Pretty good waterproof headphones for the money. I use them riding a PWC at speeds up to 80 mph and they sound good at all speeds. My only complaint is they don't stay in your ear as well as others. I blame the angle of the stem (or the stem being there period) which seems to help keep them from being seated snugly in your ear. I would NOT recommend these for swimmers....only those above water who need the waterproof protection.
