Unusable bluetooth audio (AMD, BigSur)

So I used to own wireless earphones when I still had 4gen i5 on Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave with Clover, it worked perfectly well but they broke. Last summer I bought used Ryzen platform and knew there would be problems, but didn't have many... until now.

Yesterday I bought myself a pair of wireless earphones. They work perfectly fine on an iPhone or ThinkPad T495 (also with Ryzen) running RHEL8.4.

On Big Sur 11.4 however, audio is unusable. It's skipping, lagging etc.

My config:

ASRock A320M-HDV R3.0

AMD Ryzen 5 1600 14nm (AE)

12GB DDR4 3000MHz

ASUS Strix RX570 4GB

Original apple wireless card pulled from 2015 MBP - BCM943602CS

There's my USB map.

Any ideas?
