iRiver SV-i700 Waterproof Case for iFP-700 Series MP3 Players

Listen to your MP3 player underwater. The fully submersible housing protects your player and makes it possible to listen to your favorite music or audio tours while you dive or surf.

1 earphones don't work when swimming
This was an expensive mistake. It's a good mp3 player and the case works fine... But the earphones don't work underwater. They are cones made of hard plastic with a short flange, too narrow to form a seal within the ear. As soon as water comes in, the sound is not audible.

2 Swimming aerobics in song
I made a review of this and the iRiver 799T 1gb MP3 player on the iRiver product page, giving the combination 5 stars.

I had been looking for a way to combine my enjoyment of pool aerobics and tunes ever since the new generation of small, portable audio flash-style players came into existence. It seemed like a natural to me. To my shock, every store I went into said no one made players that could be mixed with water.

I was thrilled when an Amazon investigation FINALLY revealed that H2O Audio understood my plight and combined with the iRiver 799T, my exercise program could become more fun and invigorating. (Pity the poor neighbors who might overhear as I sing-along.)

The case comes with everything you could need for storing, listening and carrying, and it's sturdy. During out-of-pool times you can swap the waterproof earphones with ordinary headphones, leaving the player in the case, if you choose.

3 It does what it says it is going to do.
Used with the IFP780 this product works as promised. It works for swimming laps in a pool at least. I have not tried it at a beach. I found the arm band to be kind of cumbersome but it still works if you put the device on a neck strap and hang it around your neck while swimming. I will say also that the volume has to be turned quite high on the mp3 player for the sound to come in good in the water. No problem but don't forget to turn the volume down again for land use or it will blast your ears out.

Now for some background. I bought what was supposed to be an underwater fm player long ago from Service Merchandise. That thing never worked at all but this proves that technology has come a long way. I guess I never thought about buying an underwater walkman like tape player way back then but now that technology is all mp3/wma H20Audio seems to have designed a good product to keep swimmers in a stream of music.
