An FCC filing points to new Sonos headphones coming soon

An FCC filing from Sonos points to new wireless headphones with the model number S52A, following CEO Tom Conrad’s hint that a successor to the Sonos Ace could arrive this fall. One document appears to show an ear cup labeled Sonos Ace Ultra, suggesting the company may extend its Ultra branding beyond soundbars.

A new high-end headphone model would signal Sonos’ continued push beyond home speakers into personal audio, despite the Ace’s mixed commercial start. If the Ultra branding is accurate, Sonos may be trying to position the product as a more premium refresh rather than a simple second-generation update.
