Airpods listed as "MV7N2LZ/A" model. 1st or 2nd generation?

Hi All. I found an Apple reseller selling Airpods listed as model "MV7N2LZ/A". Retailer doesn't detail if Airpods are 1st or 2nd generation.

I found other local resellers clearly specifying 2nd generation Airpods as model "MV7N2BE/A".

How can I be sure of which model I'm buying?

Thanks for your help.
