Sonos, a leader in home audio, has just rolled out a substantial free over-the-air software update for its flagship over-ear headphones, the Sonos Ace. Starting June 10, 2025, this update introduces a host of breakthrough features aimed at enhancing both personal and shared entertainment experiences. The Sonos Ace, which marked the company’s debut in the headphone space back in 2024, is now more capable than ever. These new tools focus on immersive sound, personalized audio calibration, and smarter, more intuitive listening.
Key Takeaways:
- Sonos Ace headphones receive a major free software update as of June 10, 2025.
- The update adds “Personal Home Theater for Two,” enabling two users to wirelessly share TV audio via a Sonos Arc.
- “TrueCinema Spatial Audio” calibrates surround sound to match your room layout.
- Adaptive Noise Cancellation now adjusts automatically for variables like glasses or hair.
- Phone calls get clearer with “SideTone” for more natural conversations.
Unlocking Shared Experiences: “Personal Home Theater for Two”
Among the most buzzed-about features in this update is “Personal Home Theater for Two.” For the first time, two people using Sonos Ace headphones can wirelessly listen to TV audio from a Sonos Arc soundbar at the same time, thanks to TV Audio Swap. That means couples, roommates—or anyone who doesn’t want to disturb others—can enjoy a late-night movie or binge-watch a series together, with full surround sound, all through their own headphones.
It’s an upgrade that feels small on paper but massive in real-world impact. The process is simple enough: one user initiates TV Audio Swap, and the second Ace pairs shortly after. Both sets of headphones then receive a low-latency, high-fidelity feed from the Arc. No external speaker adjustments, no disturbing background noise—just shared entertainment, neatly personalized.
Hyper-Realistic Sound: The Power of TrueCinema Spatial Audio
The new TrueCinema feature might just be the most ambitious update here. It’s not just about hearing sound around you—it’s about hearing sound as if it’s actually happening in your room. This system calibrates the spatial audio to match your specific environment, using the room’s natural acoustics to replicate a genuine surround sound setup.
Traditional spatial audio often feels a bit generic, like a one-size-fits-all version of 3D sound. TrueCinema flips that. By accounting for how sound would realistically reflect and travel in your space, it creates a more grounded, believable soundstage. You’re not just immersed; you’re positioned right in the middle of the action, whether you’re watching a blockbuster, gaming, or streaming a show. It’s the kind of fine-tuned realism that might make you forget you’re wearing headphones at all.
Smarter Listening: Adaptive Noise Cancellation Evolved
Noise cancellation isn’t new. But making it adaptive enough to account for daily variables—like whether you’re wearing glasses, or how your hair sits under the headphones—is a thoughtful evolution. The updated Adaptive Noise Cancellation feature monitors sound leaks and adjusts in real time, even as your environment or fit changes.
That might sound overly technical, but the takeaway is pretty practical. If you’ve ever worn headphones with glasses and felt the noise canceling wasn’t quite right, this upgrade addresses that exact issue. The headphones constantly optimize how they seal against your head, ensuring consistent noise reduction no matter what you’re wearing—or how you’re wearing them.
Clearer Conversations: Smoother, More Natural Calls with SideTone
It’s not just the entertainment side that’s getting a boost. Phone calls, too, are now more natural, thanks to SideTone. This feature allows you to hear your own voice during a call, making conversations feel more balanced and intuitive—especially when the noise cancellation is fully cranked up.
Without something like SideTone, users often find themselves speaking louder than necessary, almost shouting into a void because they can’t hear themselves. Now, your own voice is subtly fed back into your ears, restoring that natural cadence and making longer calls feel a lot less draining. And with overall improved voice clarity, both sides of the conversation benefit.
The Future of Sonos Ace: A Powerful Statement
When Sonos launched the Ace in 2024, it was stepping into a crowded, competitive space. But this software update—rolled out less than a year later—sends a clear message: Sonos is serious about redefining what headphones can be. It’s not just hardware that matters anymore. Ongoing software innovation plays just as critical a role in shaping user experience.
The update is available to all Sonos Ace users globally starting June 10, 2025. It’s completely free, delivered wirelessly, and instantly expands what your headphones are capable of. For current owners, it’s essentially like waking up to a new device overnight—no new purchase necessary.
This kind of post-purchase enhancement isn’t just convenient; it’s strategic. It reinforces Sonos’s broader philosophy: that the value of your gear shouldn’t be frozen in time. Instead, it should evolve with you. In an age where tech can feel outdated fast, that’s a refreshing approach—and one that could set a new standard for premium audio gear going forward.
