My Razer Blackshark V2s are playing white noise, but only when sound effects are played. For example, when you change the volume on Windows and it plays the sound effect, there's static that plays there. I have system volume turned up to 100, and I can only hear the white noise when I turn up the volume on my headphones to a certain point. When I tried using the Blackshark on different devices, the static was absent. I don't have any external dac or amp, and I'm not using the sound card that comes included with the headset. When I tried using the sound card, the static was still there. I also tried a different pair of headphones on my pc, and the static was present in those as well. Will an external dac/amp fix this?
