3M E-A-Rsoft Yellow Neons Metal Detectable Earplugs Overview
The 3M E-A-Rsoft Yellow Neons Metal Detectable Earplugs (311-4106) are corded, single-use polyurethane foam earplugs with a Noise Reduction Rating of 33 dB, and 3M lists 32 dB for the regular size alone. A stainless-steel bead in the plug and metallic powder in the cord make both detectable.
As the 3M 311-4106, these E-A-Rsoft metal detectable earplugs are true metal detectable corded earplugs. Built as detectable foam earplugs, they work as NRR 33 detectable earplugs for lines that must catch a lost plug.
The slow-recovery tapered foam gives time to insert the plug before it expands to seal. Compare them with the disposable Moldex SparkPlugs detectable and 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 plug and cord. |
| High-noise areas | Strong | NRR 33 tops the disposable range. |
| Drop control with a cord | Strong | Corded, and the cord is detectable. |
| Reuse over single-use | Choose reusable | These are disposable foam. |
| Uncorded preference | Different SKU | This model is corded. |
Treat the NRR as a starting point, not a promise. The 33 dB rating (32 dB for the regular size alone) is a laboratory value, 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, slow expansion in the canal, 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 plug and detectable cord
- NRR 33, top of the disposable range
- Slow-recovery foam for an easy fit
- High-visibility yellow for inspection
- Corded to reduce dropped plugs
Cons
- Single-use; not reusable
- Regular size only; 32 dB alone
- Pack size varies by seller
- Foam needs correct roll-down to seal
How It Compares
The Yellow Neons detectable is a corded disposable plug. Weigh it against nearby choices:
| Option | Type | NRR | Best for |
|---|---|---|---|
| 3M Yellow Neons detectable (this page) | Disposable foam, corded | 33 (32 regular) | High-noise food/pharma lines |
| Moldex SparkPlugs detectable | Disposable foam, dispenser | 33 | Uncorded dispenser format |
| Howard Leight SmartFit detectable | Reusable, corded | 25 | Reuse and contamination control |
Choose the Yellow Neons detectable for high-noise corded disposables, the Moldex SparkPlugs for a dispenser, or the reusable Howard Leight SmartFit where reuse matters. See highest NRR ear plugs, best foam ear plugs, and disposable vs reusable.

Frequently Asked Questions
What is the NRR of the 3M E-A-Rsoft Yellow Neons metal detectable?
It carries a Noise Reduction Rating of 33 dB, and 3M lists 32 dB for the regular size alone. 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?
A stainless-steel bead is implanted in the foam plug and the recycled PVC cord contains metallic powder, so both the plug and the cord are detectable. If a plug or cord is dropped, metal-detection equipment can catch it before it contaminates food or product.
Are they corded?
Yes, this model, 311-4106, is the corded version, and the cord is metal detectable too. A cord lets the plugs hang around the neck when not in use, which helps prevent loss and keeps a removed plug out of the product stream.
Are they reusable?
No. These are single-use disposable foam earplugs. Discard them after use rather than washing and reinserting, and take a fresh pair each time to keep protection and hygiene consistent.
What is slow-recovery foam?
The polyurethane foam recovers slowly after you roll it down, which gives you time to insert the compressed plug fully into the ear canal before it expands to seal. A full, slow expansion is what delivers the rated protection.
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. Check that it feels sealed and that outside noise is noticeably muffled.
How many pairs come in a box?
3M supplies the 311-4106 in bulk, and pack sizes vary by seller, commonly 200 pairs per box up to 2000 pairs per case. Confirm the exact pack on the product listing so you know how long it will last.
Are they good for very high noise?
NRR 33 is at 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.
Are they suitable for food processing?
That is exactly what metal-detectable earplugs are made for. The detectable plug and cord and the high-visibility yellow color support food, beverage, and pharmaceutical settings where a dropped plug must be detectable. Confirm they fit your detection and HACCP requirements.
What size are they?
The 311-4106 is a regular-size tapered foam plug that fits most ear canals. If a worker cannot get a comfortable seal, try a different size or shape and confirm the fit, since a poor seal cuts the real protection.
How are they different from a reusable detectable plug?
These are single-use foam with a higher NRR, while a reusable detectable plug like a triple-flange is washable and lasts longer at a lower NRR. Choose disposable foam for the highest attenuation, or reusable where reuse and lower waste matter more.
