Sonos has unveiled a new overarching platform called Sonos 27 alongside a connecting technology named Sonos Fabric, aiming to resolve past software missteps that frustrated users. CEO Tom Conrad demonstrated how the new system allows compact Play speakers to temporarily join a Beam Ultra soundbar for surround sound without manual app configuration, before returning to standalone Wi-Fi operation when moved back to their original locations.
Sonos Fabric Enables Ultrasonic Mesh Networking for Surround Sound
During live demonstrations, Sonos products demonstrated the ability to detect when they are physically picked up and moved. According to the reporting, the hardware communicates ultrasonically with the new Beam Ultra soundbar, which then initiates a local mesh network to establish a low-latency surround sound system on the fly. This automation goes beyond previous multi-room stereo grouping by allowing temporary physical integration. Hardware and software are combined in a way designed to win back frustrated customers and attract new buyers to the ecosystem.
Did you know? Sonos Fabric allows portable and stationary speakers to communicate via ultrasonic signals, dropping the need for manual app configuration when creating temporary surround sound setups.
Open AI Integration and Sonos 27Voice Strategies
Under the leadership of CEO Tom Conrad, Sonos is pivoting toward practical choices and open architecture through Sonos 27Voice and Sonos MCP. Rather than turning speakers into generic smart home hubs, Sonos 27Voice focuses strictly on audio queries, routing complex or vague music requests to relevant tracks. Furthermore, the system incorporates an open approach: users can connect to outside AI assistants of their choice for non-music tasks, while third-party AI platforms like ChatGPT, Claude, and Siri can control Sonos speakers via Sonos MCP.
