I am currently experiencing an unbelievably annoying bug where once I finish on Google Meet in Firefox, all audio/video across the whole OS plays in slo-mo. I have to turn my headphones off and back on to fix it.
It's something specific to these headphones (Sony WH-C700N), as they do something different to get higher audio quality when using the microphone. Apple have helpefully removed Bluetooth Explorer from Xcode and the debug panel from the Bluetooth status bar icon, so I'm yet to figure out what mode it's using that my other headphones (Sony MDR-ZX770BN) don't.
