Getting music to all the rooms of your home can be an expensive task, especially if you have to run wires. Sonos has been selling network multi-room music systems for a while now that can stream tunes wirelessly to speakers in any room of your home. Yesterday, Sonos announced a pair of new wireless music systems and it has announced a software update.

The Sonos 2.6 update is available free to all Sonos customers. To entice users to install the new software update Sonos is offering free music worth $200 to those apply the free upgrade or register a new Sonos system. New features with the update include support for SonosNet 2.0 and MIMO, support for larger music collections on NAS or PCs, and support for Mac Leopard OS.

Sonos, a developer of wireless multi-room music systems, unveiled today a new device to help simplify setting up one of the company’s music networks in a home. The Sonos ZoneBridge is priced at $99.

The Sonos ZoneBridge is designed to be hooked to a router. One presses a button on the bridge device and it reportedly will “instantly” connect the SonosNet, Sonos’ wireless mesh network. Sonos says the ZoneBridge can also be used as a wireless extender by placing one between the remote music zone and the rest of the Sonos system.
