alt Hacker NewsExcept for the "headphone" versus "headset" mode dichotomy that is inherent to Bluetooth, all those other issues are due to stupid product decisions that most OSes do to themselves independently on the same way.
If you use Linux + KDE, you can still use any microphone or headphone, many at the same time, or in whatever mode you want.
Linux + KDE user here.
It used to work on kde/plasma 5 at some point. And after a minor version update it stopped working.
Now the mic of my headset doesn't work because KDE insists that only the high quality sound output without mic is available. The mic + low quality output is gone from the settings.
Lucky for me this update also brought proper handling of the stereo positioned noise cancelling microphones on my thinkpad. So now I can actually enjoy the luxury of built-in microphones that work. Until the day it wont I guess.
