Powerbeats Pro True Wireless Headphones Serial Number question

[foley7]

I purchased a used Powerbeats Pro True Wireless Headphones from a reputable vendor on eBay. Everything checks out that they are legit. I verified the Serial Number with apple through chat last night. The box and wireless charging case have legit SN. However the left and right earpieces each have a different SN from the case and from each other. Apple claims that the serial number on the case is the only SN they track. Can someone who bought these new from Apple, Bestbuy, etc see if all 4 of the SN on the product match? I scoured the web and most say that their SN do not match but i was hoping to get confirmation here. I'm trying to determine if they are counterfeit.

No matching here, purchased new from Best Buy around launch time

Thanks. That’s what I suspected
