FWIW, When I bought my iPhone, I looked at the earphones that they had in the apple store. They had an interesting (but very expensive) set that simply blocked waaaay too much outside noise. I got the vmoda vibe duo because a) I could still hear conversations around me through them, and b) it had the cleanest mic sound. I can talk into the mic going 30mph and the person on the call can hear me just fine! Uh oh, am I going to start a talking on the phone while biking backlash now?
