Bluetooth Audio -- Crackling Sound

I have been using Arch Linux (on my desktop) for several years now and none of my bluetooth headsets ever worked with Arch. Audio is always crackling or coming in pieces on bluetooth. It was the same for Pulseaudio and now Pipewire has come and I still can't get rid of crackling sound. As of today, I have tested and my current headset works fine in Ubuntu 20.04 that I have on my laptop.

Pipewire is rinning as per systemctl --user status pipewire.service:

[arnuld@arch64 ~]$ systemctl --user status pipewire.service
● pipewire.service - Multimedia Service
     Loaded: loaded (/usr/lib/systemd/user/pipewire.service; disabled; vendor preset: enabled)
     Active: active (running) since Sat 2021-03-13 09:30:50 IST; 16min ago

     CGroup: /user.slice/user-1000.slice/user@1000.service/session.slice/pipewire.service
             └─1524 /usr/bin/pipewire

Here is the output from pactl list sinks (I have removed everything except of bluetooth output):

P.S.: I have bluetooth speakers too and they work fine with bluetooth on Android mobile but same crackling sound on Arch Linux.
