Speak with Fortnite headphones?

How does this "Team Speak" or no idea what that means (I'm not familiar with xD) at Forrnite. I already know how to turn it on but I do not have a headset or anything. Is that possible with headphones? If so, where do I have to speak then haha?

If you want to talk to other Kiddis you need a microphone. Or you stream live pantomime with a camera. I would watch…

If you want to play this on the Nintendo Switch then you would not be able to use a headset because the console does not support it.

For Team Speak you would have to have the extra Nintendo app on your phone, otherwise it will not work.
