I haven't tried it with a KX3 because I don't have one yet. BUT -- 
almost any standard electret mic will work with a K3 and KX3 if the plug 
is wired properly, and nearly all computer headsets are electrets.  
Check the manual for instructions about wiring and menu settings.

Nearly ten years ago, I bought what was probably a Plantronics 
salesman's sample kit of a half dozen different headsets designed for 
cell phones. I made up cable adapters for them and tried them with the 
ham rigs I owned at the time. All of the headsets (both mic and 
headphones) worked fine with and produced great, competitive audio on 
all of the rigs, but some were a lot more comfortable than others.

A year or so ago, I bought some el cheapo computer headsets for use with 
Skype. I recorded them on my computer and listened to them, and I tried 
them with my K3. They weren''t very comfortable, the headphones didn't 
sound very good, but the mic sounded very good on the air. All I had to 
do was plug them in the rear panel (which is a 1/8-in TRS jack), select 
the rear panel jack, and turn on the bias.

With the KX3, simply set the menu per the manual, plug the mic in, and 
you're good to go.
