Day in and day out hitting the open pavement can get a bit boring unless, you have some music to power you through. What bugs most of us when trying to run with music are the earphone/earbuds. They always fall out at the wrong time especially when you are in a groove. Yurbuds Ironman Inspire Pro claims it will never fall out and never hurt. It is a rather bold claim as no one ear is the same but it seems to work. They have a patented Ear-Lock technology that keeps these in on those intense workouts.
