Griffin has a spanking new wireless speaker dock for your iPod known as the Evolve. All you need to do is place the iPod on the Evolve base station and you’re free to carry the cube-shaped speakers around without being restricted by those things called…wires. Each full charge provides up to 10 hours of playback time as long as you remain within a 150 feet radius. Each speaker comes with 4″ drivers, and you have to option to pick up additional units if you think a couple of these aren’t enough for your listening pleasure. The Griffin Evolve retails for $349 when they see a summer release.
