So, I've recently been considering upgrading my headphones (I currently have what I perceive to be a "good but not great" set of Skullcandy cans). I am very noobish in this subject area and was looking specifically for someone to detail the difference between "over-ear" and "around-ear" headphones. Yes, I know what they look like, but I was wondering if there was a difference in the audio quality, or the "sound" of the headphones. I haven't really been able to ascertain anything other than "around-ears close off sound."
