Griffin's oh so sexy wireless Evolve iPod speaker dock
now has a little buddy. Two actually: the $100 Cube Speaker and $30 Charging Base add-ons. The speakers operate at 433MHz and feature an internal lithium-ion battery for 10-hours (at "normal" listening value) between charges. And you can add as many speakers as you can afford. Our own hands-on from CES allowed us to walk about 100-feet from the base station before interference set in. Not bad considering the density of RF noise the speakers had to compete with on the busy show floor. Combined with the charger, the complete system could make for a quick, dirty, and expensive (the Evolve costs $299) wireless setup in your tiny dorm or garden apartment.
