Aircraft Headset to Cell Phone?

[Wayne R.]

I really need a David Clark or similar headset to work with my cell
phone, either cabled or Bluetooth - so long as it works!

I don't have $850 to spend on a fancy new Lightspeed headset, and I'm
no pilot, so I don't need a headset to also work with a radio.

Can I ask for some assistance in figuring out what to get and how to
rig it so it'll give me all the noise attenuation (for both ears and
mic) that these things are capable of?

I'm pretty good at soldering, parts sources, eBay, etc. But I need
some deeper technical insights to match impedances/I-don't-know
between devices.

If I can get one to work well, I'll make a bunch for the guys I work
with.

Just need to figure out how to connect a headset to a phone. My guess
is that hams could do this better than anyone...help?

So far I have not found a web site that shows what I want to know
about head sets and how to make them work as I would like.
I can share a little of what I have found...

Audio folks seem to be more concerned about levels than impedance.

Aviation microphones either look like Carbon mics or really are carbon
mics. Carbon mics need external power.

Computer Mics are of the electret type and require a voltage source of
4 - 9 volts. They are high quality/price ratio.

Old telephone modem adapters are a ready source for good, small, cheap
isolation transformers.

Good luck!
