We use the "doc's proplugs" for swimming with a cap over the top for added security as they fall out. We found these much gentler to insert as they are shaped to twist into the ear and have a Left and Right plug. There are different sizes but our ENT had some in his office and fitted a few sizes so he could tell us which were best. There is also a string joining the two plugs that goes behind the head so if one falls out, you don't lose it in the pool.
