As far as Apple is concerned, the headphone jack is extinct.

Apple announced the iPhone XS, XS Max and XR at its event on Wednesday. With the new iPhones coming in, Apple has stopped selling the iPhone 6 and 6 Plus, iPhone 6S and 6S Plus and iPhone SE -- meaning that the last iPhones to come with a headphone jack are gone.
