Our Verdict
Apple AirPods Pro (2nd generation)
Apple AirPods 4
The Apple AirPods Pro (2nd generation) are better for most people than the Apple AirPods 4 mainly due their more predictable fit and the flexibility of active noise cancellation. On the other hand, if you prefer the environmental awareness of the open-back AirPods 4 and their looser fit, you may prefer that to the transparency mode on the AirPods Pro (2nd generation). Both have the H2 chip for switching between iCloud-registered Apple devices and Spatial Audio. However, the AirPods Pro (2nd generation) can also charge wirelessly, while the AirPods 4 only charge via USB-C.
