I can not say enough bad thing about these if you be go to use they for run . they be make to go on you arm , so one cord be longer than the other . they have a connector half way down that come with a extender enable they to be longer and attach to to you waist , but this make the cord heavy thus pull they out of you ear . because the cord be rubber they also bounce a lot when run . I give they two star since they do come with multiple size piece that fit nicely into you ear . if you be go to sit still when use they they be great . if you be plan on use they actively keep look .
