Help me fix my headphones!!!! very little voice. Any help?

My headphones have recently stopped working properly.  Everything seems to be in order but there is very little voice and it sounds very wobbly. The wires are all fine inside the headphones. Is this a problem with the speakers. Is there a fix or am i buying a new set soon?
