I can barely get my headphones to plug in on my i6. It's even harder to pull them out. It is so tight, I have to literally shove them in with force. When I pull them out, I'm afraid I am going to break the cord in doing so. This is the only issue I have with my i6 though, everything else is perfect and I can live with it. I was just wondering if it will loosen up with more use? Thanks
