Sonos is an American developer and manufacturer of wireless home audio products, including smart speakers. The basic idea behind its products is Whole House Audio, i.e., to allow a household to play music from a variety of sources in multiple rooms simultaneously, so that different rooms may hear either the same music source in sync or different music sources.
The company was founded in 2002 by John MacFarlane, Craig Shelburne, Tom Cullen and Trung Mai. It is currently run by Patrick Spence.
Sonos has partnered with over 100 companies that offer music services, including Pandora, iHeartRadio, Spotify, MOG, QQ Music, and Amazon Music. Sonos products work with the three major voice assistants: Amazon Alexa, Google Assistant, and Apple Siri, although the latter is currently only supported through Apple's Home app. In 2019 Sonos acquired Snips SAS, a privacy-focused AI voice platform for connected devices with the goal to bring a music-specific assistant to its devices.
