The Sonos Ace Ultra arrives as the company’s second attempt at premium wireless headphones, following the original Sonos Ace launch in 2024. According to reviewers, the Ultra model represents a more refined effort that addresses weaknesses found in its predecessor while building on its strengths.
Among the most notable improvements is the integration of Headphone Linking. This feature allows users to seamlessly transfer audio playing on a compatible Sonos speaker or soundbar directly into the headphones. The handoff process is nearly instant, and the capability is described as a unique selling point for the Ace Ultra. This function utilizes the new Sonos 27 software platform, requiring owners of older Sonos hardware to upgrade for the best experience.
In terms of audio performance, the Ace Ultra has received meaningful upgrades. Sonos installed new 40mm drivers that incorporate a dual-ring magnet motor structure. This design is intended to reduce distortion and deliver a clearer, more detailed sound with a punchier bass response.
Noise cancellation has also been significantly boosted. Sonos claims the Ultra offers up to twice the ANC performance of the original model. This enhancement comes from a new 10-microphone array, which detects and cancels environmental sounds like those found in airplane cabins or underground train cars. Multiple reviews noted that while the performance is a major improvement, it does not quite match the top tier set by Sony or Bose.
Battery life shows substantial gains, lasting up to 35 hours with Adaptive Noise Cancellation active. With ANC off, the endurance extends up to 50 hours. A quick charge of three minutes reportedly provides three hours of listening time. The lithium-ion battery unit remains user-replaceable, contributing to the product’s longevity.
Design remains largely consistent with the original Ace. It maintains a slim, classy profile, with the earcup design feeling comfortable for prolonged use. The headphones are not collapsible, but the earcups remain detachable, and the controls are physical, featuring a dedicated Content Key for playback and a Power/Bluetooth button on the left earcup.
The Ace Ultra also includes Adaptive EQ, a feature that measures the seal and fit of each earcup. It then adjusts the sound automatically to ensure optimal audio quality regardless of the user’s ear shape.
In the UK market, the Ace Ultra is priced at £399, which is £50 lower than the original Ace’s UK RRP of £449. This positions the headphones directly against the Sony WH-1000XM6, which launched at £400. Pre-orders are available starting September 1, 2026, with general availability set for September 29, 2026.
Other functions include robust call quality features, aided by ten microphones and beamforming vocal mics, designed to suppress background noise. Furthermore, the headphones support wired listening up to 16-bit/44.1kHz over a cable connection.
