I've been watching this thread for some time and what is said below is
just busslit. No native electret mic that was ever made was 50 ohms, nor
are aircraft microphones 50 ohms nor are thelphone electret mikes 1k. You
are blowing smoke.

Ah yes, the qualifier "native". Now tell us the rest of the story.

Microphone: Noise-Cancelling M-7A Electret (nominal 50 ohm).
Mic Impedance: 50 ohms +/- 20%

Here's a couple of telephone headsets with impedences listed:
TRANSMIT SPECIFICATIONS
Microphone: Noise canceling electret
Ambient noise suppression: 13db @ 1kHz, typical
Output impedance: 1.8k Ohms typical

TRANSMIT SPECIFICATIONS
Microphone: Noise canceling electret
Impedance: Low. (~300 Ohm)

BTW, having been in the aircraft headset business for twenty years and
change, I can tell you that when a clown like this comes on asking where
to get a "replacement mic" without telling you the manufacturer and model
of the headset, he is trolling for ANY microphone that he can use to
convert a Harbor Freight type headset to aircraft use on the cheap.

Or a DC military headset which you can buy cheaply on ebay along with a
cheap 1 to 2 plug adapter, but they don't work worth a crap unless you swap
the mic.

So which of it is it, jerknose? You bought a stolen military headset on
ebay or you are trying to convert a Best Buy stereo headset to aircraft use?

I'm not the one looking for a mic, Edison.

I have 4 headsets, all bought new from a reputable dealer, but thanks for
your heartfelt concern.

Chill everyone!!

I'm the one who needs the microphone, this thread has morphed like most
others and has gone off topic.

I'm sending in my PCA(aka. lighspeed) ANR back due to popping noise in
the earpiece and found my backup headset sounds like I talking through
an old fuzz box.

My mistake is, I'm living 1500 miles away from home at a contract job
and a spare microphone from an old Pilot headset is in Dallas somewhere
and I'm in Connecticut.
Still, no one has come up with an old microphone. I suspect lots of
people have them laying around in old crappy headsets.

ARGH, I'll have to resort to an hand mike until my other comes back from
the factory.

Really? Even if it's really old?

I now have two out of four of my headsets with dead mics, and it's very
annoying.

I'm not so sure they still do. At one time a dealer could send your headset
back to DC and they would fix pretty much anything for free. My dealer
informs me this is no longer the case although they might still make minor
repairs for free. I've never tried having one serviced during a fly-in, so
that's certainly worth a try if you can find a rep out in the field.

They did this to a friend's at Sun & Fun circa 2000.

I had a DC repaired around the same time. Used to be you could send them a
frazled hunk of crap with a DC logo on the side and they would send you back
a fully overhauled headset with new ear pads and a new mic cover. It was
just last year my dealer was telling me the only company still doing major
out of warranty repairs for free was Lightspeed. Perhaps she was just
blowing smoke and was trying to sell me Lightspeed, I don't know, but she is
also a DC dealer so I don't know why she would.

It would be interesting to see if anyone has had a DC repaired for free
lately and what those repairs were.
