This Sonos Ace review covers Sonos's first ever pair of over-ear headphones, a product that launched with sky-high expectations and a price tag to match. At £449 RRP, the Ace dropped into one of the most competitive categories in consumer tech, going head-to-head with the Sony WH-1000XM5, Bose QuietComfort Ultra, and Apple AirPods Max. After spending extended time with them, we can say with confidence that the Ace nails some things brilliantly and fumbles others. Here's where they land.

Cool Factor: 3/5

What are the Sonos Ace headphones?

The Sonos Ace are wireless over-ear headphones with active noise cancellation, Bluetooth 5.4, and support for spatial audio with Dolby Atmos. They launched in June 2024 at £449 and are available in Black and Soft White. They're Sonos's first foray into personal audio, and their standout feature is TV Audio Swap, which lets you seamlessly move sound from a compatible Sonos soundbar (Arc Ultra, Arc, Beam, or Ray) to the headphones at the press of a button.

Key specs include custom 40mm dynamic drivers, 30-hour battery life with ANC enabled, aptX Lossless support, Bluetooth Multipoint, wearer detection, and magnetic replaceable ear cushions. Charging is via USB-C, and a quick 3-minute top-up gives you around 3 hours of playback.

First impressions of the Sonos Ace

Unboxing the Ace is a premium experience. The minimalist packaging includes a solid carry case, USB-C cable, 3.5mm audio cable for wired listening, and a quick start guide. Everything about the presentation says "high-end" without overdoing it.

The build quality is immediately obvious. The stainless steel headband feels robust without being heavy, and the matte finish with subtle metallic accents looks genuinely stylish. A small but clever detail: the right ear cup has a contrasting inner colour (green on the white model) so you can tell left from right at a glance. It's a thoughtful touch that sums up the overall design approach.

The experience: comfort, controls, and sound

Comfort

This is where the Sonos Ace review gets enthusiastic. These are genuinely some of the most comfortable headphones you can buy. The memory foam ear cushions, wrapped in soft vegan leather, create a plush seal without excessive clamping pressure. The hinge-free headband distributes weight evenly, and Sonos clearly tested these on a wide range of head shapes, hairstyles, and accessories (including glasses, which is a welcome consideration). You can wear them for hours without fatigue.

For comparison, the Fairbuds XL take a different approach to premium comfort with their modular, repairable design. If sustainability matters as much as fit, they're worth a look alongside the Ace. We've also published a full Fairbuds XL review if you want to see how they compare in practice.

Controls

Sonos opted for physical controls rather than touch panels, and it's the right call. The Content Key is a slide-and-click mechanism that handles volume, playback, and calls. It's intuitive, responsive, and avoids the accidental touch inputs that plague some competitors. The dedicated Noise Control button switches between ANC and Aware mode with a single press. Simple and effective.

Sound quality

Here's where things get complicated. The Sonos Ace produce a balanced, clean sound profile. Highs are detailed, mids are present, and the bass is respectable without bleeding into the rest of the mix. For casual listening, podcasts, and film watching, they're more than competent.

However, compared to the best at this price, the sound can feel a little safe. There's a restraint to the dynamics that means tracks don't punch or breathe the way they do on the Sony WH-1000XM5 or Bose QC Ultra. The soundstage feels somewhat contained, and while individual frequencies are well-rendered, the overall presentation lacks the energy and expressiveness that makes you truly lose yourself in music. It's not bad by any stretch, but at £449 RRP, "not bad" isn't quite enough when the competition is this strong.

Where the Ace does shine sonically is with spatial audio and Dolby Atmos content. The head-tracked spatial audio is genuinely impressive for film and TV, and it's arguably the best implementation of its kind for movie watching with headphones. If you use these primarily for home cinema via a Sonos soundbar, the audio experience is excellent.

Noise cancellation

The ANC is solid but not class-leading. It handles steady low-frequency noise (train hum, air conditioning, engine drone) well, but it's less effective at cutting out voices and higher-pitched sounds compared to Bose's implementation. Aware mode works nicely, blending ambient sound with your content in a natural way. For commuting and office use, the noise cancellation is perfectly adequate, just not the best in the category.

TV Audio Swap: the killer feature

If you already own a Sonos soundbar, this feature alone might justify the purchase. Press the Content Key and your TV audio instantly transfers from the soundbar to the Ace. It's seamless, fast, and transforms late-night viewing. Pair two Sonos Ace headphones for shared watching, and you've got a genuine home cinema experience without disturbing anyone. The TrueCinema feature maps your room and renders virtual surround sound through the headphones, which is genuinely immersive. This is the Ace's unique selling point, and nothing else on the market does it this well.

Sonos Ace review: value for money

At the £449 RRP, the Sonos Ace are a tough sell for pure audio performance. The Sony WH-1000XM5 offer better sound quality at around £380, and the newer XM6 raises the bar further. The Bose QC Ultra match the Ace on price but deliver superior noise cancellation. The Apple AirPods Max are pricier but integrate seamlessly with the Apple ecosystem in the same way the Ace integrates with Sonos.

That said, the Ace have seen significant discounts since launch. Street prices regularly dip below £300, and they've been spotted as low as £189 during sales events. At those prices, the value equation shifts dramatically, and the Ace become a much more compelling option, particularly for anyone already invested in the Sonos ecosystem.

Another way to save is to pick up a pair refurbished through Back Market. You can often find the Sonos Ace at a significant discount compared to buying new, with a warranty and quality checks included. It's a smart route if you want the premium build without the premium price.

The verdict

The Sonos Ace are a strong first attempt at headphones from a company that knows audio. The design is beautiful, the comfort is best-in-class, the build quality is premium, and TV Audio Swap is a genuinely unique feature that no competitor can match. But the sound, while clean and pleasant, doesn't hit the heights of the Sony or Bose alternatives at this price, and the noise cancellation trails behind Bose's class-leading implementation.

Overall, a solid 3/5 Cool. The Sonos Ace look and feel fantastic, and the Sonos ecosystem integration is a genuine differentiator that earns them a place on the shortlist. But they didn't quite reach Stone cold because the core audio performance, the thing headphones exist for, doesn't lead the pack at this price point. If you're deep in the Sonos world and spot them on sale, they're well worth it. For everyone else, the Sony WH-1000XM5 or Bose QC Ultra remain the safer bets.

Sonos Ace review: FAQs

Are the Sonos Ace worth it in 2026?

At the full £449 RRP, they're a hard recommend when the Sony WH-1000XM5 and Bose QC Ultra offer stronger audio performance for similar or less money. However, the Ace regularly drop below £300 in sales, and at that price they become much more compelling, especially if you already own Sonos speakers or a Sonos soundbar. You can also save by picking up a refurbished pair through Back Market.

How do the Sonos Ace compare to the Sony WH-1000XM5?

The Sony WH-1000XM5 generally outperform the Sonos Ace on sound quality, delivering a more dynamic and detailed listening experience. The Ace win on build quality, comfort, and the TV Audio Swap feature. If pure sound matters most, the Sonys are the better pick. If you want premium design and Sonos integration, the Ace have the edge.

How do the Sonos Ace compare to the Fairbuds XL?

They're very different propositions. The Sonos Ace prioritise premium materials and Sonos ecosystem features, while the Fairbuds XL focus on sustainability and repairability with a modular design. The Ace sound slightly more refined, but the Fairbuds XL cost less and are built to last through user-replaceable parts. Read our full Fairbuds XL review for a detailed breakdown.

Do the Sonos Ace work without a Sonos soundbar?

Yes. The Ace connect via Bluetooth to any phone, tablet, or laptop like any other wireless headphones. The TV Audio Swap feature requires a compatible Sonos soundbar (Arc Ultra, Arc, Beam, or Ray), but it's not required for general use.

Are the Sonos Ace comfortable for glasses wearers?

Yes. Sonos specifically tested the Ace for comfort with glasses, earrings, and different hairstyles. The memory foam ear cushions are soft enough to accommodate glasses arms without creating pressure points, which is a notable advantage over some competing headphones.
