Sonos has upgraded its over-ear headphones to an “Ultra” model, aiming to blend home audio integration with long battery life and immersive surround sound. After a week with the new Sonos Ace Ultra, I found a mix of thoughtful engineering and odd trade-offs. These headphones excel in some areas and underwhelm in others.
Look and feel: subtle styling with practical touches
The Ace Ultra keeps Sonos’ restrained aesthetic. The shape and finish are familiar, with new color choices that feel modern and muted. The unit I tested came in a soft green-blue that fits many interiors.

- Weight: lighter than some premium competitors, which helps for extended wear.
- Color cues: the inner cup shades differ to make left and right easy to spot.
- Included accessories: a semi-soft carrying case and two short cables — USB-C to USB-C for charging and USB-C to 3.5mm for wired audio.
The case is compact but not luxurious. The zipper feels fiddly. Overall, the Ace Ultra aims for comfort over flash. Padding is plush and replaceable via magnets, so wear and tear won’t be a permanent problem.
Controls, ports, and Sonos-specific tricks
Sonos kept controls simple but added a couple of meaningful buttons. One side powers and pairs via Bluetooth. The other toggles between noise-cancelling, ambient mode, and off.
There is also a multi-function volume key that doubles as a content transfer control. This button lets you hand audio back and forth between the headphones and compatible Sonos speakers. If you own a Sonos soundbar or speaker group, this feature is a core selling point.
- Charging: USB-C port.
- Wired listening: included USB-C to 3.5mm cable.
- Box contents: short charging cable, audio cable, and a slim case.
Sound quality: a surprising dependence on ANC
Sonos redesigned the drivers for the Ultra. In practice, the sonic result behaves oddly across modes.
With active noise cancellation or ambient mode enabled, the sound becomes full and bass-forward. Turn those modes off and the tone thins out. The change is dramatic. I could not restore body by tweaking the EQ in the app.
Because of that, I mainly listened with ANC engaged. In that configuration, the Ace Ultra delivers a satisfying low end and a warm character. It’s enjoyable for heavy rock and bass-forward playlists, though it loses some mid and high detail.
Wired vs wireless listening
Using a wired connection improves clarity and definition. On a cable, the Ace Ultra can outperform some higher-priced rivals in certain areas. That suggests the wireless codec handling needs work.
Sonos added support for lossless over Bluetooth via Qualcomm aptX, but ecosystem limits may prevent native use on Apple devices. For the best fidelity, a physical connection remains the simplest route.
Spatial audio and Atmos
The headphones really stand out with surround formats. Dolby Atmos content and spatial mixes create convincing three-dimensional placement.
I noticed sound shifting as I moved in the room while watching TV. On movies and live concert recordings, the effect felt immersive and precise. Apple Spatial Audio support is listed, but I could not reliably enable it on Apple Music during testing.
Features overview: a densely packed spec list
Sonos stuffed the Ace Ultra with many modern conveniences. Below are the notable capabilities.
- Active Noise Cancellation with an aware mode for environmental sounds.
- Dolby Atmos and support for spatial audio formats.
- Wi‑Fi integration that enables seamless handoff to Sonos speakers and soundbars.
- Lossless-capable Bluetooth via aptX for compatible devices.
- Ten microphones for voice pickup and call clarity.
Noise cancellation performance sits in the mid-to-high tier. Aware mode helps but doesn’t fully replace pausing audio when you need to hear conversations.
How the Sonos ecosystem affects the experience
The Ace Ultra becomes particularly useful inside a Sonos setup. You can route TV audio to the headphones, then switch it back to the room speakers.
That handoff can feel effortless when it works. But the Sonos app often governs these transitions. If the app hiccups, the handoff may stall.
App behavior and reliability
The Sonos app has improved since a troubled redesign, yet it still introduces friction. During testing, playback sometimes paused and failed to resume without manual intervention.
Navigation can be confusing at times, and I often resorted to native music apps to find content. When using Sonos-specific features, though, the app remains necessary.
Beam Ultra soundbar: how it pairs with the Ace Ultra
I also tried the new Beam Ultra alongside the Ace Ultra to test handoff and Atmos playback.
The Beam Ultra delivers a straightforward Dolby Atmos experience with upward-firing drivers. It creates convincing height cues in a typical living room setup.
- Connectivity is focused: HDMI eARC and USB-C line-in are primary inputs.
- Bluetooth 5.3, Wi‑Fi, and AirPlay 2 are supported.
- It integrates well with other Sonos speakers for multiroom setups.
For casual listeners, the Beam Ultra provides satisfying surround sound. Enthusiasts may want separate L/R satellites and a subwoofer for more depth.
Battery life, comfort, and calls
Sonos rates the Ace Ultra at 35 hours of battery life. In real-world use across several long sessions, I charged them once in a week. The claim holds up.
Comfort is a standout. The cups are plush and the headphones sit lightly on the head. They rank among the most comfortable over-ear options I’ve tried.
Call performance is solid. The multiple microphones capture speech clearly, and people on calls reported good voice quality. Noise suppression during calls worked well in typical home environments.
Price, positioning, and who might benefit most
At $449, the Ace Ultra sits in a competitive bracket. They offer many modern features, strong battery life, and tight Sonos integration.
- Great fit for people who already own Sonos speakers and soundbars.
- Good for long listening sessions thanks to comfort and battery life.
- Less ideal for listeners who prioritize audiophile-level clarity over a bass-forward signature.
The Ace Ultra’s unique selling point is the Sonos handoff and Wi‑Fi integration. If that ecosystem matters, the headphones add value beyond basic specs. If you care only about pure musical detail, other options at this price may deliver a clearer, more open sound.
