Hardly. :)  W6XU introduced our contest club, NCCC, to the CM500 several 
years ago. Over a period of ten years or so, I've evaluated perhaps as 
many as a dozen cheapo headsets with electret mics. ALL of the mics work 
fine and sound good with the K3 and other rigs, but there is HUGE 
variation in the quality and comfort of the headphones.  I've seen 
reference to a Koss model similar to the CM500s that is described as 
comfortable and sounding good.

Yes. Some of the first I tested were from a salesman's sample kit of 
Plantronics products. All worked fine, but none were comfortable. Ditto 
for several computer headsets I bought a few years ago for use with Skype.
