if you be a fan of heavy bass , and a sound that blow you away , these be not the headphone for you . however , the sound be crisp and clear and mellow . you can hear part of song that you have never hear before . that say , the crispness be only too clear to listen to mp3 and other low-quality music source . the headphone bring out they imperfection , as lower quality headohone would disguise they in the mush of they sound . these headphone be great deal at 20 buck for those who do not want to be blow away by a wall of sound and rather appreciate the finer element of any genre of music .
