This time, the AirPods 4 case has gotten even smaller in size, and has switched to USB-C charging, making things much easier. The case for the noise-cancelling version also comes with a tiny charging speaker, which represents a large step, a find my airpods feature, and wireless charging but also includes a wireless speaker for charging sounds and, finding lost Airpods. What did change was that the casing is smaller than the previous one so it will not support MagSafe any longer. The strap system keeping the Airpods inside the case feels a bit stronger but annoying, unlike before, you can still use the normal Apple watch puck chargers. In addition to this, there is nothing in the form of a physical button available for pairing, as this has been superseded with a touch sensor which has other functions too.
