With light weight training sessions and everyday usage their great. Comfortable, good sound quality, battery's good. Any kind of moderate moving like running and jump rope these are falling out. Sweaty people stay away as well, because when these puppies get wet it's a slipping slide Everytime you put these in your ear. When I tried to return them customer service was not helpful. Also sometimes when you turn them on the left earbud will not connect and it's the most frustrating thing ever.
Great for simple usage, moderate to intense athlete stay away
