Yes, in the case of the 770 you would just need a cable with 4 conductors to make it balanced. Installing the 4-pin mini XLR would make balanced possible as well. The thin cable between the left and right cups that's routed through the headband does have 2 conductors in it.
No worries. Thanks for all the information.
So, I ordered a 2 pack of 4pin mini-xlr panel mount male connectors, and mating female plugs on Amazon. They were a little pricy, but MUCH cheaper than buying everything ready made.
I also ordered a balanced 4pin male to female balanced XLR extension cable, so I can lop off one connector and attach the mini-XLR plug, rather than wiring it from scratch.
Rather than using the flimsy stock wire that goes across the headband, I am considering making my own twisted pair from some wire I have around the house. I'm not convinced this is necessary, but it kind of feels like the right thing to do, if I can make it fit right.
One thing that concerns me - however - is whether or not the back of the panel mount mini-XLR connector will fit inside the cup without interfering with the driver.
In this guide on youtube they actually cut up the metal bracket holding the driver in place to make it fit. I find this rather disconcerting, as this could potentially harm the sound quality significantly. I'd imagine the balance, stability and position of the driver within the cup are key.
I'm hoping mine will fit without having to cut the bracket, but in case it doesn't, what is your take on this?
