Sonos delivers a multi-room solution that is easy to use, yet very powerful.
The product line consists of the standalone speakers Sonos Play:5, Play:3 and Play:1. The stationary Connect:AMP (which has an integrated amplifier) and Connect. The sub-woofer SUB and PLAYBAR for home theaters.
Connect and Connect:AMP (previously ZonePlayer 90 and 120) are stationary units that can be connected to a receiver. Connect:AMP can also connect directly to speakers.
SUB is a sub-woofer that can work together with Play:5, Play:3, Play:1 and Connect:AMP.
PLAYBAR is a home theather speaker that has nine built in speakers and can be paired with a SUB an two Play:3s or Play:1s to get 5.1 audio.
The devices talks to each other on their own wireless mesh network, so no need for existing WiFi. This makes the setup very easy (no WiFi configuration at all) and the performance more stable.
The system does not require a running server on a PC. It is
totally stand alone.
One music unit or the Sonos network unit, Bridge, must be connected to the network router through an ethernet cable in order to setup the Sonos wireless network.
The audio quality is 16-bit/44.1 kHz which is CD audio quality.
Controling the devices
The devices only has buttons for play/pause/skip/volume and they lack screens on them so they require remoting software on either a computer, iPad or a smartphone to work properly.
Sonos has official and free remote apps for iPad, iPhone and Android. Sonos previously had a dedicated remote, the CR200, but it has been discontinued.

Sonos is AirPlay compatible when connecting the audio out and ethernet cable on a AirPort Express to the respective line ins on a Play or Connect unit. Sonos can then play the music in either one zone or many sones synced (Party mode). But it is not possible to target specific different zones like, first the kitchen and later the living-room. It is possible to target different zones by attaching them to ont AirPort Express each.
The Sonos units does not have music stored on them. Instead you play music from local network sources like a shared folder on a computer or a server. If you have an iOS device, you can play the local iTunes music on your Sonos devices.
You can also connect to a large number of online services like thousands of Internet radio stations or premium services like Spotify, Pandora, Rdio, Napster and more. Spotify for example gives access to millions of songs that can be streamed to different zones at the same time for 9.99$/month.
