Replying to Skull Candy Question

So i have the Giro 9 with tune ups. I have the cord for the whole connection to my ipod but either im stupid or my cord has no mute button. My homie has a cord that has a mute button that he just has to hit when someone is talking to him. Right now i have to like dig into my jacket and turn it down. I need the cord with the mute button. Is there a certain cord i need to buy or have i just not figured out how it works and if that is so please enlighten me.

thanks
