I hear mostly rock and pop music and use the Koss Porta Pro to an iPod Mini. This is the basis of the subsequent recession. He is rickety, looks fragile and not very nice. For that I can wear it for hours and the most important thing for me is sound, dynamics and transparency. In these disciplines the Koss beats anything in its price range. Neither provides a so crisp, deep bass without distortion and represents swings simultaneously to lofty heights. You will hear details (guitar plucking, claves, breaths of singers) that you did not hear before. This headset's just fun. Despite structural weaknesses are for me in a headset wearing comfort and sound the decisive criteria and therefore there are 5 star.
