At 8 o'clock this morning, the first batch of AirPods Pro 2 TWS headphones officially started shipping, and Apple also updated the headphone support document, which explains why the second generation is incompatible with the earbuds of the first generation products.

According to the support document, the earbuds of the AirPods Pro series are designed according to the corresponding products, which makes the earbuds of the first generation AirPods Pro have relatively dense mesh. Using them directly on AirPods Pro 2 may cause acoustic differences.

Therefore, Apple recommends that users use the earbuds that come with the AirPods Pro 2 instead of continuing to use the earbuds from the original AirPods Pro.
However, it should be noted that although Apple said that the two generations of earbuds are incompatible, in fact, the structure at the connection between the two generations of earbuds is completely consistent, which means that they are still compatible in a physical sense.
Therefore, if earplugs are lost, users can theoretically still use the earplugs of the first generation AirPods Pro to respond to emergency response.
Of course, if you lose the newly added XS earbuds, you really have to choose to buy another new one.
