The Sonos Ace Ultra looks like a serious premium noise-canceling headphone, but the available reviews do not prove it beats Bose’s current QuietComfort Ultra Headphones (2nd Gen) in a direct head-to-head test. Reviews describe a substantial step up from the original Sonos Ace in sound and refinement; Bose remains a strong ANC benchmark. At $449 on Sonos’s US product listing, the Ace Ultra’s clearest extra appeal is its Sonos system integration.
What’s new about the Sonos Ace Ultra?
The Ace Ultra is a distinct 2026 model, not a renamed original Sonos Ace. Sonos lists a 40 mm driver, Adaptive Active Noise Cancellation (ANC) powered by ten microphones, and up to 35 hours of listening with ANC enabled. It also advertises spatial and lossless audio, Dolby Atmos, dynamic head tracking, Aware mode, Bluetooth, and Adaptive EQ. Sonos’s US product page showed a $449 price when accessed; prices and availability can change.

Sonos says the Ultra provides “up to 2x more” ANC than the original Ace. That is a manufacturer comparison claim, not a standardized independent measurement, so it should not be read as proof of a particular reduction in noise or an advantage over Bose.
Crashes, No Sound, or Screen Glitches?

The listed package includes a travel case, USB-C-to-USB-C cable, and USB-C-to-3.5 mm cable, so neither of those cables is an obvious extra purchase. Sonos says three minutes of charging can provide up to three hours of playback. That is a best-case company figure, not a promise of identical results in every listening setup.
#1 Best Overall
- Sonos-designed driver for deep, rich, detailed sound.
- High-resolution wireless audio with ultra-low latency.
- Up to 2x more Active Noise Cancellation than Sonos Ace.
- Up to 35 hours of battery with ANC on.
- Adaptive EQ tunes the sound based on your fit and movement.
How does it compare with Bose QuietComfort Ultra?
The fair conclusion is that the Ace Ultra is now a credible premium rival, not that it has been shown to beat Bose. Tom’s Guide named the Bose QuietComfort Ultra Headphones Gen 2 its best overall pick in a separate 2026 ANC roundup. That guide is useful context, but it is not a same-test comparison with the Ace Ultra. Tom’s Guide’s 2026 roundup therefore cannot establish which model cancels more noise or sounds better under identical conditions.
Generation matters here. An earlier What Hi-Fi? comparison found the original Sonos Ace behind the first-generation Bose QuietComfort Ultra in ANC and sound. That result concerns different Sonos and Bose models; it should not be carried forward as a verdict on the Ace Ultra. The older comparison is historical context, not a current-generation scorecard.

| Question | What the available evidence says |
|---|---|
| ANC | Sonos specifies ten-microphone Adaptive ANC and makes an “up to 2x” claim against its original Ace. Tom’s Guide reports strong ANC, while its separate roundup selects Bose Gen 2 as best overall. No retrieved source establishes an exact-model, controlled Ace Ultra-versus-Bose Gen 2 result. |
| Sound | TechRadar says the Ultra sounds more open, detailed, and balanced than the original Ace, while noting some rivals still edge it in sound quality. This is TechRadar’s listening assessment, not a controlled Bose comparison. |
| Comfort and weight | Tom’s Guide describes the Ultra as comfortable and reports a weight of 322 g. The cited evidence does not provide a matched comfort comparison with Bose Gen 2. |
| Battery | Sonos advertises up to 35 hours with ANC on. A directly comparable battery result for Bose Gen 2 is not established by the cited reviews. |
| Calls | Tom’s Guide reports improved call performance. The available evidence does not establish a direct call-quality ranking against Bose Gen 2. |
| Wired listening and connectivity | The Sonos package includes USB-C and 3.5 mm cables, and Sonos lists Bluetooth. The cited material does not establish a complete codec-by-codec comparison with Bose Gen 2. |
| Sonos system features | The Ace Ultra can link directly with a Sonos system without a phone in range; Sonos lists this Headphone Linking feature as Early Access. Bose does not provide this Sonos-specific function. |
| Price | Sonos’s US listing showed $449. TechRadar reported launch pricing of $449 / £399 / AU$699. These are regional launch or listing figures, not a guarantee of today’s price or stock. |
What reviewers say about sound, noise cancellation, and comfort
Sound: a meaningful revision, not a proven class winner
After weeks of testing, TechRadar described the Ace Ultra as more open, detailed, and balanced than the original Ace, and called it a meaningful improvement. The same review says some competitors still have an edge in sound quality. Those are TechRadar’s listening impressions; they support the case that Sonos improved its earlier headphone, but not a claim that it outperforms Bose Gen 2 in a direct comparison. Read TechRadar’s review.
ANC: promising reports, without a Bose head-to-head result
Tom’s Guide reports strong ANC on the Ace Ultra. Sonos’s ten-microphone design and Adaptive ANC are concrete specifications, but a microphone count does not by itself show how effectively headphones handle aircraft noise, voices, wind, or changing environments. Because the available sources do not compare the Ultra and Bose Gen 2 under the same conditions, there is no sound basis here for declaring an ANC winner.
Rank #3
- Sonos-designed driver for deep, rich, detailed sound.
- High-resolution wireless audio with ultra-low latency.
- Up to 2x more Active Noise Cancellation than Sonos Ace.
- Up to 35 hours of battery with ANC on.
- Adaptive EQ tunes the sound based on your fit and movement.
Fit, calls, and battery
Tom’s Guide reports a weight of 322 g, comfortable wear, improved call performance, and battery life of up to 35 hours. Treat the comfort and call assessments as that publication’s review findings, rather than universal outcomes for every listener or call environment. Sonos’s battery figure is an “up to” claim with ANC on.
Does Sonos integration make the Ace Ultra worth choosing?
For existing Sonos owners, the standout difference is Headphone Linking: Sonos says the Ace Ultra can connect directly to the Sonos system without a phone in range. The company identifies the feature as Early Access, so its status and supported devices may change. Check Sonos’s product page for current feature details before buying.
Rank #4
- HEADPHONES | Featuring Dolby Atmos.
- SPATIAL AUDIO | Enjoy an industry-leading Dolby Atmos experience with dynamic head tracking.
- LOSSLESS AUDIO | Stream lossless audio over Bluetooth or via USB-C.
- ACTIVE NOISE CANCELLATION | World-class ANC neutralizes external sounds for maximum immersion.
- ALL-DAY COMFORT | Bespoke fit with plush memory foam, soft vegan leather, and a design that suits all head shapes, hairstyles, and accessories.
Tom’s Guide specifically found the headphone compelling for people with Sonos speakers who want to move from soundbar listening to headphones. TechRadar also identifies Sonos integration and movie listening as distinctive strengths. Dolby Atmos and dynamic head tracking add to the spatial-audio pitch, though the sources do not establish that every streaming service or listening setup will deliver the same experience.

It makes the most sense if…
- You already use Sonos equipment and value the prospect of direct headphone linking for listening from your system.
- You want a premium ANC model with spatial-audio features, and the improved sound described by reviewers appeals to you.
- You want both USB-C and 3.5 mm wired options in the box rather than needing to source those cables separately.
Look elsewhere if…
- Your top priority is choosing the proven best ANC performer according to Tom’s Guide’s current roundup: that guide selects Bose QuietComfort Ultra Headphones Gen 2, though it does not compare it directly with the Ace Ultra.
- You need a verified head-to-head winner on noise cancellation, sound, call quality, or battery life. The available reviews do not provide a controlled comparison of these exact current models.
- You do not expect to use Sonos integration and would rather decide among premium headphones based on your own fit and listening preferences.
Verdict
The Sonos Ace Ultra gives Bose real competition in the sense that it is a credible, much-improved premium alternative—not in the stronger sense that it has been proven to beat Bose QuietComfort Ultra Headphones (2nd Gen). Reviews report better sound and refinement than the original Ace, and Sonos system linking gives the Ultra a distinctive reason to appeal to Sonos households. At $449 on Sonos’s US listing, it is most compelling when those system features matter to you; the evidence here does not justify calling it the overall ANC winner.
