Urban Tool already impressed us with their line of futuristic gadget holders. This time they've added a pair of Bluetooth speakers and music controls to a pillow. This strikes us as something that would sometimes be useful, especially for listening to binaural beat sleep-optimization soundtracks.
Built-in microphones that let you take calls in addition to listening to music rounds out the functionality nicely, since having your arm fall asleep while on the phone is no fun. Its rechargeable battery is good for 10 hours of talk or listen time and 250 hours of standby. It costs $500, making it an order of magnitude more expensive than we'd ever consider paying.
