I have tried to shut it down a couple times , and take out my headphones and put it back it but it won't work. Plz help!!! btw- I have an IPhone 4s if that makes a difference to the answer.
I don't know. Are you logged in to Music? Is the phone muted? Did you check the volume buttons? Are your headphones of the wired or Bluetooth variety? Have you tried rebooting your iPhone or resetting all settings?
