Interestingly, once MKBHD begins cycling through the iOS set-up process, he discovered a new step on iPhone 7 that focuses on the haptic feedback of the new Home Button. After confirming your language, region, and setting up Touch ID, Apple ID, and Siri, the iPhone 7 will allow you to "meet the new Home Button." The added process in iOS 10's start-up on the iPhone 7 and iPhone 7 Plus makes "your iPhone experience even more personal by choosing the click that's right for you."
Here, the iPhone will present you with three options of varying haptic feedback clicks. MKBHD described option one as "really light," almost to the point where he wasn't sure if he was pressing the button or not, three as "a really firm click response," and two as "a default, somewhere in the middle." He said with the middle option the "whole phone seems to be vibrating still," but he decided to go with the highly responsive third option to be sure when the button's been pressed.
Otherwise it seems like the contents of each iPhone 7 box, and the set-up process, are largely what's expected at this point from Apple. Each iPhone comes with the usual paperwork, Lightning cable, AC adapter, and now the new Lightning EarPods and
