1. Introduction
The 3M E-A-Rsoft Yellow Neons 311-1251 Corded Earplugs are designed to provide effective hearing protection in noisy environments. These disposable earplugs feature soft, slow-recovery foam that seals the ear canal for excellent noise reduction. The corded design allows for convenient short-term storage around the neck when not in use.
2. Important Safety Information
For industrial/occupational use only. Not for consumer sale or use.
Please read and understand all instructions and warnings before using this product. Failure to follow these instructions may result in injury, sickness, or property damage.
- The Noise Reduction Rating (NRR) may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided.
- Misuse of 3M industrial and occupational products may result in injury, sickness, death, or property damage.
- Always select and use this product in compliance with applicable health and safety regulations and standards (e.g., U.S. OSHA, ANSI), as well as all product literature, user instructions, warnings, and other limitations.
- Consult your on-site safety professional, industrial hygienist, or other subject matter expert for product selection and use guidance.
3. Product Features

- Material: Soft, slow-recovery polyurethane foam for comfortable insertion and secure fit.
- Design: Tapered cylinder shape for easy roll-down and insertion.
- Size: Slightly longer than regular E-A-Rsoft earplugs to fit deeper into the ear canal, potentially offering higher noise reduction.
- Corded: Features a vinyl cord for easy short-term storage around the neck and to prevent loss.

4. How to Use Your 3M E-A-Rsoft Earplugs (Insertion & Removal)
Proper insertion is crucial for achieving the stated noise reduction. Follow these steps carefully:
- Roll Down: Slowly roll and compress the foam earplug into a very thin, crease-free cylinder.
- Insert: While compressed, insert the earplug well into the ear canal. For easier fitting, reach around the head to pull the ear outward and upward during insertion.
- Expand: Hold the earplug in place until it fully expands and you feel a secure seal. This may take a few seconds.
- Removal: To remove, gently twist the plug to break the seal and slowly pull it out. Do not remove abruptly.

5. Operating Guidelines
These earplugs are suitable for various industrial and occupational applications where noise exposure is a concern. Recommended applications include, but are not limited to: assembly and mechanical work, chipping, chiseling, cleaning, drilling, furnace operations, grinding, heavy equipment operations, machining, metal repair, painting, pouring/casting, power fastening, riveting, sanding, sawing, and welding.
For optimal performance and hygiene, use for a maximum of 4 hours at a time. Remember that the NRR should be reduced by 50% for a more realistic estimate of noise reduction in typical use.

6. Care and Cleaning
To maintain hygiene and effectiveness, follow these care instructions:
- Clean the earplugs after each use.
- Store earplugs in a clean, dry place when not in use. The poly bag packaging helps keep them clean prior to use.
- To clean, wash in mild liquid detergent and warm water. Squeeze out excess water and allow to fully air dry.
- Replace earplugs if they noticeably change their firmness, no longer re-expand to their original size and shape, or become permanently deformed.
7. Troubleshooting
- Earplugs not fitting securely: Ensure you have rolled the earplug into a sufficiently thin cylinder before insertion. Pulling the outer ear up and back during insertion can help open the ear canal for a deeper fit. Hold the earplug in place longer to allow full expansion.
- Insufficient noise reduction: Check for proper fit. If the earplugs are not fully expanded or seated correctly, noise reduction will be compromised. Re-insert following the instructions. If the issue persists, the earplugs may be damaged or worn, requiring replacement.
- Discomfort during use: Ensure the earplugs are not inserted too forcefully. The slow-recovery foam should expand gently. If discomfort persists, ensure the earplugs are clean and undamaged. If discomfort continues, discontinue use and consult a safety professional.
