I was discounting phantom as a source of current.

The capacitor in a microphone is of a very high grade,
with virtually no losses, and there will indeed be a very high current
flow momentarily (English meaning of this word - ie for a moment, not
sometime soon) as the diaphragm hits the back plate. While I wouldn't
expect it to actually cause attachment, it would not surprise me if it
blew a tiny pinhole. Accumulate a few of those and you could well do
audible damage.

Ok, then will you buy an energy argument? I'm too lazy to
plug in the numbers right now but I can't believe there's
enough energy on that little capacitor at 48 volts to
measurably raise the temperature of a mouse tear.
