Water in Ears

Those ear bands are made of a neoprene material, There used mostly with children to hold earplus in. They wrap around the head and have a velcro closure. Since they can not be placed tightly around the head/ears I dont see how thay can hold the earplugs in. Just to keep them from falling all the way out. Much better is a home made swim band made from a silicon cap or a complete silicon cap with a bubble strap cap over in a snug head size. That and some good ear plugs, Macks, or custom molded. go over any tips with your Doctor .
