Under your earpiece should be a piece of black tape that covers up some gold contacts for an antenna. I believe it's the wifi antenna. I had an issue with a customer where the black tape was missing which caused it to ground out. As far as the headphone jack goes, I know it's strange that you are having the exact same issue, but I'd try one more head phone jack/lightning cable assembly. This time connect it externally by just connecting the cable to the motherboard. Put a piece of paper under it so it doesnt ground out on the case or any other metal and see if that helps. If it does work, then the assembly is grounding out within the case when installed somewhere.
