[Solved] Replacing the 3.5mm 4-pin Mini Jack in headphones with a microphone

Hello
Yesterday evening I had a problem with my Func hs-260 headphones. While moving the cable just under the cover of the jack, the headphones interrupted me until they stopped working. Today I wanted to prepare more or less a scheme for exchanging this plugin, but there is one problem.
The cable is attached to the headphones (allows the use of a microphone and audio) and is further divided into microphone and audio inputs. So how to solder the cables with the jack correctly? There are only three, red, green, WHITE FIBER, and black, when you need 4 wires for soldering.

I attach additional photos to illustrate the situation:

And no braid is tangled there [the screen]. As the fourth wire.

You can ask for a photo of whole headphones.

As you can see, the microphone is also detachable. It is indifferent from which side it will be connected.
And as for the fourth wire, I did not notice anything like that. Looking at the cable cut straightly, only three wires are available.

In the pictures you can not see how many individual plugs are there: [green and red] (3 pins) ?. And we are to understand that this cable was damaged next to the plug [4 pin]? Attached to the headphones.
The headphone plug is probably demountable and you can view the connections.

These wires are not a 2-strand case of each of these 3? Have you tried to gently remove the insulation from them?
They can be varnished wires of different color of varnish.

Adds such an amateur scheme here to know where the problem is

And now yes, I checked these veins and there are actually several wires in them:

-Black: Copper around white insulation, white insulation in which there is also copper (2)
-Green: Green coated line, red varnished and plain copper (3)
- Red: Only fiber (I checked 2x so I do not know why)



Now a little more is known, now the question is how to solder it?

In black, it's signal on the microphone and the copper braid is mass.
In the green copper wire the remaining mass is the left and right channel (using the multimeter you check the left and right channel).
Red is a normal nylon cable that prevents damage to the wire when stretched (it is not connected anywhere).

How would you like to upload photos from the work done. How does it look after soldering.

So what will the order of soldering on this Jack, looking at the pictures that I threw in the post?

Without measurements, you can only shoot. Probably it will be ok (if the plug is not in the Apple standard).



Like the description in black. The highest left and right channels can be swapped, but this should not disturb (you would have to check it with a multimeter).

I bought new headphones. Repairing it was hard, for small soldering elements.
