Great Little Item!

If you need to boost your sound from any item that has a 3.5 plug in...this will do the trick. I plugged this into my ipod and cell phone and was able to use a splitter so that my wife and I could use our headphones when we travel to listen to our music. Works great with or without a splitter. Highly recommend. M Pousson

Great addition to your audio, with a few small caveats.....

This is a great little gizmo for anyone looking to boost up the music of their portable devices. It does exactly as advertised. Makes the sound better without having to put up the volume all the way.

This is what I used it with:

Media Player: Archos 605 80GB wifi
Headphones: Sharper Image Quiet Place FJ453, which I then will be using it with Grado SR-80s

As I mentioned, there are a few caveats to this:

- The battery cover is HARD to take off with just your hands. I recommend using a flathead screwdriver or something similar.

- The batteries. This uses AAAA batteries. Yes, that isn't a typo. There are such things as AAAA batteries. They aren't as readily available as AAs and AAAs, but I've heard you can purchase them at Staples and other office stores. I bought packs of them from ebay for cheap.

- These only work with Higher-end phones. Some people have complained of a white noise/feedback sound. If you use lower-grade phones, you will hear this noise. This is when you have to use the original boostaroo. Upbeat audio has created a list of which headphones are suited for each of their devices [...]

In conclusion, I recommend this only if you have high-end headphones and don't mind AAAA batteries

How to get cheap AAAA for the Revolution!

Just a small tip to get AAAAs for cheap:

Take apart a 9v battery, and boom, you have 6 cheap but great AAAAs that work awhile in this!

I've had much better luck Energizers than Duracells, however.

Does what it says - AMAZING !!!

I'm using high end Etymotic ER4P earphones (27ohms), and a Treo mp3 player running PocketTunes. This amp is amazing. It not only boosts the volume but notably increases the bass as well. In the past the EQ on my player was kind of useless, but now with this amp I can really use the EQ and dial in the sound just how I like it. The amp seems to slightly muffle the sound a bit, but my music is overall warmer sounding now. Basically it reminds me of the warm sound of listening to a tape, but with none of the downsides of a tape recording.

UNBELIEVABLE

FIRST I PURCHASED THE ULTIMATE EARS TRIPLE-FI IN EAR HEADPHONES FOR MY NOT SO EXPENSIVE MP3 PLAYER. THEY SOUNDED JUST AS ADVERTISED, "LIKE BEING IN A SOUND STUDIO". THEN I PURCHASED THE BOOSTAROO REVOLUTION AMP, THE DIFFERENCE THAT THE AMP MADE WAS INCREDIBLE. I USE MY MP3 MAINLY WHEN I RIDE MY HARLEY DAVIDSON, NOT THE QUIETEST MOTORCYCLE AROUND AS MOST PEOPLE KNOW. WITH ONLY ONE EAR PIECE IN, AS THE CALIFORNIA LAW REQUIRES, THE SOUND VOLUME AND QUALITY IS AMAZING. WHEN I GET TO USE BOTH EARPHONES IT IS NOTHING LESS THAN EYE POPPING SOUND. HIGHS AND LOWS ALIKE. I CAN ONLY IMAGINE IF ANYONE IS UNHAPPY WITH THIS PRODUCT IT CAN BE NOTHING LESS THAN A FAULTY UNIT OR VERY POOR QUALITY ELSEWHERE IN THE SOUND SYSTEM.
