This^ I appreciate the 3.5 Jack, but it will be deleted by the iPhone 7 or the 2017 iPhone. It's days are numbered and it makes sense. With the Jack being deleted, it allows for a possible larger battery or wireless charging.
Bluetooth is finally becoming the universal and with Bluetooth 5 on the cusp, it's logical at this point. If Apple does delete the Jack, will they provide an adapter? Will Apple provide the option for the user for a quality set of Bluetooth EarPods in the box? I think everyone knows it will be deleted, but how will Apple address and remedy the alteration? What the costs are is another question.
