Question DIY replace jack plug: strange colors

Hello Everyone

I have a PHILIPS SHP2000 headphone. The jack plug is broken. So am trying to fix it. I also have a grey audio cable with a jack plug on each side. So i thought if i cut off the plug from the headphone and cut off 1 plug from the audio cable and connect the two wires then i will even have a longer headphone wire

The strange thing is. The audio cable wire has the normal red sleeved, white sleeved and no sleeved cables within the main grey sleeve. But the headphone cable is strange
The headphone cable had two black sleeved cables.
1 black sleeves cable contains: a blue and green string of wires.
the other black sleeved cable: contains red and copper colored string wires.
The individual wires are actually colored. No sleeves around them. How does that work My mind is blown.

Thank you guys very much in advance for the advice

They will be enameled copper wire. The enamel coating on the copper wires acts as the insulator.

You can solder enameled wire by scraping the enamel off the end of the wire with a blade.

Or just heat the wire end with the iron. The heat burns the varnish off allowing it to be soldered.

One thing to add.. I use this method myself because it's fast but the heat needed to burn off the coating will also weaken/thin the insulating coating 1/4" or more past the point you applied the heat so be careful that length doesn't rest against something that could possibly short. or add a length of heat shrink tubing to insulate that area better.

Identifying L and R is easy with a meter. Identifying phase I think you would have to listen and swap one pair over to see which was the correct phase.

There probably is some standard for these but I would want to be sure by listening.

When I have to do this, I tear apart the original jack and copy the connections on the new jack.

I'm not sure there is a standard for this.

Identifying the L and R pairs is easy with a DVM on ohms/diode range. They will click very loudly.

1/ Connect one wire from the left earphone to the plug tip.
2/ Connect one wire from the right earphone to the plug centre.
3/ Connect the two remaining wires to the plug body.

Listen to the phones on MONO speech (radio ?) and if it sounds 'phasey' without a distinct centre image then reverse the connections to ONE earphone only.

Idk how to use this DVM on ohms/diode range. i need another method.
but i'll try the
1/ Connect one wire from the left earphone to the plug tip.
2/ Connect one wire from the right earphone to the plug centre.
3/ Connect the two remaining wires to the plug body.

then after i'll see if its correct sounding or not.
