If they're connected to my android phone while also connected to any other device (dual connection is a feature they tout), they play a tick sound every minute like a terrible metronome.
I'm incredibly sympathetic to Apple deciding everything about bluetooth is hot garbage and building an alternative for audio.
Edit: Here's a post that explains the issue better than I can. https://www.reddit.com/r/sony/comments/fqf71z/wh1000xm3_can_...
I've had better luck in all operating systems with a stand-alone USB bluetooth audio dongle: https://www.amazon.com/gp/product/B089PYFLBN
It's not perfect, but the combination of "you can select the codec" and "the bluetooth stack is 100% out of the hands of the OS" gave me dramatically better results on almost every headset I tried.
