Years ago Jabra made a cellphone headset where the mike was in the earpiece,
and worked on bone conduction. The mike was not on the cord. The real
advantage to this model was that you would put it under the cup of your
headset, and use the cellphone while in the air. It worked rather well. I
still keep mine in the flight bag as a backup.

Regarding in-the-ear microphone/ earphones....

Someone in the thread mentioned in-ear headphone/mics for cell phones
being simular. The cheap ones you get for free from your cell dealer
are just a cheap ear-bud and a omnidirectional mic inline with the cord
a few inches down from the earbud. They perform poorly on the ground
with a cell phone, I doubt they would be even worth trying in an
aircraft (think of the opposite of "noise cancelling" microphone....)

A better unit is the Jabra in-ear headset - it looked like a small
black, corded version of the earpiece that Lt. Uhra (sp?) used in the
original Star Trek. It didn't actually use bone-conduction for the
microphone, but had a tiny microphone opening in the black part that
stuck out, popinting towards the lower front of your face. There were
semi-form fitting "ear gels" that came with (Small, Medium and Large)
that you chose to match your ear size. They worked pretty well,
although you had to be careful so the mic hole pointed correctly. The
ear gel idea was ok, if you had "Small" "Medium" or "Large" ears. Those
of us that fell in between, compromised. I will say that once you got
the fit right, they worked well and sounded good, both tx and rx. They
also had a cheaper version with a stubby boom microphone. I just went
to the Jabra website (www.jabra.com) to see what the model number was
and see that the ones described above are nowhere to be found. Progress
(?) I guess. (I did find an example he

http://makeashorterlink.com/?W326430FC - looks like they are
clearancing them out, considering the prices....)
