speak without mic??

Hi all,i don't why i can do this but i can speak online with a friend without micro with the 360 slim.anyone know why?

Do you have a Kinect? It works as a microphone too.

no i don't have the kinect,when i talk i can ear me 3/4 second after...

lol it's okay i remember i was chatting msn video with a friend who have kinect and my voice is catched by his kinect

Haha nice, I'm sure I would've been hella confused too
