Yes, aviation headsets use different size connectors for the mic and
phones. I believe the headphone use a standard 1/4" and the mic is a
.206" (5.25mm) plug. I made an adapter to use my aviation headset on
the K3 but got reports of garbled audio (probably RF getting into the
cable or my adapter). I did get good results using the noise canceling
headset for RX and a boom mic for TX.

Am setting up a newly acquired used K3 which came with no microphone. Is
it possible to use an adapter to make a Lightspeed Zulu noise cancelling
headset work for the K3. I got very nice reception using the cell phone
attachment line but can't identify any microphone function. The two main
lines are different sizes, per standard aviation usage.
