According to Barclays research analysts, Apple could decide to add a second speaker in place of the 3.5mm headphone jack on the iPhone 7.
AppleInsider has managed to get their hands on a Barclays research memo that reveals this info. Apple will reportedly be using a second amp to power the second speaker, sourced from Cirrus Logic. The report also suggests the iPhone 7 may not feature dynamic noise cancellation. Instead, Apple is likely to introduce the feature with the “iPhone 7s” in 2017.
Confirming previous reports of the iPhone 7 ditching the 3.5mm headphone jack, Barclays research analysts believe the smartphone will ship with Lightning-equipped headphones. With more and more reports claiming the same thing, it is does seem like Apple will indeed be axing the 3.5mm jack from the iPhone 7 in order to make it thinner.
