3M E-A-Rsoft Yellow Neons 312-1250 NRR 33 Foam Ear Plugs — Uncorded, 200-Pair Box Overview
The 3M E-A-Rsoft Yellow Neons 312-1250 are uncorded, slow-recovery polyurethane foam ear plugs rated NRR 33 (ANSI S3.19) — among the highest noise reduction ratings available for any in-ear protector. This listing is the 200-pair bulk box, built for facilities that issue fresh single-use plugs every shift. The hi-vis yellow body makes compliance checks fast on the floor: a supervisor can confirm plugs are in at a glance.
Be realistic about the number. The NRR 33 on the label is a laboratory figure. Real-world attenuation is lower and depends entirely on fit. OSHA's standard derate for estimating field protection is (NRR − 7) / 2, which puts the 312-1250 at roughly 13 dB of usable reduction. NIOSH recommends derating foam plugs by 25% (about 25 dB here). Use those adjusted numbers — not the 33 — when comparing your measured exposure to OSHA's 85 dBA action level and 90 dBA PEL under OSHA 1910.95 hearing conservation. If you are unsure how much attenuation your noise level actually requires, see what is NRR and our guide on how to calculate the NRR you need.
Because these are uncorded and disposable, they suit clean-handed assembly, packaging, and general plant work where a cord is a snag hazard. For roll-down technique that actually delivers rated attenuation, follow how to insert foam earplugs. Browse more options in NRR 33 ear plugs or the full hearing protection range.
What It Is Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| Issuing daily plugs to a crew (high noise) | Excellent | 200-pair box covers a crew for weeks; NRR 33 is the top tier for foam plugs. Fresh pair each shift. |
| Sustained exposure above 95 dBA | Strong | Highest available foam NRR. Confirm derated attenuation (OSHA ~13 dB, NIOSH ~25 dB) clears your measured dBA; dual protection if needed. |
| Clean-handed assembly / packaging / general plant | Excellent | Uncorded design avoids snag points; soft foam is comfortable for full shifts. |
| Dirty work where hands re-touch plugs (welding, grinding) | Limited | Uncorded plugs must be handled to insert; a corded foam plug keeps them out of the dirt between uses. |
| Frequent in/out (intermittent noise areas) | Limited | Single-use foam isn't made for repeated reinsertion; consider a reusable flanged or corded plug instead. |
| Reusable, washable protection | Not suited | These are disposable. For washable plugs see our reusable range. |
Earplugs reduce noise, but the labeled NRR is a laboratory number — real-world protection is lower. NIOSH derates foam by about 25%, and OSHA estimates protection as (NRR − 7) ÷ 2. Under OSHA 29 CFR 1910.95 a hearing-conservation program is required at an 8-hour TWA of 85 dBA. Insert foam plugs correctly (roll, pull the ear up and back, hold) for the rated seal, and use dual protection with earmuffs in very high noise. See how to calculate the NRR you need.
Pros & Cons
Pros
- NRR 33 (ANSI S3.19) — top-tier attenuation for in-ear foam protection
- 200-pair bulk box lowers per-pair cost for daily issue programs
- Soft slow-recovery foam is comfortable for full shifts
- Hi-vis yellow makes compliance checks fast on the floor
- Uncorded design removes cord snag hazard for clean-handed work
Cons
- Single-use — not washable or reusable
- Uncorded plugs are easy to set down and lose; no cord to keep them with the wearer
- Real-world attenuation is well below the 33 label (OSHA ~13 dB, NIOSH ~25 dB) and fit-dependent
- Must be rolled down and inserted with clean hands, which limits use in dirty trades
How It Compares
Within 3M's E-A-R foam line, the E-A-Rsoft Yellow Neons 312-1250 shares its NRR 33 rating with the classic E-A-R Classic 310-1101; the Neons use a softer, slow-recovery foam and hi-vis color, while the Classic is the firmer original. Step down to the 3M 1110 (NRR 29) corded foam plug if you need a cord to keep plugs with the wearer in dirtier areas, accepting a lower rating. For a washable alternative, the 3M E-A-R UltraFit (NRR 27) reusable flanged plug trades some attenuation for reuse. If you want a non-insert option for high in/out frequency, compare with banded semi-aural protectors in our hearing protection range and the ear plugs vs ear muffs guide. The 312-1250's edge is simple: the highest foam NRR in a low-cost, single-use, uncorded format sold by the 200-pair box.

Frequently Asked Questions
What is the NRR of the 3M E-A-Rsoft 312-1250?
NRR 33 (ANSI S3.19), the rating printed on the box. That is a laboratory figure — apply OSHA's (NRR−7)/2 derate (~13 dB) or NIOSH's 25% foam derate (~25 dB) when estimating real-world protection. See our what is NRR guide.
Are these corded or uncorded?
Uncorded. The Yellow Neons 312-1250 listed here have no connecting cord, which removes a snag hazard for clean-handed work but means there is no cord to keep plugs with the wearer.
How many pairs come in the box?
200 pairs per box — a bulk pack sized for issuing a fresh single-use pair each shift across a crew.
Are the 312-1250 reusable or single-use?
Single-use. These are disposable foam plugs and should be replaced, not washed. If you need washable plugs, see our reusable ear plugs collection.
Will NRR 33 be enough for my noise level?
Compare your measured dBA against the derated number, not the 33. OSHA (NRR−7)/2 gives about 13 dB and NIOSH's 25% derate about 25 dB. Use how to calculate the NRR you need to check against the 85 dBA action level and 90 dBA PEL.
What does OSHA 1910.95 require?
OSHA 1910.95 sets an 85 dBA action level (triggering a hearing conservation program) and a 90 dBA PEL over an 8-hour TWA. Hearing protectors are selected so the derated attenuation brings exposure below those limits. Details in our OSHA 1910.95 guide.
How do I insert these correctly?
Roll the foam down tight, pull the ear up and back, insert deeply, and hold while it expands. A poor fit loses most of the rated attenuation. Step-by-step: how to insert foam earplugs.
How do these compare to the 3M Classic 310-1101?
Both are NRR 33. The Yellow Neons use softer slow-recovery foam and hi-vis color; the Classic 310-1101 is the firmer original foam. Choose by comfort preference — the attenuation rating is the same.
Why pick uncorded over a corded foam plug?
Uncorded suits clean assembly and packaging where a cord is a snag risk. If hands get dirty or plugs come in and out often, a corded foam plug keeps them with the wearer — browse corded ear plugs.
Are these good for daily issue to a crew?
Yes — that is the intended use. The 200-pair box lowers per-pair cost, the hi-vis yellow speeds compliance checks, and a fresh single-use pair each shift keeps hygiene high.
Can I get a higher NRR than 33?
33 is effectively the ceiling for in-ear foam plugs under ANSI S3.19. To go higher, combine plugs with ear muffs (dual protection), which adds about 5 dB over the better device — not the two ratings summed. See highest-NRR ear plugs.
Where do these fit in my hearing program?
They serve as the high-attenuation foam option for general high-noise areas where uncorded single-use plugs are practical. For program-wide selection across plugs and muffs, start at our hearing protection collection.

Amazing noise cancellation, great comfort, excellent price
I went to an indoor range and bought a pair of ear plugs to complement the over the ear hearing protection. It was still very very loud but manageable. The plug's were sold at $.50 a pair and I figured I could do much better than that. I like to use them at work as I work in an open office that I have trouble concentrating.I brought them to work and it completely removed all ambient noise and conversation. It is a dream. I then brought them to the range and again complemented with an over the ear model and barely heard the shots. It was really stunning. These are the highest NRR rating you can find. I think if you are looking, this is a great way to go. Inexpensive and well worth it.

Perfect sound reduction for sleep
Exactly what I need for a deep sleep. I fall asleep fast, but I end up waking up to every little sound that I hear in the house. I put one in one ear and sleep on the other and it works perfectly. I can still hear what I need to in the house (teenagers coming home), but get the quiet I need to sleep. Very comfortable and easy to get it in the ear.

Great ear plugs. 3M quality!
Love these. Can sometimes be uncomfortable to wear for long periods. Just make sure your ear canals are clean and it wont be an issue. Blocks noise very well.

Great product but terrible packaging and delivery
Package arrive cracked and open on some box seems. There was no proper packaging. Some ear plugs were falling out. Not sure if or how many were lost.

For Small & Big Ears
These fit both small and big ear canals. Most earplugs are too big for my small ear canals, but these fit perfectly. These cancel out conversational tones but not people yelling.
