Put your music on your wrist with the bem wireless Speaker Band. This colorful bluetooth speaker has the look of a chunky watch but it actually connects wirelessly to your phone and plays music. It has a built in microphone as well so you can use it to answer calls (kinda like a watchphone but without a display). It charges via a micro-USB port hidden beneath the speaker, good for about 6 hours of playback. Buttons on the side let you play, pause, answer, skip, and reverse. Comes in 6 funky colors for about $50. You could even pick up a pair and hold them up to your ears for personal surround sound.
