For those who are wondering, this is the Black beauty model with the braided cable and jack plug bent. The sound is beautiful to 30. The bass, treble, mids are very well rendered. For the geek there are mods to boost your headset as the "Kramer Mod" which involves drilling small holes in the cover that protects the driver to release more sound. I put foams by leatherette pads which has the effect of amplifying the low and ultra-low, to have the feeling of having baffles glued to ears. The helmet is light keeps well without being painful no risk of the way down during a workout. Given its high impedance you better have a pretty powerful player. Even high-volume headphones not sizzling. I board as MP3 player Sansa Clip Zip. So for under $ 100 you will have a portable audio system that will make green with envy iPod owners and Beats headset. Also has a lifetime warranty even if you hack!
