Reduced pressure.

According to users and safety directors, pressure in the ear canal leads to uncomfortable wearing experience. The Classic earplug has a lower equilibrium pressure than many other competitive earplugs.*

*Lab results for medium and smaller ear canals, (Aearo Technologies R&D Labs, February 2008).

Sweat & humidity absorption resistant.

When some other earplugs absorb sweat or humidity, users report they can get slippery and can back out of ear canals. Classic earplugs are absorption-resistant, reducing moving and shifting problems when using in moist conditions.

Resists flammability.

Arc flash exposure? Explosion potential or other flammability concerns with wearing or storage? Classics have been tested and proven to be flame retardant. *
Classic also exceeds US Military specification Mil-P-37407B test requirements for an earplug to resist combustion, and has been successfully tested for ARC exposures of Category 2 and higher, ASTM F1959-2005 modified.

Stays in place with textured surface.

Classic's exposed cell surface texture resists shifting, and that helps maintain an effective seal.

Outperforms tapered.

According to a British Steel technical study, cylindrical plugs outperformed tapered plugs for actual in-use protection levels. (Scott, R.F. (1995), "Study of Factors Affecting At-Work Protection Afforded by Hearing Protection Devices in Steelworks," British Steel plc, Doc. FR s373-5 942, London, UK. (/2111/).

Fits the most ear canals.

All ear canals are unique. When compared to other foam earplugs, the universal-sized Classic has proven to fit the widest range of ear canals and meets the product dimensions of Mil-P-37407, the specification defining U.S. Military requirements for foam earplugs.

Protects without irritation.

The Classic earplug's length, width and flat tip are designed to fit and protect without irritation. Materials are continually tested for dermal irritation.

Military tested and approved.

E-A-R Classic meets the rigorous demands of every branch of the military for both training and combat. In fact, the Air Force conducted protection level studies and found that the Classic delivered the highest protection level of any single hearing protector tested.

Prove it with the E-A-Rfit™ validation system.

Fit, unique ear canal shapes and other factors can affect an earplug's performance. No need to guess with the Classic. In just 8 seconds, EARfit produces data at seven standard frequencies, giving each individual a Personal Attenuation Rating (PAR) under the test conditions.

*Research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in earplug fit and wearing time. It is recommended that the NRR be reduced by 50% for estimating the average amount of noise reduction provided.
