Pressure Relief System

Since the new AirPods are expected to fit more tightly within your ears for better sound, they’re going to need to borrow another innovation from the AirPods Pro, with vents to equalize pressure within the ear.

This hasn’t been a problem with current AirPods, since they don’t really create a pressure seal for most users. Some with smaller ears do find that they’re uncomfortable to wear for longer periods of time. Pressure relief vents should help fix that across the board.
