these headphone have a excellent sound quality for the price . it have a deep bass that , in my opinion , be well balance with the high and low . I play bass guitar , so I tent to enjoy a bass that be a little more pronounced rather then be subdue . the headphone themselves , while large in size , be comfortable and durable . my wife stretch they to they limit to place this on she belly so we soon-to-be-born son can listen , and there be no damage or stretch on the part of the headphone . after have use earbud for so long , I be amaze at the nuance in my music and movie that I can hear with these headphone . great job Sony !
