[Elecraft] K3 Which headphones for stereo cw work? Summation

[Brett Howard]

I just did a bit of researching and considered many of these models and
ended up getting the Sony MDR-V6 based on reviews but a big
consideration for me was the THD plot on when compared to other
products.  I also ordered the Beyerdynamic velour replacement pads for
their headphones that also fits onto the MDR-V6 to aid in comfort over
longer periods of time.
