Alan,

The CM500 has always had an electret mic, which requires bias, although 
the data sheet has always called it a dynamic mic. As a test, turn off 
bias and see if that changes anything. If it is a dynamic, turning off 
bias should make it work better.

My WAG is that what you bought might be a counterfeit. My experience 
buying all sorts of things in the last 5 years (kitchen tools, shoes, 
etc.) has been seeing lots of what appear to be either counterfeit or 
cheapened versions of stuff I'd previously owned and wanted a second one.
