For those, like me, who weren't familiar with this feature, it was a partial noise cancellation on the receiving end. It was designed to help you hear the phone call better by suppressing ambient noise. As I understand it, the phone still has the same number of microphones, so it isn't due to a limitation that way. I wonder if it uses a dedicated noise cancellation chip that wasn't available in sufficient quantity, or maybe Apple is just wanting to push people towards airpod pros?
