3M Folding Ear Muffs, NRR 25 dB Passive Over-the-Head Hearing Protection, Adjustable Padded Headband Overview
The 3M Folding Ear Muff is a passive, over-the-head hearing protector rated NRR 25 dB (ANSI S3.19). It is built for buyers who need dependable, no-frills attenuation that folds flat into a tool bag, glove box, or range bag. The padded headband and adjustable cups let one pair fit a range of head sizes across a shift.
Because this is a passive muff, there is no electronics, no battery, no Bluetooth, and no sound amplification or impulse compression — it blocks noise mechanically up to its NRR. If you want amplified situational awareness, see our electronic ear muffs instead. For sustained exposure, this muff is best for hearing protection in moderate-to-loud environments.
The labeled NRR is a laboratory figure. Real-world protection is almost always lower than the printed number because of fit, hair, glasses, and seal break. NIOSH recommends derating muffs (commonly by 25%), so plan on roughly 18–19 dB of effective attenuation from a 25 dB muff, then verify against your measured noise level. Our guide on how to calculate the NRR you need walks through the math, and what is NRR explains the rating system.
Employers must meet OSHA 1910.95: when an 8-hour time-weighted average reaches or exceeds 85 dBA, hearing protectors and a conservation program are required. Confirm this muff's derated attenuation drops your exposure below that threshold. Deciding between cups and plugs?

What It Is Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| General construction / job-site noise | Strong | NRR 25 dB passive muff covers many trades; derate to ~18-19 dB and verify against your measured dBA per OSHA 1910.95. |
| Mowing, trimming, grounds-keeping | Strong | Folds flat for storage between jobs; padded headband suits multi-hour wear in moderate-to-loud yard equipment noise. |
| Indoor or outdoor gun range | Good | Passive 25 dB blocks steady noise but offers no amplification for range commands; double up with plugs for high-caliber impulse noise. |
| Situational-awareness work (need to hear speech/alarms) | Limited | This is passive — no microphones or sound restoration. Choose electronic ear muffs if you must hear voices between loud bursts. |
| Very high steady noise (95 dBA+ TWA) | Limited | A derated 25 dB muff may not be enough alone; consider a higher-NRR muff or dual protection (muff + plug). |
| Cap-mounted use with a hard hat | Not suitable | This is an over-the-head headband model, not a cap-mount muff; pick a slotted cap-mount muff for hard-hat integration. |
Earmuffs reduce noise, but the labeled NRR is a laboratory number — real-world protection is lower (NIOSH and OSHA both derate it). The muff only protects if the cushions seal fully around the ear: long hair, eyeglass temples, and gaps under a hard-hat-mounted muff all break the seal. In very high noise, wear muffs and earplugs together (dual protection). Electronic muffs amplify quiet sounds and cut loud impulses but still protect only to their rated NRR. OSHA 29 CFR 1910.95 sets the 85 dBA action level; size protection to your measured noise — see how to calculate the NRR you need.
Pros & Cons
- Passive design — no batteries, charging, or electronics to fail on the job
- NRR 25 dB (ANSI S3.19) covers a wide range of construction and yard-equipment noise
- Folding headband collapses flat for storage in a tool bag or range bag
- Padded, adjustable headband supports multi-hour wear and varied head sizes
- Over-the-head fit works without a hard hat and is fast to don and doff
- No amplification or sound restoration — you cannot hear speech or alarms better than with plain muffs
- No Bluetooth, AM/FM, or aux audio
- Real-world attenuation is lower than the 25 dB label once derated for fit
- Headband-only — not a cap-mount muff for hard-hat slots
- May be insufficient alone for very high steady-noise environments without dual protection
How It Compares
Within 3M's passive over-the-head lineup, NRR and bulk are the main trade-offs. This folding NRR 25 dB muff sits in the mid-protection range and adds the convenience of a fold-flat headband. If you need higher attenuation in a non-folding headband, a 3M PELTOR Optime 105-class muff steps up to roughly NRR 30 dB but is bulkier. For lighter, lower-profile coverage, an Optime 101-class muff (around NRR 27 dB) trades a little attenuation for reduced weight.
All of these are passive muffs — none amplify quiet sound or compress impulses. If situational awareness is the priority, an electronic muff such as the Howard Leight Impact Sport electronic ear muffs amplifies low-level sound and cuts loud spikes, while still only protecting to its own NRR. Compare every option in our best passive ear muffs guide before you buy.

Frequently Asked Questions
What is the NRR of the 3M folding ear muff?
It is labeled NRR 25 dB under ANSI S3.19. That is a laboratory rating — expect lower effective protection in real use once you derate for fit, hair, and glasses.
How much real-world protection does NRR 25 dB actually give?
Less than 25 dB. NIOSH recommends derating muffs (often by 25%), so plan on roughly 18-19 dB of effective attenuation. Use our guide on how to calculate the NRR you need to match it to your measured noise level.
Is this an electronic or passive ear muff?
It is fully passive. There are no microphones, no amplification, no impulse compression, and no Bluetooth or radio. It blocks noise mechanically up to its NRR. If you need to hear speech between loud bursts, choose electronic ear muffs instead.
Can I hear voices or range commands while wearing these?
Only as well as any plain muff allows — they muffle everything, including speech. They do not amplify quiet sound. For situational awareness, look at an electronic model such as the Howard Leight Impact Sport electronic ear muffs.
Does the headband really fold flat?
Yes. The folding over-the-head headband collapses for compact storage in a tool bag, glove box, or range bag, which is the main reason buyers choose this model over a fixed-headband muff.
Can I mount these on a hard hat?
No. This is an over-the-head headband muff, not a cap-mount model, so it does not fit hard-hat accessory slots. You would need a slotted cap-mount muff for hard-hat use.
Are these good for shooting at the range?
They work for steady range noise as a passive 25 dB muff, but offer no amplification for hearing commands. For high-caliber impulse noise, many shooters double up with ear plugs under the muffs. See our best passive ear muffs guide for options.
Will NRR 25 dB meet OSHA requirements?
It depends on your noise level. OSHA 1910.95 requires protection that brings your 8-hour time-weighted average below 85 dBA. Measure your exposure, apply the derated attenuation, and confirm the result. Read our OSHA 1910.95 overview for the rule.
Should I choose ear muffs or ear plugs?
Muffs are faster to don and doff and easier to fit consistently; plugs give higher attenuation and are cooler in heat. Our ear plugs vs ear muffs guide compares both for your environment.
Do these need batteries?
No. As a passive muff there is nothing to charge or replace — no batteries, no electronics. That is a reliability advantage on long shifts and in the field.
Are these dielectric (safe near electrical hazards)?
The product does not list a verified dielectric rating, so we do not claim one. If you need a non-conductive muff for electrical work, choose a model explicitly marked dielectric and confirm its specification.
