Customers occasionally send in reviews of the products they have purchased from PKSafety.com. We appreciate hearing how our products hold up in the field, and what are the favorites, especially in a product like ear plugs where there are so many choices. Jody in Los Angeles writes: "These ear plugs work really well and are my favorite for comfort. I've been a heavy equipment operator for over 33 years, I've tried them all. These are definitely my favorite. " When asked about the pros of the Moldex Pura-Fit, he cited the comfort and the dB rating. He's got a good ear for protection (probably thanks to keeping his ears safe all these years). In fact, the Pura-Fit 6800 Foam Earplugs have a noise reduction rating of NRR 33 - the highest independently tested rating on the market. Moldex makes the Pura-Fit 6800s specifically for hearing protection focused on occupational noise exposure prevention. Thanks for the review Jody.
