Wrong settings on the headset?

I'm talking to a friend about TeamSpeak. We have the problem that he constantly hears his own voice and everything my laptop makes so loud, except for the game itself that we play. It's not that I don't have headphones inside, because I have. Does anyone know why that is?

Is the headset selected as the recording device?

Yes

What headset is it?
