The earplug hearing protector effectively protects against high noise levels both during leisure activities and especially in industry, for example in automotive, chemical and pharmaceutical, construction and similar sectors. It also reliably protects against unpleasant wind and when you need to calm down before sleep. The soft foam easily fits into the ear if held in place for half a minute to a minute. It is based on soft polymer foam that absorbs noise. The ergonomic shape and low equilibrium pressure increase wearing comfort.
