[Elecraft] headphones for k3 / kx1

A fairly decent pair of cans that can be had for a quite inexpensive
price is the Sennheiser HD 201.  For slightly more the HD205 will
produce a set of cans with better low frequency response.  The 205 

The HD201's are rated at 108dB/V where as the HD205 is 112.  However the
impedance of the HD205's is higher.

These are two decent choices that are fairly inexpensive.  Many of the
higher quality full sized headphones a quite inefficient and are
probably not going to provide satisfactory volume levels when coupled
with the KX1.

However being that you mention the K3 you'll want to either ensure you
use higher impedance headphones or ensure that you change the series
caps in the headphone circuit from 10uF to 100uF.  This change makes a
lot of difference in low end response of the K3.  It was VERY noticable
when I made the change to my rig.  I have the Mouser part number of the
cap that I used which fits directly onto the pads on the Main DSP board.
However note that it is quite difficult to get the original parts off
cleanly.
