NuForce Cube Portable Speaker

Physically, the Cube is very impressive. Sleek metal houses the speaker, giving it a reassuring heft while remaining plenty light enough for a mobile device. The height and the width both measure roughly 2 inches, with the length sporting an extra quarter inch. On the back, you'll find three ports: one USB port for hooking up the computer and two 3.5mm ports, one for a pair of headphones and one to go to your phone, MP3 player, or other portable device as an audio source.
