To this day i still plug my wh-mx10004 … (Or whatever their stupid number is cause sony thinks a ten digit alphanumeric code is the catchiest name for their products…) b/c every time they connect by bt they will ONLY do ‘handsfree’ codec, yknow, the one that sounds like shit for phone calls. I have done everything… pavucontrol, pipewire, wireplumber, blueman, cli system level shit and yes i can force it to proper high def audio after some really annoying steps… but then ill start up a game or something and it suddenly goes “nope! This calls cor handset audio!” And switches itself back.

If you're talking about WH-1000XM4, they work for me. Sometimes on first connect they only have mSBC codec for me too, but if I just disconnect/reconnect them then all other codecs appear. If I switch to SBC-XQ or LDAC they then work fine until I turn them off (which can be hours and many different playback streams). I'm on pipewire+pipewire-pulse.
