The dimensions of the case are exactly the same as the first generation, but the weight goes up by 5 grams (50 g total). The first-generation AirPods Pro fit perfectly into the new case, but don’t think about doing this because then the association between the case and the headphones won’t work.However, it is quite easy to distinguish between the two generations of AirPods Pro. This is a solution that many third-party manufacturers had adopted on protective cases for AirPods and which Apple now adds directly to the case, which also acts as a charging station for the earphones. At the moment, Apple does not sell an official lanyard directly and, when asked during a briefing, a company representative told us that this is not in the pipeline, at least not any time soon. On the Apple Store, however, a compatible product is already on sale and many more are sure to arrive on Amazon and other online marketplaces.
