Is there a huge difference in sound quality? I have never owned a beats phone, however I have owned beats earphones and they do sound good, (I use skullcandy fix ones now as they stay in, but thats beside the point) but would the beats engine inside these phones make the music we listen to it sound alot better regardless of the earphones? If so, do you think Apple will compete with this by including a better sound engine? (if that is such a thing).
