[SOLVED] Rewiring 3.5mm TRRS CTIA headphones

[thefxgamingrules]

So, I'm rewiring a pair of broken headphones (with an inline mic), which use a TRRS CTIA 3.5mm connector.
I can't figure out the following-

1. All components (drivers and mic) share a common ground?
2. If the above is correct, then the mic gets only one ring and the ground (sleeve) connector. How does it transmit signals?

I'm using that image as a reference.
Any help would be appreciated.

1. Yes
2. It is an analog microphone. It only needs a signal wire and a reference plane (ground).
