Sonos is an American audio technology company founded in 2002 in Santa Barbara, California, by John MacFarlane, Craig Shelburne, Tom Cullen, and Trung Mai. Originally incorporated as Rincon Audio, Inc., the company rebranded to Sonos in 2004. Sonos pioneered wireless multiroom audio, allowing listeners to synchronize music playback across multiple speakers over Wi-Fi. The company holds over 4,000 patents and has introduced technologies including Trueplay room-tuning, stereo pairing, and Dolby Atmos spatial audio.

The Sonos product line spans wireless home speakers (Era 100, Era 300, Five), portable Bluetooth/Wi-Fi speakers (Move 2, Roam 2), soundbars (Arc Ultra, Beam, Ray), subwoofers (Sub 4, Sub Mini), components for custom installations (Amp, Port), architectural in-wall and in-ceiling speakers, and the Sonos Ace wireless noise-cancelling headphones.

The company collaborates with Grammy- and Oscar-winning producers and mixing engineers — including Giles Martin and Manny Marroquin — through its Soundboard program to fine-tune speaker performance against professional studio standards.
