Very choppy and pitched sound with bluetooth earbuds on current master

I have two headsets:

1. Bluedio T-Monitor, which is a typical bluetooth headset with bluetooth 5.0 internal module (i have bluetooth 4.1 adapter), they works fine, extremely rare choppy sound and works OK.
2. Mi True Wireless EBs Basic 2, with them i have a problem, it's a pair of earbuds, which connect to themselves to serve stereo.

For some reason, current master makes lots of choppy sounds and sometimes even blackouts while i play various sounds in system (tested on firefox and mpv). Quite often sounds even pitch. External factors like EM aren't affecting them, since it worked fine before.

In logs, i can see something like this, but it's not logging this every time it happens, quite rarely actually:

What could be the issue for this? Maybe incorrect quantums for really underpowered devices like earbuds with small antenna?
