I have used Ultimate Ears super fi. 4vi for iphone. unfortunately the feature (pause music, go to next song) didn't work with first gen. touch. now, new one has built-in speaker, volume control. headphone recognizes new touch as iphone. so you can pause, replay, go to next song by pressing button. it's actually very convenient. now, I don't have to put it out for changing song during shuffle mode. if you have one, try this.
