yeah I know you were serious. i just thought your reaction was funny XD
i'm not sure how it would work. it depends on how the headset interfaces with the iphone/computer. is it USB? if not chances are you can only make it work as either a mic or speaker depending on what jack you plug it into. if your mac has a built in mic thats a perfectly viable option too, and probably more likely to work than the headset. if its a macbook i imagine it has a camera and mic already.
i wonder what your roomate will think about you singing to your computer XD
thanks for joining the project btw, i like your enthusiasm
