The SIGNAL wires are switch between normal and fail-safe
configurations, not the ground wires. It's the ground wires
of the headset that are probably sharing current pathways
with ground wires of the strobes that generate "the loop".

Went to the hangar today and tried with the mic and headphone jacks off of the
panel ( in my hand to make sure they were isolated) . No luck, but a great thought....
NEXT? THis is getting to be a bummer.

Then the 'loop' is somewhere else. Since the interference
is detected with the intercom OFF suggests that the problem
does not lie upstream of the intercom but downstream. Do all
your panel mounted electro-whizzies enjoy a common ground?
