That Apple wants their users to only use 'approved' peripherals with their stuff (i.e. only those from which they get a share of the profits) under the guise of 'user experience' and 'convenience' does not mean the rest of the world will suddenly give up on their analogue headphones. Apple users will be able to buy dongles (which have to be Apple-approved, so Apple will still get their share of the profits leading to higher prices which Apple-users are willing to bear to be part of that exclusive community) to connect their analogue headphones, the rest of the world will happily keep plugging those 3.5mm jacks into their phones and tablets and radios and other devices.

As an aside, what a strange creature is man that he wants to replace a device which is analogue by nature - ears not being digital after all - with a digital counterpart which is clearly sub-optimal, overly complex and fraught with potential restrictions. Meanwhile that same man will brag to his friends about the analogue turn table he purchased on which he plays his analogue records for that true analogue experience, claiming a much warmer sound that is clearly superior to that produced by digital players which 'chop the sound into bits which takes away from the experience'.

Bizarre, but profitable.
