Apple's quest for ever-thinner, ever-smarter devices may produce another casualty: your iPhone's headphone jack. A rumor at MacOtakara claims that the next iPhone might drop the 3.5mm port and use the Lightning port for audioinstead. The move would let Apple slim its phone even further (reportedly, over 1mm thinner than the iPhone 6s) and take advantage of Lightning's features, such as headphone-based DACs and app launching. You'd have to use an adapter for any conventional wired headphones, or else make the leap to Bluetooth.
