Apple has extended the repair program validity on the AirPods Pro units that have issues with noise cancellation or static.
There are only two ways you can get your AirPods Pro repaired or replaced under this program:
if your AirPods Pro produces crackling or static sounds that increase in loud surroundings or
while working out or when talking on the phone – and – if the active noise-cancellation is not working the way it should, wherein it is affecting bass in the music or increasing background sounds, such as those of an aeroplane or a busy street.
“The AirPods Pro case is not affected and will not be replaced,” said Apple. In cases where the problem is not the ones Apple has noted, your repairs and replacements will work in accordance with the standard warranty period.
