Universal sized reusable earplugs provide superior noise reduction rating performance in any environment. Comfortable for extended constant wear, the protective gear has a very low impact on the ear canal. With the most advanced technology, choices feature ridged stems for better gripping or multi-flange designs with air pockets to personalize fit. Brightly coloured options expedite compliance checks and may offer disconnecting cord. Economic and reusable earplugs do not lose attenuation ability upon washing.
