My I phone won't come off silent keeps saying I got headphones plugged in

When you turn your phone on and off silent at the side I tried turning it on and turn the ringer volume up but it said that I had headphones in so it won't ring or play any media it only plays it I put my head phones in I check to see of it was the speakers by changing my ringtone on settings but it worked and played fine it's just that my problem is it won't come on loud and it says I have headphones plugged in?
