I was impressed that they stayed in my ears! The only time Ive had it die before I got home I was gone over 13 hours using it near constantly. Second I had to make sure that my phone clears the handlebar when it is turned to release. He is comfortable with them. The sound was way better than I expected, good range with the base coming through nicely. I was once a loyal Crocs supporter but now will have to look else where for my shoes. There was some extra material on the top of the shoe but you can only tell if you are looking closely. They buds to have to go in a certain way to charge so you have to pay attention to that. This is a very small, very light canopy drape. I was packing it up and made one more effort plugging it in to my phone jack.
