Moldex Cordless Earplugs

Uncorded disposable earplugs remain the most widely used hearing protection format in American workplaces — quick to reach for, easy to carry, and available in every NRR rating from 28 to 33 dB. Moldex uncorded earplugs are manufactured in the USA, free of PVC and harmful plasticizers, and engineered across multiple foam formulations to deliver all-day comfort and reliable noise attenuation in manufacturing, construction, machining, woodworking, and any environment where noise exposure exceeds safe limits.

SparkPlugs® 6604 is the flagship of the Moldex uncorded lineup — and one of the most recognizable disposable earplugs in the industry. Its tapered, brightly colored foam stem inserts without rolling, making proper use intuitive even for first-time wearers. SparkPlugs® achieve NRR 33 dB, the highest noise reduction rating available for disposable earplugs, and are available in bulk poly bags, boxes, and PlugStation® 6645 bulk dispensers (500 pairs) for high-volume PPE stations. The dispenser format promotes sanitary, one-at-a-time dispensing, reduces waste, and simplifies restocking.

Pura-Fit® 6800 uncorded earplugs feature a contoured, skin-smooth foam that expands gently and gradually after insertion for a seal that feels snug without pressure. With NRR 33 dB protection and a design that accommodates a wide range of ear canal sizes, Pura-Fit® is frequently selected for all-day production line use where comfort over extended shifts is a priority. The PlugStation® 6844 and 6845 dispenser packs make bulk distribution easy.

The Glide® uncorded series (6940 and 6941) introduces a patented polymer foam that requires no rolling or compression prior to insertion — workers simply twist and push. This no-touch approach is ideal for environments where hand cleanliness is critical: food processing, pharmaceutical manufacturing, clean rooms, and any application where gloved workers need to insert earplugs without removing gloves. Glide® provides NRR 30 dB, and the Glide® Soother (6980) adds a moisturizing surface treatment for workers prone to dry ear canal skin, achieving NRR 31 dB.

Meteors® 6870 brings a distinctive tapered bell shape that provides excellent canal conformance at NRR 33 dB, while Meteors® Small 6630 is specifically designed for workers with smaller ear canals who find standard-sized earplugs uncomfortable or difficult to achieve a proper seal with — it offers NRR 28 dB in a reduced-dimension foam body. Softies® 6600 uncorded earplugs use an ultra-soft, non-irritating foam that remains one of the gentlest options in the Moldex lineup, achieving NRR 33 dB for workers who experience irritation from firmer foams.

Additional uncorded options include Mellows® (NRR 30 dB), Camo Plugs® (NRR 30 dB), Goin' Green® eco-friendly earplugs made with bio-based materials (NRR 33 dB), and Zebras® (NRR 30 dB) — expanding the lineup with high-visibility colors and specialty materials for facilities with specific earplug accountability or sustainability program needs.

OSHA's hearing conservation standard (29 CFR 1910.95) requires employers to provide hearing protection when noise exposure exceeds 85 dBA as an 8-hour time-weighted average. At 90 dBA or above, protection is mandatory. Moldex uncorded earplugs at NRR 33 dB provide theoretical noise reduction of up to 16.5 dB using the NIOSH recommended method, making them appropriate for most industrial applications.

WC Safety carries the complete Moldex uncorded earplug lineup in single-pair poly bags, bulk boxes, and PlugStation® dispenser configurations. Shop by model, NRR rating, or foam type to find the right fit for your workers and your facility's hearing conservation program requirements.

Frequently Asked Questions

Which Moldex cordless earplugs have the highest NRR?

The NRR 33 group is the highest here: Softies EcoStation (6531, 6532), SparkPlugs (6533, 6534, metal-detectable), Pura-Fit (6535, 6536), and Meteors EcoStation (6537). The Rockets, Alphas, and Jetz reusable plugs are NRR 27, and the BattlePlugs Extra (6496) is NRR 20. Subtract 7 per OSHA to estimate field performance.

What is an EcoStation cordless plug and where is it useful?

EcoStation models such as the Softies 6531/6532 and Meteors 6537 are dispenser-fed cordless foam plugs that supply single pairs at point of use. They suit high-traffic plants where workers grab fresh plugs each shift, supporting hygiene and consistent availability. At NRR 33 they offer top-tier lab attenuation for sustained high-noise areas.

Why pick cordless Moldex plugs over the corded versions?

Cordless plugs remove any dangling cord, which matters around rotating machinery and conveyors where a cord could snag. They suit continuous all-shift wear with infrequent removal. Corded versions are better when you remove plugs often and want them tethered at the collar; both lines share comparable NRR for the same foam body.

Are the foam Pura-Fit and SparkPlugs reusable or disposable?

Pura-Fit (6535, 6536), SparkPlugs (6533, 6534), and EcoStation foam plugs are single-use disposables; foam absorbs moisture and wax that degrade the seal, so replace each shift or when soiled. The Rockets, Alphas, and Jetz here use a washable flanged body intended for cleaned reuse until the flanges wear or stiffen.

Why are SparkPlugs 6533 and 6534 marked metal-detectable?

SparkPlugs are made detectable so a dropped plug can be located by metal-detection equipment, supporting foreign-object-prevention programs in food and pharmaceutical processing. They deliver NRR 33 while adding that traceability. If your facility runs detector-based contamination controls, choose detectable plugs over standard foam to stay compliant with your HACCP-style procedures.
