Things do not go better with Coke at least not in this case. You may have done some damage to some circuitry on top of the stickiness on the button. Unfortunately it may need to be evaluated in a computer shop as it's impossible to do anything from here.

Remus Calinoiu wants answers to this question NO PC stated, so gets hyjacked anyway. if it is a PC and I see those are 32ohm 3.5mm phone plug electromagnet head phones. The problem is caused in this case by bad connection or the headphones shielded, wire 3.5plug is damaged If you try other phone (any) and it works ok,you know it is not the PC problem. buy $1 earbuds at a Dollar store and prove that, for $1 the other cause (I cant see you or it) if the head phone wires are long and land near a WALL wort transformer power pack it sure can hum. the cure is easy move the PACK away from phone lead in wire. even desk lamp power pack can do that.
