Room to room music and wall to wall sound; the Sonos S5 is a killer sound system that liberates your music from hard drive purgatory. The S5 has been around for a little while; we’ve looked at some Sonos products previously on this show. What's new here though is an Android app that lets you control the music coming out of your S5 from anywhere on your wireless network. You can control multiple S5s, sync music between rooms, pair two S5s into a stereo array, listen to Internet radio, podcasts and more. It's a slick and well designed system and the speaker unit kicks out crystal clear, room-filling sound.
