Apple Unveils Firmware 6F21 for Older AirPods Models

The update likely includes minor improvements and bug fixes, while new hearing features for AirPods Pro 2 debut in limited regions.

Apple has released firmware version 6F21 for the original AirPods Pro, AirPods 2, AirPods 3, and AirPods Max with Lightning connector.
The firmware update is expected to focus on bug fixes and minor enhancements for these older AirPods models.
Apple's new hearing health features for AirPods Pro 2, launching with iOS 18.1, will initially be available only in the US and Canada.
The new hearing capabilities, including hearing tests and hearing aid functionality, require FDA authorization, which Apple has obtained in the US.
iOS 18.1, set to release on October 28, will introduce these advanced hearing features alongside Apple's first Apple Intelligence capabilities.
