John and Charles:
The Heil Prosets with the HC-4 or HC-5 elements don't have quite enough
output to drive the K2 without either an external preamp or tweaking of
the K2's internal circuitry. The version with the electret element
seems to work better with the K2. I believe the Heil K2 Proset is
essentially the version with the electret element, but I'm not 100%
certain on that matter.
All Prosets require an adapter to match your particular mic jack
configuration, so that is not a factor.
No idea about the K3.
73's,

I see that now Elecraft is offering sale of a Heil K2 Pro Set
mic/headphone unit, saying it is "optimized for K2." I assume that
also means K3.
Charles brings up a good point. What is it that makes any microphone
"optimized" for any radio. Pin outs are obvious of course.
- Impedance?
- Bandwidth?
- Signal Strength?
