Did I get fake Airpods?

Hi, just baught a pair of Airpod 2 and everything seems fine at first. Then I noticed I couldn't shange any settings on them. After looking at the model number on each earbud it doesn't seem to match with what Apple has on their site.

Can someone please help me figure out if this is real ones or not?

The modelnumber is A1822 & A1623

I'm hoping this is a older numbering or maybe a display pair or something.

Big thank you in advance.
