Ear plugs are part of personal protection equipment used for hearing safety. In order to shield the user’s ear from the impacts of loud noises, ear plugs are made to be inserted into the ear canal. They are not a replacement for protective equipment, but they work best when worn in hostile, noisy workplaces. They can also be used at home, such as as earplugs for sleeping. It is essential for both comfort and noise reduction effectiveness.

Canal caps have flexible ends that serve as caps to block the ear canals. Only the ear opening is sealed; they do not reach into the ear canal. As a result, they do not offer you as much security as earplugs or ear muffs.
