Sonos is preparing to launch successor headphones this fall, according to an FCC filing that reveals the model number S52A and hints at a product called the Ace Ultra.

An FCC filing by Sonos, Inc has disclosed details about upcoming wireless headphones expected to arrive later this year. The filing identifies the device with the model designation S52A, with supporting documents showing an oval diagram—likely representing the ear cup—labeled "Sonos Ace Ultra." The news aligns with comments made by Sonos CEO Tom Conrad during the company's third quarter earnings call, where he indicated a new headphone release was planned for fall. The Ace Ultra would serve as a successor to the current Sonos Ace headphones. While the FCC filing provides the first concrete evidence of the new model, the "Sonos Ace Ultra" name appears only on the diagram and has not been officially confirmed by the company. Additional specifications and features remain undisclosed at this stage.
