The mic plug is shorting the “mic button” (PTT) contact. Set MIC BTN to OFF in the menus or use an off the shelf stereo to mono splitter.

The splitter also gives you cleaner mic bias and a PTT jack. https://observer.wunderwood.org/2015/08/16/yamaha-cm500-headset-with-ptt-on-elecraft-kx3/ wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Jul 5, 2019, at 12:19 PM, Michael Heit via Elecraft > <elecraft@mailman.qth.net> wrote: > > I bought the Heil headphone set up with my KX3 but have never been able to > get the mic to work right.
