The ER-20 is a hearing protector designed to lower the volume of sounds without distortion. The result is a feeling of turning down the volume. ER-20 is the ear plug for those who need to communicate in a noisy work environment (e.g. teachers, airport crew or factory workers) or during leisure time (e.g. musicians, motor sport spectators or being in noisy bars and clubs).
ER-20 offers good sound quality and high comfort thanks to its smart design. The stem, with its unique acoustic resistor, combined with the end cap, contributes to a well tuned acoustic circuit. The result is an average attenuation of 20dB over all frequencies. The ear tip, which fits almost all sizes, is made of soft silicone to guarantee high comfort.
