[Elecraft] headphone impedance

[W2RU - Bud Hippisley]

The headphones I have used for over a decade are 600-ohm high-end stereo high-fidelity phones.  I obtain “comfortable” audio with my audio gain control set at about 9 o’clock.  I am 99% CW, and they are my preferred-by-far headphones for both the K3 and the K3S, although I use something else when I need an integrated headset for phone contests.
