As an owner of 3 mid-range headphones (Denon AHD-2000, Denon AH-MM400 and Sennheiser HD-25-II) I'm kinda miffed, sure there's an adapter, sure the jack is obsolete (debatable), sure wireless is the way to go (but 4 hours autonomy is no improvement over anything), but I feel this "push forward" is unwarranted:
1. Lightning headphones require an external dac (in the cable/plug) if I'm correct?
2. Wireless headphones need charging, this is a con in my book, regardless of future iterations that will improve on this issue by lasting longer.
3. Bluetooth headphones and speakers have teething problems that are not yet fully solved and while I admire the engineering and craftsmanship that went into the AirPods, the drawbacks are still quite there (4 hours autonomy, still relying on Bluetooth 4.2, no AptX support).
I may be an old geezer but this transition is going to be felt deeply, will the audio industry align to Apple's decision? Bluetooth is not superior in terms of quality as it is now (Apple's "secret sauce" notwithstanding) and Lightning is not an industry standard in terms of audio (yet), maybe USB-C will.
