Help with Razer BlackShark V2 X – Serial Number Partially Worn Off & Missing 7.1 Surround Sound Code The problem is that on my Razer BlackShark V2 X, the serial number behind the ear cushions has been partially worn off. I can see the first 10 characters, but the last 5 are completely unreadable, no matter how hard I try. Because of that, I can’t identify the full serial number. Also, the scratch code for the 7.1 Surround Sound activation is missing from the box. However, I do have the original receipt, the box itself, and everything else that came with the headphones.Is there any way to retrieve the 7.1 Surround Sound code in this situation?I bought it from an official seller.
