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.

I have some Radio Shack FM walkie talkies that worked on this
principle...Forgot I even had them till this came up. Now where'd
I put them?
