Hearing protection plugs are often used in dirty work environments. As a result, particles can easily settle on the surface of the material and cause minor injuries to the wearer's ear. The smooth and dirt-repellent surface of the uvex whisper, whisper+, and whisper supreme plugs can be easily cleaned with water and soap. This enhances both comfort and safety for the user. In the detec variant, the uvex whisper+ is easily detectable both visually and mechanically due to its striking blue color and a metal ball.
