RE: 4-pin XLR connector question

You mix up two things here.
Balanced Signal Transport via great Distances (3Pin XLR).
And Balanced Signal generation in the Source.
When you want to drive Your Headphones in the (2nd) balanced Mode, you first need a source, that is able to produce a balanced Output.
(See Bridged Mode)
So, in essence, you need a Source, that could normally drive two Pairs of Headphones, as it sports two independent stereo amps. Now you bridge each of the two amps, so that the left channel of amplifier one produces the positive half of the Wave, the right channel of amplifier one produces the negative half - for just one side of the headphones. The two channels of the second amplifier do the same for the other side of the headphones. This resulting in the quadruple amount of Power, the amp could otherwise produce, with the extra bargain of winning 4dB more s/n ratio.
And, yes, you only need the 4 pins.
