...A senn HD650 headphone cable in half, how many wires would I see. 2 or 4?

Im going to diy a lead and was just wondering how much cable to buy.

Thanks.

You would see four wires. Two orange, one red, one green.

It depends on where you cut it.
If you cut it close from the connectors to the Headphones you'll see two wires.

But if you cut it close from the jack connector you'll probably see 3 or 4 wires.
Why 3 or 4, it is because sometimes there are two grounds sometimes not.

I don't get where this is going.
Two wires at the headphone end, and 3-4 at the jack?

Admittedly, I haven't spliced a senn cable, but I don't think this is likely.

Theres one of two possibilities as far as I can think of -

1 'wire' at each headphone connector, and a shield on each that acts as ground.
The shield extends all the way to the plug. (one can argue that a shield=wire [or to be technically correct, each conductor is made of multiple strand of wire])

or..

2 wires at each connector - they all extend to the plug.

If you cut the red wire, we're all gonna die! /panic

Well, the cable are split half a meter or so from the headphone end. Meaning that there goes two cable to each headphone channel, while below the split there are either three or four cables (common ground or not).

There will be 2 wires going into each connector, a signal and a ground. There will be 3-4 wires going to the 1/4th jack dependent on whether the ground is split higher up in the cable (at the y to each cup) or whether their are 2 seperate jacks that meet in the plug.

I misunderstood. I didn't know he meant 2-wires "per" earpiece.
Still yet.. each channel remains isolated until it gets to the plug. There will still be 4 conductors until then.
