Drivers (other than your Bluetooth chipset) generally shouldn’t matter. AFAIK Bluetooth audio device protocol is generic.
How are you pairing the headphones? Are you adding your PC as a device using the Sound Connect App? I have different SONY earbuds, but they can pair with 2 different devices and switch between them with the app. Perhaps they still have another device (like a phone) selected for output?








The app runs on your phone (Android or iOS), and then you use the phone to manage Bluetooth connections for the earbuds. IMO you shouldn’t need a second device, but I guess they just assume 99% of people are connecting to a smartphone.
I think the issue is that the actual Bluetooth connection is obfuscated behind a proprietary connection to the app, and the app exposes the protocol.
I agree it’s a stupid implementation, prioritizing a UI for pairing over literally everything else, but you still might be able to get it to work. I’ve successfully paired my WF-1000XM4 earbuds with my EndeavourOS (KDE) desktop.
