Sonos on Tuesday named its home audio software Sonos 27 and said it will add opt-in generative AI controls, including an in-house voice assistant, an open hook for third-party agents such as ChatGPT, and later user-built custom agents. At a New York event it also unveiled two devices built to sit inside that system: the $449 Ace Ultra headphones and the $699 Beam Ultra soundbar.

Opt-in AI for the whole home

Sonos 27 adds a first-party voice model, an open MCP hook for ChatGPT and other agents, and custom personas later — shipped as early access after the 2024 app failure.

What owners welcome

AI is opt-in, with a hardware microphone cutoff and no extra voice subscription. MCP is an open connector rather than a single locked assistant.

What still nags

S1 gear is excluded, custom agents wait until 2027, Google Assistant is still missing natively, and many owners wanted a stable app more than another assistant.

Leave it off if you want — that is the new release rule.

Opt-in · Early access, not a forced dump

Mic cut · Hardware switch breaks the circuit

S2 only · Compatibility list still unpublished
