Engineered for reliable, everyday hearing protection, the 3M™ E-A-R™ Classic Earplugs are a trusted choice in noisy industrial environments. Designed with a slow-recovery cylindrical foam, these disposable earplugs conform gently to the unique shape of the ear canal, delivering consistent attenuation and all-day comfort. Suitable for a wide range of industries including manufacturing, metal fabrication, construction, and MRO applications, this model offers dependable protection for users exposed to hazardous noise levels.

Whether used on assembly lines or during tasks such as sanding, welding, or paint preparation, the E-A-R™ Classic model offers a snug, secure seal that helps reduce noise-related risks and fatigue in the workplace. A moisture-resistant barrier enhances durability and effectiveness—even in warm or humid conditions.

Key Features

Consistent Noise Reduction: Slow-recovery foam expands gradually to fit the ear canal securely, helping to maintain a reliable acoustic seal.
Moisture-Resistant Foam: Helps maintain effectiveness in humid or high-temperature environments, making it ideal for industrial applications.
Universal Fit: The cylindrical shape accommodates most ear canals and offers deeper insertion for effective attenuation.
Comfortable for Extended Wear: Soft, non-irritating foam enables use over long shifts without discomfort or pressure.
Economical & Disposable: Offers cost-effective hearing protection without compromising safety or performance.
Test-Ready: Compatible with the 3M™ E-A-Rfit™ Validation System for on-site fit verification.

Intended Use

Ideal for high-noise environments where disposable hearing protection is preferred or mandated. This model performs well across a variety of industries, including:

Automotive and metal fabrication
Construction and general manufacturing
Maintenance, repair, and operations (MRO)
Mining, marine, and oil & gas sectors
Military, pharmaceutical, and transportation applications

The uncorded version is particularly useful for single-use scenarios, minimizing the risk of contamination in clean areas or when easy disposal is required. Meets the needs of professionals exposed to intermittent or continuous noise, including welders, machine operators, and facility maintenance crews.
