Resetting the AirPods Max, Apple's first over-ear headphones, is simple. First, make sure you charge them for a few minutes.
Then, just press and hold the noise control button and the Digital Crown until the LED flashes amber.
If you want to reset the AirPods Max to factory settings and unpair them from your iCloud account, do the same, but wait for the LED to change from flashing amber to white.
