Apple Ships New AirPods Firmware 9B47 to Pro 2, Pro 3, AirPods 4, 5 and Max 2

Apple has started distributing a fresh firmware build for a wide spread of its wireless earbuds and headphones. The new build number is 9B47, and it replaces the earlier 9A348 and 9A350 builds that some models were running. Reports say the software had been in beta testing for several weeks before this wider rollout.

Which AirPods get build 9B47

According to the reports, the firmware covers five product lines:

• AirPods Pro 2
• AirPods Pro 3
• AirPods 4
• AirPods 5
• AirPods Max 2

One report notes the rollout is aimed at H2-equipped AirPods models and that availability is currently limited to select models, though a wider release is expected. AirPods Pro 3 owners are among those covered.

What is inside the update

Apple has not published lengthy release notes. A support document cited in the coverage states only that the firmware contains bug fixes and other improvements. More detail may be added to Apple's release notes page later, and anything more substantial will become clear only once users notice changes.

There is no update button to press

Unlike an iPhone, AirPods firmware cannot be installed on demand. The process runs automatically in the background once the buds are paired with an Apple device and connected to power. Because there is no software update option for these accessories, installation can take a few hours to complete.

To give the update the best chance of arriving quickly, Apple's own instructions call for keeping the AirPods connected to an Apple device and plugged into a charger, then leaving them paired and nearby while the firmware downloads and installs itself.

Why it matters for buyers

Firmware refreshes of this kind rarely add headline features; the focus here appears to be stability and small refinements rather than new capabilities. For anyone using AirPods Pro 2, Pro 3, AirPods 4, AirPods 5 or AirPods Max 2, the practical step is simply to keep the buds charged and connected so the 9B47 build can land on its own.
