    Today I received my new Hammerhead Pro v2 headphones and I am struggling with registration of them on Razer website. When I am putting the serial number of my product in the registration then the info comes out
    " Error:Item Serial Number Is Unknown". Also i tried different variances of serial number with "0" and "O" but it still don't work.

    Any help appreciated.

    You have headphones from official razer store of razer reseller ? If not i can only recommend you to contact support via chat and ask them to cheack it but from your description i dont think it's a mistake in serial code.

    Hey there,

    When you typed in the Serial number from the hammerhead, can you recheck and make sure its taken from the "S/N" and not the "Product no".

    Also do check and make sure you are inputting the S/N and Product no. details for the correct product under Razer ID site. Because it happened to here and then i clicked on the wrong product and later when i saw that same error message i realized it was in the wrong product page.

    Maybe, let us know.
