Apple cofounder Steve Wozniak recently said removing the headphone jack in the next version of the iPhone is going to “tick off a lot of people.” It’s been rumored for months that Apple would be scrapping the 3.5 mm headphone jack in the iPhone 7 expected next week. Such a move could upset users who have invested in listening technology that uses the jack, Wozniak said. Ditching the headphone jack could be the prelude to another rumored new product: Bluetooth earbuds based on a very-low-powered radio chip developed exclusively by Apple.
