I had this problem and I couldn't find anyone who answered the question in the way that was relevant to my situation. What happened to me was I took the side of the beats that has the charging port completely apart and found that red wires that connected the charging port to whatever eventually goes to the battery had snapped. I cant imagine how it happened seeing as they weren't exposed at all but it did. I was able to fix it by drilling a new hole in the middle part of the headphone to put the wires through and then twisting the wires together (make sure to strip the tips of them first) and finally hot gluing them together. The issue with having two wires is that you don't know which wire goes to the other. I would recommend just not applying the hot glue until you know that the wires will work.
