Beats Buyers + Lightningbolt Headphones

I just read this article on the Verge about how Apple might be producing headphones that exclusively use the Lightningbolt port.

The idea got me pondering some questions--and not necessarily good questions, mind you. I'm pretty naive when it comes to stuff like this.

1. Are mp3s the most commonly purchased audio format on iTunes?

2. Has Apple's decision to omit FLAC playback in iTunes had an effect on the spread of FLAC files? How about high-quality audio in general?

3. Has the popularity of the iPod and iPhone, and by extension, mp3s, conditioned the majority of Apple consumers to be content with low-quality audio?

4. Do Beats consumers associate Beats headphones with high-quality audio or listening experiences?

5. Do Beats consumers primarily listen to their music via mp3s on 'iDevices', like iPods and iPhones purchased through iTunes?

6. Do Beats consumers know that Apple owns Beats now? Is advertising that fact beneficial to Apple?

7. Does Apple have or could Apple create a high-definition audio department in iTunes? If they don't have one, why don't they have one?

8. If Apple began aggressively selling high-definition audio on iTunes in conjunction with the release of a new set of headphones, bolstered by the Beats brand, that exclusively used the Lightningbolt port, would Beats consumers credit Apple and said headphones with a revolution in hi-def audio? Would that significantly strengthen brand loyalty among Apple's music listeners?

9. Would that effectively allow Apple to sell a "better than Beats headphone," at a premium, that's produced at the cost of Beats headphones (maybe even less with Apple's manufacturer connections?), by introducing Beats consumers, who have been conditioned by low-quality mp3s, to high-definition audio, all while achieving "consumer lock-in", via Lightningbolt?

Again, I'm not pretending to know the answers to these questions, and yes, phrases like "Beats consumers" and "Apple consumers" are vague at best, but I was hoping to get help thinking through these questions and to stimulate conversation on the matter.
