The Sonos Ace Ultra wireless headphones have landed, and it looks like good news throughout, with Sonos promising a "direct connection to the Sonos system."
Positioned above the three-star Ace – the brand's first headphones released in 2024 – the new step-up Ace Ultra have been designed from the ground up to deliver the improvements to sound, noise-cancelling and wider compatibility with the Sonos ecosystem that were missing from Sonos' debut over-ears.
At the heart of the Ace Ultra is the "Headphone Engine 2", a next-gen wi-fi hardware and software system that lets you link the headphones directly to your existing Sonos system. It's the feature that we (and Sonos customers) have wanted all along, allowing you to swap audio from any Sonos wireless speaker or soundbar to the Ace Ultra headphones at the press of a button (or via the app), and back again.
Listening to music on the Ace Ultra from your laptop or smartphone is still done via Bluetooth rather than wi-fi, but this is a marked improvement over the original Sonos Ace, where you could only 'swap' audio from select Sonos soundbars.
With the Ace Ultra, this 'headphone linking' feature will work with any current Sonos soundbar and wireless speaker under the Sonos 27 ecosystem, including the Arc Ultra, Ray, Beam (Gen 2), new Beam Ultra, Sonos Five, Era 100, Era 300, Move 2, Play and Roam 2.
The Ace Ultra feature all-new Sonos-designed 40mm drivers, and the sound is tuned with input from the Sonos Soundboard, which features leading figures in music and film (including Grammy winners) to deliver a sound "that stays true to the artist's intent."
Active noise cancellation has been given a boost, with the Ace Ultra promising to be twice as effective in this regard. The Ace Ultra house 10 mics (up from eight on the original Ace), with an adaptive ANC system that continuously monitors your surroundings to deliver the best ANC experience.
An Adaptive EQ also tunes the ANC to adjust to any imperfections in the acoustic seal around the earcups, such as gaps in the fit for those wearing glasses.
An Aware mode, which lets outside sounds in, also returns, as does support for headtracking with Dolby Atmos content.
Battery is up to 35 hours (up from 30 hours from the original Ace) with ANC activated, and you can get three hours from a fast-charge of three minutes. The higher-quality aptX Lossless codec is supported, while native support for 16-bit/48kHz resolution is once again supported via a wired USB-C connection.
The general design of the Sonos Ace Ultra remains the same as before, with soft foam cushions to provide maximum comfort, and physical buttons that include a multi-function button/slider (called the 'control key') through which you can adjust volume, change noise modes and playback, and send music to and from your connected Sonos speakers via the 'headphone linking' feature.
There are three-band and eight-band EQ settings in the app to further customise the sound to your tastes, whereas TrueCinema technology tunes the headphones' sound according to your room's acoustics when connected to a compatible Sonos soundbar.
The Sonos Ace Ultra headphones will cost £399 / $449 and be available globally from 29th September, with pre-orders starting from today, 1st September. The headphones will be available in four finishes: new sand and agave colours, as well as the standard black and white options.
Interestingly, the established Sonos Ace will continue to be available. The Ace are currently priced at £299 / $299 / AU$449, which is a considerable drop from their launch price of £449 / $449 / AU$699. Those in the UK will also get a bonus saving, as the new Ace Ultra will launch for £50 less than the inaugural Ace did.
We have high hopes for the new Sonos Ace Ultra headphones, which seem to address many of the issues we had with the original Ace – such as incomplete features, buggy connections, "average" sound, and ANC quality that didn't compete with strong rivals.
Let's see if they give the current Sony, Bose and Sennheiser class leaders a run for their money.
