The skunk works here is toying with a microphone-less headset based on the
principle that your voice box is inherently interconnected with your
eardrum. Sort of a God-designed sidetone, if you will.

Earphone in one earcup, microphone in the other earcup. Nothing sticking
out front, and no fiddling with that "magic spot" that isn't too weak or
overmodulated.

The space program has had those for ages. The propellant handlers that have
to work in SCAPE (Self Contained Atmospheric Pressure Ensemble) suits used
one for their intercom connection. It was a single in the ear combined mic
and earpiece. "Look ma, I'm talking thru my ear!"

The one thing that I remember was that they had custom molded earpieces.
Supposedly for two reasons. First, to make sure it stayed put. Second, to
get solid contact for better audio transmission in the high noise
environment.

Good luck with the project.
