This headphone is beautiful, light and transparent. I wore them for about a week or so but my husband had them for a while longer. I bought a pair at his suggestion. According to him, they are ideal for training (higher intensity workouts like fast running). They don't move much (I shook my head to check). One issue I had is that the ear hooks are so flexible that it doesn't feel like they will stay put, but they will. It's just a different feel because the silicone is a lot lighter than other headphones I've had. The case also seems solid, it seems to survive an accidental drop or two, stays shut (magnetized, there's no clasp to accidentally break with repeated opening/closing). I don't feel like it accidentally opens up in my purse. The earbuds sit deep in the case so they cannot fall out. One thing I'd like to see is a case that shows the percentage of battery left, but they last a long time so I haven't had to charge mine yet (it's been a week and I've been using them for an hour or so daily) . The headphones come with an extra set of ear hooks and two sets of the in-ear piece. I have a white pair and my husband has a black pair.
