I am the user of this headset so I know better about it. It sound is good and also it cuts the voice from the surrounding. But its design is vary bad as it is a rectangular shaped headset which looks borring and lame. Although it has a good battery of 500mah which works non stop for 6 to 7hours. Its mic is not good as there is to much disturvance from the background you cannot talk with it, so it is not usefull for calling. And one more thing about this headphone is that one side of it is louder than the other side which I hate the most.
