Frank,
For the K3S, just plug the microphone and headphone plugs into the rear
panel jacks. Set the MIC SEL to RP and turn bias on.
For the KX3. the easy way is to just turn MIC BTN off and plug it in.
That microphone needs bias, and it will be supplied by the digital DC
that normally is used for the MIC Button functions.
The harder way for the KX3 is to make an adapter (but it is not that hard)
Be aware that, like most computer microphones, the tip and the ring of
the plug are wired together - so if you make an adapter, you must use a
stereo jack so the audio is not shorted to ground.
If you make an adapter, you can include a connection for a PTT switch,
but without that, you can put the KX3 into transmit with the XMIT button.

Phone newbie here. Any recommendations on off-the-shelf cables or
adapters, and a handheld switch, to enable use of a Yamaha CM500 headset
along with PTT functionality on both a K3S and KX3?
Thanks much,
