recently brought the above mentioned model and i've noticed that the headphones' gold metal bit sticks out of the headphone jack - it's definitely completely pushed into the jack. Is this meant to happen? Surely the metal bit of the headphone should be fully inside the jack and not slightly sticking out - by this i mean it's very visible and looks as if it hasn't been completely pushed in. These headphones are the original ones in the box that the phone came in. I have tried another headphone and the same happens. oh by the way, the original headphones are much harder to plug into the jack than other headphones that i plug into it - is that because it's new?!
