This was a working headset. The cables were fraying, so I ordered some replacement cables and new foams. I opened up the controller to install the new cable set, and I accidentally broke the pcb connection that goes from the batteries to the control board. So at that point, I put it together and stopped doing repairs...

Maybe somebody more handy then me can solder a new pcb end. Unit sold as is for parts or repairs. Includes some new cables and pads. Please see photos.
