Also consider How I tested Sonos Ace Ultra: two-minute reviewSonos is making a real statement of intent with its new wireless headphones, the Sonos Ace Ultra.The multi-room master has made a whole host of improvements to this upgraded wireless over-ear model, which has arrived two years after the original Ace came to market. The Sonos Ace Ultra have enhanced custom 40mm drivers, a new headphone engine, better battery life, better noise-cancelling, and more detailed EQ to name a few things. So can they finally compete with flagship rivals from the likes of Sony and Bose to become some of the best noise-cancelling headphones we've tested? Here’s what I think after weeks of testing.Let’s start by addressing the most important area of all: sound quality. We felt that the original Ace fell short of the best headphones around due to one main issue: their middling musicality. But the Ace Ultra have remedied that, and then some.Latest Videos FromTechRadarWhen listening to the Sonos Ace Ultra beside the original model, the differences were stark. Where the standard Sonos Ace sounded confined, overstretched, and unrefined, the Ace Ultra offered openness, intricate detailing, and a broader, more organized soundstage. What’s more, they provide better balance across the frequency range, with deep yet controlled bass, rich but less overzealous mids, and tight, articulate treble.While I still consider some similarly priced competitors, like the Sony WH-1000XM6 and Bowers & Wilkins Px7 S3 to supply slightly more premium, detailed sound (for music, that is), the Ace Ultra are really not far behind. Sonos listened to the critics, and proved that it's up to the task of going toe-to-toe with the titans of the headphone world.We already loved the original Ace for movies, though, finding that they offered immersive Dolby Atmos audio with effective head-tracking to boot. And that’s much the same on the Ace Ultra. They whip up wonderful width, strong command over height effects, and never neglect the fundamentals like clear dialogue and cinematic, pounding bass.But what’s new on the Ace Ultra? Although music got a seismic upgrade, other alterations feel a bit more incremental — but that’s by no means a bad thing. Two more microphones have been added to the Ultra, bringing the total to ten, and ANC is great here. Wherever I was, my soundings were subdued to great effect, almost creating a bubble of silence. ANC is adaptive this time around and adjusts nicely, and the transparency mode works a treat. Call quality is strong too, as you may expect.Get daily insight, inspiration and deals in your inboxSign up for breaking news, reviews, opinion, top tech deals, and more.Battery life has also seen a boost, and you’ll now get up to 35 hours with ANC on. Is this anything groundbreaking? No. But it’s slightly above the 30-hour standard for headphones in this price bracket, and I never felt that I had to charge these cans very regularly. The battery is also replaceable, and a rapid charging mode means you can get three hours of playback if you spend three minutes juicing them up.EQ options have also been expanded beyond the basic two-band equalizer found on the standard Ace headphones. There’s an eight-band option now as well as adaptive EQ, meaning you can genuinely tailor sound to your specific tastes.We also need to talk about the Wi-Fi capabilities of the Sonos Ace Ultra. No, we’re still not at the point where we can directly stream tunes over a local internet connection, but there are some nifty features at play. First of all, TV Audio Swap is back, enabling you to link the headphones to a compatible Sonos soundbar, and transfer sound seamlessly. This is highly responsive and effective, and while I didn’t find myself using this feature a ton, you can avoid the latency issues you’d get from connecting headphones to your TV over Bluetooth.The Ace Ultra also add Headphone Linking, though, which means you can also transfer sound from compatible speakers, like the Sonos Play, for instance. This is equally reliable as TV Audio Swap, and is a great option if you’re listening to music at home but want to keep listening without distracting others.It’s clear to see that the Sonos Ace Ultra don’t look very different from the previous model, but that’s no bad thing. They’re sleek, well-built, and offer a neat combination of comfort and over-ear security. They’re not fully foldable, and the included case could be better quality-wise, but these are fairly minor pain points in the grand scheme of things.Considering that the Ace Ultra cost the same as the original Ace at the point of launch — and actually less in the UK — they feel like a much more worthwhile investment. They’re by no means cheap, but their enhancements are meaningful and substantial, making these a great pair of headphones whether you have a pre-existing Sonos system or not. As a result, these are a great pair of headphones for music and movie lovers alike that feel worth the outlay — and are easy to recommend if you want a great all-round pair of premium wireless headphones.

The new model is priced at $449 / £399 / AU$699, which is the same as the standard Ace cost at launch in the US and Australia, though they’re actually cheaper in the UK than the original Ace were at the point of release.Given their price, the Ace Ultra have some extremely hot competition. For example, the Sony WH-1000XM6 are similarly priced, and offer an incredible mix of balanced, dynamic, and impactful sound alongside some of the best noise-cancelling on the market and a giant suite of features. Other competitors include the noise-crushing Bose QuietComfort Ultra Headphones Gen 2, the spacious sounding Bowers & Wilkins Px7 S3, and the ultra-detailed Sennheiser HDB 630.Sonos Ace Ultra review: specs Swipe to scroll horizontally Drivers Next-gen 40mm custom Active noise cancellation Yes Battery life 35 hours (ANC on) Weight 0.7lbs / 322g Connectivity Bluetooth 6.0, USB-C Frequency range 20Hz-20kHz (Image credit: Future)Sonos Ace Ultra review: featuresExcellent ANC with adaptive mode and effective transparency optionHigher-res audio available as well as Dolby Atmos for spatial soundTV Audio Swap and Headphone Linking works very wellThe Sonos Ace Ultra boast an excellent suite of features and are a highly personalizable, smart set of headphones.Let’s kick off with ANC, which has had quite the revamp. Now, you can toggle on an adaptive mode, which adjusts for things like fit, whether you’re wearing glasses, and if you make sudden head movements. But that’s not all.Sonos has also boosted the number of mics for the Ultra, with ten to the original Ace’s eight. The mics can monitor your surroundings and cut out external noise in real time, and they do this to great effect. Yes, the Ace Ultra supply great ANC, and no matter my environment, I was treated to satisfying, distraction-free listening.When out on walks, the sounds of cars passing by were totally nullified. When typing away in the office, the clacking of keyboards was fully subdued, and when travelling on public transport, engine sounds and surrounding chatter were put right to the sword. The Aware Mode is also very effective, and makes it incredibly easy to tune into your surroundings, with the new Voice Boost mode able to improve the clarity of voices around you if you toggle it on.The upgraded microphone system also helps the Ace Ultra to handle phone calls with greater care than ever before. When taking calls when out and about, my speech was perfectly comprehensible, and never sounded obscured by background noise, even when walking in a busy part of my city.Something else that’s received a boost is battery life. Sonos says that the Ace Ultra are capable of staying alive for 35 hours on a single charge, and my testing found this to be pretty accurate. This is a slight improvement on the original Ace, which could deliver 30 hours of use, which is essentially the standard for headphones in this price category. There’s also a rapid charging option, which gives the Ace Ultra three hours of playback from a three minute charge and a power saving mode if you want to extend the headphones’ life in a pinch.One of the more welcome additions to the Ace Ultra is their expanded EQ options. Now, you can make use of an eight-band equalizer to customize the sound of the headphones to your specific taste. This is a big improvement on the basic two-band equalizer on the original Ace (for bass and treble levels), though there’s a more basic three-band option on the Ace Ultra if you prefer a less detail-oriented approach.Let’s stick with sound, because there are a number of great features here that help you get the best out of both music and movies. First of all, you get all the hi-res goodness from the original Ace, with aptX codec support, as well as lossless audio via USB-C — and there’s a USB-C to 3.5mm cable bundled if you want to use them with a laptop, DJ controller, or other source device.Dolby Atmos also returns on the Ace Ultra, enabling you to enjoy spatial audio on the go. Once again, this works an absolute treat — especially for movies, where head-tracking also helps to further immerse you in on-screen action. I tried using the TV Audio Swap feature, which enabled me to connect the headphones to the Sonos Beam Ultra, and Atmos movies sounded wonderful — more on that in the ‘sound quality’ section.While the situations in which I’d use TV Audio Swap are admittedly niche, it's a very reliable feature. It harnesses Wi-Fi connectivity, so you don’t have to deal with the latency issues that connecting headphones to your TV over Bluetooth would bring. And you can easily switch between the soundbar, headphones, and other compatible Sonos speakers with a simple press of a button, which is highly convenient.The Ace Ultra’s new Headphone Engine 2 also enables Headphone Linking, which allows them to directly connect to other components in your Sonos system — including compatible speakers such as the Sonos play — and move audio to and from your speakers and headphones. Like TV Audio Swap, this feels seamless and speedy to activate, and is great if you’re blasting music at home, but don’t want to disturb others if they want some peace and quiet.On top of all of this, you get the usual good stuff: multi-point pairing, Bluetooth 6.0 connectivity, wear detection, and a relatively intuitive companion app. And when you add all of this together, I think it's fair to say that the Ace Ultra offer an incredibly fleshed-out, and well-refined feature set.Features score: 5/5 (Image credit: Future)Sonos Ace Ultra review: sound qualityBig improvement over original Ace with better soundstaging, detailing, and controlDeep, immersive bass, clean mids, and tight, expressive trebleFantastic Dolby Atmos performanceWhile we considered the original Sonos Ace to be a good pair of headphones, their somewhat middling musicality ended up holding them back from greatness. But luckily, Sonos has listened to the criticism, implemented next-gen 40mm custom drivers, and remedied a lot of the issues we had with the previous model. The result? A genuinely great-sounding pair of headphones.I tried comparing the Sonos Ace Ultra against the original model directly, and when I say that the difference is striking, I truly mean it. In essence, the Ace Ultra provide a significantly broader soundstage with far better organization and balance, as well as deeper, more controlled bass, and more articulate, detailed treble. I also found them to offer superior handling of dynamics and enhanced instrument separation, meaning that, for me, Sonos is closer to rivals like Bose and Sony than ever before.Sonos has been keen to talk up the Ace Ultra’s improved bass, so I started out by listening to a house track, Get It On by Jansons. The Ace Ultra delivered palpable, pumping bass, that was rhythmic and rapid, never sounding lethargic or boomy. This never concealed other sounds across the frequency range, either, with synths in the mid-range sounding well defined and tonally accurate, and high-pitched drums coming through with precision and vigor, helping the track to maintain its high energy.Treble was especially tighter on the Ace Ultra compared to the original model, and the wider soundstage gave each individual element more room to breathe, and this became a theme across all of my listening tests.For instance, with the funk track Joía Rara by Brylho, the upgrade the Ultra provided was considerable. On the original Sonos Ace, the soundstage felt confined, with guitars lacking definition in the mix, and as the track built, the horns, bass, vocals, and guitars sounded slightly convoluted, resulting in a messier presentation than I’d expected. But on the Ace Ultra, things were totally different. Guitars in the intro occupied a unique pocket, bass was well-balanced, and finer percussive details were perfectly audible. Vocals were also separated to greater effect, and while they weren’t the most textured or forward, they were more than clear enough.Are the Sonos Ace Ultra the best-sounding headphones in their price bracket? Well, they’re not far behind the competition, though I do still think a couple of models edge just ahead. For example, I tested them side by side with the Sony WH-1000XM6, and I found that Sony’s cans supplied a slightly more dynamic low-end output and detailing in the mid-range. It was very close between these two, though. Of course, if you want the most expansive soundstage, headphones like the AirPods Max 2 will edge out the Ace Ultra, but they’re slightly more expensive.Before we move onto design, we have to talk about the Ace Ultra’s handling of spatial audio. They support Dolby Atmos as well as head tracking, really helping you to immerse yourself in your favorite movies and TV shows, and the expansiveness that the headphones supply is seriously impressive.When using TV Audio Swap with some 4K UHD Blu-ray discs, the Ace Ultra were able to conjure up an excellent sense of width, almost like some of the best Dolby Atmos soundbars can. I started by watching Elio, and the Ace Ultra did an incredible job — voices were clear, and as characters moved across the screen, they were tracked with precision, and if I tilted my head, sound shifted dynamically as if I was speaking with characters directly. As Elio returned to earth, deep, pounding bass hit with immense power too, but didn’t sound muddy or overbearing.With Godzilla Minus One, the sense of a plane flying overhead in the opening scene was captured far more effectively than expected. It was genuinely convincing, as if the sound was truly coming from above. Dialogue was clear again, and Godzilla’s almighty screech was both tonally accurate and controlled, rather than tinny. More generally, the movie’s action scenes had tremendous width, creating a genuinely immersive experience.Sound quality score: 4.5/5 (Image credit: Future)Beautiful design, and very well madeComfortable yet secure fitNot fully foldable, but case included for added securityThe Ace Ultra look an awful lot like the original Ace, but as someone who loved the way those headphones looked, that’s a big plus. The ear cups are relatively flat and understated, the rounded look is sleek and sexy, and the metallic details only add to the sense of premium. The button controls have shifted about slightly, but they’re incredibly easy to reach, and are all very responsive.I tried the Soft White version which is stylish and modern, but the Ace Ultra are also available in Black, Agave, and Sand. All of these colorways are minimalistic and suit the luxurious vibe of the headphones to perfection.In terms of fit, the Ace Ultra strike a really strong balance between comfort and security — they’re the goldilocks of headphones, if you will. There’s enough clamping power to prevent excess sound seeping in and keep them on your head during a workout or similar, but I never found this to be overbearing. Even when I was wearing a hat, the Ace Ultra felt really snug, with the plush ear cups and padded headband helping me to enjoy my music for many hours on end.One subtle thing I like is how the inside of the right ear cup is green, making it easy to know which side is which when throwing the cans on. The right cup also features a slider, which can be used to easily adjust volume or trigger the Audio Swap feature. I usually prefer touch controls, but the tactile and reliable nature of these buttons might just have converted me.Something that may frustrated a few users is that the Ace Ultra are not foldable. Yes, the ear cups rotate flat for when you want to stow the headphones in the case, but rivals like the Sony WH-1000XM6 offer a more compact, travel-friendly design. In addition, the case itself doesn’t quite offer the quality I was expecting, with a fuzzy exterior that’s a bit prone to picking up fibers. I also found that the zip jammed a bit easily. I much prefer the magnetic case of the XM6, which is more seamless to use and has a more quality look and feel.Design score: 4.5/5 (Image credit: Future)Sonos Ace Ultra review: valueMore fully featured and better sounding than the original Ace……but for the same price (at the point of launch)A worthwhile choice for those with or without a pre-existing Sonos systemThe Sonos Ace Ultra cured the single ailment that plagued the original model above else: their middling musicality. When I tested both headphones side by side, the difference was night and day. The original Ace were held back by a limited soundstage, underwhelming instrument separation, and a lack of balance across the frequency range. But the Ace Ultra sound so much more open, organized, and detailed, and truly compete with flagship rivals from Sony and Bose.On top of that, you’re getting excellent Dolby Atmos performance, Headphone Linking and TV Audio Swap for linking up to other Sonos products, a beautiful design, and strong noise-cancelling capabilities. Considering that the Sonos Ace Ultra cost the same as the original model did at the point of launch — and less than the standard Ace initially cost in the UK — that’s pretty impressive.At $449 / £399 / AU$699, they’re still quite the investment, of course. And I do think that some rivals, including the Sony WH-1000XM6 and Bowers & Wilkins Px7 S3 just edge above them in terms of sound quality. But those models can’t compete when it comes to movies — a big selling point of the Ace headphones. And the interactivity that these have with other Sonos products makes them a slam-dunk for owners of products like the Sonos Beam Ultra and Sonos Play.Even if you don’t have a Sonos system, these headphones still justify their price with great all-round performance, a delicious design, higher-res audio codecs and wired lossless sound, as well as solid battery life. All in all, then, the Ace Ultra feel like a much more worthwhile investment than the original Ace, and manage to earn their price.Value score: 4.5/5 (Image credit: Future)Should I buy the Sonos Ace Ultra?

To start with, I sifted through the TechRadar testing playlist, but I also listened to a wide variety of tracks from my personal library. On top of this, I compared the Sonos Ace Ultra to some of their major competitors, like the Sony WH-1000XM6, as well as the original Sonos Ace.More generally, I’ve spent years testing gadgets here at TechRadar, where I serve as a Senior Reviews Writer. I’ve tested a wide range of audio gear, including other premium headphones like the Sony 1000X The Collexion, party speakers like the Marshall Bromley 750, Dolby Atmos soundbars like the JBL Bar 1300MK2, and more.Read TechRadar’s reviews guaranteeFirst reviewed: September 2026 Harry is a Senior Reviews Writer for TechRadar.
