Moldex 6970 Meteors Review: Corded — 100-pair box NRR 33
Moldex 6970 Meteors Corded NRR 33 — High-Visibility Tethered Earplugs for FOD-Prevention and Cord-Mandate Industrial Programs
The Moldex 6970 Meteors Corded adds a connecting tether cord to the same NRR 33 high-visibility lime foam of the Moldex 6870 Meteors, making it the standard-size bell-shaped Meteors solution for facilities with FOD (foreign object debris) prevention requirements or cord-mandate hearing protection policies. This review covers the 6970's cord design, NIOSH approval, OSHA 29 CFR 1910.95 compliance, NRR 33 attenuation, comparison across the Meteors family, and when to choose corded over uncorded protection.
Editorial Verdict — 4.3 / 5
The Moldex 6970 is the corded variant of Moldex Meteors — same NRR 33 ultra-soft lime bell-shaped foam, with a connecting cord that prevents earplug loss into product streams or machinery. High-visibility lime combined with a cord eliminates both loss-into-product and non-wear compliance issues simultaneously. For uncorded Meteors, see Moldex 6870. For metal-detectable cord programs, see Moldex 6615 SparkPlugs MD.
Pros
- NRR 33 — maximum NIOSH foam earplug rating
- Tether cord — prevents earplug loss into product streams, satisfies cord-mandate policies
- High-visibility lime — confirms wear compliance from distance during OSHA HCP walk-throughs
- Bell-shaped foam — tapered tip eases insertion in both corded and uncorded format
- Made in USA (Covina, California)
- NIOSH approved under 42 CFR Part 84
Cons
- 100 pairs per box vs. 200 for uncorded 6870 — higher per-box cost
- Cord can snag in machinery — not appropriate for all industrial environments
- No metal-detectable variant — use Moldex 6615 for food/pharma FOD programs
- Standard size only — narrow canals need Moldex 6632 Meteors Small Corded

FOD Prevention: Why Corded Earplugs Matter in Industrial Settings
FOD (foreign object debris) prevention programs are standard in aerospace manufacturing, automotive assembly, food processing, and any facility where small objects entering machinery or product streams create safety or quality hazards. Uncorded earplugs — including the Moldex 6870 Meteors, Moldex 6608 Camo Plugs, and Moldex 6620 Goin' Green — present FOD risk if an earplug falls from a worker's ear and enters a product stream or machinery without detection.
The cord of the Moldex 6970 ensures that both plugs remain tethered to each other and, when not in use, can be worn around the neck. If a plug works loose during work, the cord prevents it from falling into machinery or product. Note: the 6970 cord is not metal-detectable. For food and pharmaceutical manufacturing where metal detection is required, the Moldex 6615 SparkPlugs Metal Detectable Corded is the appropriate product.

| Workplace TWA | OSHA 50% Derating | Effective Exposure | OSHA Compliant? |
|---|---|---|---|
| 85 dB(A) | −13 dB(A) | 72 dB(A) | Yes |
| 90 dB(A) | −13 dB(A) | 77 dB(A) | Yes |
| 100 dB(A) | −13 dB(A) | 87 dB(A) | Yes |
| 103 dB(A) | −13 dB(A) | 90 dB(A) | Yes (OSHA PEL limit) |

Corded vs. Uncorded: When to Specify Moldex 6970 vs. 6870
Both the Moldex 6970 Corded and Moldex 6870 Uncorded achieve NRR 33 with the same bell-shaped lime foam. The decision between them is driven by facility policy, not attenuation performance:
| Scenario | Recommended Variant |
|---|---|
| Standard industrial — no cord policy | Moldex 6870 Uncorded (200 pairs/box) |
| FOD-prevention required — non-MD | Moldex 6970 Corded (100 pairs/box) |
| Food/pharma — metal detection required | Moldex 6615 SparkPlugs MD Corded |
| Narrow ear canals — FOD required | Moldex 6632 Meteors Small Corded |
| Eco-conscious — corded required | Moldex 6622 Goin' Green Corded |
Frequently Asked Questions: Moldex 6970 Meteors Corded NRR 33
Q: What is the NRR of the Moldex 6970 Meteors Corded?
A: The Moldex 6970 has an NRR of 33 dB, identical to the uncorded Moldex 6870. The cord does not affect attenuation. Effective protection per OSHA 50% derating is approximately 13 dB(A).
Q: Why does the Moldex 6970 have a cord?
A: The cord prevents earplug loss into product streams or machinery — essential for FOD-prevention programs. It also allows workers to wear the plugs around the neck when temporarily removed, reducing loss and ensuring hearing protection is always at hand.
Q: Is the Moldex 6970 cord metal-detectable?
A: No. The Moldex 6970 cord is not metal-detectable. For food processing or pharmaceutical facilities requiring metal-detectable corded earplugs, use the Moldex 6615 SparkPlugs Metal Detectable Corded.
Q: How does the Moldex 6970 differ from the Moldex 6870?
A: Both the Moldex 6970 and Moldex 6870 use the same NRR 33 bell-shaped lime foam. The 6970 adds a connecting cord; the 6870 does not. The 6870 comes in 200-pair boxes; the 6970 in 100-pair boxes.
Q: Is the Moldex 6970 NIOSH approved?
A: Yes. The Moldex 6970 is NIOSH approved under 42 CFR Part 84 / 29 CFR 11.57.
Q: Are Moldex 6970 Meteors Corded made in the USA?
A: Yes. The Moldex 6970 is manufactured in Covina, California.
Q: Is there a smaller-diameter corded Meteors for narrow ear canals?
A: Yes. The Moldex 6632 Meteors Small Corded provides the same bell-shaped profile in a smaller diameter with cord, at NRR 28, for workers with narrower ear canal anatomy.
Q: Can cords snag in machinery?
A: Yes — cord safety must be evaluated for each application. In environments with rotating machinery, pinch points, or conveyor systems, dangling cords can pose an entanglement hazard. Consult your facility's hazard assessment before specifying corded earplugs in those areas.
Q: How does high-visibility lime help with OSHA hearing conservation compliance?
A: OSHA 29 CFR 1910.95 requires employers to enforce hearing protector use. The lime color of the Moldex 6970 makes worn earplugs visible at distance, enabling supervisors to verify compliance during walk-throughs without approaching individual workers.
Q: What OSHA noise exposure level triggers mandatory hearing protection?
A: OSHA 29 CFR 1910.95 sets the action level at 85 dB(A) TWA and the PEL at 90 dB(A) TWA. The Moldex 6970 NRR 33 reduces effective exposure by approximately 13 dB(A), covering exposures up to 103 dB(A) TWA within single-protector compliance limits.
Q: What is the standard that governs the NRR 33 rating for the Moldex 6970?
A: ANSI/ASA S3.19, referenced by EPA 40 CFR Part 211, Subpart B. OSHA uses this rating with 50% derating for compliance calculations under 29 CFR 1910.95.
Q: How does the Moldex 6970 compare to the Moldex 6622 Goin' Green Corded?
A: Both are NRR 33 corded foam earplugs in 100-pair boxes, Made in USA. The Moldex 6970 has a bell-shaped lime body optimized for easy insertion and compliance visibility. The Moldex 6622 Goin' Green Corded uses PVC-free, dye-free cylindrical foam suited for eco-certified and LEED worksites.
Q: How does the Moldex 6970 compare to the Moldex 6609 Camo Plugs Corded?
A: Both are NRR 33 corded, 100-pair. The Moldex 6970 Meteors Corded has a bell-shaped lime body for easy insertion and high-visibility compliance monitoring. The Moldex 6609 Camo Plugs Corded has a cylindrical body with camouflage pattern preferred in construction demographics.
Q: Can I use dual hearing protection with the Moldex 6970?
A: Yes. For noise above 103 dB(A) TWA, combine the Moldex 6970 with compatible earmuffs from the WC Safety hearing protection collection. Add 5 dB to the higher NRR value per OSHA guidance.
Q: Where can I buy Moldex 6970 Meteors Corded earplugs?
A: The Moldex 6970 is available at WC Safety with industrial pricing. Also available on Check Price on Amazon →.
