Cordova Encore Corded Earplugs Overview

The Cordova Encore Corded Earplugs are corded single-use foam ear plugs from Cordova, 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. Start with our hearing-protection guide and what NRR means, then confirm the noise level you’re protecting against.

The Cordova Encore 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 Cordova Encore?

Buy them if you want single-use foam hearing protection with a retention cord at NRR 33 dB. Consider another plug if you need a different level or style: compare E-A-Rsoft SuperFit 311-1254, E-A-Rsoft FX 312-1274, 6881 SparkPlugs. 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 Cordova Encore 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.

Shooting & range use

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

Cordova Encore Specifications

Fit & Sizing

The Cordova Encore 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.

Cordova Encore Frequently Asked Questions

What is the NRR of the Cordova Encore?

The Cordova Encore 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 Cordova Encore 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 Cordova Encore reusable or single-use?

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

How do I insert the Cordova Encore?

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 Cordova Encore?

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

Are the Cordova Encore 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 Cordova Encore?

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 Cordova Encore NIOSH/EPA labeled?

Yes — NRR 33 dB is EPA-labeled under ANSI S3.19. We link only to authentic Cordova hearing protection from reputable Amazon sellers.

Can I buy the Cordova Encore 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.
