solved! Thanks for the pleasant surprise of a great product that exceeded my expectations!
Installed an XMP3 portable sat system into a new Ford Mustang. Also installed gateway network bus to enable the system to operate with the OEM stereo. The Boostaroo saved the day. line out power from mobil radio very poor and system install is useless without the Boostaroo. easy to mount and the power supply being a cig lighter is perfect. I will be buying a second unit.
Input signal from my mp3 player to the aux in of my car radio cassette CD player was very week.Then I bought revolution Boostaroo and the problem was solved at once.Now I hear louder sound with the best quality and most important without spending money to batteries.Thank you very much people.
I just love my Boosteroo! Only problem is... I have to hide it from the kids!
LOVE your product on my long motorcycle rides. Many repeat purchases and have passed on tips to many others to buy your good stuff!
Just wanted to thank you for a great product. My 95 year old Dad needed just that little extra "Boostaroo" in order to listen to the TV at a volume that's comfortable for himself.
The Boostaroo Revolution is a great product. I just purchased my second one.
How many times can you say "THANK YOU" to such a great company with super people with such outstanding products?
I ride a Harley Davidson motorcycle with a factory stereo and upgraded speakers. My stereo has sufficient volume, however; when I input music through my Ipod, I lose approximately 25% of my volume. I received a Garmin Zumo 450 for Christmas and it has a built in MP3 player. When playing music through the Garmin, I would lose approximately 50% of the volume. I considered purchasing an amplifier at a cost of around $400 until I learned about the Boostaroo. I figured I had nothing to lose because if it didn't work, I could give it to my daughter. I went riding this past weekend and I am very pleased with the Boostaroo. It brought the volume from the Garmin MP3 player to a level just slightly above the factory stereo. Instead of keeping the volume at 100%, I now keep it at 50%. I would not be able to use my MP3 player without this product. The only drawback is that it operates on batteries. Since this will be a permanent part of my motorcycle stereo system, I need a product that can be wired into my electrical system (inside my faring). I have been informed that one will be available in the future and I am looking to purchasing one when available. I highly recommend this product.
I just had to write to let you know I received my order today and to thank you for such an outstanding little miracle device. I had been put off for awhile by unfavorable user reviews on Amazon, but as I read more of them I began to suspect that some were by people who had no notion of the relationships embodied in Ohm's law.
Your tables of specifications clearly showed that the battery-powered and AC/USB models were identical, except for their power source, and that Boosteroo's effectiveness related directly to the rated impedance of the headset connected to them. However, some people just don't get it. I do, and am very happy with your product: the best little amplifier I've ever tried - hands down.
My endorsement is based on several decades of listening through various audio devices since I have lived with a hearing impairment since age 12 (now 62). So I have had many disappointments along the way. Not with Boostaroo, however. As soon as I received your package, I ran a non-scientific test, finding the weakest audio signal station on our new HDTV and, with my 24-ohm Sony Studio Monitor headphones connected directly, adjusted the TV volume to the level at which I no longer had to lip read to understand what was being said. That level was 90%. I then connected the headset to my new Boostaroo and increased volume from zero to the same hearing acuity level. That reading was 25%! In fact, I couldn't go beyond about 40% without risking damage to my ears or the headset.
In my book, that signal boost is better than outstanding, especially since I could detect no distortion or noise at any frequency. Amazing! I no longer have to drive others out of the room turning up the volume on our external sound system so that I can hear. I can now just use the separate, pre-wired headset directly from the mini-plug circuit on the TV for my level of stereo audio. I can't thank you enough, and my family thanks you too :-)
I finally received my order and I just wanted to thank you for it. The 'Boostaroo Revolution' works just wonderful... it's does everything you claimed it would do.
Due to my advanced age I have to use earphones to enjoy my music and most of all my television programs. This small piece of equipment works miracles and since usually TV Channels deliver audio at different values the volume control is a big plus.
My other hobby is 'Flight Simulation' and my problem it's still the same. Hearing deficiency. So I may consider purchasing one more set.
Thanks again and good luck !
IF YOU OWN A LATE-MODEL LAND ROVER PRODUCT YOU MUST PURCHASE A BOOSTAROO!!
Anyone who has driven any late Rover product with an aux. input should buy this product. The Rover aux. 3.5mm connection offers very poor sound quality at very low levels. Here is a product that more than compensates for both problems. The Boostaroo makes the otherwise very poor aux. connection in a Rover sound like a CD- The best $30 you can spend on a Rover!
