The loss of the 3.5mm headphone jack was a huge disappointment for many, and it’s only getting worse with this new generation! There is no audio port on any model released so far – not even an extra one like what they had in previous iPhones or iPads where you could plug something else into there instead if your regular ones stopped working properly (which happens).
iPhone users can enjoy a wired connection with their headphones by using the Lightning to 3.5 mm headphone jack adaptor, otherwise they will need wireless Bluetooth connected devices for listening audio on all current models of iPhones
