Just because you can doesn't mean you should. Of course you can throw 
money at the problem by buying these products. A fool and his money are 
easily separated. :)

Very good sounding mics built into gaming headsets like the Yamaha CM500 
and a similar Koss model plug straight into the K3 and KX3 and sound great.

I looked up this mic and tried to find specs. There's nothing there -- 
it's all silly putty.  Every place I looked said something different. 
:)  There's no response graph, not even a description of what connector 
is used and how it is wired!  Inside that mic is a cheap (maybe a buck) 
electret capsule. The shiny enclosure is simply designed to facilitate 
the separation process noted above.

I'm retired from a career in pro audio, A Fellow of the Audio 
Engineering Society, and have a closet full of REAL pro mics that I use 
for recording music. The only one I'd consider using (and have used) for 
ham radio is an RE16, a variable-D dynamic with a good blast filter.  I 
used it because, at the time, I didn't have anything better, because the 
variable-D construction eliminates the LF boost of proximity effect, 
and, because it's a dynamic, all I had to do was solder up a cable to a 
connector that mated with the rig.

List members K4TAX and W4TV are also retired broadcast engineers, and 
I'm sure there are others.
