Moldex 6630 Meteors Cordless Earplugs Overview

The Moldex 6630 Meteors Cordless Earplugs are cordless reusable flanged ear plugs from Moldex, rated NRR 28 dB. With no cord to catch or snag, they keep a low profile for tight and confined spaces — the most economical choice for high-volume single-use. Start with our hearing-protection guide and what NRR means, then confirm the noise level you’re protecting against.

The Moldex 6630 Meteors belong to the cordless ear plugs range. They are reusable and washable across many shifts; for the trade-offs see foam vs reusable ear plugs.

What NRR 28 dB Means

NRR is a laboratory rating; NIOSH suggests derating it for real-world use. Here is how NRR 28 dB lines up with common environments (always confirm with a noise survey):

Who Should Buy the Moldex 6630 Meteors?

Buy them if you want reusable flanged hearing protection in a low-profile uncorded design at NRR 28 dB. Consider another plug if you need a different level or style: compare 6430 Alphas, 6450 Jetz, 6598 BattlePlugs. 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 6630 Meteors 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 low-profile uncorded NRR 28 plug that won’t snag in tight spaces.

Shooting & range use

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

Yes — rinse, dry and reuse.

Plugs or muffs?

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

Moldex 6630 Meteors Frequently Asked Questions

What is the NRR of the Moldex 6630 Meteors?

The Moldex 6630 Meteors are rated NRR 28 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 6630 Meteors cordless?

Yes — uncorded for a low-profile fit with no cord to catch, and the most economical option for high-volume single-use.

Are the Moldex 6630 Meteors reusable or single-use?

They are reusable and washable across many shifts.

How do I insert the Moldex 6630 Meteors?

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 Moldex 6630 Meteors?

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

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

What size are the Moldex 6630 Meteors?

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

What noise levels suit NRR 28?

NRR 28 dB suits common industrial noise once derated; for very high or impulse noise, add earmuffs for dual protection. See what NRR means.

Are cordless ear plugs less protective than corded?

No. A cord is only for retention; an uncorded plug with the same body and seal delivers the same NRR.

Are the Moldex 6630 Meteors NIOSH/EPA labeled?

Yes — NRR 28 dB is EPA-labeled under ANSI S3.19. WC Safety sells authentic Moldex hearing protection through legitimate channels.

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.
