300-3300 Hz or thereabouts.

Not helping are the modern designs, especially Bluetooth headsets.
It seems to be thought that the farther the microphone is from
your mouth, the sexier it looks - but the more ambient noise it
picks up as the gain increases to compensate for the increased
distance from your mouth.  A properly adjusted boom mic used in
aviation or other noisy environments will almost touch your lips.
(Hey, sort of like classic telephone receivers...)
