Finding the latest 2019 AirPods 2 on online can be troublesome, because they are officially called AirPods, just like the 2016 AirPods 1. And they also look the same or at least almost the same.
Have a hard time finding to buy the 2019 Apple AirPods 2 on online stores in the US? Don’t want to mix them up with the older ones, since the stores still sell them? Look for the MRXJ2AM/A and MV7N2AM/A SKUs. The MRXJ2AM/A is the SKU of the 2019 AirPods 2 with wireless charging case ($199), whereas the MV7N2AM/A is the SKU of the 2019 AirPods 2 with the regular wired-only charging case ($159).
As for the AirPods 2 on the Apple online store, the situation is easier, because the store has simply replaced the product page of the older and discontinued AirPods with the product page of the new ones.
Besides the MRXJ2AM/A and MV7N2AM/A, a new SKU in the AirPods lineup is the MR8U2AM/A. That’s the SKU of the wireless charging case only, without the earphones. The case is priced at $79.
