Better sound: A redesigned 40mm driver, Adaptive EQ, lossless audio and custom EQ aim to deliver richer, more detailed listening.
Stronger everyday performance: Ten microphones, upgraded ANC, Voice Boost and 35-hour battery life improve travel and daily use.
Sonos ecosystem advantage: Headphone Engine 2 enables direct audio swapping with compatible Sonos speakers and soundbars without relying on a phone.
The premium headphone race has a new contender at the top end. Sonos has unveiled the Ace Ultra at USD 449, with preorders open from September 1 and full sales set for September 29, 2026. The new model aims to fix the weak points of the first Sonos Ace while adding a feature that could make the biggest difference: a direct link with the Sonos home audio system.
The Ace Ultra keeps the over-ear design but brings major hardware changes. Sonos has built a new 40mm driver with a redesigned motor structure and an extra outer-ring magnet. The company says the new setup delivers deeper bass, clearer detail and zero distortion. Sonos also worked with Grammy- and Oscar-winning audio experts to shape the sound profile.
Sound quality sits at the heart of the Ace Ultra upgrade. The new driver aims for a wider and more detailed sound across bass, mids and treble. The headphone also supports lossless audio and advanced audio formats, including aptX Lossless. A custom EQ gives further control, with both three-band and eight-band options.
A more unusual feature comes from Adaptive EQ. Ace Ultra checks the seal around each ear cup and adjusts the sound to match the fit. That approach can help keep the audio balance stable when the fit changes during daily use. The idea gives the headphone a more consistent sound without a constant need for manual EQ changes.
Noise control gets one of the biggest upgrades. Ace Ultra uses 10 microphones, compared with eight on the original Ace. Sonos claims up to twice the Active Noise Cancellation (ANC) performance of the first model.
The new system checks outside sound and reacts in real time. Sonos says the extra microphones can help the headphones deal with difficult places such as underground trains and airplane cabins. The system also accounts for fit, which matters when glasses or small gaps around the ear cups reduce the seal.
Ace Ultra also gets an improved Aware Mode. A new Voice Boost feature can let important sounds through while the rest of the outside world stays quieter. That gives the headphone a clearer role for travel, office use and home use without a full switch to normal audio.
Battery life now reaches 35 hours with ANC on, up from 30 hours on the original Ace. That puts Ace Ultra closer to the long battery life expected from a premium wireless headphone.
Fast charging also remains a strong point. A three-minute charge can provide up to three hours of playback. A new power saver mode can extend the remaining battery life by turning off selected features. A full charge can take up to three hours with a USB-C connection.

The most important change may have little to do with sound quality. Ace Ultra introduces Headphone Engine 2, a new hardware platform that lets the headphone connect directly with a compatible Sonos system.
One press can move music, a movie or other audio from a Sonos speaker to Ace Ultra. Another press can send the sound back to the speaker. A phone does not need to sit between the headphones and the Sonos system for this feature. Headphone linking currently sits in Early Access, so Sonos can still change the feature before wider release.
TV Audio Swap also returns. The feature lets compatible Sonos soundbars send TV audio to Ace Ultra for private home theater use. TrueCinema adds room-based audio adjustment when Ace Ultra works with a compatible Sonos soundbar.

At USD 449, Ace Ultra enters a price range filled with strong options from Sony, Bose and Sennheiser. That makes the Sonos model a serious premium product rather than a simple follow-up to the original Ace.
The hardware now looks much stronger on paper, with a new 40mm driver, 10-microphone ANC, Adaptive EQ, 35-hour battery life, lossless audio and faster system access. Yet the biggest reason to choose Ace Ultra may remain the Sonos ecosystem. A buyer with several Sonos speakers can get a type of device-to-device audio control that rival headphones cannot match in the same way.
Ace Ultra therefore marks a clear shift for Sonos. The company is not only chasing better sound or stronger ANC. It is placing a premium headphone inside the same home audio system as its speakers and soundbars. At USD 449, that strategy gives Ace Ultra a distinct position in a crowded market, with the September 29 launch set to show whether the new hardware can match the promise on paper.
