Liberty air 2 stuttering during calls

Hey everyone,
I have samsung galaxy s21+, with the most updated firmware and software (the earbuds are updated too).
I’m suffering from stuttering during calls.
The ‘non-master’ earbud stutters (whether if it’s L/R) and the sound bounces and go ‘back and forth’
I’ve tried to hard reset and reconnect BT; reset network settings; and some other suggestions that I’ve found- and all of these didn’t solve the problem.

Any suggestions?
