Earplug hearing protectors effectively shield against high noise levels, both in leisure activities and especially in industry, such as automotive, chemical and pharmaceutical, construction, etc. They also reliably protect against unpleasant wind and help you calm down before sleep. The soft foam easily fits into the ear when held in place for half a minute to a minute. They are based on soft, noise-absorbing polymer foam. The ergonomic shape and low equilibrium pressure increase wearing comfort.
