Moldex SparkPlugs Metal Detectable PlugStation Earplugs Overview
The Moldex SparkPlugs Metal Detectable PlugStation Earplugs are uncorded, single-use, extra-soft foam earplugs with a Noise Reduction Rating of 33 dB, supplied in a sealed wall-mount dispenser. The foam contains a detectable element so a dropped plug can be caught before it reaches product.
As the Moldex 6655DIS, these SparkPlugs metal detectable earplugs are true metal detectable foam earplugs. The earplug dispenser station makes these NRR 33 detectable earplugs easy to grab clean at the entrance to a noisy area.
SparkPlugs use extra-soft, tapered foam that seals gently in the ear canal. Compare them with the reusable Howard Leight SmartFit detectable, see the field in best metal detectable ear plugs, and browse the range in metal detectable ear plugs.
Who These Earplugs Are For
| Use case | Fit | Buyer guidance |
|---|---|---|
| Food, beverage, or pharma lines | Purpose-built | Detectable foam for contamination control. |
| High-noise areas | Strong | NRR 33 tops the disposable range. |
| Shared entry-point dispensing | Strong | Sealed wall-mount PlugStation. |
| Reuse over single-use | Choose reusable | These are disposable; try a SmartFit. |
| Tethered plugs for drop control | Consider corded | These are uncorded. |
Treat the NRR as a starting point, not a promise. The SparkPlugs NRR of 33 dB is a laboratory rating, and real-world attenuation is typically lower because few workers get the perfect seal achieved in a test lab, so NIOSH recommends derating the number when you estimate on-the-job protection. The rated protection only happens with a correct roll-down and full insertion, so train workers to fit and check a foam plug. Where noise exposure reaches the OSHA action level, an earplug does not replace a hearing-conservation program with exposure monitoring, training, and audiometric testing under 29 CFR 1910.95. Learn the basics in what is NRR explained and OSHA 1910.95 hearing conservation.
Pros & Cons
Pros
- Detectable foam for food and pharma lines
- NRR 33, top of the disposable range
- Extra-soft tapered foam for comfort
- Sealed wall-mount dispenser keeps plugs clean
- Grab-a-fresh-pair hygiene at entry points
Cons
- Single-use; not reusable
- Uncorded, so not tethered against drops
- Pair count not stated in the listing title
- Foam needs correct roll-down to seal
How It Compares
The SparkPlugs detectable is a disposable dispenser plug. Weigh it against nearby choices:
| Option | Type | NRR | Best for |
|---|---|---|---|
| Moldex SparkPlugs detectable (this page) | Disposable foam, uncorded, dispenser | 33 | High-noise food/pharma lines |
| Howard Leight SmartFit detectable | Reusable, corded | 25 | Reuse and contamination control |
| Standard SparkPlugs foam | Disposable foam | 33 | General high-noise, non-detectable |
Choose the SparkPlugs detectable for high-noise detectable disposables, the reusable Howard Leight SmartFit where reuse matters, or browse NRR 33 ear plugs. See highest NRR ear plugs, best foam ear plugs, and disposable vs reusable.

Frequently Asked Questions
What is the NRR of the Moldex SparkPlugs metal detectable earplugs?
They carry a Noise Reduction Rating of 33 dB, which is the highest common rating for a disposable foam earplug. That is the laboratory value, and real-world protection is usually lower, so NIOSH suggests derating the NRR when you estimate protection for a noisy task.
What makes them metal detectable?
The foam contains a detectable element, so if a plug is dropped it can be picked up by metal-detection equipment on a production line. This helps a lost plug get caught before it contaminates food, beverage, or pharmaceutical product.
What is a PlugStation?
A PlugStation is a sealed, wall-mount dispenser that holds many pairs of earplugs and dispenses one pair at a time. The seal keeps the plugs clean and sanitary, and the wall mount puts protection where workers enter a noisy area.
How many pairs are in the dispenser?
The exact number of pairs is not stated in the listing title, and we do not publish a count we cannot verify. Check the current product page for the pair count so you know how long a station will last for your team.
Are they corded or uncorded?
The SparkPlugs PlugStation dispenses uncorded plugs. Uncorded plugs suit a shared dispenser and reduce snag hazards, but they are not tethered, so a metal-detectable design is especially useful for catching a dropped plug.
Are they reusable?
No. SparkPlugs are single-use disposable foam earplugs. Discard them after use rather than washing and reinserting them, and take a fresh pair from the dispenser each time to keep protection and hygiene consistent.
What are they made of?
They are made of extra-soft, extra-light foam with a tapered shape that fits easily into the ear canal and seals gently without excess pressure. The softness is meant to improve all-day comfort in loud environments.
How do I insert a foam earplug correctly?
Roll the plug down tight with clean hands, reach over your head to pull the ear up and out, insert the plug well into the canal, and hold it until it expands to seal. A proper seal is what delivers the rated protection.
Are they good for very high noise?
NRR 33 is the top of the common disposable range, so they suit high-noise areas. For extreme noise you may combine plugs with earmuffs, but dual protection does not simply add the two ratings; base the choice on your measured noise levels.
Do I still need a hearing program if workers use these?
Yes. Where noise exposure reaches OSHA action levels, the employer must run a hearing-conservation program with exposure monitoring, training, and audiometric testing. The right earplug is one part of that program, not a replacement for it.
Where should I mount the PlugStation?
Mount it at the entrance to a noisy area or a shared work zone so workers can grab a fresh pair before exposure. Keep it stocked and clean, and pair it with signage that hearing protection is required.
Are they suitable for food processing?
That is the main purpose of the metal-detectable version. The detectable foam and dispenser support food, beverage, and pharmaceutical settings where a dropped plug must be detectable. Confirm they fit your facility's detection and HACCP requirements.
