Apple's upcoming fall event on September 9 is expected to unveil significant updates to its AirPods lineup, including the AirPods Pro 3 and AirPods 4. The AirPods Pro 3 are rumored to feature enhanced digital active noise cancellation (ANC) primarily through software improvements and advanced audio processing techniques. Meanwhile, the AirPods 4 will reportedly offer a revised design, enhanced sound quality, and possibly ANC for the first time in a mid-tier model. Additionally, minor revisions are anticipated for the AirPods Max, including a switch to a USB-C charging port and new color options, but major updates like the H2 chip are not expected until a potential future release. These updates reflect Apple's continued focus on audio innovations, following the commercial success of its previous AirPods models.
