Leaked design details suggest the Sonos Ace Ultra features deeper ear cups and a revised microphone layout compared to the original 2024 Ace. Sonos spent 2024 playing the curious newcomer — $449, two colorways, no 3.5mm jack, and a pair of headphones that felt more like a proof of concept than a full commitment. Now, barely a year later, FCC filings and leaked images reportedly point to the Ace Ultra arriving this September. That turnaround speed alone tells you something. This isn’t a colorway drop. The rumored addition of Wi-Fi support — in a pair of over-ear headphones — signals that Sonos is done dabbling and ready to compete seriously in the premium ANC space.
What the Leaks Actually Show
FCC filings and leaked images reveal meaningful hardware changes, but core audio specs remain unconfirmed.
According to regulatory filings and related coverage, here’s what’s reportedly different from the original Ace:
- Deeper ear cups and a repositioned wear sensor, visible in leaked images
- Revised microphone design — a thicker, shorter pill shape compared to the original Ace
- Five colorways reportedly planned, up from the original model’s two
- No 3.5mm jack (again), but the package reportedly includes both a 3.5mm-to-USB-C cable and a USB-C charging cable
- Sonos Voice Control support indicated in the FCC filing
Coverage of the FCC documentation reportedly points to Bluetooth plus 2.4 GHz and 5 GHz Wi-Fi — unusual territory for over-ear headphones, and the detail that shifts the entire competitive conversation. None of these details have been officially confirmed by Sonos.
The Sony Problem
Ecosystem depth, not spec sheets, appears to be Sonos’ actual strategy against a rival with a decade-plus head start on ANC.
If you already have Sonos speakers in three rooms, the Ace Ultra reportedly wouldn’t just be headphones you reach for on the commute — it would function as another node in your home audio setup. That’s a meaningfully different product proposition than anything Sony is offering. Sony’s WH-1000XM6 is the named rival in coverage, and it’s a formidable one. Sony has spent years refining ANC to a level that still sets the benchmark for most buyers. Adding competitive pressure from below, Sony is also reportedly launching the cheaper WH-1000XM4C, squeezing the premium segment from both directions.
Sonos’ apparent answer isn’t to out-spec Sony on noise cancellation — it’s to make the headphones indispensable to listeners already inside the Sonos ecosystem. If the Wi-Fi rumors hold, the Ace Ultra becomes less a standalone headphone and more an extension of your living room.
Pricing remains the unresolved tension. The original Ace launched at $449; the Ultra will likely land at or above that figure. If you’re already invested in Sonos at home, the calculus here is genuinely different from everyone else’s — and that might be exactly the point.
