The USB connector is for power, not the audio source on a Windows 10 PC.
For a headset with an audio jack, everything works as described. The USB plug on the PC is only used to power the lighting. I don't expect a cable to last as long as there are kinks in it. The price corresponds to the quality.
Pros
RGB and more under control - H350 Pandora is the first Redragon headset with RGB lighting, dynamic and static RGB lighting modes can be easily switched with built-in audio controls , adjust the volume and mute the microphone.
