I remember vividly wearing my first pair of hearing aids on a bike ride. If I could have found the ice cream truck I would have killed the driver. He must have been on a parallel block but it went on for blocks up a hill. That aside, I decided that sweat would also kill them and there was too much ambient noise.
My latest pair (Costco but not branded) have a rechargeable battery making them less hassle since there's no tiny battery to deal with. But I still don't wear them - as noted, too much wind noise and still all the other ambient noises.
