[Elecraft] K4 Headphones Q

[Rich NE1EE]

I have been following this thread with interest. I am considering the Bose QC-35 headphones. I wanted a boom mic to go with, but I have not found one with decent reviews. Has anyone experience with one that works w the QC-35 II? I guess that by plugging into the headphone the boom mic disconnects the internal mic. It looks like that mic then plugs into my rig using a TRRS, and feeds mic and speakers. Is this the way it works? That would make the plug into the ear cup a speaker feed? I could see almost any good mic working, even if what I needed to do is run 2 cords: one for the mic and one for the audio. That would let them work for CW. And otherwise, there should not be a problem?
