Apple continues to improve its TWS headphones by releasing a new version of the software, MacRumors writes.
This time, the update was released for AirPods Pro 2 (Lightning/USB-C) and AirPods 4. The system received the numbers 7B21 and 7B20, respectively. Both models were previously shipped with 7B19 firmware.
Apple reports that the update contains "bug fixes and other improvements." Unfortunately, there are no other details about the system.
As a reminder, Apple does not have the ability to update AirPods software manually, but the firmware is usually installed on the device over the air when the AirPods are in the charging case and connected to an iPhone or Mac.
