Based on a new FCC filing spotted by Lowpass, one of the products it's unveiling at the event could be a pair of headphones called the "Ace Ultra." While the filing is heavily redacted, the Ace Ultra seems to have an over-ear design, similar to the original Sonos Ace launched in 2024. (The headphones in the image above are the Sonos Ace, and not the upcoming model.) The FCC filing also hinted that the device will support Sonos Voice Control, the company's voice assistant. Ace Ultra will likely be just one of the many AI-enabled products Sonos will unveil in the future.
