I have read all kind of review of this one on amazon before I place the order . after I get the product , I be so pleased that it depress most of the ambient noise . I be so happy that I do not even hear the buzz make by my desktop computer fan . it be just great for such price . and the sound be just ok for I -- I be not a audiophile , I just use it to listen to mp3 . the only reason I do not give it a full score be it be not so comfortable to wear it for a long time .
