A new video posted today on Vietnamese site tinhte.vn (via 9to5Mac) demonstrates what appears to be an official Apple Lightning to 3.5mm headphone adapter that will likely ship with the new iPhone coming this fall. The adapter, which features a design reminiscent of Apple’s previous Lightning accessory adapters, appears to be between 2.5” and 3” in length and includes a male Lightning connector on one end and a female 3.5mm headphone jack on the other. The post accompanying the video claims the adapter was picked up from a Foxconn Apple supplier factory in Vietnam, and that the adapter only works with devices running iOS 10 beta, not iOS 9; when used with a current iPhone model — one that actually has a headphone jack — audio is sent to the Lightning port rather than the built-in headphone jack.
Rumors the Apple would drop the headphone jack from the next-generation iPhone began circulating as far back as last November, gaining support as more analysts weighed in and more recently leaked photos and videos appeared to show prototype units lacking the 3.5mm headphone jack found on the bottom of prior devices. While a few leaked images of Lightning EarPods have surfaced in recent weeks, a research note from Deutsche Bank claimed last week that Apple would include a Lightning adapter in the box, rather than a set of Lightning EarPods.
