The 3M E-A-R Classic Foam Earplugs are the world's first foam earplugs and the recognized industry standard for disposable hearing protection. Each pair is made from a proprietary soft, slow-recovery PVC foam that compresses easily for roll-down insertion and then gently expands to conform to the unique contours of the ear canal, delivering a Noise Reduction Rating (NRR) of 29 dB. The signature yellow cylindrical design is instantly recognizable on job sites across virtually every industry, including manufacturing, construction, welding, grinding, sanding, machining, food processing, and facility maintenance.

Each pair comes individually wrapped in a convenient pillow pack — a small, reusable pouch made from pulpable, recyclable, and biodegradable material — making it easy to keep a pair in a pocket, toolbox, or vehicle glove box while maintaining cleanliness until use. The moisture-resistant foam retains its performance characteristics throughout a full workday. These earplugs are compatible with the 3M E-A-Rfit Dual-Ear Validation System, enabling employers to objectively verify the level of protection individual workers achieve with proper fit. Certified to CSA Class AL standards and made in the USA. This Costco package contains 200 individually packaged pairs per box.
