Yeah I know, but trust Me on this they know there stuff and this may trigger more responses than You think. Just go to the last page and post the schematic and the reason why and don't think it's a stupid question because it is not. I check that bad boy out at least once a day. Also do You own or are You planning on getting a pr.
it just means you can use either or, because those pins are connected internally in the headphones. so you can use 1 or 4 for signal and 2 or 3 for ground, or for balanced 1 or 4 for + and 2 or 3 for -. I personally connect to both for better contact, by striping a bit more wire and connecting across the pins
yep, thats correct, its not really necessary, but doesnt do any harm and that way there is no path into the circuit that is open to interference that isnt already driven with a signal. plus makes for more secure contact
