Apple today released new firmware for its AirPods Pro 2 and AirPods 4 wireless earbuds. The new AirPods Pro 2 firmware has a build number of 7B20, while the new AirPods 4 firmware has a build number of 7B21. The AirPods Pro 2 firmware is for both Lightning and USB-C charging cases.
Apple says firmware versions 7B20 and 7B21 include “bug fixes and other improvements.” No further details were provided.
While Apple doesn’t offer a way to manually upgrade AirPods firmware, but it is generally installed over-the-air when the AirPods are in a charging case and connected via Bluetooth to an iOS device or Mac.
If you place the AirPods Pro 2 or AirPods 4 in their case, connect them to a power source, and then pair them to an iPhone or iPad, they should update after a short period of time.
