Moldex Cordless Earplugs

56 Uncorded Moldex Plugs · NRR 20–33 · Foam & Reusable · Wall Dispensers, Refills & Plain Packs

Which Moldex cordless earplugs should you choose?

Short answer: for maximum attenuation in plain packs, Pura-Fit 6800 at NRR 33. Where a dropped plug must be recoverable, SparkPlugs 6604 at the same rating. For smaller canals, Meteors 6870; for easier insertion, the twist-in Glide 6940. If you are stocking a wall station rather than a shelf, jump to the dispenser section below first.

Editor's pick: Pura-Fit 6800 — NRR 33 in a 200-pair box, no cord to snag, and a tapered foam that suits the widest range of ear canals. Fit does more for real attenuation than the last decibel of rating.

Our methodology: how this collection was curated

We record each family's NRR exactly as Moldex states it and never average across families. Because most items here are dispensers or refills rather than plain packs, we identify which is which — a distinction the product names do not currently make reliably, and one that decides whether what arrives is usable on its own. We list only genuinely uncorded products on this page; corded versions of the same families have their own collection, and we do not blur the two to pad a listing.

Moldex Cordless Earplugs (2026)

Cordless — Moldex labels them uncorded — means two separate plugs with no connecting cord. The trade is straightforward: nothing dangles to catch on rotating machinery or hook a hard hat, but a plug removed mid-shift goes in a pocket rather than hanging on the chest, so it is easier to lose and easier to contaminate. That makes cordless the right default where plugs go in once and stay in, and corded the better choice where people move in and out of noise. Under OSHA 29 CFR 1910.95, protection is required above an 85 dBA eight-hour average and employers must offer a choice. The NRR is an EPA laboratory figure, and NIOSH notes field attenuation is typically lower — fit matters more than the printed number.

What this collection covers

Fifty-six Moldex uncorded earplugs, spanning NRR 20 to 33:

• Plain packs, NRR 33 — Pura-Fit 6800, Meteors 6870, Softies 6600, Zebras 6920, and the moisturizing Soothers 6680.
• Metal-detectable — SparkPlugs 6604 at NRR 33, for lines with inline detection. See metal detectable ear plugs.
• NRR 30 — twist-in Glide 6940 and Mellows 6820, for anyone who finds rolling foam awkward.
• Wall dispensers and their refills — 33 of the 56. The Moldex plug station lines — PlugStation, EcoStation and TouchFree — run from 150 to 750 pairs, each with a matching refill: SparkPlugs PlugStation 6644, and the Meteors EcoStation 6707 with its 6708 refill.

Family and format comparison

How to buy uncorded ear plugs without ordering the wrong thing

Is this a dispenser, a refill, or a plain pack?

Check before anything else, because 33 of the 56 products here are stations or refills and the names do not separate them cleanly. The clearest example on this page: the Meteors EcoStation dispenser is 6707 and its own refill is 6708 — a wall unit and a bag of plugs with nothing to mount them in, one digit apart. The reliable place to read this is the product handle in your address bar, which spells out dispenser or refill, the station family, and the pack count. Order a refill without owning the station and you have loose plugs; order a second station and you have paid for hardware twice.

Cordless or corded?

Cordless suits continuous noise where plugs go in at the start of a shift — nothing hangs down to catch on machinery, and there is no cord to fray. Corded suits intermittent noise, because the plugs stay with the wearer between uses and are much easier to find when dropped. Cordless plugs that come out mid-shift tend to end up in a pocket, which is how grit gets into an ear canal. Moldex offers most families both ways; our corded vs cordless guide works through the choice, and the Moldex corded collection holds the alternatives.

Which station size do you need?

Capacities here run from 150 to 750 pairs. Size to consumption rather than to the wall: a station that runs dry is worse than a smaller one refilled on a schedule, because an empty dispenser trains people to walk past it. Wall-mounted PlugStation and EcoStation units suit fixed entry points; the TouchFree variants dispense without hand contact, which matters on food lines and anywhere hand hygiene is controlled. Best earplug dispensers compares the formats across brands.

Does NRR 33 mean 33 dB of real protection?

No. The NRR is a laboratory figure derived under ideal fitting conditions, and NIOSH is explicit that workplace attenuation is typically well below it. That is why a correctly inserted NRR 30 beats a badly inserted NRR 33, and why over-protection is a genuine problem — cut too much and speech and alarms disappear, so people take a plug out entirely. Match the rating to your measured exposure using the NRR calculation, and see what NRR actually means.

Why choose metal-detectable plugs?

Because on a food, beverage or pharmaceutical line a lost plug entering the product is the hazard, and an inline detector will only catch a plug built to be caught. SparkPlugs carry an embedded metal element at the same NRR 33 as the standard foam, so there is no protection penalty for the extra safeguard.

Insertion, hygiene and replacement

Foam plugs only deliver their rating if they are rolled to a thin crease-free cylinder, inserted while pulling the ear up and back, and held until they expand. A plug perched in the outer ear gives a fraction of its number. Twist-in designs such as Glide skip the rolling step, which is worth considering for crews who fit plugs with gloved or dirty hands.

Replace foam when it is soiled or stops expanding crisply — daily for most users. Never share plugs, and do not carry loose foam in a pocket, because grit picked up there goes straight into the ear canal on the next insertion. That last point argues for a dispenser at the entry point rather than a box on a shelf: plugs taken fresh at the door stay clean. Further reading: best foam ear plugs.

Moldex cordless earplugs FAQ

What does cordless mean on a Moldex earplug?

Two separate plugs with no connecting cord — Moldex labels these uncorded. Nothing dangles to catch on machinery, but a removed plug is easier to lose than one on a cord.

How do I tell a dispenser from a refill?

Read the product handle in the address bar: it states dispenser or refill, the station family, and the pack count. The Meteors EcoStation dispenser is 6707 and its own refill is 6708 — one digit apart.

Which Moldex cordless plug has the highest NRR?

NRR 33, reached by Pura-Fit, SparkPlugs, Meteors, Softies, Zebras and Soothers among the uncorded range. That is the top of the NRR scale for earplugs.

What is moldex 6644?

The SparkPlugs PlugStation dispenser holding 250 pairs of metal-detectable NRR 33 plugs — a wall station rather than a plain pack.

Should I choose cordless or corded?

Cordless for continuous noise where plugs stay in; corded for intermittent noise, because the plugs stay with the wearer between uses and are easier to find when dropped.

What station capacities are available?

From 150 to 750 pairs across the PlugStation, EcoStation and TouchFree lines. Size to actual consumption — an empty dispenser trains people to walk past it.

What is a TouchFree station?

A dispenser that releases plugs without hand contact with the remaining stock, which matters on food lines and wherever hand hygiene is controlled.

Does NRR 33 mean 33 dB of protection in practice?

No. The NRR is a laboratory figure and real-world attenuation is typically lower. A well-fitted NRR 30 outperforms a poorly fitted NRR 33.

Why are some plugs metal-detectable?

So an inline detector catches a plug that falls into the product stream, which is a requirement on many food, beverage and pharmaceutical lines. SparkPlugs do this at NRR 33.

How do I insert foam earplugs properly?

Roll to a thin crease-free cylinder, pull the ear up and back, insert, and hold until the foam expands. Twist-in plugs like Glide skip the rolling step.

Can cordless earplugs be reused?

Foam plugs are single-use in practice — replace when soiled or when they stop expanding crisply. Never share plugs between people.

Are Moldex twist-in plugs easier to fit?

Many people find so, since there is no rolling step. That helps most where hands are gloved or dirty, which is exactly when rolling foam goes wrong.

Why trust WC Safety on hearing protection?

WC Safety reviews workplace PPE full-time as an independent affiliate site — we do not sell products, hold no inventory, and accept no paid placements. On this page that means two specific things. We say plainly that a laboratory NRR overstates real-world attenuation, rather than presenting 33 as a promise. And we flag the packaging problem in this range instead of glossing it: most items here are stations or refills, several share near-identical names one digit apart, and we would rather tell you where to check than let you order a refill for a station you do not own. Standards referenced are OSHA 29 CFR 1910.95 and NIOSH hearing-loss prevention guidance. Reviewed by Steven Eaton, WC Safety editor. Last reviewed: July 2026.
