The QC20 have been amazing, and have longer than apple's 5 hours battery life. The wireless QC20 will be out soon, and they're rated at 10 hours I think (maybe 8, can't find the article now).

I don't suspect they'll be able to do wireless active noise cancelling, so the argument for the lightning port supporting active noise cancelling functionality is weird... do you want people to go wireless, or not? My first reaction is that that was a poor justification.
