What pin goes where? How would one solder TRS-Female->XLR and
XLR->TRS-Male adapter cables in order to use a mic cable as a headphone
cable? Run phones over a snake.
I would think you will have a tremendous amount of left-right crosstalk.
No, not enough to actually hear.
The two wires are twisted and unshielded with respect to each other.
But the impedances are low enough that it might only be a problem
if you were going thousands of feet. I've never heard any crosstalk,
even when listening to just one channel.
For that matter, headphone fanatics construct special circuits to
purposely introduce a bit of "crossfeed" when listening to headphones
to counteract the common "hole in the middle" effect.
Don't do it.
It has been done for decades. I've personally been doing it for decades.
I have absolutely no reservations recommending it heartily. It is a very
convienent way to extend headphone coverage.
The only potential pitfall is accidentally plugging the adapter into a
mic line with phantom power applied. It likely wouldn't ruin the
headphones, but it may give your eardrums a good POP if you
are wearing them at the moment.
