unidentified serial number razer kraken x lite | Razer Insider
Skip to main content

I bought these headphones in a store and created a razer ID, but they didn’t put an activation code for 7.1 surround sound in the box. I tried to register the device in razer ID, I entered the product number, serial number, date of purchase (March 9) and when I pressed the button, it further wrote that the unidentified serial number, although I entered it exactly the same as on the left earphone, I even tried to change the zero to “O” , but no effect

Hi Tactic_Rot,

I understand that you’re having an issue registering your device serial number with your account to request a 7.1 Surround Sound activation code. You can use this link as a guide on how to check your device's serial number. If the same problem persists, PM me your device serial number so I can verify it in our system. Have a great day!
