love these headphone . they last a very long time as compare with other headphone I have use . they be very comfortable and stay put even during very jarring activity such as run . they be also water\/sweat resistant . I have fry out many other headphone because of this and these be the only one that stay in my smallish ear without constant fiddling . Worth pay a little more for , but they be on the higher side for headphone . price have come down a bit due to a newer version out .
