3M E-A-Rsoft Yellow Neons Earplugs – Soft, Comfortable Hearing Protection for High-Noise Environments
3M E-A-Rsoft Yellow Neons 312-1250 uncorded foam earplugs offer a tapered, slow-recovery foam design for industrial hearing protection. Each pair is poly-bagged for distribution, and ASA supplies 200 pairs per box—400 individual earplugs. The uncorded format eliminates a connecting cord for workplaces that restrict loose cords near equipment.
NRR clarification: 3M’s U.S. page displays 33 dB in its rating field, but its detailed guidance specifies 32 dB for regular size alone and 33 dB for regular and large sizes in combination. Model 312-1250 is regular size. Consult the supplied labeling and manufacturer guidance when selecting protection.

Key Features
- Soft polyurethane foam with a tapered profile.
- Slow recovery allows time for insertion after rolling.
- Neon yellow color makes earplug use visible.
- Pairs packaged in poly bags for workplace distribution.
Common Uses & Applications
- Construction, manufacturing and automotive work.
- Metalworking, grinding and equipment maintenance.
- Warehouses and industrial plants with assessed noise hazards.
Where the noise assessment calls for dual protection, pair suitable earplugs with earmuffs. Do not add their individual NRR values together to estimate combined protection.
Fitting & Daily Use
With clean hands, roll the earplug into a narrow, crease-free cylinder. Pull the ear upward and outward, insert the compressed foam and hold it until it expands. Follow the manufacturer’s complete instructions and check both ears. If you cannot obtain a comfortable seal, try another size or protector with your safety professional.
Put hearing protection on before entering hazardous noise and keep it fitted throughout exposure. Replace dirty, damaged or dropped plugs as appropriate. Keep unopened pairs clean and dry. Bright color confirms visibility, not the quality of the seal or the wearer’s personal attenuation.
Workplace Hearing Conservation
OSHA 29 CFR 1910.95 requires a hearing conservation program in general industry at exposures reaching an eight-hour time-weighted average of 85 dBA. Employers must evaluate attenuation and ensure proper fitting and training. This regulation is not an individual product certification.
NIOSH hearing protection guidance recommends individual fit testing. Actual protection can be lower than laboratory ratings. 3M E-A-Rfit testing requires the appropriate validation equipment and probed test plugs.
Manufacturer Documentation

The 3M Yellow Neons technical datasheet (Australia/New Zealand PDF) includes this model and fitting guidance. Its regional SLC80 rating is different from U.S. NRR.
FAQ
Are these metal-detectable earplugs?
No. Standard 312-1250 is not metal detectable. Facilities with detection requirements need a separately documented model.
How many pairs are supplied?
ASA lists 200 pairs per box. Specify pairs when comparing prices and planning supplies for workers and visitors.
