Bavman may be suggesting that an xlr can be used to make a trs cable detachable, like how AKG does on some headphones like K702.

From what I catch, so in balanced mode there is no ground like in conventional headphone?
The ground is used as a shield, without connected to the driver.

So, on the left trs, tips connected to the left driver~ring connected to the left driver~ground(ground in conventional hedphone) is used as shield(if have shield) without connected to the left driver.
So on the right driver.

That's true?

balanced mode there is no ground - there is signal positive and signal negative for each side (left and right). Some people connect the shield to ground on the amp side, and not connect it on the headphone side for additional noise rejection, but it is rarely necessary in this usage.

need to learn litz braid... but its confusing! using double twists is getting boring already =(

Take 4 wires, take the leftmost wire over the 2 next to it, take the rightmost wire over the one next to it, take the leftmost wire under the two next to it and over the third, then repeat from the start until finished.

That creates a flat braid. I like round braids better because they are usually more flexible and looks nice imo.
But for any kind of braid, there exist google/youtube to help you out. It takes no more than a couple minutes to learn

Yup, this is what I did to get my round litz braids. Sometimes I zone out and screw up and have to go back a few steps

Not so bad for 4-strand, but backtracking on an 8-strand is not fun at all.
