Really screwed the pooch here...
Long story short, one ear cup became…detatched…from the headphone wiring (and also the pads on the PCB) before note was taken of original placement. Now if the pads on the pcbs were the same we wouldnt be having this conversation. The original wires(from top to bottom of yellow PCB) are red/blue/white/red-gold/green.
There are no inner wires in any of them, just the cloth strings for strength. The markings on the pads (blue pcb) read(from top to bottom:): Batt/TS/GND/speaker-/speaker+.
Yellow pcb reads Batt/what im pretty sure reads 'mic'/GND/
Now intitially i soldered it together as shown here
But it left a horrible buzz in the left ear and no mic. Any
