After building an adapter using a TRRS plug for myself, I had a
head-slapping reaction to your solution. It should work wonders for
not only the CM500, but also for most any other microphone designed to
be used on a computer - most, if not all, have the tip and ring
connected
I kept planning to build an adaptor to fix it, but didn’t get around to it.
Then I drew it out to make sure I know what was going on and it hit me. Very
much a case of “laziness is the mother of non-reinvention”.
The PTT jack was an unexpected bonus.

There's still another Koss headset - Model KS-45 that's
plug-in compatible with the Yamaha CM500. It has an
electret mic. Also about $25 on Amazon.
Look also at Amazon's listing for a RoverBeats Bravo.
Electrically and functionally (and sound) it's interchangeable
with the CM500 and - for us

No surprise. BUT -- how comfortable are they? Have you worn them

Don't electrets have to be powered (voltage applied) where dynamics do not?

My blog post was mostly about providing clean mic bias with the KX3 for
electrets that get bias from both tip and ring, like the Yamaha CM500.
Give it a quick read, it might answer some questions.

I got a quick response from David Anderson, GM4JJJ, that the Koss SB40 has a
dynamic mic. Looking at the specs at BH Photo, I agree.
I’ve updated the blog post.

Finally got around to writing up my simple hack for cleaner mic bias with the
KX3 and Yamaha CM500. Along the way, I spotted something that will make all us
cheap hams happy. It looks like the Koss SB40 ($25) is the same headset as the
Yamaha CM500 ($55).
But we really care about the better
Jim, it's true audio quality is very subjective.
For good communications quality, I personally
judge the three headsets I mentioned to be about
equal. Over the ear comfort also compares with my
over the ear headphones - a sauna for the ears. :-)
