Bump on this. I have the same issue but can't find any info that says that this model number belongs to a Square Wire 2.0. Are the ones that I have fake then?
That is great to know. I'm so used to those numbers that I didn't realize they weren't correlated. The Square Wire 2.0 is still on the arm and these seem to have the spring hinge.The number under the earsock is not a sku. It’s an Internal number for something else. SW2.0 didn’t have skus listed on the frame. They only had square wire 2 written on the inside of the right arm and it can rub off
