I find these headphone quite comfortable , even after a few hour of use . I be surprised to see many review say that they be extremely uncomfortable . sure they be not the most comfortable headphone I have worn , but they be pretty good . pro : dazzling detail . exhilarating `` surround '' experience . in-your-face presence ... like be in the front seat at a concert . and good balance : it be exciting to hear the crisp treble , warm mid , and full-but-unexaggerated bass - all at once . con : the treble can sound a bit harsh at time , depend on the recording , especially for classical music . I just turn down the treble a bit for those recording , and the result be easier on my ear . they do not block out external noise at all , and other in the room will easily hear you music as they ` leak ' sound . but I have read that ` open ' headphone like these have potentially better sound quality than isolate one .
