Hifiman Sundara headphone wiring

 I got a request for cabling information for Hifiman Sundara headphones.

The following image comes from a company selling a cable that is supposed to be Hifiman compatible:

 

4-pin and 3-pin Balanced XLR cables

 I got a question about how to do a 4-pin balanced audio XLR plug to 2 3-pin XLR plugs:

Could you make the diagram to split the signal to TWO 3-pin XLR?
Channel Left and Channel Right

Here's my picture of a female 4-pin balanced XLR plug (top left):

Here's a picture from https://robrobinette.com/BalancedCable.htm showing the mirror-image male 4-pin XLR plug:

Here's the pin-out for a 3-pin XLR from the same site:

WARNING: Do NOT make a stereo 3-pin XLR to 4-pin balanced XLR plug! That plug combines the ground/negative wires for the two balanced channels, and that can ruin some equipment (ironically, only the more expensive equipment!)

So let's draw up both the 4-pin male to two 3-pin female, and two 3-pin male to a 4-pin female:

I'm using the "pin numbers" from the 4-pin XLR to number the wires coming in/out of the 3-pin XLR plugs.
