Default Boom Mic - Just Mic - Help?

I have designed and built a headphone adapter/transformer
for some custom-molded in-ear headphones that offer
excellent noise isolation (passive).
I actually use them as a musician.

In the plane, they sound very nice and are quite comfortable.

So - what I want is a boom mic.
I've actually ordered/purchased a couple off eBay, and find
that they aren't quite working right. (I haven't lost much $, though.)

Can anyone point to a regular ol' boom mic (head band or holder
required)?

Quite frankly, I like my earphones better than 5 or 6
over-ear sets I've tried (and mine are not very cumbersome).
So I'd like to just buy (used of possible - money is an issue . . .)
some boom headset that has the .206/.210" connector and use
the yoke PTT switch.

Any help would be greatly appreciated!

Thanks,

Gary

Aircraft headsets normally use an amplified mic.The amplifier is usually in
one of the earcups.Some headsets did have the amplifier in a pod mounted
along the cable and if you can find one of these you could use it. Another
possibility is to make an amp. in a small box with a socket for the mic and
a shrort lead to plug into the aircraft mic socket.

That would imply that some DC votlage is supplied along
one of the conductors (much like Phantom Power in
sound mixing consoles).

Does anyone know which pin and what voltage that is at?

Thanks and regards,

Gary

Aircraft mics emulate a carbon mic. The power is supplied on the hot
mic lead from a resistor to a voltage source. The amplified dynamics
and eletrofet emulate a carbon mic.
