We've had MP3 watches for a while now, though they've never really taken off. Just a guess, but it might have something to do with those earphone wires dangling from your ears to your wrist. For his concept MP3 wristband, designer Nathan Davis took a cue from iriver and put in some Bluetooth action to get rid of the cables (though Kleer wireless tech might be a better choice for music). Much appreciated, Nathan.

The OLED display will go easy on the battery, and the display slides up to reveal the controls, though you can just twist the face to jog playback. But it gets cooler — each of the earphones has an adjustable curved shape that fits over the contours of your ear (picture after the jump). Sounds like worth getting just for those. Too bad we'll have to wait until somebody builds the thing. — Peter Pachal
