Well I think I figured it out now:

The 2 headphones are connected in series (white cable) and the mic is connected separately (black cable).

Both black and white cable are connected to the headphone input jack.

I call the headphone piece in your image the''' left '''piece.

The connectors on the left headphone piece I call 1 to 3 from left to right:

1.) Left headphone V+

2.) GND

3.) Right headphone V+ (it's just soldered there  to hold it in place, it's not actually connected to left headphone)

The wiring to the jack is exactly as on the photograph of @jayeff
