Sonos launches Sonos 27, a significant upgrade to its audio OS, featuring AI assistant support, a redesigned app interface, and enhanced multi-room capabilities, signalling a move towards more software-driven audio control without hardware replacements.
Sonos has started rolling out Sonos 27, a major update to its audio operating system that pushes the company further towards software-led control. The release adds support for external AI assistants, introduces a new in-house voice assistant focused on music and mood, and gives the app a redesigned interface intended to make larger multi-room systems easier to manage. Sonos said the update is being delivered as a free software upgrade for all Sonos S2 products, although not every feature will work on every device.
The most notable change is Sonos 27mcp, an early-access integration that connects Sonos systems with outside AI tools through the Model Context Protocol, including ChatGPT and Claude. Sonos says this lets users adjust playback from within the AI service they are already using, rather than switching between apps. The company is also preparing Sonos 27voice, an assistant it says has been tuned to understand the way people actually ask for music, including vague references to songs and requests based on mood, such as a dinner party or a winding down routine.
Sonos is also extending how its speakers and headphones interact with one another. The update brings portable surround support, which allows compatible Move 2 and other portable speakers to act as rear surrounds when placed near a supported soundbar, then return to normal portable use when moved away. A new headphone linking feature will let Sonos Ace Ultra connect directly to the wider system, enabling sound to move between headphones and speakers without relying on a phone being kept nearby. Sonos says both features are built on its Fabric system intelligence, which lets products sense and adapt to one another over time.
The app is being reorganised as well, with navigation split across Home, System and Search, plus swipe gestures, pinned rooms and a virtual volume knob. Sonos has said iPhone users will get lock-screen control, Dynamic Island support, Siri and Shortcuts integration, while iPad owners receive a refreshed layout. Later additions will include Presets and new system health views. In its own explanation of the release, Sonos said the aim is to make the platform improve continuously without forcing customers to replace hardware, a message Chief Executive Tom Conrad framed as part of the company’s broader product strategy.
