Multi-Room Music System 
The Sonos Wireless HiFi System allows for streaming of music from internet sources, in multiple rooms within range, via wi-fi (802.11). Expansion can be achieved through the addition of the wireless bridge, which allows for greater range. Control of the system is available by apps for Android and iOS platforms, and Kindle Fire.
There are two main players in the Sonos Music System: all in one speakers and components. Components connect directly to unpowered speakers CONNECT:AMP, or to an amplifier/receiver CONNECT, which allows existing speakers to become Sonos rooms. All-in-one speakers allow any room with a power outlet to play audio. There is also a wireless Subwoofer that connects to any all-in-one speaker or amplified component.
The CONNECT:AMP (formerly the ZP120, successor to ZP100) has a reduced footprint, a 2x55 watt RMS amplifier (now Class D rather than analog), analog and digital audio out ports, 2 instead of 4 Ethernet switch ports, as well as the upgrade to SonosNet 2.0. Like the ZP100/ZP120, the CONNECT:AMP has speaker posts for direct hookups to speakers and a sub-woofer out.
The Sonos Play:5, formerly known as the S5, is a Zoneplayer with integrated five driver speaker system. It features a built-in two-port Ethernet switch. Also includes 3.5 mm headphone connection and a 3.5 mm line in.
The CONNECT (formerly the ZP90, successor to the ZP80) is an amp-less ZonePlayer that includes optical out, coaxial digital out, as well as analog RCA inputs and outputs. It has a built-in two-port Ethernet switch. The CONNECT/ZP90 upgraded the wireless to SonosNet 2.0.
The Sonos SUB integrates itself wirelessly in the rest of the Sonos ecosystem and works with Play:3, Play:5 and CONNECT:AMP. It features two force-cancelling speakers positioned face-to-face to each other and the system automatically adjusts audio settings when it gets connected to other Sonos speakers.
Audio inputs with digital encoding on players (except PLAY:3) allow for connection to external audio sources including MP3 players, mobile phones, CD players, TVs, DVD players, VCRs, and radios. The players with multiple Ethernet ports can be used as virtual Ethernet connections for normal network traffic: network traffic is bridged silently between all the players in a single system. This means stream external sources can be streamed all over the house.
The system also comes with the Desktop Controller that supports Mac and Windows. There is no supported or actively developed controller for Linux, and the latest versions of the Desktop Controller are not supported under Wine.
The Controller for iOS is a free app that allows an iOS device to become a controller for Sonos via an existing home wireless network. The app supports all generations of iPhone, iPad and iPod touch.
The Controller for Android is a free app that allows an Android device to become a controller for Sonos via an existing home wireless network. The app supports Android v2.1 and up.
Wireless mesh network 
Multiple ZonePlayers in a single household will connect to each other on a proprietary peer-to-peer synchronous mesh network using AES encryption. This network, known as SonosNet, allows music to be played simultaneously in separate zones. A single ZonePlayer or ZoneBridge must be wired to a network for access to LAN and Internet music sources. SonosNet 2.0 integrates MIMO on 802.11n hardware, providing a more robust connection. A consequence of this technology is that every Sonos player or bridge has to constantly keep up a wireless connection, even when in standby mode or connected by cable. Sonos devices do not have power buttons. The company claims that they consume between 4 and 8 Watts in standby mode.
Music sources 
The system can stream music from most SMB share (such as a Microsoft Windows or Macintosh file share or a NAS drive that supports CIFS/SMB protocol) to a stereo. NAS support also includes Apple Inc. Time Capsule. A NAS solution provides a computer-free solution to accessing music. It can also stream multi-room audio in many formats including MP3, AAC, Ogg Vorbis, FLAC up to 16 bit / 44.1 kHz, Apple Lossless, WAV, AIFF and WMA. While Sonos was able to stream Plays For Sure protected WMA files up to version 3.6 of the Sonos firmware, it does not support DRM FairPlay protected AAC files from Apple (however, Apple's gradual shift to DRM-free music makes new iTunes music playable in most markets), see iTunes Music Store. WMA lossless and RealPlayer Audio are also not supported.
With a broadband connection, the system includes access to a variety of audio content completely independent of a computer. The system ships with thousands of radio stations and shows from the Internet via TuneIn. The system also features 30-day trials for Napster, Rhapsody and Pandora as well as a 14-day trial of MOG (online music). The Pandora, SIRIUS, MOG (online music) and Rhapsody services are restricted primarily to customers based in the United States. Napster and Last.FM are also available in Germany and the United Kingdom. Napster is no longer available to Canadian customers. Stitcher Radio is also available on the system. Last.FM scrobbling is available worldwide. On September 29, 2010 the Spotify music service announced support for Sonos in all countries supported by Spotify.
