EMBARRASSING! Unstable bluetooth headset connection

I tried to use a bluetooth headphone, but the sound quality is unstable, sometimes it's good but sometimes it's awful.

In addition, it may suddenly disconnect...I was studying in a library and suddenly the song started to play out of the speaker, and I wasn't aware of that until someone reminded me of it...

I guess there are several errors, here are outputs that may be helpful:
