3M Officially Licensed Edmonton Oilers 3M Hi-Fidelity Earplugs with Aluminum Laser-Engraved Key Chain Container

The 3M™ E-A-R™ Hi-Fidelity Earplugs, Hearing Conservation, have an acoustical design that reduces noise levels across all frequencies without distorting or muffling the sound. These earplugs provide lower attenuation than standard pre-molded earplugs, allowing the wearer to hear conversation and sounds more easily. Recommended for TWA noise exposures below 90 dBA. The pre molded, triple-flange design makes the earplugs easy to comfortably insert. The earplugs are reusable, which reduces the long term cost of buying replacement disposables.
