[Elecraft] Icom headphones giving trouble?? (K2)

[Michael Harvey]

I have tried to use my Heil head phones I had for my IC-746 on my K2 and they don't seem to work
with the Heil Kenwood adapter Elecraft said I needed.
 
I normally use CW but thought I would play on SSB this morning.
 
I have a Kenwood dynamic hand mic (500 ohms) and it works but audio reports aren't great.
The head phones have always had great audio but I can't seem to get them to work?
 
Do these head phones need a powered mic element. They are made for Icom radios and have an IC on the mic boom pivot.
 
Any ideas??
