Sonos Ace Review (2024)

The Ace looks and feels like a modern Sonos product: clean matte plastics, subtle metal accents, and restrained color options (Soft White and Black) that match their speakers. The earcups pivot smoothly, the yokes feel sturdy, and the case is slim and nicely finished, making it easy to travel with. Materials don't quite reach the luxury feel of B&W Px8 S2 or B&O H100, but they're clearly above typical midrange builds. Buttons and sliders feel positive, and the fit-and-finish is tight, with no rattles or creaks reported in longer-term reviews. It's premium without being ostentatious — very 'Sonos' in that sense.

Despite being heavier than many competitors on paper, most long-term reviewers rate the Ace as very comfortable. The pads are soft and deep enough to avoid ear contact, the clamp is moderate, and the headband padding spreads weight well across the top of the head. People who usually struggle with heavy wireless cans often note they can wear the Ace for multi-hour sessions without hotspots. It's not quite 'disappears on your head' light, but as a travel and TV headphone it clears the comfort bar easily for most users.

Sonos clearly tuned the Ace for cinematic impact rather than studio neutrality. There's a strong sub-bass bump and an upper-bass lift, with mid-bass comparatively suppressed, making the low end feel powerful but uneven. Explosions, LFE rumbles, and movie scores sound big and satisfying, which works well for TV and films, but for music it can feel oddly shaped — kick drums sometimes lack punch while sub-bass hums along underneath. There is also measurable bleed from upper-bass into the lower mids, which contributes to a slightly thick, foggy character on some tracks. It's fun in a 'home theater' sense, but not particularly accurate or tight if you're used to cleaner, more linear bass.

The midrange is the weakest part of the tuning. Multiple critical reviews note a recessed midrange with upper-bass/lower-mid bleed, which pushes vocals and instruments slightly back in the mix and robs them of presence and clarity. Dialogue in movies can still be intelligible thanks to overall tuning and spatial tricks, but for music — especially vocal-centric or acoustic material — the Ace struggles to sound natural. This is compounded by the limited onboard tuning tools: you get simple bass/treble sliders rather than a full parametric EQ, so rescuing the mids inside the Sonos ecosystem is difficult without third-party hacks. For a music-focused listener, this midrange tuning is a significant downside.

Treble is a mixed bag: there's a notable peak that gives the Ace some 'detail' and bite, but it's not particularly refined. Some reviewers call out a slightly harsh or fatiguing quality on sibilant vocals or certain sound effects, especially at higher volumes, while finer micro-detail and resolution lag behind class-leading headphones. For movies, that extra top-end energy can help with clarity and effects; for music, it often lands in a 'bright but not especially resolving' zone that doesn't satisfy analytic listening. With only basic EQ, toning down that peak without dulling everything else is hard to do.

Where the Ace redeems itself for many users is spatial presentation. Several reviewers highlight an expansive, 'outside-the-head' stage with a cinematic sense of space, especially when using TV Audio Swap with a Sonos Arc and Dolby Atmos content. Dynamic head-tracking and spatial audio contribute to a convincing surround impression that outperforms many competing ANC headphones for movie and TV immersion. For stereo music, the stage is still good — wide and reasonably deep — but the tuning and midrange softness limit how precise imaging feels compared to more audiophile-focused models. It's very good by travel-headphone standards, especially for video content, but not class-leading for critical stereo listening.

Features and ecosystem are where the Ace earns its keep: strong ANC performance that can reduce ambient noise by ~90% in some tests, 30-hour battery with ANC, plus 3-minute quick charge for ~3 hours of use. Bluetooth 5.4 with multipoint, aptX Lossless/Adaptive for compatible Android devices, and wired USB-C or analog connections. TV Audio Swap provides seamless switching of TV audio between a Sonos soundbar and the Ace via long-press on the earcup. On the downside, the headphones don't behave like a standard 'Sonos room' in the multiroom audio interface, and integration feels more bolted-on than deeply unified. There's also no true passive mode — if the battery is dead, you're done until you charge.

At $449, the Ace sits in direct competition with Sony's XM6, Bose QC Ultra, and Sennheiser's Momentum line. If you already own a Sonos soundbar and care a lot about silent late-night TV watching with Atmos and head-tracking, the value proposition is solid: you're paying for a unique integration that others don't match. If you're mainly buying a music headphone, value is weaker. For the same money, you can get better sound and tuning from competitors, and more advanced EQ in something like Sennheiser's HDB 630. The Ace becomes a 'nice to have' luxury more than a best-in-class choice unless the Sonos ecosystem features are central to your use case.

The Sonos Ace is a great first attempt at over-ears: comfortable, nicely built, and genuinely impressive for movies and TV — especially if you already own a Sonos soundbar. As a music headphone, though, the tuning feels like a missed opportunity: big bass, recessed mids, and peaky treble with limited EQ make it hard to recommend over similarly priced rivals if you actually care about fidelity. Buy it for the ecosystem and TV features, not for reference-grade sound.
