As someone who love music I really like this idea! I tend to have music going where ever I am. A lot of people find it distracting but I’ve always found it relaxing and helps me focus. Not to mention it usually puts me in a very good mood, even if I’m ready to punch a wall. I would have to wonder about the price of these though. I bet their more than one pretty penny’s worth. Then you would have to think of the weather. If you’re out in the rain are they water proof? What if you step in a puddle? It’d be a shame to ruin these because of a careless step on the sidewalk. I’ve never spent more the $40 on a pair of shoes, so if I did buy these I would not want to have to buy them again. I wonder if they come with a remote? That would be cool, convenient, and smart for the sellers.
