Evolve is a truly wireless iPod sound system from Griffin Technology. Each speaker cube is equipped with a Lithium-Ion battery pack capable of 10 hours of playback. When the juice runs out you place the speaker on its charging station and just wait for it to fill up again. Easy as that.
The speakers has an effective range of 150 feet and besides the regular iPod dock the base unit sports composite and s-video out as well as in- and outgoing female RCA connectors for non-iPod devices.
