I have found the 5' cable that came with my Ety ER-4P is way longer than I need. So, I determined that I would shorten it to about 2.5'.
I carefully cut into it, and isolated each of the cables. There were (3) very light gauge insulated cables, white, black and red, plus a flattened silver (uninsulated) cable that wrapped around the other three.
I have successfully shortened the cables, put it back together, and it works just fine. But, I was hoping that someone could explain to me exactly what I found inside.
I'm guessing that the red wire goes to one IEM, the white wire goes to the other, and the black wire is a common ground. Is that true?
Plus, as I stripped the insulation off of each of the coloured wires, there was, in addition to a very fine guage wire, a fabric cord of some sort. Does anyone know what this cord is? Is it just strength reinforcement? Something else?
Lastly, is the flattened, uninsulated silver cable that is wrapped around the other three cables 'shielding'? That's my only guess.
Can anyone enlighten me?
