I have this type of head phone and use it for a number of year till recently it blow out . . I look everywhere in the past 3 month to replace these . I jog 3 to 5 mile a day and sweat profusely . . ear bud would not stay in due to sweat . . my ear be small so try at least 5 different style and nothing work . . these be great because the tension make sure they stay in . they might not be as cool but as far as function a + + + . .
