🔇 3M E-A-R Classic Ear Plugs – Foam Hearing Protection
🔇 World-Class Hearing Protection
More than 40 years ago this simple hearing protector, the world's first foam ear plug, revolutionized hearing protection in the workplace and has remained to this day one of the most widely used earplugs in the world.
The 3M E-A-R Classic Ear Plugs OCS1137 are constructed from slow-recovery, low-pressure foam. They fit snugly to create a noise barrier that helps protect hearing from loud sounds. These ear plugs are stiff enough when compressed to make fitting easy, yet soft enough to be comfortable in the ear for extended wear.
Bright yellow color allows supervisors to conduct quick visual hearing protection compliance checks. Moisture resistance helps maintain a consistent fit, even when humidity is present.
