Moldex 6880 SparkPlugs Corded Earplugs Overview

The Moldex 6880 SparkPlugs Corded Earplugs are corded single-use foam ear plugs from Moldex, rated NRR 33 dB. The permanent cord keeps the pair together so a plug isn’t lost, and lets you hang them around your neck between tasks. They are metal-detectable — a metal element lets food-line detectors catch a lost plug, so they suit food and pharma production. Start with our hearing-protection guide and what NRR means, then confirm the noise level you’re protecting against.

The Moldex 6880 SparkPlugs belong to the corded ear plugs range and the NRR 33 ear plugs group. They are single-use (replace when soiled or no longer springy); for the trade-offs see foam vs reusable ear plugs.

What NRR 33 dB Means

NRR is a laboratory rating; NIOSH suggests derating it for real-world use. Here is how NRR 33 dB lines up with common environments (always confirm with a noise survey):

Who Should Buy the Moldex 6880 SparkPlugs?

Buy them if you want single-use foam hearing protection with a retention cord at NRR 33 dB that's also detectable on food lines. Consider another plug if you need a different level or style: compare 6770 Flip-to-Listen, 6436 Alphas, 6435 Alphas. For the highest ratings see highest-NRR ear plugs.

Hearing protection only works when worn correctly for the full exposure. The NRR is a laboratory rating; real-world attenuation is typically lower, so OSHA and NIOSH recommend derating it when estimating protection. For very high noise — or whenever earplugs alone can’t bring exposure under about 85 dBA — wear them with earmuffs (dual protection). The Moldex 6880 SparkPlugs reduces noise; it does not eliminate it or protect against non-noise hazards.

Best Applications

Industrial & construction noise

Power tools, plants and construction work at sustained high noise suit a corded NRR 33 plug you won’t lose between tasks.

Food & pharma production

Detectable-loss control makes these a fit for food-safe production lines.

Moldex 6880 SparkPlugs Quick Answers

Does the cord lower protection?

No — the cord is for retention only; the seal sets the attenuation.

Are the Moldex 6880 SparkPlugs washable?

No — single-use foam; replace when soiled.

Plugs or muffs?

Both for the highest noise; see ear plugs vs ear muffs.

Moldex 6880 SparkPlugs Specifications

Fit & Sizing

The Moldex 6880 SparkPlugs are single-use foam corded ear plugs. To fit them, roll them down between your fingers, pull the ear up and back, and insert — they expand to seal the canal — the seal, not just the NRR number, is what protects your hearing. They are one size fits most and single-use (replace when soiled or no longer springy). Browse more options in foam ear plugs, the full corded ear plugs range, or all hearing protection. For detectable-loss control, see metal-detectable ear plugs.

Moldex 6880 SparkPlugs Frequently Asked Questions

What is the NRR of the Moldex 6880 SparkPlugs?

The Moldex 6880 SparkPlugs are rated NRR 33 dB (EPA-labeled per ANSI S3.19). Real-world protection is usually lower, so NIOSH recommends derating the NRR when estimating exposure.

Are the Moldex 6880 SparkPlugs corded?

Yes. The permanent cord links the pair so you don't lose a plug, and lets you wear them around your neck between tasks — the cord does not change the NRR.

Are the Moldex 6880 SparkPlugs reusable or single-use?

They are single-use (replace when soiled or no longer springy).

How do I insert the Moldex 6880 SparkPlugs?

To fit them, roll them down between your fingers, pull the ear up and back, and insert — they expand to seal the canal. A proper seal is what delivers the rated protection.

Can I wash the Moldex 6880 SparkPlugs?

They are single-use foam — replace rather than wash once soiled or no longer expanding.

Are the Moldex 6880 SparkPlugs metal-detectable?

Yes — an embedded metal element lets production-line detectors find a dropped plug, so they suit food and pharma lines.

What size are the Moldex 6880 SparkPlugs?

They are one size fits most.

What noise levels suit NRR 33?

NRR 33 dB suits common industrial noise once derated; for very high or impulse noise, add earmuffs for dual protection. See what NRR means.

Do corded ear plugs reduce the NRR vs uncorded?

No. The cord is only for retention; the plug body and seal determine attenuation.

Are the Moldex 6880 SparkPlugs NIOSH/EPA labeled?

Yes — NRR 33 dB is EPA-labeled under ANSI S3.19. WC Safety sells authentic Moldex hearing protection through legitimate channels.

Can I buy the Moldex 6880 SparkPlugs in bulk or by the case?

Yes. Use the Request a Quote option for case and dispenser pricing on volume orders.

Should I choose ear plugs or ear muffs?

Plugs suit tight spaces, heat and all-day wear; muffs are faster on/off. Many high-noise jobs use both — see ear plugs vs ear muffs.
