Yes , there was a friend of mine who developed earn pain after using headphones daily for 6 months. He was using it almost 5-6 hours daily and yet he developed ear pain. I never used headphones anytime because I am too much cautious regarding my health.Well, wearing headphones and in-ear headphones can be bad for your ears. I have tried wearing in-ear headphones for a really long time and it causes pain in my ear. I have seen many people wearing headphones for a really long time and how they are able to do it is just beyond me.
