Apple has determined that a small percentage of AirPods Pro may experience sound issues. Affected units were manufactured before October 2020.
An affected AirPods Pro may exhibit one or more of the following behaviors:
Crackling or static sounds that increase in loud environments, with exercise or while talking on the phone
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
Apple or an Apple Authorized Service Provider will service the affected AirPods Pro (left, right or both), free of charge.
Note: No other AirPods models are part of this program
Choose one of the service options below to have your AirPods Pro serviced. Your AirPods Pro will be examined prior to any service to verify that they are eligible for this program.

In the Activity Monitor app on your Mac, click Memory (or use the Touch Bar) to see the following in the bottom of the window:
Memory Pressure: Graphically represents how efficiently your memory is serving your processing needs.
Memory pressure is determined by the amount of free memory, swap rate, wired memory, and file cached memory.
Physical Memory: The amount of RAM installed.
Memory Used: The amount of RAM being used. To the right, you can see where the memory is allocated.
App Memory: The amount of memory being used by apps.
Wired Memory: Memory required by the system to operate. This memory can’t be cached and must stay in RAM, so it’s not available to other apps.
Compressed: The amount of memory that has been compressed to make more RAM available.
When your computer approaches its maximum memory capacity, inactive apps in memory are compressed, making more memory available to active apps. Select the Compressed Memory column, then look in the VM Compressed column for each app to see the amount of memory being compressed for that app.
Cached Files: The size of files cached by the system into unused memory to improve performance.
Until this memory is overwritten, it remains cached, so it can help improve performance when you reopen the app.
Swap Used: The amount of space being used on your startup disk to swap unused files to and from RAM.
To display more columns, choose View > Columns, then choose the columns you want to show.
If memory pressure is yellow, red, or has spikes, check to see if an app is using up memory and causing the memory pressure to increase. If you no longer need to have the app running, you should quit the app.
