What is the difference between this headset, this one (https://www.digitec.ch/de/s1/product/corsair-void-elite-gaming-headset-12115794) and this one (https://www.digitec.ch/de/s1/product/corsair-void-rgb-elite-gaming-headset-12119141). They all look the same, only the red one has a cable in the picture and in the description. Is it a linking error that the red one appeared among the colour variants of this headset?
