Headset Xbox?

I know the question is stupid, but: I ordered a headset (80EURO)

and then you can hear where the opponents come from? Probably, but a Youtube Rewiew that confused me (connect directly to the controller 3.5mm)

That depends on the headset. To hear where they come from you need at least Dolby Surround 5.1

But clearly with Xbox the cable comes into the controller.

Of course, even 7.1 has Thank you
