Apple has sent over the air updates of the latest version of firmware to AirPods Pro and AirPods 2. The firmware version is 2C54. This version is common for both the devices, a change from the previous arrangement where there were two different versions of firmware behind them. While 2A364 was the firmware version on the AirPods 2, 2B588 used to be running the AirPods Pro.
How to Check if Your Device Has the Updated Firmware?
These are not your average devices with a display. You cannot find out if your AirPods are running on the latest firmware. The only way is for you to pair them to an iOS device. You need to place the AirPods (whether AirPods 2 or AirPods Pro) inside their cases and connect them to a power source as you would do for charging them. You should then pair them to an iOS device, an iPhone or an iPad. Leaving some time to lapse, check if the pairing has been done. Head to Settings on the device and then tap General. Next, tap About. In the options available, choose AirPods. You will find the firmware version mentioned against it. Check if it is 2C54. You can continue using the AirPods.
Apple Does Not Share the Details
Firmware updates are usually accompanied by a brief description of what is changing. Apple, however, does not provide such information. If you had identified certain issues while using the AirPods earlier and now you find they are no longer there, you have to understand that Apple has fixed them. There are such reports from users. Someone has said the battery life has improved by 3 hours.
As indicated, these are over the air updates and there is nothing you can do to download or install them.
