If you really care about audio quality, you should be pretty excited about headphones that can draw power from the lightning connecter... that allows for better processing, better noise cancellation, and so on all for headphones that never need a battery.
That's something that couldn't happen if Apple stuck with audio jacks.
This doesn't make sense. The DAC is the most important component of digital audio quality. Moving it to the headphones does none of these things (digital processing is still in the phone) and takes the control of audio quality entirely out of Apple's hands. This seems counter to their general philosophy.
As for the wireless part, it seems like Apple is trying to make that as nice as possible, with as high a quality as possible. That too is better if you care about audio at all.
So why so down on such an obvious improvement that helps wired AND wireless users?
This also doesn't make sense. Bluetooth compression is known for reducing audio quality, even if you ignore the various reported connectivity issues.
Replacing an old standard without an improved solution (even if proprietary) is very unlike Apple. My only conclusion is this is a money grab. It shows them struggling to differentiate themselves in the market. I think they may have jumped the shark.
