The Boostaroo Revolution R234 (R234-1) HD Headphone Amp/Sound Enhancer Offer an Incredible Listening Experience

The Boostaroo Revolution is the perfect addition for the audiophile at heart. The Revolution will give your audio an expansive 400% volume increase, while at the same time providing high definition sound. Our patented circuit breaks apart compressed audio signals into three separate audio channels. This effect not only produces a highly defined sound, but creates imaged surround sound as well.

The Revolution works with portable DVD players, MP3 and CD players, satellite radios, PC's, Laptops, and FM transmitters. The Revolution is an audio amplifier that separates the signal into individual stereo channels to drive 2 separate headsets or speakers.

Boostaroo Inline Aidio Amp

I use this on my motorcycle attached to my GPS/satellite radio to kick up the output from the device and split it out to headsets for the front seat driver and back seat passenger. It works as described and we have no complaint. The battery life is quite impressive.

Efficient and does what you want

I purchased this product in order to boost tahe sound on my iPod when riding my motorcycle. With headphones plugged directly into the iPod I was unable to enjoy music at any speed over 25-30 mph. With the booster in line, now I can listen to clear music sounds at highway speeds with no problem. A great product, reasonably priced.

Great little amp

I bought this product for something a little different, and it works perfect. I was wanting to use a voice modulator for a Darth Vader costume with a throat microphone, however it just wasn't loud enough even with the amplified speaker I was using. When I plugged this amp between the voice mod and my speakers, it worked perfectly and gave plenty of amplification, nice and clear.

I am a legal/medical transcriptionist and have been dealing with low volume on my computer often making audio dictations hard to hear. I ordered the Boostaroo and had to turn my computer volume down to 1/4. Amazing little gadget, so worth the money. Ordering was quick and easy, and the Boostaroo arrived in two days! Doesn't get much better than this!

Great little sound booster

This item has been perfect for my needs, which was to raise output loudness for a home training program. Crisp clear sound without distortion within safe auditory limits. Special battery wasn't hard to find at all.

Works but?

Adds very little volume (the claim is 400 x) not even double but it adds a headphone jack if your speaker doesn't have one
