     I think what you are describing is a fault in the 
installation and not anything inherent in the mic element. In 
fact, electrets are very quiet while carbon microphones hiss, too 
much breath noise and too much background noise are due to 
installation method. same with RFI. Virtually all telephones, 
cell phones, computers, etc, now use electrets. They are 
essentially condenser microphones with a permanent charge. They 
are simple and very rugged. Carbon microphones were once the 
mainstay of the telephone system. Widely used because a carbon 
microphone is also an amplifier so, at the time that 
amplification was expensive, carbon mics were ideal. However, 
electrets are superior in virtually every way so carbon mics are 
now quite rare.
