Moldex Spark Plugs offer the highest independently tested NRR 33, which makes them a good fit for most loud environments.

Foam Moldex ear plugs are made with extra-soft low-pressure foam and offer a non-irritating smooth feel for comfort and fit. Even the smallest ear canals will benefit from the tapered shape that increases the seal and comfort over long-term wear.

6604 Moldex spark plugs are 100% PVC-FREE, and are also available in a magnetic EcoStation Ear plug Dispenser that can be easily refilled to decrease waste and save you money.

Need A Metal Detectable Version? You can also get your Moldex Spark Plugs with a metal detectable cord. Bright blue in color, and perfect for food processing environments, the enclosed metal ball bearing and cord are in separate holes so that the earplugs remain detectable even if the cord is removed.
Using corded earplugs prevents earplug loss.
