Sonos Ace automatically changes to Off Mode and loses system chimes.

Hi everyone,

I’ve been using Sonos Ace headphones since January 2025, and I’ve loved them. My original pair worked perfectly fine, but the leather on the headband started peeling, so Sonos ended up replacing the entire unit.

The replacement headphones would randomly switch the Noise Control mode to Off, and all the system chimes would disappear. No feedback chimes when changing volume, Bluetooth connect/disconnect, switching noise modes, or powering on/off. The headphones themselves are still on, just stuck behaving like this. The chimes eventually come back, but completely randomly.

I contacted Sonos and managed to get them replaced again, but the new pair is doing the exact same thing.

I'm starting to think this might be a software issue. I'm wondering if my original pair was just running older firmware and that's why I never had this problem before.

Anyone else dealing with this?

I have never experienced this on my Ace.

Once you connect the Ace it should show in the Sonos app when updates are available.

    I know how to check for updates, but I was more wondering whether my original pair might have been running an older firmware version, as I never experienced this issue with them.

    Both replacement pairs have been up to date (build 3.9.9-01c251022). I've experienced the issue in different environments and across multiple devices. I also tried using multipoint both on and off to see if that might be causing it, but the issue still happens.

    I like the Ace overall, so it's just a bit annoying when this happens every so often. I'm mainly curious if anyone else has been experiencing this recently, particularly after updating their headphones.
