How do I talk to other people from Fortnite with Headset?

It is completely boring if you do not hear anyone talking, how can I stop it? Or is this not possible at all? (no matter which mode)

With people from Fortnite "sry

Well it depends on whether your team members have a headset or micro. Then you can hear them talking. But many prefer to remain anonymous and mute the microphone, then you will not hear them.

It's best to talk to them in the lobby or when jumping from the bus, and then someone answers back.
