Apple today released new beta firmware updates for both AirPods 4 models and the AirPods Pro 2 with both Lightning and USB-C charging cases.

An Apple AirPods Pro 2 upgrade is the capability to use the earbuds as hearing aid. Changes in U.K. regulations mean Apple will upgrade the software imminently.

The H2 chip at the heart of these earbuds delivers twice the active noise cancellation power of the original AirPods Pro, making them significantly better at blocking out unwanted background noise. Whether you’re trying to focus in a busy office or find some peace during your commute, the difference is noticeable.
