I do not recommend these earphones. I find them very uncomfortable to wear - the speakers dig into the ear because they are hard and chunky. The sound quality is also very poor - as well as poor bass, the speakers pop and crackle a lot. I have to use them at full volume, and even then they are too quiet. I think this is because the speakers don't fit well into the ear, so a lot of sound is wasted. There are better sports-style earphones available around this price.
