The Lightning to 3.5mm Headphone Jack Adapter from Apple is the cable you would use to attach your analog, 3.5mm-outfitted headphones to an iOS device that only accepts an 8-pin lightning connection—a device like an iPhone 7, for example. Indeed, if you wanted a cable from Apple itself to connect your favorite pair of headphones sporting a stereo, 3.5mm mini plug to your iPhone 7 (or later), this would be the cable for you.
