Having similar issues here. My call quality is very poor and sounds very choppy, almost like data is being lost over bluetooth. I have tried restoring back to facotry default with no improvement. Any additional help would be great.
If you have a free hand, I would recommend taking one out and using it as a regular microphone and speak into it. They use a contact microphone to pick up the sound, hence why it's not great, but if you use it like I suggest it comes through just fine.
I would be happy to look into your concerns.
