The Sonos ZoneBridge 100 makes setting up an all-wireless Sonos system wonderfully fast…and easy. Instead of using a ZonePlayer, simply connect the ZoneBridge to your router to instantly activate the SonosNet wireless mesh network. Now all your ZonePlayers and Controllers can work wirelessly and be put anywhere in your house. It’s the ideal solution if your house doesn’t have Ethernet wiring or your router is in a room where you don’t want music.
