DESC: Welcome to the evolution of home audio. The Evolve speaker system comprises a charging base and two cube-shaped speakers. Talk about stereo separation - simply place the Evolve cubes wherever you want to hear the music. You can even move them into the next room with you. There are no entangling wires to hassle with. Each speaker cube has its own long-lived Lithium-Ion battery pack, delivering up to 10 hours of music between charges. Evolve even charges wirelessly: to charge the batteries, just place the speaker on its charging station. There is nothing to plug in, and nothing to unplug when you're ready to deploy the music. Each speaker features its own on/off switch, and an automatic sleep mode to conserve battery charge.
