'[EE]: Anyone know pinout of most electret mics?'

Wondering pinout of the most common electret microphones.

So far looks like tip is not used, sleeve has audio and bias on it and barrel has ground.

O  <- tip (no connection)
||   <- sleeve (audio and bias)
||   <- barrel (gnd)

Is this correct?

Thanks.

Not on any I have seen
Tip is signal and bias on a mono plug. On a stereo plug, tip is
output and bias goes on the ring. Barrel is Gnd in both.
