Before the 4.3 update, the Apple Support iOS app only provided a generic AirPods menu option if you needed support or to report loss or damage. Now the app is able to display your specific AirPods (after they’ve been paired), and can provide detailed device information.
This means you won't have to dig through a generic AirPods menu or Bluetooth settings to find your particular model. Now you can pull up warranty info directly in the Apple Support app, making it much easier to look up information or report an issue.
This is particularly important in the event that you run into trouble with your AirPods, as servicing will be free so long as it’s within the first year of purchase. Though the One Year Limited Warranty only covers defects, not wear through normal use.
