After watchOS 9.0.1 for the Apple Watch Ultra, Apple has released a new firmware update for AirPods Pro 2. Both of these devices will be available starting tomorrow, which means users will have day one updates to install once they get their hands on these products. Here’s what you need to know.

AirPods Pro 2 firmware’s new version is 5.0, build 5A377. As of right now, Apple has not disclosed what’s changing with this firmware. For the Apple Watch Ultra, however, we know that the Cupertino company is fixing an audio issue with the microphones available on the device.

For the AirPods Pro 2, Apple is likely doing something similar. More interestingly, the company is also testing a firmware update for AirPods Max, which has not currently been made available for users. In this firmware, a developer was able to discover that Apple is readying a new audio codec to improve calls on the premium headphones.

In addition, this beta firmware made us believe that Apple could be readying Lossless support for AirPods Pro 2 as it would need Bluetooth 5.2 to support the new LC3 standard (this device offers Bluetooth 5.3). As previously reported:

While the LC3 codec will improve audio calls, efficiency, and stability of Bluetooth devices, the requirements to take full advantage of this standard will require Bluetooth 5.2.

(…) In addition, 9to5Mac already found references on iOS 16 that it will support LC3 codec and low-energy Audio support. For the LE Audio support, it’s worth mentioning that a senior Apple engineer is heavily involved in this new standard.

(…) With Bluetooth 5.2 and LC3 support, Apple will be able to get rid of AirPods desynchronizing when on the user’s ears, and improve battery life thanks to the low-energy standard, while focusing on efficiency and stability.

It’s not clear when Apple will take advantage of it. For example, the new Apple TV 4K could support a 120Hz refresh rate, but Apple hasn’t implemented this feature yet.

How to install AirPods Pro 2 new firmware

As you probably know by now, Apple also does not make it easy to manually update your AirPods Pro 2 to new firmware versions. Instead, the company said new firmware versions will install when the AirPods are connected via Bluetooth to your iPhone.

To check your AirPods firmware version:

  • Open the Settings app on your iPhone
  • Navigate to the “Bluetooth” menu
  • Find your AirPods in the list of devices
  • Tap the “i” next to them
  • Look at the “Firmware Version” number
