Sonos Ace Wireless Headphones

The Ace is Sonos's debut in a category it has no business being a newcomer in, and the company has clearly decided to lead with hardware. A stainless steel headband, magnetically attached memory foam and vegan leather pads, physical buttons instead of finicky touch panels, and a genuinely well-thought-out hard case with its own internal cable clamshell — at 312g with flat-folding cups, this feels like a product designed by people who actually travel with headphones. Even the small stuff lands, like the mint-green right ear pad liner on the white model that tells you which way round to put them on without squinting at tiny L/R markings.

Spec-wise it covers the 2024 flagship checklist: 40mm angled drivers, Dolby Atmos with head tracking, aptX Lossless over Snapdragon Sound, and a claimed 30 hours. The obvious audience is existing Sonos owners, since the soundbar integration is the one thing no competitor can replicate. Everyone else is looking at a $449 pair of headphones that borrows its silhouette from the Sony WH-1000XM5 and its ambitions from the AirPods Max — and has to beat both, plus Bose, Sennheiser and Bowers & Wilkins, on merit alone.

This is where the story gets complicated, because the critical consensus is genuinely split. What Hi-Fi? called it a disappointing debut, flagging a lack of clarity and expression, stunted dynamics, buggy behaviour in testing and average call quality. SoundGuys landed at 7.4, happy with the build and battery but unimpressed by the default tuning, the ANC and a thin app feature set. RecordingNow was warmest at 8.7, though its enthusiasm came with two caveats that matter: bass that needs EQ to come alive, and a somewhat compressed soundstage — and an explicit note that the value case is strongest when discounted. Read those together and a picture emerges of headphones that are competent rather than special at a price that demands special.

Credit where it's due: Sonos kept working on them. The 3.9.7 firmware update in June 2025 improved ANC, features and microphone performance, which addresses several of the launch criticisms directly. That's a meaningful signal about long-term support. But it also means the Ace spent a year underdelivering on things a $449 headphone should have nailed on day one, and a firmware patch doesn't retune a driver.

The other nagging issues are structural. There's no IP rating at all, which is a strange omission at this price when the competition largely covers itself. Fit is a lottery — fine for glasses wearers thanks to moderate clamp, but tight if you have larger ears. And the headline ecosystem feature is exactly that: an ecosystem feature, worth real money to a Sonos household and worth nothing to anyone else.

I'd rate these a solid buy for existing Sonos owners and a considered maybe for everyone else, ideally at a discount. The hardware deserves better than the tuning it's wrapped around. One honest caveat on this assessment: the available information is strong on build, features and reviewer sentiment, but light on measured detail, so I'm weighting published critical consensus heavily here rather than claiming firsthand listening.
