LIghtning is needed if you play high res Audio, I presume, that's where Apple is heading.
LIghtning allows for higher density signal and probably much higher quality. Even if you use wireless phones, I bet that the sound will be better than current one.
Seriously? Did you just make up that BS now or does it take special effort to come up with something so stupid?
So the magic lightning copper is able to carry a higher density signal than the plain old copper in normal earphones. What the hell does "higher density" even mean when you're talking about a signal over copper? What were you smoking when you came up with that?
It's an analog signal over copper.
