I did not know that they were counterfeit as they arrived. It first came to my notice when using a skincare item. People on the interwebs pointed out about spelling mistakes on the packet which tipped me off. Every item I have listed above was found to be counterfeit in retrospective. I got a usb voltmeter to test the charger. Had to use f3 to test the flash drives (should’ve done them in the first place) The headphones took the longest to figure out. It was a mid range sennheiser headphones which passed the authenticity check. It was a gift so I didn’t really test it immediately after purchase. 18 months later I gave them a try and they sounded off. Got them replaced by sennheiser and boom - massive difference in sound quality. I still wonder if somehow sennheiser was in on the scam because there product verification process told me that the headphones were authentic. I have drastically reduced my purchasing on Amazon ever since I figured out the scale of counterfeit items being sold. That said there is some stuff which I can only buy on Amazon so can’t really cut them off.
