I have a software program that requires me to listen to audio that's synced to the document. When I switched to a new computer, for whatever reason, I couldn't hear the audio through my headphones at all when this software was running. I purchased a Boostaroo, and it is amazing how loud it is. I love it so much, I just bought another one!  

Hi..I had one that was handy as heck. Lost it last weekend in Cody,
Wyoming. For the state tourism office in Wyoming, I have used it to
boost audio at many events whether pushing more sound out of a TV
monitor or a portable Bacini Acoustica at rodeos and other forums where
we meet consumers. For MP3 units the Boostaroo has been a Godsend in
terms of getting the music to a level that is needed no matter the
crowd, or competition. It was also handy on a number of long airline
flights to bring up the volume on DVD movies.

Wonderfully efficient and effective product that gives you the most bang
for the buck of anything I've bought over 20 years in the tourism
marketing business.

Thanks,  

My last testimonial said I was going to purchase another Boostaroo for my second Harley 2007 Ultra Classic. Just received it and, like the first one for the 2010 Deluxe, I am very pleased with the improved sound from the Sirius reciever. It is a big improvement boosting the input before the aux. input on a Harley. I thought it sounded good before, and now the stereo separation and sound quality, is as if I installed a new radio !!!The best part is installation took lest than an hour.Pop of the front fairing, hard wire it and put the fairing back on.I had to turn down the audio output of Sirius dock and play. Before the volume control of the Harley was half way, now just two lines of volume !!!How this small booster can make such a big improvement, is unbelieveable !!!Bill  

I love my new Boostaroo, it makes everything sound great!I have Klipsch Custom 3 earphones and an iPod Touch, there is a substantial difference in the separation, whoo hoo!!  

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, you can use this as amp in your car high amplifier no need to buy an amp for your car use this. 100% no scam or lies about this product.  

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, we COULD NOT use our DVD players in flight because the volume was so low. Your product saved the day for us.  

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.  

Works great, thanks!
 

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.  

Very happy with my amplifier. Just wanted to let you know.  

GREAT CUSTOMER SERVICE. I recently purchased a Boostaroo Original for use
with my CREATIVE ZEN MP3 player and TORK XPRO helmet speakers. I found the
Original just didn't provide the volume increase I was expecting. I
contacted the customer service department and explained my situation.
Their support guy advised me that it was underpowered for my MP3 player/speaker
selection and the Boostaroo Revolution was the appropriate unit for my
use. I was immediately offered the option of a refund for my purchase or an
exchange for the Revolution. Really refreshing to find excellent customer
service like this!  

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. Now, if we can just get Boostaroo to give some seperate Bass and Treble control I am set for life. Thanks "Boosty Boys."  

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, and now I would be lost without it. I would not be able to work as a transcriptionist if my boss hadn't sent me to your site. Thank you.  

I JUST TRIED YOUR NEW AMP,ALL I CAN SAY IS (WOW) WHAT A DIFFERANCE.
I HAD TO TURN THE SOUND ON MAY LAPTOP
ON BOTH MY SPEAKERS AND HEAD PHONES.
IT IS EVERYTHING YOU SAID IT WOULD BE  

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. And by the way, your customer service is tops as well.

Thank you.

I am profoundly deaf and for a long time just used my Boostaroo with an iTouch. Last night I tried it with my Apple lap top and for the very first time in the five years I have owned it, I actually heard things.  

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, the "old" bostaroo (with transparent body) and the new one for portable and also one with the 12 VDC-cords. Bettest in my opinion is the old one, crisp sound with deepest bass! The new one has one big disadvantage: the used AAAA-cells are not easy to find in Europe. AAA are more common and should be planned for next product-update.  

I'm VERY disappointed in the product that I purchased, was informed that this product would BOOST volume by 100%.NOT! Also not as compact as I thought it would be.Will return for hopefully more POWERFUL one. The shipping speed was EXCELLENT.  

I have used 2 Boostaroo products on many long flights with Bose Quiet Comfort 2 headphones. Works perfectly. Thanks for a great product.  

I recently purchased the Boostaroo Revolution® Mini Headphone Amplifier & Sound Enhancer (R234-2). I wanted to use this with my amazing speaker pillow from Sleepsonic.com. There are times when I prefer my volume a bit louder than most people and this great little gadget did it for me. Now I have it all... great comfort and great sound. Thank you!  

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, and your prices are very reasonable. THANK YOU!!  

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, now have to turn my Ipod Volume DOWN!!!
I LOVE IT
.....The Boostaroo is what I have been dreaming of for 5 years.......  

Received your order, The Boostaroo Is absolutely amazing. Best thing I have spent on my iPod in 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, not need for adapters. I will be getting another one after the holidays to boost my Sirius before the aux. input on my other Harly 2007 Ultra Classic...Bill Fort Lauderdale,Florida  

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!  

I received you product today, the Boostaroo Amplifier. I am very pleased with this unit, if works very well. I have hooked it up to my treadmill. Finally Led Zeppelin as it was meant to be, it really gives my work out a boost. Thank You.

I got my Boostaroo in the mail today, and I am impressed with how well it amplifies the sound going from my iPod to my stereo.  

Many Thanks to you and the inventor.
You did a wonderful job with packing and shipping it, Thank You.

WOW--Its small and POWERFUL!
No noise or distortion and very high
quality sound and high tech by all means! I use Sennheiser HD 595 headphones- It makes great headphones better! Its Well worth the price!
A more then reasonable price!

I want to tell you, I'm more then deeply impressed by this quality product
and your kind customer care and service. I highly recommend this to anyone who deeply loves music and uses a CD Player, MP3 CD Music, iPod, etc...

There are other amps on the market, but I'm so glad I got this one. It really sounds like your are in the studio or concert. The sound quality is simply Amazing!  

Finally got my boostaroo today! Not that I have been waiting very long, a couple of days, even tho I live in Sweden. But I have been very anxious and nervous. Would it be what I expected it?

Order it. Thats all I can say. If you have any doubts, trust me. It boosts volume ALOT and the sound is still clear. If there is anything I could wish for more, it would be a rechargable batterypack. Except that its the perfect product!  

I just received my Boostaroo Revolution today and tried it out. It's fantastic! I have a pair of very high end, 300 ohm headphones, and with any portable player, the volume was far too low to listen to. But with your exceptionally compact, light weight Boostaroo Revolution, I now have the volume on my player set only half way up. Any more is just too loud. Best of all, it sounds like a high end amplifier. I can't believe the price!
I have been waiting for such a product for years, and your wonderful product is exactly what I was looking for. This is the portable headphone amplifier to buy. Congratulations on a job well done!  

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. Now, we can once again enjoy our "in-flight movies". Thanks for a great product. The only downside....the batteries are a bear to install/uninstall.  

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. YOU, Boostaroo, have solved a long standing problem while using my Mac Pro with Windows and staying away from "overkill" -- more expensive amps (Only for one platform!).  

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 expected

Good 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 expect you know that the European Union Nanny State, in its wisdom, has decreed that all music players which use headphones have a restricted maximum decibel output. So we Europeans have a miserable maximum volume on our ipods, mp3 players, etc.

You have blown a hole in this legislation - all power to your elbow!!  

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!  

I have been using my Sportster Sirius radio on my motorcycle with a MP3 player for a receiver for while with a lot of aggravation. The FM signal put out by the satellite radio is so weak, even at two feet away the reception was awful at times. I have been to at least 5 electronics stores and searching the internet off and on for fix for months with no luck. I kept being told, "the only way to pick up the signal is with a FM receiver." By chance I checked with TSS radio and was hoping for a miracle. I got it. The audio out on the sportster has no amplifier, only a direct link to a radio that will then boost the volume. The tss rep suggested I try a Boostaroo. Plugged it into the audio out, plugged my headphones into the Boostaroo and wow! I just wanted to let people know about this because I have found this information NOWHERE. Even folks selling satellite kits for bikes or Sirius themselves. You have a great product and finally cured my problem. Please let folks know about the satellite application. I promise I will let as many people know about it as I can.  

Got one about 3 years ago, and just wanted to say, I love it. Just tonight felt remiss in saying how well it works.  

I am studying medical transcription and there are times when the recording is so low that it is difficult to hear, even with the volume turned all the way up. After searching the internet for something that would help, I came upon your website and purchased the Boostaroo for 39.95. I must say that it was the best 40 bucks I've spent in a long time. The sound boost is incredible, I can hear everything now. By the way, when you make a product that will allow me to understand mumbly doctors, please let me know. LOL. Thank you so much for an excellent product. Sincerely, Tammy Bean  

LOVE your product on my long motorcycle rides. Many repeat purchases and have passed on tips to many others to buy your good stuff!  

The Boostaroo Revolution is a great product. I just purchased my second one.  

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.  

How many times can you say "THANK YOU" to such a great company with super people with such outstanding products?
Well, im doing it again! THANK YOU!!!
A few months ago i left a testimonial about my purchase of the R234 BOOSTAROO REVOLUTION MODEL and how much i loved the improvements they made to it over the ORIGINAL BOOSTAROO which i had been using for several years listening to MP3 tunes and navigation while riding my TRIUMPH motorcycle as i am a full time bike rider and music and bike's just go together, and although both units done the job they had one flaw....BATTERIES!
So after many phone calls to them about what us bike riders needed they listened and delivered!
With the NEW 12-VOLT BOOSTAROO REVOLUTION MODEL R234-MC (so no more searching for AAAA batteries like the portable REVOLUTION uses when your on the road and they go dead and your in a small town at a small mom and pop store who has never heard of such a battery and you dont want to ride without your tunes!).
So after waiting (with no patience...just ask Laura and Chase at Boostaroo!) i recieved the first 12-VOLT R234-MC REVOLUTION they shipped out, and the same day i recieved it i installed it on my bike and am very excited and happy about it as its almost everything i asked for, and the only reason im saying almost everything is the fact that this unit is not waterproof, but here is a few mod's i did to help that matter, the first thing i did since this unit has two audio output jacks and i only use one i put a small smear of clear silicone on one of them to keep water out of it, the other since this is the first production run of them it still has the battery compartment lid on back (which Chase told me will be removed on the later production models) i sealed it off with silicone also, so these few things didnt make it 100% waterproof it did help the water situation but i still advise to remove it in a rain down pour or when washing your bike, another mod i did was to remove the CLA (cigarette lighter adapter) and hard wire it in to my wiring harness on a circuit that is controlled by the ignition key switch so when i turn my key off the R234-MC goes off without having to unplug the patch cable that runs to it from my audio source, also i added to the positive side of the wire a sealed ATM fuseholder and installed a 2-AMP ATM fuse just in case (a not needed mod but since my bike uses all ATM type fuses is why i used that type of fuse but you can use other styles if desired), or if your bike has POWERLET PORTS (which my bike has three but i use them for heated cold weather riding gear and other needs) you can remove the CLA and install the POWERLET PLUG and use it that way or if your bike has a CIGARETTE LIGHTER PORT you dont have to do anything and POWERLET PORTS and CIGARETTE LIGHTERS PORTS are fused already!
These was things i just wanted to do but was not needed to take advantage of this great new product from BOOSTAROO and as the first peron to recieve one and use one i wanted to be the first to give it a write up and big AAAAA+++++!
So again i just want to say thank you BOOSTAROO for another great product and i guess they will be happy not to hear from me every other day now asking "IS IT READY YET!"
but what about that OPTIONAL WATER PROOF VOLUME CONTROL?
So all i can say now when the next version of the 12-VOLT WATERPROOF REVOLUTION MODEL is ready, they better have me on the list or i will be calling!
THANX A MILLION..Mike Ward in KY
 

I just bought boostaroo spliter amplifier and use it on my tv, i'm hearing impaired and this is the 1st product i'v purchased that really works, the volume is great, clarity is great.  

The first thing i have to say is THANK YOU! not just for the outstanding products from Boostaroo, but for the great people you deal with at Boostaroo! A big special THANK YOU to Laura in customer service and Chase in technical support, they are happy to talk with you anytime and answer any questions you ask and listen to your needs and wants for future products for us motorcycle riders as i think they are seeing there is a bunch of us out there and it could open up a whole new or larger market for them. Now for the products, i am a full time motorcycle rider and ride a new Triumph Sprint St sport touring bike and have been using the original Boostaroo for several years now listening to MP3 tunes and navigation in my Shoei full faced modular helmet with speakers installed from my Garmin Zumo 450 Gps and it worked great, but just a few weeks ago i purchased the new Revolution R234 model (just because i like to keep up with technology and improvements) with the optional volume control and it is like night and day compared to the original model and you will need the volume control to turn it down a little because the new model really pumps up the volume, if you ride a bike i highly recommend the new Revolution as you wont be sorry for the small investment for a quality product with such great large results. And as a bike rider i gave them a little input on what we need and they listened, as we need a waterproof Revolution, a optional waterproof volume control and a 12-volt direct wire model (which they tell me a 12-volt version will be available soon and and i cant wait until it does as i want one now! i hope the unit will turn off though when you turn the ignition key off or has a on-off switch as that would be a great feature and a big plus even for the portable battery powered model) But for now im happy with what they offer with no complaints (except for the no on/off switch on the Revolution, but i can live with it) So again all i can say to everyone no matter what you will use it for is "BUY ONE" you wont be sorry, THANK YOU AGAIN BOOSTAROO FOR THE GREAT PRODUCTS AND CUSTOMER SUPPORT TEAM!  

I recently got my Boosteroo, and attached it to the side of my helmet, just above my MP3 player. What a difference ! Now I can hear my tunes at cruising speed... Nice little device...Dennis, Red Bluff, Calif.  

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!
