Audio enthusiasts might soon get a new gadget to look forward to, as newly surfaced documents from the Federal Communications Commission have revealed hints about the successor to the brand's inaugural headphones. The regulatory filing submitted by Sonos, Inc highlights an upcoming wireless headphone model designated by the model number S52A.
Along with the S52A designation, one of the submitted paperwork pieces displays an oval diagram, likely representing the ear cup, marked with the moniker Sonos Ace Ultra, even though the name does not appear anywhere else in the file. This naming convention mirrors the strategy Sonos previously implemented with its Arc and Arc Ultra soundbars. Furthermore, the documents outline an expanded palette of color choices stretching beyond the standard black and white of the original Ace, listing a total of five distinct hues: greige, shadow black, agave, blush, and sand.

The filings also point toward testing for local networks across both the 2.4 and 5GHz frequency bands. This capability could be intended solely for the television audio swapping feature seen on the original Sonos Ace, or it could potentially indicate that these upcoming headphones will support direct music streaming over Wi-Fi, much like the company's standalone speakers.
The emergence of this FCC filing for the Sonos Ace Ultra comes at a crucial time as the company works to solidify its comeback following a turbulent app redesign rollout two years ago. Addressing past shortcomings with improved hardware options, refined colorways, and robust connectivity features could signal a complete redemption for the brand's headphone lineup.
This development follows a hint dropped by CEO Tom Conrad during a third-quarter earnings call, suggesting a release sometime this fall. It has been over two years since the release of the original Sonos Ace, a launch that was unfortunately overshadowed by app integration troubles and buggy ecosystem performance, despite the hardware's comfort, stylish build, and capable active noise cancellation.
