[Elecraft] KX3: Cleaner audio with Yamaha CM500, also PTT

[James Wilson]

Jim, it's true audio quality is very subjective.
For good communications quality, I personally
judge the three headsets I mentioned to be about
equal. Over the ear comfort also compares with my
over the ear headphones - a sauna for the ears. :-)

Brian, Yes, the electret mics do require a small amount of power - Elecraft
and others call it BIAS voltage. Fortunately - with the K3 and K3S and very
likely the KX3 also - that needed bias is available and can be turned on or
off with a menu selection.
