AirPods Pro 2nd gen crackling/ interference

Hi all - I’ve had 3 sets of warranty replacement AirPods Pro 2 that have all developed a crackling noise in the right AirPod within days of getting them. The only way to stop this is by turning off noise cancelling which defeats the point slightly. I’m curious to know if anyone has had the same problem/ if there is a solution as Apple are now insisting that there’s nothing wrong with them as they are passing the diagnostics tests, despite my APP 1st gen never having this problem.
