1.You can also check the miniplug on your headphone. It could have been damaged when you pulled your headphone. The input plug commonly have rings that could bend and ths affect the connection or sound quality. You can DIY replace the input plug or buy a new headphone instead. 2.Try to use other headphone if it will work, to check if the problem is on your headphone input plug, or the headphone jack. Cheers.
