Strange, maybe yours is broken?
Sound from mic should be quiet good, like on Windows or Android (mono 16 kHz, or even 48 kHz if your headset supports FastStream codec).
I have also Zoweetek B0310, this one also works for me but it doesn't have auto profile switching.
I'm using Lenovo T480, ArchLinux with kernel 5.10, pulseaudio 14 and latest Gnome.
