like many , I like to listen to music while I run . well , it be a little difficult with these . they do not stay in my ear , they be painful when I try to position they correctly -lrb- and I be constantly reposition they as I run -rrb- and the over ear plastic section be uncomfortable as well . I be think about go back to my  Nike HJ030 Vapor Sport Bud headphone  -lrb- although the plastic break after a year on the Nike 's , they be actually comfortable and stay put ! I 'll invest the money and actually send in the warranty this time ! -rrb-
