I am not sure if I understand correctly your setup.

Headphones are not to be used with HSP/HFP if they do not have a mic (if
they are not a headset). In the case it is only headphones you should use
A2DP with Sync (bluetooth)

The Mic of your webcam would be then a Source.
You need pulseaudio-module-bluetooth installed (check).
You need pulseaudio set correctly

Check
        pacmd list-sink-inputs
        pacmd list-source-outputs

might be you have to set input/output manually
