I have a question about the colour selection. My question is about the different product specifications between the black and white options. On the one hand, there is the wireless transmission, where the black option says "wireless connection" and the white option says "wifi". And there is also a difference in the audio connections: black: "Jack 3.5mm (1x), USB (1x)" and white: "Jack 3.5mm (1x)". Are the two variants identical and the specifications simply not quite complete/correct, or are the headsets really different?
