Stream audio from Xbox to iPod/iPhone/iPad

Hi, I'm looking for a way to stream audio from my Xbox to an iOS device. For example, when watching a movie on my Xbox, I'd like to listen to it through my devices headphones. Same with games. I know I could buy a headset that would allow to me to do that directly with the Xbox, but I'd like to know whether its possible to do it with a device. I have smart glass, but I don't believe it does that. Suggestions?
