Why is there only noise or nothing at all in voice chat ON THE NINTENDO SWITCH in Fortnite with my headphones (see picture)?

I really want to use the voice chat on the switch, but it doesn't work with my 4 pieces, neither the normal ones with MIKRO nor the headset.

Maybe you need some with a different number of poles?

Well, actually you need a microphone and they have a microphone on them. But thanks!

This is irrelevant if e.g. Your headsets are three-pole but you need a four- or five-pole jack.

OK thanks!
