Quick verdict: strongest when you already own Sonos
Sonos Ace Ultra is most convincing for someone who wants one pair of headphones for commuting and private TV listening through an existing Sonos soundbar. Better noise cancellation is a useful upgrade, but the catch is its price: you are paying for system features as well as headphones.
Music-only buyer? Compare Sony WH-1000XM6 before committing. Already happy with the original Sonos Ace? TV Audio Swap alone is not a reason to replace it.

Better ANC, with a less clear-cut music verdict
Kate Kozuch at Tom’s Guide found particularly effective suppression of low-frequency travel noise. What Hi-Fi? also reported a substantial ANC improvement over the original Ace, while noting that nearby speech and abrupt sounds still get through.
The listening verdict is less unanimous. TechRadar found the new model more musical and worthwhile even without Sonos speakers. What Hi-Fi? liked its fuller sound but preferred Sony WH-1000XM6 for rhythmic precision and expression. Treat those as reviewers’ listening impressions, not an objective winner in every room.
Call quality deserves the same caution: Tom’s Guide heard improved voice isolation; What Hi-Fi?’s roadside test still favored Sony for blocking background noise. For frequent outdoor calls, that disagreement matters.
The practical takeaway: buy primarily for the combination of ANC and home-system convenience. Audition it against Sony if music detail is your priority.

Wi-Fi linking is not the same as lossless streaming
Separate listening paths. Early Access headphone linking sends compressed stereo; TV Audio Swap is a different feature.
Headphone linking is available now as opt-in Early Access. It needs Wi-Fi, the Sonos app and at least one compatible Sonos product active in your system. Start music in the Sonos app, use line-in audio or your local library, then select the headphones or hold their Content Key.
Sonos lists important exclusions: AirPlay, Bluetooth sources and music started through direct-control services such as Spotify Connect cannot be handed over this way. Headphone linking currently sends lossy stereo, without lossless or spatial audio. Only one headset can have an active linking session.
That does not remove the separate lossless options. USB-C audio and aptX Lossless Bluetooth remain available with compatible sources. Do not assume an iPhone supports aptX just because it pairs successfully.

Private TV listening: check your soundbar first
TV Audio Swap requires a supported Sonos home-theater speaker, setup in the Sonos app and the speaker’s Wi-Fi enabled.
TV Audio Swap supports Arc, Arc SL, Arc Ultra, Beam Gen 1, Beam Gen 2, Beam Ultra and Ray. Both the original Ace and Ace Ultra can use it. There is no need to buy a new Beam Ultra solely to listen privately.
It transfers the home-theater audio to the headphones. Spatial audio and head tracking are separate settings; an Atmos result also depends on the source content and TV setup. Two supported headsets can share a TV session, but head tracking switches off while both are connected.
What Hi-Fi? successfully used a Beam Gen 2 in its review and described an immersive film presentation with TrueCinema. That is a useful firsthand report from its test room, not a Decively test.

Battery and comfort: the useful everyday checks
| Check | What the evidence says |
|---|---|
| ANC runtime | Sonos claim: up to 35 hours at moderate volume. |
| Quick charge | Sonos claim: up to 3 hours from 3 minutes, starting at empty. |
| Independent use | TechRadar broadly matched the 35-hour claim; no separate controlled linking-runtime result reported. |
| Parts | Replaceable cushions and battery; check local replacement availability. |
The table’s runtime and charging figures depend on volume, settings and listening mode. They are manufacturer conditions, not guarantees for every use.
At 322 g, fit matters more than the specification sheet suggests. What Hi-Fi? found the softer pads comfortable over longer sessions, but noted that the headphones swivel flat rather than fold into a smaller bundle. Replaceable cushions and a replacement battery are useful ownership advantages.

Who should buy it — and who should wait?
A good fit
You already own a supported Sonos soundbar, regularly watch TV without disturbing someone else, and also need strong ANC for travel.
Compare or keep what you have
You mainly listen to music, prioritize outdoor calls or compact packing, or already have an original Ace that does your TV job well.
Sonos launched Ace Ultra on September 29, 2026, with a US list price of $449. Official US, UK, Canadian and Australian product pages are live; check local stock, delivery and warranty rather than assuming one store serves every reader.
At full price, compare the actual cost with Sony WH-1000XM6 and a discounted original Ace. The Ultra’s added value is strongest when you will use its Sonos integration. Do not buy it on the assumption that Early Access will later gain lossless linking.
See our wireless-headphones buying guide and Sony WH-1000XM6 vs Bose QuietComfort Ultra 2 comparison for the wider decision.

Two questions before you order
Do you need Sonos speakers to use Ace Ultra?
No. Normal Bluetooth listening and wired audio work independently. A compatible Sonos product is required for headphone linking, and a supported home-theater speaker is required for TV Audio Swap.
Does headphone linking play lossless or Dolby Atmos music?
No, according to Sonos’s current limitations. It uses compressed stereo. TV Audio Swap and compatible wired or Bluetooth listening have different capabilities; do not combine them into one specification.
Research method: official product and support documents cross-checked with three independent early reviews. Long-term reliability remains unproven this close to launch. No product score, customer rating or Decively firsthand test is claimed.
