cómo se si mis airpods son verdaderos

al conectar mis airpods por primera vez me decía “no se puede verificar si estos audífonos son unos airpods originales y es posible que no funcionen de la forma esperada” que significa esto? son originales?

when i plugged in my airpods for the first time it said "these headphones cannot be verified as original airpods and may not work as expected" what does this mean? are they original?
