Electret ("condenser") mics also show a bass boost when worked close as
with a headset or close talked hand mic. That's why - in addition to
limiting hum and background noise - it's generally best to set the K3's
two lowest EQ bands to -16 and set 200 Hz to -6 or so.
Low frequencies contribute very little to intelligibility but consume
a lot of transmitter power.
