Hi,
Thank you for the answers. I should have been more precise; currently I have WH-1000XM4 and the issues I am having (as these happen not every single time and not always):
- when I switch on the headset, I need to go to bluetooth on the PC or laptop and click manually "connect" - it won't connect by itself
- I keep my PC open for days. So for example I listened to youtube in 3 separate tabs. They are all stopped and it could be that were stopped 3 or 4 days ago, but also 10 minutes ago. All are stopped. I get a call on Teams. Or just sit with the headset on because I need to be in a quiet around. Then I remove the headset and push the switch off button - at this moment one of the stopped youtubes starts playing. It's a nonsense, especially when I am connected remotely to the office so I need to switch back to the local PC and try to find which tab is making noise :-)
I tried to google this a few times, but it seems nobody has such problems and all I can find is that, like you mention, that when they get a call it doesn't STOP the youtube. My issue is that switching off the headset STARTs a video....

I'm not sure I understand the question.

Anyway: I did a test and if, for example, you have a video on the computer and you receive a call on the phone it will cut the video then resume it when you've hung up, on the other hand with me, disconnecting the headset doesn't restart a Youtube video.

I hope that helps!
Have a great day!

I tested it briefly and it didn't work. But I am of the opinion that you can adjust it.
