There are very few things I like about these earbuds. I have tried several sports buds and other bluetooth earbuds. I would not use these for phone calls because you feel like you are in an echo chamber. It is distracting. I have actually never had a bluetooth set that quite acts like these when it comes to echoing. It makes talking on the phone uncomfortable.

Music sounds great on these and the earbuds come in different sizes so they fit well and do not fall out. The controls are difficult to manage as they are small and narrow. If you put the strap in back as most athletes do, you cannot access the controls at all as they are on the strap.
