The TaoTronics SoundLiberty 79 are excellent headphones for sports. With their stability fins installed, they feel very stable and should stay in place even during more strenuous workouts. They have a long line-of-sight range, so you don't need to have your phone directly on you at all times, and they're rated IPX7 for water and sweat resistance, though we don't test for this. Unfortunately, with their stability fins on, it can be a bit finicky to charge them in their case, and you may think they're charging when they aren't.
