Is Razer Electra V2 compatible with 7.1 SURROUND SOUND
I purchased the headset, downloaded the program, registered the product in the account, and did not get an activation code to run the program with the headset
Hello everyone! Thanks for posting your concern on our support board. Have you received an activation card in your Razer device's package? Please be aware that the
7.1 Surround Sound is only compatible with Razer Kraken 2019 and Kraken X. Otherwise, you should be using the Razer Surround Sound/Surround Sound Pro for all the headsets that are part of the legacy devices

Feel free to send me the email email address associated to your Razer ID via
PM so I can check your device registration and verify the code.
i have a Kraken razer with code (*Omitted), its activation code only has 15 digits and to use the surround program they ask you for a code with 20 digits. I add that my product has already been registered 6 months ago and I have never received an activation code to the email. Help me
