There is a built-in mic
You can use a BT headset
You can also use a wired headset ( may require slight modification to work right )
You can use regular headphones and the built-in mic ( works quite well that way unless you are trying to be quiet ).

Most of what you will need to get going can be download from "Extras" which takes 30 seconds to enable. I'm sure people will happily suggest what apps you need. When you are home, if you are from the capital district area and really need help, drop me a pm.
