this set of headphone be just outstanding , I have be involve with the audio world for 19 year include have work with pro audio and this be by far the best audio equipment purchase that I have make , these be the best bang for the buck ever . the phone sound very linear and clean from distortion , it be not the last word in resolution but it be still fairly accurate . even if it cost 4x more it would still be worth it imho . leo-300z
