'Sonos 27' brings a refreshed UI to the app and lets AI agents control your system

Sonos 27 adds an OS update that lets any external AI assistant (e.g., ChatGPT) control playback, volume, and speaker grouping through a public MCP server and introduces Sonos Custom Agents for personalized models, personas, and voices. It also launches Sonos Fabric for automatic speaker-role reassignment, early-access headphone linking for Ace Ultra, and a redesigned app with persistent home, system, and search tabs plus speaker-pinning capability.
