Question Headset Microphone Impedance
Just been told by our company that we are no longer allowed to use Bose headsets on our Embraers as the microphone impedance (5 Ohms) is outside the manufacturers limits 50-150 Ohms.

Please could someone with a bit more technical knowledge explain this one to me . . .
