Sonos
SONOS is the first and only digital music system that lets you play all your digital music, all over your house and control it all from the palm of your hand. Best of all, you don't need a PC in every room, a music server or a wireless network. Just a Sonos ZonePlayer and speakers in the rooms of your choice and a Sonos Controller in hand to access all your digital music, no matter where it's stored on your PC, Mac or Network Attached Storage box.
