SONOS is a US company founded in 2002 to pioneer wireless audio systems and has assumed a position as the undoubted market leader. The Sonos wireless Hi-Fi audio system delivers a full-bodied sound that’s crystal clear at any volume as well as access to an almost unlimited amount of music from a wide variety of audio sources. It combines Hi-Fi sound quality and rock-solid wireless connectivity in a smart system that is easy to set up, control and expand. The system is controlled with one simple app, developed in-house by Sonos and subject to frequent free updates offering the better functionality. Multiple zones can be played independently of one another or simultaneously.

There are three main types of players in the Sonos system: all-in-one speakers such as the Five, One and Move, the Port for integrating other audio systems into the Sonos network, and the Sonos Amp for use with any passive speakers (including in-ceiling speakers). There is also a range of home cinema components to complete the system.
