I agree that using some other format instead of Bluetooth would have been nice but for the purpose it's designed for it's unnecessary. Using this with compressed streaming from Apple Music or Spotify it's just not going to help even if it's wired. If you're listening from something like Tidal at that point then you would have to upgrade the drivers and everything else so $550 becomes $1550. Yes there is a difference when you spend that much for headphones if you can hear it. These aren't meant for audiophiles but rather just someone who wants good sound for streaming music.No I mean those are great don’t get me wrong, but I would have hoped for something more substantial such as a better delivery option (as opposed to the compression of Bluetooth). And yea the competitors do have their own spatial audio options. Also putting a lightning port on them was a painful reminder of apples insistence on not transitioning to usb-c.
As to Lightning vs USB-C, I can't see how that would improve them. For most people with iPhones it would actually be a negative because many don't have USB-C cords but all have Lightning cables. Now if Apple was trying to market these to the Android community then perhaps that would have been a good choice.
