As part of a wide update, Apple has issued new firmware revisions for AirPods, AirPods Max, AirPods Pro, Beats Solo Pro, Powerbeats 4, and Powerbeats Pro.
Expected in the update are Apple's standard performance improvements, and bug fixes. The update also brings support for Conversation Boost for the AirPods Pro.
Announced at Apple's worldwide Developers Conference in June, Conversation Boost leverages microphone beamforming and machine learning technology to isolate human voices. The feature is tuned to focus on a person speaking directly in front of a user, making it easier for AirPods Pro owners to listen during face-to-face conversations.
Conversation Boost can also filter out distracting ambient noise.
All devices get firmware version 4A400.
The new firmware is installed automatically for users, with no mechanism available to manually force an update. As long as AirPods or AirPods Pro are in a charging case and connected to an iOS device, the firmware will install by itself.
AirPods users can check the current firmware for their audio accessories within the Settings app, selecting General, then About, then select the relevant device from the menu.
