For Sound: I had read reviews in which has been complaining about the weak bass. The I share absolutely not. In my iphone 3gs (where, incidentally, all controls work wonderfully and without delay) I even have the equalizer taken out because I was even too much bass. With the factory settings, I'm on a very balanced sound with lush bass, clear mids and highs. Of course, one must note that the ear pieces sit properly. Otherwise, the sound is naturally not play correctly. But that is no problem with the five included essays that comfortable (but not too tight) fit your ears.
Others: As mentioned earlier is not a case but just a cheap cloth bag included. Therefore, and due to the slightly looser fit there a star deduction.
4/5 stars, performance / price is great!
