I bought a CM-500 not too long ago. (I think it was late last year.) I
don't have any way to compare it to earlier production, but this one
does seem to have low microphone sensitivity. On the K4 I have to turn
on the preamp and set the mic gain to maximum to get 5 on the ALC meter
at normal speaking levels.
I also use it for recording a radio show on a computer sound card.
Again, I have to set the gain to near maximum to get proper levels.
By the way, for the radio show I use the equalizer in Audacity to boost
the bass. Apparently the CM-500 is meant for communications use so
doesn't have as good bass response as the mic I used to use.

I purchased a CM-500 over 10 years ago when I first got my K3. K3 is still
going strong but the headset died a couple of years ago and has since been
discarded. I've read several comments that the current CM-500's don't have as
good of a microphone as the earlier ones. Does anyone have any experience on
the latest batch of them? I always received great audio reports on my old
setup and need to purchase another headset. Just wanted some feedback before
buying another CM500.
Much appreciated
