suddenly my macbook air (High Sierra OS) starts to have problems with my earphones bluetooth. After few minutes that I'm connected to my earphones, they start to make a scretch sound and after a while my macbook lose the connectivity with them. Sometimes happens that the laptop can't reproduce any sound with the earphones. I've already tried with another mac and the earphones works correctly, I have this problem just with my mac. I've already cancel my earphone from the bluetooth devices list and pair them again, but it didn't solve anything.

Anyone than can help me? Thank you very much! Cheers
