Most of them consist of a FET transistor with the base floating, and
picking up signal capacitively. So any static spark can easely destroy
them, when you touch the connector.

** Hog wash.

Electret mics are not subject to any such failure mode.

In any case, the OP's mic is probably dynamic.

Yep, that's the one. Funny how quickly they self-destruct.


** The mic capsule is very small and the impedance is 600ohms = lotsa hair
fine wire used in the voice coil.

Hair fine copper wire PLUS crappy Pb free solder = recipe for sudden
failures.

Hint: It's the flux....
