AirPods’ fundamentals haven’t changed much in the eight years since they debuted. The stems are mercifully shorter, and they’ve gained some key features, but these have mostly been refinements to a product that entered the world fully formed.
Until last week, their upgrade cycle was straightforward: Apple introduces a new feature for its pricey high-end models, which filters down to the base level after a year or two. At last Monday’s iPhone 16 event, however, things got more complicated, as the base AirPods forked into two distinct products: AirPods 4 and AirPods 4 with Active Noise Cancellation.
