RGB headset lighting?

I bought the lioncast lx55 usb RGB gaming headset and according to the description you should be able to switch the RGB light on and off at the push of a button. But what doesn't work, what can that be? (Gamble on ps4)

Does it have an additional USB connector?

Because if so then it will only light up when it is plugged in and supplied with power.

Also had the problem

Thank you worked, now I just have to find out how I can change the audio and RGB via software.
