iRiver Aquabeat - underwater MP3 Player

In Partnership with Speedo, iRiver created the LZR Racer Aquabeat – an MP3 player that operates underwater for up to 3-meter deep.

The player comes with 2GB of internal storage and supports MP3 and WMA file formats. Just like the shuffle, it does not feature any display; only basic controls such as play, stop, volume controls, and track controls. Battery life is said to last up to 9 hours. It is available in Japan for 12,800 yen (roughly $150).
