Apple AirPods 4: everything you need to know before upgrading from 3rd generation
While the 3rd generation AirPods refined the previous design, the AirPods 4 sport an open-ear design for a more comfortable fit across a broader range of ear shapes. Both 4th generation models have a shorter stem housing the battery and chip, an easier-to-use force sensor, and a built-in vent system for improved sound quality and comfort.
