Hearos Pearls Moldable Silicone Ear Plugs are a great solution for water protection, sleeping and noise protection up to 106 dB. Hearos Pearls are the first moldable silicone earplugs to come ready for use. No need to knead the plugs before insertion. Just remove them from the case and put them into your ears. Hearos Pearls are softer than ordinary silicone putty earplugs and they are tackier as well, so they seal the ear better, and require less pressure to get them properly seated.
