Counterfeit? Fake? Shure SM58 (SM58S) Grey Box (China) vs Green Box (Mexico) Microphone Comparison

I called Shure today and they told me they have never made this microphone in China except for sales outside of the USA. However, there is a california sticker on this one.... There is also not much info out there about grey box vs green box, but here I do unboxing on both and do a sound quality comparison as well. So is this a fake? If so, its even better than the one recently reported here:    • This Fake Microphone Almost Fooled Me - Wa...   (Dark Corner Studios) Sorry about the issues with focusing my old camera: Canon VIXIA HF M40 Canon WD-H43 43mm 0.7x Wide Angle Converter Lens
