Several pictures and a video of a Lightning to 3.5 mm adapter obtained from a Foxconn factory in Vietnam have leaked online via Tinhte.vn.
Apple seems to be planning to replace the usual audio jack with a Lightning connector.
A notable aspect in the video is that the new jack adapter displays an error when it connects to a device running iOS 9, but it works perfectly on devices with a beta of iOS 10.
Given these new changes, it will be impossible to listen to music and charge the device at the same time.
A recent leak claims that the Apple keynote will take place September 6 and pre-orders will start three days later.
