My iphones porthole to plug in my earbuds isn't working?

Probably broken

Is it the Port hole or the wire on the Ear Buds that have broken. The wires take a lot of abuse from twisting and turning and is more likely the problem, unless of course you have tried another set of Earbuds.

Go to the link below and see if this help, others have this issue as well.

Try blowing on it and maybe cleaning with a qtip or one time I plugged my headphones in and no sound was coming out and I just restarted my phone and it worked again. Hope this helps
