This is why Apple got rid of the headphone jack on the iPhone 7

Welcome to your hearable future. At the launch of the iPhone 7 yesterday, Apple announced that it was ditching the white headphone wires that have been an icon of the brand since 2003. Instead, listeners will use AirPods, a pair of wireless earbuds that connect to the phone over Bluetooth. Ditching the headphone jack allows the iPhone 7 to shrink even slimmer, and losing a hole makes the phone more water resistant. But this is also the latest case of Apple using its flagship product to bring a tech trend to the masses – get ready for "hearables" doing battle for the ownership of your ears.
