So I lost the adapter that came with the Lifeproof case and was really being cheap when I ordered this one. I learned the lesson the hard way :(.  The seller is not at fault here, I actually received my item way ahead of schedule.  The sounds comes through really strange, like its an echo from inside a tin can.  Tried with multiple earbuds/headphones and the problem persisted.  Just go with the real lifeproof adapter if you can find one in stock.
