Apple Explains Magic Behind AirPods 4 ANC Technology

The recently released AirPods 4 has introduced two models, one with Active Noise Cancellation (ANC), built-in speakers in the case, and wireless charge support. The other model lacks these functions but shares the same H2 audio chip and an improved design. What makes the model with ANC support unique is that it lacks ear tips, which most earbuds rely on to create a better active noise-cancelling experience.

How Apple Achieved ANC without Ear Tips

Apple’s Vice President of Hardware Engineering, Kate Bergeron, explained the magic surrounding the ANC feature without ear tips. She recalled a demo in 2021, where she and AirPods marketing director Eric Treski were blown away by the ANC feature without ear tips. Bergeron stated that acoustic and computational work is required for an effective ANC algorithm, and Apple had to put extra effort into these earbuds.

Key Factors in Achieving ANC

The H2 chip plays a crucial role in managing ANC quality and listening to environmental noise from the mics to cancel as much as possible. Eric Treski explained that the power of the H2 chip allows for great ANC quality in a non-ear-tip product. The earbuds also use computational power to manage ANC quality and listen to environmental noise.

Reviewers’ Verdict

Reviewers have praised the ANC feature in the AirPods 4, saying it works well when music or a podcast is turned on. However, if you’re looking for the best ANC on AirPods, Apple still recommends the AirPods Pro 2.
