Not sure if there's any difference at all, outside of the packaging + wall charger. I'm pretty sure Apple will honour the warranty regardless of the packaging. My friend and I both got the white box version, but I'm fine with getting the newer packaging and not getting the wall charger. Does yours have the Apple warranty card?
Say what you will about the Beats brand/pricing/sound quality (including myself, a long time hater), but a brand-name, wireless, noise cancelling headphone with Apple support and decent sound quality at $100 is a steal. I'm pretty sure most of us can sell this used, in a year, for at least what we paid for it.
