these be the best sport earbud on the market . they be light and with the wrap around on the ear stay in place . no ear bud be perfect , but these be inexpensive enough that they can be replace without too much out of pocket cost . Let 's face it . cheap or expensive nothing can last year and year when sweat be part of the natural routine of a ear bud . I have have expensive one and these be just as good . they get a 5 star mark for they practicability and cost .
