The majority of condenser mic's use extrememly high impedance circuitry, 
even gigaohm resistors, so humidity is a problem. Low impedance RF based 
models exist and are favoured by outdoor wildlife and location sound 
people. Half an hour web browsing would be informative :)

Mobile phones now use MEM mics but I am not aware of "serious" 
audiophilic users of MEMs but I am not up to date. MEMs diaphragm 
capture area is very small.
