the FHM-1 flex... bad
While waiting for an adapter to arrive for my Heil headset, I gave the Flex mic a try. All reports were positive with comments like perfectly fine, easy to listen to, etc.
I have the mic switch (on the back) set to #1 (flat), and the EQ set for a 1-2 dB rolloff at 125 & 250, and a presence rise of 2-6 dB from 1 to 4 kHz. 63 & 8K at -10. This is a perfectly serviceable hand mic; I don't know what all the fuss is about.
