I knew they were "updated" but didn't expect earwax and oil to still stick to the headphones. I thought they were deleted in the "upgrade" process, but I think it was just overlooked or not done at all. That explains the scratches and other marks on the surface of the headphones. Finally, the battery is 80% short as the seller claims. I was lucky enough to get 7 hours on the battery. They go from high battery to medium battery in about an hour.
