AirCurve turns your iPhone into a no-power-drain alarm clock on your nightstand, or a mini sound system that never needs batteries or adapters. This cleverly designed acoustic amplifier for your iPhone collects the sound from the built-in speaker of your iPhone, amplifies it in coiled waveguide within the base, and projects it into the room. The waveguide has been engineered to deliver amazing amplification - youll swear there are full-sized speakers in there. Included pass-through slot allows you to charge and sync your iPhone using your own cable. And AirCurves see-through translucent polycarbonate body lets you appreciate the graceful curves that do all the work
