What did you learn from this experience? Hopefully it’s to stay away from Beats… (I’m just kidding…sort of…) Don’t know where you live but where I’m from, fakes are readily available at local flea markets. They sell them for $50-$75 and a lot of our high school kids around town have them. I teach at one of the high schools and was asked if I wanted a pair. I told the student that I wanted to hear them first. When they brought them to me, the box looks legit and then you take out the headphones and they are almost up to par. Sound was atrocious, even worse than the real Beats…What surprised me was I scanned the upc on the box, with my smartphone it was able to find them and pick up the barcode. All in all, like wje said, I would not be surprised if this serial # has been used by some counterfeiters. If you got them from a reputable dealer, and have your receipt it’s your call if you want to return them.
