I have verified that the Razer BlackShark V2 X serial number is already link to a different Razer account. I suggest taht you reached out to the reseller and take advantage of your warranty. Please note that Razer products purchased from non-authorized dealers may be used, counterfeit, re-boxed, defective, or gray market goods. You can check the list of authorized Razer resellers to ensure your Razer device is genuine. Ig you need help in the future, feel free to send me a PM me. Take care for now!
