A year ago, Apple launched a repair programme for AirPods Pro that had problems with crackling sound, or with the noise-cancellation feature not working properly. Detailed in this support document, it addressed "crackling or static sounds that increase in loud environments, with exercise or while talking on the phone", and "Active Noise Cancellation not working as expected, such as a loss of bass sound, or an increase in background sounds, such as street or airplane noise".
Now Apple has decided to extend the programme for another year, 9to5Mac reports. When the programme started, Apple said it would cover affected AirPods Pro for two years after the device was sold. Now it's three years instead.
The AirPods Pro were originally released in 2019. Apple says the faulty units will have been manufactured before October 2020.
Users who experience their AirPods Pro crackling or noise cancellation not working as it should are advised to take them to an Apple Store or Apple Authorized Repairer. The headphones will be replaced free of charge.
