Apple executive Greg Joswiak stated in the Let us loop you in event (held at the Town Hall auditorium in the Apple Campus) on March 21, 2016, that they sold over 30 million 4-inch iPhones in 2015, further explaining that some people love smaller compact phones. Later in the event, he announced the iPhone SE, describing it as "the most powerful four-inch phone ever." With a total mass of 113 grams (or 4.0 ounces), iPhone SE is one of the lightest iPhone models released, only surpassed by iPhone 5 and 5S (both having a total mass of 112 grams or 3.95 ounces). The iPhone SE, iPhone 6S, and iPhone 6S Plus were the last iPhone models to feature a standard 3.5 mm stereo headphone jack.
