Hello everyone, I found an ad on the Internet for the sale of these headphones for a good price, a lot of positive reviews, everything is fine. But there is one problem, I noticed that in the photos of these reviews, another grid is visible, it is slightly recessed into the headphone case. At the same time, the seller writes that these headphones come with two versions of this grid and both versions are original, please tell me if there are really two versions of these headphones???
