Sonos is an American Audio company based in Santa Barbara, California. It was founded in 2002 by John MacFarlane, Craig Shelburne, Tom Cullen, and Trung Mai, and is currently run by Patrick Spence. Sonos is widely known for the line of smart speakers it develops and manufactures. Sonos products are designed to last for five years from the last date of production. While operable, Sonos speakers play music simultaneously in multiple rooms.

The company has partnered with several dozen companies that offer music services, including Pandora, iHeartRadio, Spotify, MOG, QQ Music, and Amazon Music. Sonos products work with the major voice assistants: Amazon Alexa, Google Assistant, and Apple's Siri. Sonos does not guarantee that any of these partnerships will be supported into the future.
