Thanks to the significant upgrade to the H2 chip, the AirPods Pro 2 now boast twice the Active Noise Cancellation effectiveness as the originals. The Spatial Audio (with dynamic head tracking) has been improved, with a personalised profile fit for each ear. This is coupled with a low distortion driver and custom amplifier for “more detail and clarity across a wider range of frequencies”. The addition of a pair of XS silicone ear tips should also improve passive noise cancelling for smaller ears.
