My headphones won't work in my iphone 4s?

I put my head sets in my iphone to watch a video and they won't work, I took them out and the sounds fine on my iphone. My head sets were tangeled so I Untangled then and that was not the problem. I wiped the end of the head see were you plug it in and it won't work. It use to only put sound on one side of the head set and the other mute. Do you think there something wrong?

If you have a spare headphone try it and see if it works. If it doesn't than its an issue with your iPhone. I found the problem it was the head phones themselves I tried another head phones and they work so the problem solved Hi headphones come with different impedances so some will work and some will not. So time to only use what should be used.
