The Razer BlackShark V2 X (RZ04-0324) is bundled with the 7.1 Surround Sound scratch card, while the Razer Blackshark V2 X USB (RZ04-0457) should get the 7.1 Surround Sound code after its product registration via email. On the other hand, the THX Spatial Audio is a stand-alone fee-based app. I recommend visiting our 7.1 Surround Sound Activation Support here so you can request an activation code. I’ll be locking the thread now. Feel free to send me a ping should you need additional assistance.
