[Elecraft] K3 & Heil headset

[Kate Hutton]

My new K3 works great on CW - love the way it sounds & the intuitively
logical controls - but I'm trying to figure out what part I need if any to
connect my Heil Pro headset, with a PTT hand trigger.  I see a larger stereo
plug coming from the PTT switch & a small one coming from the heaset (1
wire), which currently go to a Yaesu adapter to my old rig.  The other two
wires to the headset appear to be for the earphones (small stereo plug).

Can I use "PTT IN", "STEREO PHONES" & "MIC" on the back & just ignore the
8-pin connector on the front?

Sorry if it is a dumb question.
