Oculus rift headphone jack adapter

These are little caps that can be installed on an oculus rift to make a headphone jack adapter. For the headphone jack adapter I used a RCA to 3.5mm adapter and chopped the ends off. Wired it into the caps. and used some screws I had lying around to screw the cap onto the oculus, in place of the stock headphones. I am not sure what size screw I used as I had them laying around. The screw goes through the cap, which also holds down the wires and then screws into the oculus.
