The 3M E-A-R Classic Uncorded Earplugs, part number MMM 3101103, are designed for noise reduction in environments requiring hearing protection. These uncorded earplugs are constructed from polyvinyl chloride (PVC) foam, which is non-flammable and dermatologically safe. They are specifically sized for smaller ear canals, being 7% smaller than the standard 3M Classic earplug while maintaining the same length. The slow-recovery, low-pressure foam is engineered to conform to the ear canal's shape, aiming for enhanced comfort during extended wear. A key feature is their moisture resistance, which helps ensure consistent expansion time even in humid conditions. They are reusable and tested to ANSI S3.19-1974 standards, providing a practical solution for personal hearing protection.

Uncorded earplugs for smaller ears are made of nonflammable, dermatologically safe foam. PVC foam is nonirritating. Slow-recovery, low-pressure foam conforms to the shape of the ear canal for enhanced comfort and wearability. Moisture-resistance helps maintain a consistent expansion time, even in humid environments. NRR 29-decibel earplugs are 7 percent smaller than the 3M Classic earplug (and the same length) to fit comfortably in smaller ears. They are also tested to ANSI S3.19-1974.
