Premium wireless headphones have reached the point where good sound and active noise cancellation are expected. The harder question is what you gain by spending $400 or more when excellent alternatives already exist.

That is the challenge facing the Sonos Ace Ultra. At $449, Sonos’s second-generation flagship headphones keep the original Ace’s US launch price while adding redesigned 40mm drivers, more microphones, Adaptive ANC, longer battery life, and a closer connection to Sonos speakers. Preorders are open now, with general availability scheduled for September 29, 2026.
Sonos has reworked the sound
Inside each ear cup is a redesigned Sonos-engineered 40mm driver. Sonos says the new acoustic system delivers greater detail, deeper bass, and lower distortion. Those are manufacturer claims, not conclusions we can make without listening to the headphones ourselves.
Independent reviews suggest the change is meaningful. TechRadar compared the Ace Ultra with the original Ace and found the new model more open and musical. Expert Reviews also reported a clear improvement, describing a warmer, fuller sound with more satisfying bass.
The headphones support spatial audio, Dolby Atmos, and dynamic head tracking when used with compatible content and devices. Lossless playback is available, but the connection matters: USB-C provides a wired option, while wireless lossless playback requires a supported device using Qualcomm aptX. It will not work over every Bluetooth connection.
Sonos has also expanded the sound controls. The Ace Ultra offers three-band and eight-band EQ adjustment, up from the original Ace’s simpler two-band controls. Adaptive EQ is designed to compensate for changes in fit caused by glasses, hair, and other gaps around the ear cups. That matters because a poor seal can change both the sound you hear and the amount of outside noise that gets in.
Ten microphones take on outside noise
The Ace Ultra uses 10 microphones, two more than the original Ace, alongside Adaptive Active Noise Cancellation that adjusts to the surroundings and the fit of the headphones.
Sonos claims up to twice the ANC performance of the original Ace at frequencies up to 65 Hz. That qualification is important: the figure refers to a limited low-frequency range, not a promise that every sound will be reduced twice as much.
Independent testing nevertheless points to an improvement. TechRadar found that the Ace Ultra effectively subdued traffic, keyboards, public-transport noise, and nearby conversation. Expert Reviews also found the noise cancellation substantially better than on the original Ace, although its reviewer still gave Sony and Apple the edge.
Aware Mode lets environmental sound through when you need to hear what is happening around you. The microphones handle calls, too. TechRadar reported clear speech in busy surroundings, while Expert Reviews found that the headphones reduced background noise without making voices sound overly processed.
Battery life reaches 35 hours
Sonos rates the Ace Ultra for up to 35 hours of listening with ANC enabled, five hours more than the original Ace’s stated 30-hour figure. TechRadar found that estimate reasonably representative in its testing. Sonos also says a three-minute charge from an empty battery can provide up to three hours of playback.
For long-term ownership, the replaceable parts are at least as interesting as the extra battery life. Sonos lists replacement Ace Ultra ear cushions for $39 and a replacement battery kit for $25. The battery is not a quick-swap part, though: replacing it requires disassembling the headphones and using tools. Sonos says the $25 kit is intended for people comfortable with that kind of work.
At 322g, these are relatively substantial over-ear headphones. Weight alone cannot tell you how they will feel during a long listening session, but Expert Reviews found them extremely comfortable in its testing.
The Sonos system is the differentiator
The Ace Ultra works as a conventional pair of Bluetooth headphones, so you do not need other Sonos equipment to use it. Sonos also includes USB-C-to-USB-C and USB-C-to-3.5mm cables for wired listening.
The more distinctive features appear when the headphones join a Sonos system. TV Audio lets you move sound from a compatible Sonos soundbar to the Ace Ultra for private listening. TechRadar tested the feature with the Beam Ultra and found the transfer reliable, including while watching Dolby Atmos movies.
Headphone Linking goes beyond TV sound, allowing audio to move between the Ace Ultra and compatible Sonos speakers. It is an appealing idea if you want to keep listening while moving between a room and your headphones, but it comes with limits. Sonos labels the feature Early Access and says it requires a compatible speaker, Wi-Fi, and setup through its app.
There are playback restrictions to consider as well. In Expert Reviews’ testing, Headphone Linking worked with music played through the Sonos app but did not transfer the AirPlay and Bluetooth sources the reviewer tried. It is better understood as an evolving Sonos ecosystem feature than as a universal way to move any audio source between speakers and headphones.
Who should buy the Sonos Ace Ultra?
The strongest case for the Ace Ultra is someone who wants premium noise-canceling headphones and already owns compatible Sonos equipment. The speaker and TV-audio features give these headphones a purpose beyond competing on sound and ANC alone.
The hardware improvements still matter if you do not own a Sonos system. Redesigned drivers, better noise cancellation, more EQ control, and up to 35 hours of battery life make this a more capable successor to the original Ace. Independent reviewers have also reported improvements in sound, ANC, and comfort rather than just changes on a specification sheet.

Where to Buy: Sonos
At $449, though, the Ace Ultra sits among strong premium-headphone alternatives. If you already own compatible Sonos speakers or a soundbar, it offers something most headphones cannot: a way to move listening between your home system and your headphones. If you do not, its sound, noise cancellation, comfort, and battery life are the features to weigh against rival models, not a reason to pay for Sonos integration you may never use.
