FCC Filing Suggests Sonos Is Prepping an 'Ace Ultra' Headphone Sequel

A regulatory filing spotted by What Hi-Fi? points to a beefed-up follow-up to Sonos's first headphones, model number S52A.

Sonos may be gearing up to launch a second-generation version of its Ace headphones, based on paperwork the company recently filed with the FCC. The filing lists a device under model number S52A, and one included diagram — appearing to show an oval ear cup — carries the label "Sonos Ace Ultra," even though that name doesn't appear anywhere else in the documents.

The "Ultra" branding would line up with how Sonos has named other products in its lineup, most notably the jump from the Arc soundbar to the pricier, more capable Arc Ultra. If the pattern holds, the Ace Ultra could slot in as a higher-end option alongside or above the original Ace rather than a straight replacement.

The filing also reportedly includes a list of color options for the new headphones, though exact specs and features weren't detailed. Timing-wise, this tracks with comments from Sonos CEO Tom Conrad on a recent earnings call, where he hinted that new headphones were on the way this fall — putting a possible announcement just a few months out.

Why it matters: Sonos badly needs a win after a rocky software relaunch and slower-than-expected Ace sales, so how it positions a follow-up headphone matters for the company's momentum. An 'Ultra' tier also suggests Sonos wants to compete more directly at the premium end against Bose and Sony, rather than just iterating on its debut design.
