I’m having exactly the same issue on Windows 11 with my new pair of Nothing Headphones (1), and it’s incredibly frustrating.
I’ve tried all the standard troubleshooting steps: Removing and re-adding the device, manually connecting and disconnecting, restarting Bluetooth, etc. but nothing (pun intended) seems to fix it.
What makes it even more annoying is how random the issue feels. There’s no clear trigger: sometimes it happens after waking from sleep, sometimes seemingly out of nowhere. That said, it is consistent in one sense: at some point, the headphones always disconnect.
What’s particularly strange is that when this happens, I don’t hear the usual Nothing “unpairing” sound. The headphones seem to drop the connection silently, I only notice because the audio suddenly stops, and then I have to go into Bluetooth settings and manually reconnect them.
For context, this is happening on a brand-new Windows 11 machine (less than a month old), so it’s very unlikely to be caused by outdated hardware or a degraded Bluetooth adapter. Also the headphones work 100% fine and never gets disconnected on my Android phone or any other device I have tested them.
