This combination watch/MP3 player was designed from Geil with the sports enthusiast in mind. It is available in 256MB, 512MB, or 1GB version supports Bluetooth 1.2 for the headphones. It can playback MP3, WMA, WAV and ASF. There are different colored interchangeable bands. All is good except for the fact that it is only USB 1.1. Come on, Geil, you give us Bluetooth support for headphones but still make us chug along as USB 1.1 speeds?
