Apple has released new firmware for five AirPods models. Version 9B47 follows three rounds of testing since the end of September. Apple has not yet revealed what changes are included.
Apple has been distributing firmware 9B47 for AirPods Pro 2, AirPods Pro 3, AirPods 4, AirPods 5, and AirPods Max 2 since November 10th. It replaces versions 9A348 and 9A350. Apple released version 9A348 in September with features for iOS 27, while version 9A350 brought support for the AirPods 5.
Release notes are not yet available. Apple's support document for AirPods firmware updates still lists 9A348 and 9A350 as the current versions as of the evening of November 10th.
Key Facts at a Glance
- The new firmware 9B47 has been released for AirPods Pro 2, AirPods Pro 3, AirPods 4, AirPods 5 and AirPods Max 2.
- Apple tested the version in advance in three betas, on September 29, October 13 and November 3.
- Release notes are currently unavailable.

These AirPods will receive firmware version 9B47
| Model | Previous version | New version |
|---|---|---|
| AirPods Pro 3 | 9A348 | 9B47 |
| AirPods Pro 2 (USB-C and Lightning) | 9A348 | 9B47 |
| AirPods 5 | 9A350 | 9B47 |
| AirPods 4 (with and without Active Noise Cancellation) | 9A348 | 9B47 |
| AirPods Max 2 | 9A348 | 9B47 |
Older models such as AirPods Max with USB-C or Lightning, the first AirPods Pro, as well as AirPods 2 and 3, will remain on their previous versions.
Three betas since September
Apple had previously tested the new firmware in three betas: Build 9B5042a was released on September 29, Build 9B5043a on October 13, and Build 9B5045a on November 3. Apple did not release any release notes for these betas either.
The last version with new features was 9A348. It introduced the custom equalizer for AirPods, allowing separate adjustment of low, mid, and high frequencies, as well as the ability to connect AirPods Pro 3 to fitness equipment via GymKit. Support for AirPods 5 followed with version 9A350.
Check and install firmware
On an iPhone or iPad, the firmware version can be found under Settings > Bluetooth, then by tapping the Info button next to the AirPods, and then in the „About“ section at the bottom. On a Mac, you can find it under System Preferences > Bluetooth and then by tapping the Info button.
There's no dedicated update button. The AirPods automatically download the new firmware when they're plugged into a power source in their closed charging case, the AirPods Max 2 are connected via cable to the right earbud, and an iPhone, iPad, or Mac with Wi-Fi is within Bluetooth range. Apple recommends at least 30 minutes for this process. The step-by-step instructions for updating the AirPods firmware are available in the guide.
An update without any apparent reason
I expect 9B47 to contain bug fixes rather than new features. The updates between major release cycles have consistently been described in Apple's release notes as „bug fixes and other improvements,“ from 8B28 to 8B41.
Anyone experiencing problems with their AirPods, such as connection or battery issues, can use this update to check them. Those who are satisfied don't need to do anything; the installation will happen automatically.
Has firmware version 9B47 arrived on your AirPods yet – and do you notice a difference? Let us know in the comments which model you're using and what you notice after the update.
