Mini-XLR is a connector, and can be used for anything. In your case it's
used for ground/left/right and there is apparently no standard for the
pinout, as seen here on reddit:
https://www.reddit.com/r/headphones/comments/rxex6h/is_there_a_standard_for…
As one of the commenters points out, there _is_ a standard for XLR to TRS
(Tip Ring Sleeve, aka 3.5mm or 1/4" connectors with two black stripes) in
the case of balanced signals.
Balanced signals are mono not stereo, and "hot" and "cold" are the
two
terminals of a single audio channel. But in your case, you're dealing
wtih a stereo signal that is NOT balanced.
Either way, it seems that pin 1 of your mini-XLR is going to be ground.
You can test whether your headphones have pins 2 and 3 as left and right,
using a multimeter on diode-check mode which will create a click in the
appropriate ear when connected. If you bring the stuff tomorrow night we
can do it together!

Hi all, I've been trying to find a Mini-XLR Female
to 3.5mm Female adapter
but I haven't been able to find one. There were a few on Amazon but the
reviews all said the left and right audio were reversed...
My current idea is to instead purchase a Mini-XLR Female replacement head
and solder on a 3.5mm Female head with attached cable. But I see different
cable styles attached to the 3.5mm, there is a 2 cable version and also 3
cable version? And it sounds like this is Mono vs Stereo? But the XLR talks
about "Ground, Hot, and Cold" and I can't tell how this maps onto the
3.5mm
cabling? If we have any people knowledgeable about audio cabling would love
help untangling this mystery, thanks!
