You can use both devices, the Razer BlackShark V2 HyperSpeed and the Razer Viper v3 Pro, via separate receivers. The BlackShark V2 HyperSpeed uses a 2.4 GHz wireless receiver, while the Viper v3 Pro also has its own 2.4 GHz receiver. Both devices can be used simultaneously as long as you have enough USB ports for the receivers. You do not need to connect them wired unless you prefer a wired connection for the BlackShark V2 HyperSpeed.
