Moldex SparkPlugs Corded Foam Earplugs – NRR 33 dB Hearing Protection
Moldex SparkPlugs 6654 corded earplugs combine soft, tapered foam with an attached cord that keeps the pair together between tasks. Their colored streaks and swirls identify the SparkPlugs design, while low-pressure foam provides a comfortable option for industrial hearing protection. Each box contains 100 corded pairs.
The NRR 33 dB rating is based on laboratory attenuation testing under ANSI S3.19-1974. Actual protection depends on fit and consistent wear. Select these disposable foam earplugs using the workplace noise assessment rather than assuming their rating guarantees protection for every task.

NRR 33 dB
Key Features
- Soft, tapered foam with a smooth surface.
- Attached cord helps keep the earplugs together.
- PVC-free construction with multicolored streaks and swirls.
- Disposable format for routine workplace replenishment.
Common Uses & Applications
- Manufacturing, metal fabrication and industrial maintenance.
- Construction, automotive service and landscaping.
- Warehouse equipment areas with assessed noise hazards.
Coordinate hearing protection with safety glasses and eye protection selected for the same task. Each PPE item must address its identified hazard.
Fit, Cord Safety & Care
With clean hands, compress the tapered end into a narrow, wrinkle-free cylinder. Pull the ear upward and outward, insert the compressed plug and hold it while the foam expands. Follow Moldex’s complete foam earplug fitting instructions. These are roll-down plugs, not push-in plugs.
Assess cord entanglement hazards around moving machinery before selecting this version. Removing the plugs during hazardous noise exposure interrupts protection; resting them around the neck is appropriate only outside that exposure. Replace soiled or damaged plugs and keep unused supplies clean and dry.
Buying Guide
Record model 6654 and the 100-pair box quantity on repeat orders. For work requiring no connecting cord, compare Moldex SparkPlugs 6604 uncorded earplugs. Standard 6654 is not the metal-detectable SparkPlugs version; facilities requiring detectable PPE need the appropriate separate model.
Applicable Standards & Hearing Conservation
OSHA 29 CFR 1910.95 requires a hearing conservation program in general industry when exposure reaches an eight-hour time-weighted average of 85 dBA. Employers must evaluate attenuation and provide proper fitting and training. This is an employer obligation, not an OSHA product certification.
NIOSH hearing protection guidance supports individual fit testing. Do not simply subtract the NRR from measured workplace noise to predict a worker’s exposure.

FAQ
Does the cord make these reusable earplugs?
No. The cord joins the pair; it does not change the disposable foam construction.
Can bright colors confirm correct fit?
No. Visibility can help identify earplug use, but it cannot establish an adequate seal or the wearer’s personal attenuation.
