Perhaps your headphones are broken, terrible quality, or you had the volume too loud. I usually have my headphone out on about a third [10 o clock], and it does me fine. Turning a knob all the way up isn't a sign of quality. Just turn it up to a point where it doesn't distort, and is still loud enough for you to hear. If you can't turn it up loud enough to hear before it starts distorting, it's definitely one of the first 2 options.
