these light weight comfortable headphone really do sound great . . I would know because I be use they right now !! after switch from my 40 dollar koss one I can immediately tell the difference . when use the hd 477 's you will hear new sound in every song you listen to that you old older headphone could not bring out . every sound be clear and that bass be better than expect in my opinion . the only little problem I have with these headphone be that if you leave they on too long they can tend to bother you ear a bit , but maybe that just I . for a affordable price the hd 477 's be most deff worth it !!
