Protecting your hearing at a noisy job site depends on more than choosing an earplug with a high rating. Fit, comfort, correct insertion, and having enough plugs available for your crew all matter. The 3M E-A-Rsoft Yellow Neon Blasts 391-1010 combines soft disposable foam with a 500-pair refill format and a listed Noise Reduction Rating (NRR) of 33 dB. This review explains where the refill works well, how to fit the plugs correctly, and why the dispenser requirement and workplace-use guidance deserve attention before you buy.
Quick Verdict
Rating: 8.8/10, recommended with caveats
Best For: Workplaces that already use a 3M One Touch dispenser and need a bulk supply of disposable foam hearing protection.
Bottom Line: The soft, slow-recovery foam and 33 dB NRR make this a strong option for demanding industrial noise environments when the plugs fit correctly. The main tradeoffs are that they are disposable and this 391-1010 product is a refill designed around the 3M One Touch dispensing system.

Key Takeaways
- The 391-1010 refill contains 500 pairs of disposable, uncorded foam earplugs for the 3M One Touch dispensing system.
- Its listed 33 dB NRR is suitable for high-noise workplace applications, but actual protection depends heavily on correct fit and insertion.
- Soft, slow-recovery polyurethane foam gives you time to compress and insert the plug before it expands inside the ear canal.
- The regular-size plugs use high-visibility yellow coloring, making workplace compliance checks easier.
- These plugs are not reusable. Replace used or contaminated plugs rather than washing them for repeated use.
What Is the 3M E-A-Rsoft Yellow Neon Blasts 391-1010?
The 3M E-A-Rsoft Yellow Neon Blasts 391-1010 is a bulk refill of uncorded roll-down foam earplugs. One refill bottle contains 500 pairs and is designed for use with the 3M One Touch Pro Earplug Dispenser. That format is particularly useful when many workers need quick access to hearing protection at a central safety station.
Each plug is made from slow-recovery polyurethane foam. You roll the foam down, insert it into the ear canal, and hold it while the material expands. The expanding foam creates the seal needed for effective attenuation and also spreads pressure across the ear canal for a more comfortable fit.
This is an industrial and occupational hearing-protection product rather than a general lifestyle earplug. You should select and use it according to 3M instructions, workplace safety requirements, and your employer’s hearing-conservation procedures.
Who Should Buy It?
Best For
- Workplaces already using a 3M One Touch Pro dispensing system.
- Welding, grinding, machining, drilling, construction, and similar high-noise operations.
- Teams that need a convenient bulk supply of disposable foam earplugs.
Skip If
- You specifically want washable or reusable hearing protection.
- You need a corded earplug that is harder to misplace between tasks.
- You are buying for a non-occupational application that is outside the manufacturer’s intended use.
Before You Buy: Model 391-1010 is a 500-pair refill bottle associated with the 3M One Touch dispensing system. Check what your workplace already has before ordering, and remember that these foam earplugs are disposable rather than washable reusable plugs.
Noise Reduction and Hearing Protection
The main performance specification is the 33 dB Noise Reduction Rating. That is a strong labeled attenuation value for disposable foam earplugs, which is one reason this model is suited to loud industrial operations such as drilling, grinding, machining, sawing, and welding.
You should not interpret an NRR of 33 dB as a guarantee that every wearer will experience exactly 33 dB of real-world reduction. A poorly inserted plug can leave a substantial gap between laboratory-rated attenuation and the protection you actually receive.
3M strongly emphasizes proper fitting and individual fit testing. Model 391-1010 is compatible with the 3M E-A-Rfit Validation System, which can help workplace safety teams evaluate the protection achieved by an individual wearer.
Foam Comfort and Fit
The slow-recovery polyurethane foam is one of the strongest reasons to choose this style. Once you compress the plug into a narrow cylinder, the foam does not immediately spring back to full size. That gives you enough time to position it correctly inside the ear canal.
After insertion, the material gradually expands to form a seal. The soft foam is intended to apply relatively low pressure, which can make the plugs more comfortable during longer work periods than a poorly fitting rigid protector.
Comfort is still personal. This is the regular-size version, so workers with unusually small or large ear canals may need another size or hearing-protection style. A plug that causes pain, repeatedly works loose, or cannot create an effective seal should not be forced to work.
One Touch Refill Design and Workplace Convenience
A 500-pair bottle makes more sense for a shop, plant, fabrication area, or job site than for someone who needs only a few pairs. When paired with a compatible One Touch dispenser, workers can access uncorded plugs from a central location without handling a box full of individually packaged pairs.
The high-visibility yellow color also helps supervisors identify whether hearing protection is being worn. The Yellow Neon Blasts version adds red/orange flame-style graphics while retaining the bright base color.
The large refill quantity can reduce how often your safety station needs restocking. On the other hand, you get the best value from this package only when your workplace uses disposable plugs frequently enough to justify a 500-pair supply.
Where These Earplugs Make the Most Sense
The 391-1010 design fits environments where noise changes throughout the workday and disposable hearing protection must remain easy to access. Manufacturing, construction, fabrication, metalworking, machining, and heavy-equipment operations are practical examples.
For welding and grinding, the compact in-ear design keeps the hearing protector out of the way of many helmets, face shields, and other protective equipment. You still need to confirm that your complete PPE setup works together correctly and does not interfere with the fit of any required protective equipment.
In workplaces with several employees, the refill-and-dispenser format also simplifies distribution. Each worker can take a fresh pair when needed instead of storing and reusing contaminated disposable plugs.
How to Properly Insert the Earplugs
Correct insertion is critical because even a high-NRR foam plug loses effectiveness when it sits too loosely in your ear. Follow the instructions supplied by 3M and your workplace hearing-protection program.
- Start with clean hands. Avoid transferring dirt, oil, or other contamination onto the foam before insertion.
- Roll the plug down. Compress the foam into a narrow, crease-free cylinder using your fingers.
- Open the ear canal. Reach over your head with your opposite hand and gently pull the outer ear up and back.
- Insert the compressed plug. Place it far enough into the ear canal to form an effective seal without forcing it painfully.
- Hold it while it expands. Keep a finger on the plug until the slow-recovery foam expands and stays securely in position.
- Check the fit. Both plugs should feel secure, and surrounding noise should noticeably decrease. Workplace fit testing provides a better assessment than comfort alone.
Pro Tip: Rolling the foam into a smooth, narrow cylinder usually works better than simply squeezing the end. Creases can make insertion harder and may prevent the plug from sealing evenly.
How It Performs in Real Use
For Welding and Fabrication
During welding, cutting, and fabrication work, the in-ear design keeps the hearing protector compact around helmets and other head-mounted PPE. The disposable format is also useful in dirty work areas because you can replace contaminated plugs instead of trying to preserve one pair indefinitely.
For Grinding and Machining
Grinding and machining can produce sustained noise where consistent hearing protection matters. The 33 dB NRR gives this model a strong labeled attenuation level, but your actual protection still depends on obtaining a proper seal every time you insert the plugs.
For Shared Work Areas
The 500-pair refill becomes especially practical when several employees need access throughout a shift. A compatible dispenser can provide a central hearing-protection point near shop entrances, PPE stations, or other designated areas.
For Extended Shifts
Soft slow-recovery foam can reduce the pressure discomfort associated with harder materials. You should still remove and replace a plug if it becomes dirty, damaged, uncomfortable, or cannot maintain an effective fit.
Material Safety, Hygiene, and Workplace Use
These earplugs are made from polyurethane foam and are designed as disposable hearing protection. The practical hygiene approach is therefore to use a fresh pair rather than washing used plugs and putting them back into service.
Keep unused plugs protected from contamination and damaging storage conditions. Do not use plugs that are visibly dirty, damaged, degraded, or unable to expand and seal normally.
3M identifies this product for industrial and occupational use. Hearing-protection selection should account for the actual noise exposure, required regulations, fit, communication needs, and other PPE being worn. If you are responsible for workplace hearing protection, follow applicable safety requirements and consult a qualified safety professional or industrial hygienist when necessary.
Pros and Cons
Pros
- 33 dB NRR provides a strong labeled attenuation level.
- Soft, slow-recovery polyurethane foam supports comfortable roll-down fitting.
- 500-pair refill works well for busy workplaces with frequent earplug use.
- Compatible with the 3M One Touch Pro dispensing system.
- High-visibility coloring helps with workplace compliance checks.
Cons
- Disposable design means used plugs should not be washed for repeated use.
- The 500-pair quantity may be excessive for a very small operation.
- Rated attenuation depends on correct insertion and fit, so the NRR alone cannot guarantee your real-world protection.
Is It Worth the Price?
The 3M 391-1010 makes the most financial sense as a bulk workplace supply. You receive 500 pairs in one refill bottle, so the value comes from serving multiple employees or supporting frequent disposable-earplug use rather than buying a small quantity for occasional tasks.
It is worth considering if your facility already uses a 3M One Touch dispenser and you value a high NRR, recognizable brand, soft foam, and fast access to fresh earplugs. The package is less compelling when you need only occasional hearing protection or prefer a reusable product.
Do not judge value by quantity alone. Properly fitted hearing protection that employees will actually wear is more useful than a higher-spec product that is uncomfortable or repeatedly fitted incorrectly.
How It Compares to Alternatives
Within 3M’s refill range, the E-A-Rsoft Yellow Neons 391-1004 is another regular-size polyurethane foam option for the One Touch system. The E-A-Rsoft FX 391-1012 is a large-size alternative, while the 3M 1100 refill 391-1100 uses a different 3M foam-earplug design and carries a lower listed NRR.
The 391-1010 makes the most sense when you specifically want the regular-size Yellow Neon Blasts style, 500-pair refill packaging, and One Touch compatibility. Fit should take priority over small differences in appearance or product family.
Frequently Asked Questions
Are 3M 391-1010 earplugs reusable?
No. The 3M E-A-Rsoft Yellow Neon Blasts 391-1010 plugs are listed as non-reusable disposable foam earplugs. Replace used, dirty, damaged, or contaminated plugs rather than washing them for repeated use.
How many pairs are in the 391-1010 refill?
The refill bottle contains 500 pairs. That large quantity is designed primarily for workplace dispensing and other environments where disposable earplugs are used regularly.
Do you need a 3M One Touch dispenser?
Model 391-1010 is sold as a One Touch refill bottle and is designed around the 3M One Touch Pro dispensing system. Check your existing PPE station and the current product package before ordering so you know exactly which components you need.
Does an NRR of 33 dB mean noise is always reduced by 33 dB?
No. NRR is a laboratory-based attenuation rating and does not guarantee identical protection for every wearer. Your fit, insertion technique, ear anatomy, and workplace conditions can all affect the protection you actually receive.
What material are these earplugs made from?
The earplugs use polyurethane foam. It is a slow-recovery material that can be rolled into a narrow cylinder for insertion and then expands inside your ear canal to create the seal.
How can you tell if a foam earplug is fitted correctly?
A properly fitted plug should remain secure after the foam expands and should produce a noticeable reduction in surrounding sound. For occupational hearing protection, personal fit testing and your employer’s safety procedures provide a more reliable check than comfort alone.
Can you use these earplugs for welding and grinding?
Welding, grinding, drilling, machining, and similar industrial operations are appropriate examples of the noisy work environments for which this type of hearing protection is intended. Your workplace still needs to select protection according to measured exposure, applicable safety requirements, fit, and the other PPE you use.
The Bottom Line
The 3M E-A-Rsoft Yellow Neon Blasts 391-1010 is a strong choice for workplaces that need a 500-pair supply of soft, disposable foam earplugs for a compatible One Touch dispensing system. Its key strengths are the 33 dB NRR, slow-recovery polyurethane foam, and workplace-friendly refill format, while its main limitations are the disposable design and the importance of correct fit.
You should skip it if you need washable reusable hearing protection or only need a small number of plugs. For regular industrial use with proper fitting and workplace safety procedures, it earns our 8.8/10 recommended-with-caveats verdict.
