I've owned and loved the Etymotic ER4S for many years. Originally bought 
them for professional use, as monitoring headphones when recording live 
jazz when I'm in the room with the band.  They also work quite well with 
every radio I've tried them with, including the K2 and the K3.

I'm not aware of a model that includes a microphone -- this must be 
new.  It should work fine with a K3 -- simply connect the right wires 
and turn on the bias.  For TXEQ, I would start by using max cut of the 
two or three lowest bands and then asking for signal reports from 
someone whose ears you trust.  Have them listen with their IF bandwidth 
set wide. You may want to boost the higher bands a bit. or maybe not.
