I bought the klipsch s4i along with the iPhone4 on iPhone4's launching day cause I thought my new phone deserves a good earbuds.  Boy was I wrong. klipsch s4i is nothing more than a piece of crap! Please excuse my language or if I offended any klipsch fans, but im just trying to speak of my mind. The sound will break when the note is too high and there is absolutely no bass. I really thought the old model earbuds made by Apple that came with the iPhone4 is better than the klipsch s4i.
