Sonos Ace Ultra over-ear wireless headphones appear in an FCC filing, according to multiple reports. The listing suggests Sonos is preparing a new product under the “Ace Ultra” name.

Both outlets say the timing points toward a potential launch in September, with one report specifically linking it to a Sonos event scheduled for that month. While the filings confirm the product’s existence and its regulatory documentation, they do not provide final details such as pricing, release date, or full specifications. As a result, the exact consumer availability window remains unconfirmed.

Engadget and Gizmodo frame the FCC paperwork as evidence of an upcoming headset, with Gizmodo emphasizing that the launch could happen “soon” and Engadget focusing on the appearance of the model in the filing. Neither source independently verifies additional features or official announcements beyond the regulatory document and the suggested September timeframe.
