Thank you for your reply.
It is a very weird Issue.
And my other Android Smartphone does not change the Mic and hearing Quality so bad like the Phone(1) is doing.
I know that the in general all Bluethoots In-Ears are changing in a low-quality mode when the microfon is used. But this quality during the ear(2) is so low that even my listeners are saying i should change and use my wired headset.
There has to be some issue with driver Settings.
I think the only test we can do is a hardwaresetting of the phone(1) and reinstall everyhting on a fresh phone.
