It's not surprising that custom molded ear plugs are highly effective at keeping sound and water away from your ears. Because they are fitted to your ear canals they are also more comfy than alternative varieties of ear plugs and are more likely to stay in.
ZenPlugs Molded Ear Plugs are unique in that they can be remolded as many times as you like. This is unlike silicon ear plugs which only give you one chance to get it right. Over the course of several years your ear canals may change shape. If you'd bought silicon molded ear plugs you'd have to throw them away and start again. With ZenPlugs you can just remould them and carry on using them; they last for years. You can get them from the Facebook Ear Plug Shop.
