"After saving broken headphones that have opposite sides broken, I fuse them together as best/fast as I can, so I don't have to buy new ones. Note the two cords, the headphones require two audio jacks to use."
Setting aside the obvious explanation that the power cord is attached to something on the other side or below the wall, maybe the wall itself is electrically operated, and it needs to plug into itself to run. Woah. I just got goosebumps.
