Battery-free iPod speakers
Shinza has launched the BoomBall, a new speaker system that connects to multiple devices such as Apple's iPod through a minijack connector. The speakers are spherical when stored and fold open to play, connecting only to the minijack output of the device using a single cable. The BoomBall doesn't require batteries or AC adapter, drawing all needed power through the sound input. Boasting a weight of 5.75 ounces and a closed size of 3.29 x 3.03 x 3.03-inches, the BoomBall speakers are available for $25 in black and white, with a similarly priced pink version to follow.

Low Output?
If it only draws power from the iPod then the actual output levels must suck.
