Hmm. I'm on a stock Arch install and had no latency or quality issues to speak of. Bluetooth works out of the box using `bluez` and `blueman`, though Bluetooth is still Bluetooth, with inherent latency. Some headphones have low-latency modes that can be activated in their respective apps at the expense of ANC/battery life, maybe that'll help?

The apt command you're looking for may be the audio backend, though. `apt install pipewire wireplumber -y`. Won't break your existing pulseaudio setup, but will allow low-latency operations. (I think--I avoid the dumpster fire that is Ubuntu like the plague, so ymmv)
