The new AirPods 4 are equipped with new drivers and sound very similar to the AirPods Pro 2. The AirPods 4 may have slightly more pronounced vocal frequencies with the bass being a bit more powerful on the AirPods Pro 2’s seal design. Nevertheless, the difference isn’t substantial, and audio reproduction in both earbuds is great. Due to the open design of the AirPods 4, many users find these headphones very comfortable.
