Ceramic iPod speaker “Phonofone”, it uses no power!!!

Phonofone

The Phonofone is an unusual speaker for your iPod not just for its old-fashioned looks, only it uses no power.

Through passive amplification alone, these unique pieces instantly transform any personal music player + earbuds into a sculptural audio console. Without the use of external power or batteries, the Phonofone II inventively exploits the virtues of horn acoustics to boost the audio output of standard earphones to up to 55 decibels. Now let’s make this clear, 55 decibels is not going to entertain your party, but it’s fine for the office or next to the bed or or for a dinner party. Dimensions: 11″ x 9.5″ x 20″ (28 x 25 x 51 cm)

But honestly, if you want to get a great sounding set of speakers that you can crank up and rock out to, get a set of Bose.
