I recently bought a pair of HD800S from a seller off ebay for $1,480 and I'm skeptical that they are a legitimate authentic pair. I've seen numerous unboxing videos online so I was surprised when I first opened the box up. For starters, the headphones are placed in foam inserts rather than satin velvet material. Second, the imprinting on top of the head band is formatted differently from the ones I've seen online. And lastly, there is no Sennheiser branding on the 1/4" cables. The balanced cable that comes with it is also silver instead of black. I have attached photos below. Please let me know if I have an authentic pair or not. It sounds amazing btw, its just these other factors that have me concerned.
