Apple released new firmware for AirPods with two new functions

Apple’s new firmware 4A400 for the second-generation AirPods, AirPods Pro and AirPods Max brings two new functions to AirPods Pro and Max.

1. Precise search function; Previously, AirPods could only roughly locate AirPods based on the location of the last connection. The updated AirPods Pro/Max can be found as accurately as Airtag.

2. Dialogue enhancement function. Designed to help people with mild hearing impairment maintain closer contact in conversations.

After connecting the headset, open Settings>Accessibility Audio/Visual>Touch Headphone Adjustment, click Transparent Mode to turn on the dialog enhancement function.
