Elvex EP-412 Quattro Corded Earplugs Overview

The Elvex EP-412 Quattro Corded Earplugs are corded reusable flanged ear plugs from Elvex, rated NRR 27 dB. The permanent cord keeps the pair together so a plug isn’t lost, and lets you hang them around your neck between tasks. Start with our hearing-protection guide and what NRR means, then confirm the noise level you’re protecting against.

The Elvex EP-412 Quattro belong to the corded ear plugs range and the NRR 27 ear plugs group. They are reusable and washable across many shifts; for the trade-offs see foam vs reusable ear plugs.

What NRR 27 dB Means

NRR is a laboratory rating; NIOSH suggests derating it for real-world use. Here is how NRR 27 dB lines up with common environments (always confirm with a noise survey):

Who Should Buy the Elvex EP-412 Quattro?

Buy them if you want reusable flanged hearing protection with a retention cord at NRR 27 dB. Consider another plug if you need a different level or style: compare Uni-Fit, EP-411 Quattro, AirSoft. 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 Elvex EP-412 Quattro 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 27 plug you won’t lose between tasks.

Shooting & range use

For range and shooting use, pair a high NRR with muffs for impulse noise.

Elvex EP-412 Quattro Frequently Asked Questions

What is the NRR of the Elvex EP-412 Quattro?

The Elvex EP-412 Quattro are rated NRR 27 dB (EPA-labeled per ANSI S3.19). Real-world protection is usually lower, so NIOSH recommends derating the NRR when estimating exposure.

Are the Elvex EP-412 Quattro 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 Elvex EP-412 Quattro reusable or single-use?

They are reusable and washable across many shifts.

How do I insert the Elvex EP-412 Quattro?

To fit them, push the pre-molded flanges gently into the canal until sealed; no rolling needed. A proper seal is what delivers the rated protection.

Can I wash the Elvex EP-412 Quattro?

Yes — rinse the flanges with mild soap and water, dry, and reuse.

Are the Elvex EP-412 Quattro metal-detectable?

No. For food or pharma lines where a lost plug must be detectable, see our metal-detectable ear plugs.

What size are the Elvex EP-412 Quattro?

They are pre-sized flanges (check sizing if offered).

What noise levels suit NRR 27?

NRR 27 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 Elvex EP-412 Quattro NIOSH/EPA labeled?

Yes — NRR 27 dB is EPA-labeled under ANSI S3.19. WC Safety sells authentic Elvex hearing protection through legitimate channels.

Can I buy the Elvex EP-412 Quattro 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.
