3M E-A-R Classic Soft Earplugs are made of soft foam, as the foam warms to the body temperature, it becomes softer and shapes to the individual's ear canal. This 'shaping' allows the earplugs to form an excellent seal against noise, and as time goes on, the foam continues to soften for added comfort.
- Cylindrical shape that fits most ear canals and provides a reliable seal
- Textured surface helps keep earplugs in place
- Helps reduce moisture and sweat build-up thus improving comfort
