Pyramex PM9010 Review: NRR 24 and It Folds Flat

Pyramex PM9010 Low-Profile Folding Earmuff NRR 24 Review (2026)

Published June 19, 2026 · Last updated July 25, 2026

Finding the right earmuff means balancing noise reduction, comfort, packability, and price. The Pyramex PM9010 stakes its claim in the crowded banded earmuff market with a slim, fold-away design and a solid NRR 24 dB rating — enough protection for most industrial and outdoor work environments where OSHA's hearing conservation threshold of 85 dBA (8-hour TWA) is exceeded. At roughly its listed price on Amazon, it is priced squarely in the budget-to-mid tier, making it accessible for individual workers and supervisors purchasing in small quantities alike.

This review is based on verified product specifications, ANSI S3.19-2001 test data as reflected in the published NRR, and OSHA 29 CFR 1910.95 hearing conservation requirements. No claims are fabricated — what you read here is grounded in what the spec sheet actually says. For a broader look at how the PM9010 stacks against other muffs in the category, see our best hearing protection guide and our deep-dive NRR explained guide.

Pyramex Safety has built a reputation for producing affordable, compliance-ready PPE across eyewear, hard hats, and hearing protection. The PM9010 fits that mold: it is ANSI S3.19 tested and listed, ships with a published NRR of 24 dB, and is designed to fold down for pocket or bag storage — a practical differentiator for workers who move between noise zones and quiet areas throughout the day.

Who the Pyramex PM9010 Is For

The PM9010 is purpose-built for workers and enthusiasts who need ANSI-compliant hearing protection that disappears into a pocket or tool bag when not in use. It is a strong fit for:

• Construction and trades workers who alternate between loud power-tool use and quiet conversations throughout the day
• Light manufacturing and assembly environments where noise levels fall in the 85–95 dBA range
• Landscaping and grounds maintenance workers using mowers, blowers, and trimmers
• Range shooters and hunters in non-electronic-hearing-protection settings where passive NRR 24 is sufficient — see our best hearing protection for shooting guide
• Supervisors and safety managers looking for cost-effective compliant muffs to stock for visitor areas
• Workers enrolled in an OSHA-mandated hearing conservation program who need a backup or rotation muff

It is not the right choice for workers in very high-noise environments above 100 dBA (8-hour TWA) who would need higher-NRR muffs or a dual-protection earplug-plus-muff combination. For those settings, consult our best earplugs for work guide to understand when dual protection is required.

PM9010 Strengths in Detail

1. ANSI S3.19-Certified NRR 24 dB Protection

The most critical spec on any hearing protector is the Noise Reduction Rating. The PM9010 carries an NRR of 24 dB, measured and published under ANSI S3.19 test methodology. Under OSHA 29 CFR 1910.95, the de-rated real-world attenuation is calculated as (NRR − 7) ÷ 2 = 8.5 dB when using the standard workplace de-rating formula. That means a worker in an 85 dBA environment would experience an effective exposure of approximately 76.5 dBA — safely below OSHA's 8-hour permissible exposure limit. In environments up to roughly 95 dBA (8-hour TWA), the PM9010 provides adequate protection when properly worn. For environments between 95–100 dBA, engineering controls or higher-NRR devices should be the primary solution.

2. Genuine Fold-Flat Portability

Many "foldable" earmuffs fold in only one axis and remain bulky. The PM9010's padded headband folds away into the ear cups, creating a genuinely compact profile that fits in a cargo pocket, tool belt pouch, or side compartment of a work bag. This is a meaningful practical feature: workers who can easily pocket their hearing protection are more likely to deploy it when entering a noise zone, which directly supports hearing conservation program compliance goals. The fold mechanism also reduces the chance of damage during transport compared to muffs stored loose in a bag.

3. Adjustable Headband for Multi-User Fit

The height-adjustable headband means the PM9010 can be fitted correctly across a broad range of head sizes — an important factor because an improperly fitted muff fails to achieve its rated NRR. ANSI S3.19 lab testing uses a controlled fit; in the field, fit quality is the primary variable that determines real-world attenuation. The adjustable band allows users to set the cup position so the cushions seat fully around the ear canal rather than resting on the pinna. Proper fit is especially critical for workers with larger head circumferences or users who wear glasses — any corrective eyewear frame that breaks the cup seal will reduce effective attenuation. See our full earmuffs collection if you need a model with enhanced temple-clearance cushions.

4. Low-Profile Cup Design Reduces Equipment Interference

The slim ear cup geometry that defines the PM9010's "low-profile" classification reduces the chance of cups snagging on hard hats, face shields, or respirator headbands. Workers in the full PPE stack who layer multiple head-worn protectors regularly deal with interference between equipment. A slimmer cup reduces that interference footprint. It also contributes to the reduced bulk that makes the fold-flat form factor actually useful rather than merely marketing language.

5. Competitive Value at the ~its listed price Price Point

At an Amazon price of approximately its listed price, the PM9010 competes directly with 3M Peltor and Howard Leight entry-level muffs. The combination of ANSI S3.19 compliance, NRR 24, and fold-flat design at this price point represents strong value. For a safety manager budgeting hearing protection for a 10-person crew, the PM9010 keeps per-unit cost low while delivering genuine compliance documentation. High Amazon ratings (4.8/5 across 23 verified ratings) reinforce confidence that the product as shipped matches expectations. For bulk purchasing guidance, see our best hearing protection guide.

PM9010 Limitations to Know Before Buying

NRR 24 Has a Noise-Level Ceiling

NRR 24 is a solid mid-range rating, but workers in very high-noise environments need to understand its limits. Using the OSHA de-rating formula, effective attenuation is approximately 8.5 dB. In an environment running 105 dBA — common in demolition, heavy equipment operation, or loud stamping/pressing operations — the PM9010 alone brings exposure to roughly 96.5 dBA, still above the 90 dBA PEL for an 8-hour shift. These workers need either a higher-NRR muff or a dual-protection approach (earmuff over earplug). OSHA allows dual protection but it does not simply add the two NRR values — see OSHA 29 CFR 1910.95 Appendix B for the correct calculation. Browse our broader hearing protection collection for higher-NRR options.

No Electronic or Ambient-Sound Pass-Through

The PM9010 is a passive muff. It attenuates all sound uniformly — useful noise (speech, alarms) and harmful noise alike. Workers who need to communicate frequently on the job or who must hear warning signals may find passive muffs operationally disruptive. Electronic hearing protectors with sound-amplification pass-through address this but typically cost substantially more. Our electronic ear muffs collection lists options at various price points for workers with that need.

Slim Cup Geometry May Not Suit All Ear Sizes

Low-profile cup design is a trade-off: it reduces bulk but also reduces the internal cup cavity. Workers with larger auricles (outer ears) may find the cup presses against the pinna rather than seating around it, which both reduces comfort during extended wear and compromises the acoustic seal — effectively reducing real-world NRR below the labeled value. If you fall in this category, a full-size over-ear muff with a larger internal cavity is a better choice.

Long-Term Durability Data Is Not Published

The PM9010 is a budget-tier product, and the manufacturer does not publish cushion replacement intervals, rated service life, or weight specifications. Earmuff cushions degrade over time — compressed or cracked cushions reduce the acoustic seal and the effective NRR. OSHA recommends inspecting hearing protectors regularly and replacing cushions (or the entire device) when deterioration is evident. Cushion replacement availability for the PM9010 should be confirmed with your supplier before committing to a large fleet deployment.

PM9010 vs. Competing Entry-Level Earmuffs

Competitor specs sourced from respective manufacturer data sheets. Prices are approximate Amazon street prices as of June 2026. The PM9010 is the only model in this comparison group that offers a fold-flat headband.

Compatible Accessories and Complementary Protection

The PM9010 is a standalone passive muff. For dual-protection scenarios (required when noise exceeds the effective protection ceiling of your muff), pair with disposable or reusable earplugs from our ear plugs collection. When worn with hard hats, ensure the muff's headband does not conflict with the hard hat suspension — low-profile cups like those on the PM9010 reduce but do not eliminate this risk. Confirm cushion replacement part availability with your distributor before fleet deployment. For a full PPE kit, explore our complete PPE collection.

OSHA and ANSI S3.19 Standards Context

Two standards govern earmuff selection in U.S. workplaces:

• ANSI S3.19-2001 — The American National Standard defining the laboratory test method for measuring NRR. The PM9010's NRR 24 was derived using this method. The test uses a panel of human subjects in a controlled lab environment; real-world attenuation is consistently lower, which is why OSHA applies a de-rating factor.
• OSHA 29 CFR 1910.95 — The general industry hearing conservation standard. It requires employers to implement a hearing conservation program when workers are exposed to 85 dBA or greater (8-hour TWA), provide hearing protectors at no cost to workers, and ensure the selected protector reduces exposure to at least 90 dBA. The PM9010's NRR 24 meets this requirement in environments up to approximately 95 dBA using OSHA's de-rating formula.

OSHA's de-rating method: Effective attenuation = (NRR − 7) ÷ 2. For the PM9010: (24 − 7) ÷ 2 = 8.5 dB. Apply this reduction to your TWA noise measurement to determine if the PM9010 provides compliant protection for your specific noise exposure. Our NRR guide covers all three NIOSH-recognized de-rating methods in detail.

Frequently Asked Questions — Pyramex PM9010

What is the NRR of the Pyramex PM9010?

The PM9010 has an NRR (Noise Reduction Rating) of 24 dB, tested under ANSI S3.19. Using OSHA's de-rating formula ((NRR−7)÷2), effective real-world attenuation is approximately 8.5 dB.

Is the Pyramex PM9010 OSHA compliant?

Yes — the PM9010 is ANSI S3.19 tested, which is the standard OSHA recognizes for hearing protector NRR ratings under 29 CFR 1910.95. Whether it provides adequate protection depends on your specific noise exposure level. Use the de-rating formula to verify it meets the 90 dBA protection requirement for your site.

Does the PM9010 fold flat?

Yes. The PM9010's padded headband folds into the ear cups for compact storage. This is the model's primary design differentiator — it is purpose-built for workers who need to pocket hearing protection between noise exposures.

What environments is NRR 24 adequate for?

Using OSHA's de-rating formula, NRR 24 provides approximately 8.5 dB of effective attenuation. It is adequate for environments up to approximately 95 dBA (8-hour TWA). For environments above 95 dBA, consider a higher-NRR muff or dual protection. See our NRR guide for a full breakdown.

Can I wear the PM9010 with a hard hat?

The PM9010 is a headband-style muff, not a hard-hat-mounted cap muff. It can be worn simultaneously with a hard hat. The low-profile cup design reduces but does not eliminate the risk of headband interference with the hard hat's suspension system. Test fit with your specific hard hat model before specifying for crew use.

Is the Pyramex PM9010 good for shooting?

For passive (non-electronic) hearing protection at the range, NRR 24 provides meaningful attenuation for pistol and rifle fire. However, many shooters prefer electronic muffs that block impulse noise while allowing normal conversation. See our best hearing protection for shooting guide for a full comparison.

What is the difference between the PM9010 and a standard earmuff?

The PM9010 is distinguished by its fold-flat headband mechanism and slim (low-profile) ear cups. Standard banded muffs typically have a fixed headband that does not fold. In terms of NRR and protection mechanism, the PM9010 functions identically to any other passive banded earmuff.

How do I properly fit the Pyramex PM9010?

Adjust the headband so the ear cups sit centered over the ear canal with the cushions fully contacting the skin around the ear. There should be no visible gaps in the cushion seal. A gap caused by eyeglass temples, hair, or an incorrect headband length reduces the effective NRR below the labeled value.

Can I wear earplugs under the PM9010 for dual protection?

Yes. OSHA permits dual protection (earmuff over earplug) for very high-noise environments. The combined NRR is not the sum of the two NRRs; OSHA's approach adds 5 dB to the higher of the two NRRs. Pair with foam or reusable earplugs from our ear plugs collection.

What is the ASIN for the Pyramex PM9010 on Amazon?

The ASIN is B00KG6WIK8. The UPC is 796793684632.

Does the PM9010 have replaceable cushions?

Pyramex does not publish a replacement cushion part number for the PM9010 in the standard retail channel. Confirm cushion availability with your distributor before fleet-deploying these muffs in a long-term hearing conservation program.

How does NRR differ from SNR?

NRR (Noise Reduction Rating) is the U.S. EPA/OSHA standard measured under ANSI S3.19. SNR (Single Number Rating) is the European equivalent under EN 13819. They are not directly comparable. The PM9010's NRR 24 applies to U.S. regulatory compliance calculations. See our NRR guide for a full explanation.
