Laptop's jack works only when pin of headphone is bent

hi..!
my laptop's audio jack works only when I insert the pin of headphone at a certain angle. The problem is with my audio jack. Headphone works perfectly with other devices and also same problem occurred with the other headphone when I used it with my Lappy's audio jack.. What i do ryt nw is insert the pin of my headphones and press it only then I can hear from it.. :(
