Where do I find a mic port for my Xbox 360 controller
Where you plug in your mic is the the port at the bottom of the controller right in the middle. I'm not quite sure if that's what your asking for.
I'm not sure... but I'd search on the internet. I don't know if it's built-in or if it's able to buy... you didn't ask very specifically.. but if it's buyable, look on Amazon, if it's built-in, then ask the internet. Hope this helps!
