The ER 20 S is a hearing protector that protects your ears from excessive noise and yet hardly influences the sound perceived from speech and from the environment. This is ensured by a filter that isolates nearly linearly across the frequency spectrum. This way the sound of the environment and speech is maintained, compared to isolation without filters.
