But we'll get Apple headphones compatible with new port/or wireless so I don't care that much since they bundle quality headphones with their devices

Well I expect them to release wireless headphones included in each Iphone purchase... Otherwise bye bye Apple

I think its just another way for people to have to buy iPhone official earphones. Unless they have special Bluetooth earphones but I doubt it.

It is rumored to come with wireless Bluetooth ear buds and there would obviously be an adapter for it so you can use your existing headphones. So yes.

Yes if they came with Bluetooth headphones/earphones

no

Yes. This is one of those things that you don't realize how lucky you are until you can't have it.

I have a really awkward condition which makes it so that when I wear headphones/earbuds (other things too but this is one), my body will spasm uncontrollably and it'll be very painful.
