I have tried a lot of ear buds. I use mine constantly for work, driving, and just walking around. There has only been a couple of times where I have had to reposition it. Unlike the over the ear style, with more use it doesn't loose it's shape and continue to fall off your ear. The best part of this ear bud is it doesn't pick up wind and has excellent sound. I have had mine for over a year and haven't needed to use the spare mic that comes with it.
