>>> An electret mic has much better fidelity than an inexpensive dynamic mic, 
>>> so the CM500 is probably a better choice.

Is that really true? If you looked inside all of your local AM broadcast stations, all you'd see are dynamic microphones. 

I'm not sure why most headsets have electret mics. Maybe it's because they have a higher output which lessens the need for a lot of preamplification? I don't know.
