VeriShield VS120FHV Review: NRR 27 Hi-Viz Folding Earmuff

What is the NRR of the Howard Leight VeriShield VS120FHV?

The VS120FHV has an NRR (Noise Reduction Rating) of 27 dB as measured under ANSI S3.19 laboratory test protocols.

What does NRR 27 protect against in real-world conditions?

Using OSHA's recommended earmuff derating formula — (NRR minus 7) divided by 2 — the VS120FHV provides approximately 10 dB of real-world noise reduction. This is sufficient for workers with TWA exposures up to approximately 100 dB to maintain exposure at or below the 90 dB OSHA PEL. See our NRR guide for full calculation methodology.

Why is the VS120FHV hi-viz yellow?

The high-visibility yellow cup color allows supervisors and safety officers to confirm PPE compliance at a distance without requiring close inspection. This is especially useful in facilities with formal hearing conservation programs that document PPE use under OSHA 29 CFR 1910.95.

What is the difference between the VS120FHV and the standard VS120?

The only difference is the cup color. The VS120FHV is hi-viz yellow; the VS120 is standard. Both have identical NRR 27 ratings, memory-foam cushions, steel-wire headbands, and folding designs. Choose the FHV for compliance-monitoring environments; choose the VS120 where color is not operationally relevant.

Does the VS120FHV fold flat?

Yes. The folding design allows the earcups to rotate inward, substantially reducing storage volume compared to fixed-arm earmuffs. This makes the VS120FHV practical for storage in lockers, toolboxes, vest pockets, or hard hat carriers.

Are the VS120FHV cushions replaceable?

Howard Leight / Honeywell offers replacement cushions for the VeriShield series. Replacing worn cushions restores the acoustic seal and extends the useful life of the earmuff body without requiring full replacement. Check our hearing protection accessories for availability.

What does oil-resistant ABS mean for service life?

ABS (acrylonitrile butadiene styrene) plastic formulated with oil resistance maintains its structural integrity and surface properties when exposed to machine lubricants, cutting fluids, or airborne oil mist — common in manufacturing and automotive environments. Standard ABS can degrade in these conditions; the oil-resistant formulation extends the cup body's service life in such environments.

Can I wear the VS120FHV over a hard hat or bump cap?

The VS120FHV is a standard headband earmuff and is not configured as a helmet-mount model. For hard hat compatibility, you would need hard-hat-mount earmuff caps designed to clip to ABS helmet slots. Browse our ear muffs collection for helmet-compatible configurations.

Is the VS120FHV suitable for shooting ranges?

For shooting range use, NRR 27 provides adequate passive attenuation for sustained rifle and pistol fire at indoor ranges where NRR 25 or higher is typically recommended. However, shooters who need to hear range commands, communicate, or detect ambient sounds between shots often prefer electronic earmuffs with impulse suppression. See our guide on best hearing protection for shooting and our shooting hearing protection collection for alternatives tailored to that application.

What TWA noise level does NRR 27 protect against?

Using OSHA's derating formula for earmuffs: a worker exposed to 100 dB TWA would have an estimated protected exposure of 90 dB — exactly at the OSHA PEL. For exposures above 100 dB TWA, a higher NRR earmuff or dual protection (earmuff plus earplug simultaneously) may be required. Consult your industrial hygienist and reference our NRR guide.

What OSHA regulation governs hearing protection in the workplace?

OSHA's occupational noise exposure standard is 29 CFR 1910.95 (General Industry) and 29 CFR 1926.52 (Construction). These regulations set the PEL at 90 dB TWA for an 8-hour shift and require a hearing conservation program — including audiometric testing, training, and provision of hearing protectors — when exposures reach 85 dB TWA. See our complete hearing conservation program guide for implementation detail.

Does hi-viz hearing protection meet any specific standard?

OSHA 29 CFR 1910.95 does not mandate high-visibility hearing protection colors. However, individual industry standards, contractor specifications, or facility-level safety programs may require hi-viz PPE across all categories. The VS120FHV's yellow color satisfies those facility-level requirements where they exist. Always verify your specific program's requirements.

What NRR 27 delivers on a real head, not a test fixture

The Noise Reduction Rating on the box is a laboratory number, measured on trained subjects with the muff seated perfectly. Nothing about a real shift reproduces that, and the regulator does not assume it does.

OSHA 29 CFR 1910.95 derating. Subtract 7 from the NRR, then halve the result as a safety factor:

So a muff badged 27 is planned around roughly 10 dB. In a 100 dBA area that leaves about 90 dBA at the ear — still above the 85 dBA action level, which is not what the number on the packet suggests.

NIOSH derating is kinder to a muff than to a plug, and that difference matters when you are choosing between the two. NIOSH cuts the NRR by 25% for earmuffs, 50% for formable foam earplugs and 70% for every other earplug type. At NRR 27 that puts this muff near 20.2 dB by the NIOSH route.

The reason a muff keeps more of its label is that it is harder to fit wrong. A plug that is half-inserted looks inserted; a muff that is not sealed is usually obvious to the wearer within a minute. That is the real argument for muffs in a mixed crew — not a higher number, but a smaller gap between the number and the wearer.

Over-the-head, behind-the-neck, or cap-mounted — the trade you are making

All three are the same cup and the same foam. What changes is how the band loads the cushion against your head, and that shows up directly in the rating.

• The pattern is not an accident. A headband over the crown puts the cushion under the most even pressure, so over-the-head models rate highest. Behind-the-neck and cap-mount give some of that up in exchange for compatibility with what else is on your head.
• Spend the rating where the noise is. Eight NRR points separate the VS130 from the VS110N. If the hard hat is non-negotiable, the cap-mount is the honest choice — but plan the exposure on 24, not on 30.
• Anything between the cushion and your head is a leak. Safety-glasses temples, a beanie, a hood, long hair, or a dust mask strap all break the seal. A thin temple arm is worth more here than a few NRR points on the box.
• Cap-mount only fits helmets with the right slots. Check the slot standard on your specific helmet before assuming it will attach.

Fit beats rating, every time

A foam earplug only works if it is rolled down thin, inserted deep enough, and held while it expands. A plug resting in the outer ear can deliver a small fraction of its rating — the difference between a good and a poor insertion is far larger than the difference between an NRR 27 plug and an NRR 33 one.

• Roll the whole plug into a thin crease-free cylinder, do not just pinch the tip.
• Pull the ear up and back with the opposite hand to straighten the canal before inserting.
• Hold for the full expansion time — releasing early is the commonest error, and the plug backs out as it expands.
• Check it. With plugs seated correctly, your own voice sounds hollow and muffled. If it sounds normal, they are not in.

Where a program needs evidence rather than technique, fit testing for hearing protection exists and produces a measured personal attenuation rating for the individual — the hearing equivalent of a respirator fit test, and far more informative than any label.

Related hearing protection

Foam and reusable plugs sit under corded ear plugs, within the wider hearing protection range. Where plugs cannot be worn — ear infections, frequent on-off cycles, or a workforce that will not insert them consistently — ear muffs are the more reliable choice because their fit is far less technique-dependent. For intermittent noise where hearing speech between exposures matters, see banded ear plugs.

What using one of these legally requires

An earplug is not a compliance strategy on its own. Where noise exposure reaches the action level, OSHA 29 CFR 1910.95 requires a hearing conservation program, and the protector is one part of it:

• The action level is an 8-hour TWA of 85 dBA. At or above it the employer must run the program. The permissible exposure limit is 90 dBA as an 8-hour TWA, on a 5 dB exchange rate — so 95 dBA is a 4-hour exposure and 100 dBA a two-hour one. NIOSH recommends a lower 85 dBA limit on a 3 dB exchange.
• Monitoring comes first. A noise survey establishes who is exposed and to what. Choosing a protector by its rating without knowing the level it has to bring down is guesswork in both directions.
• Audiometric testing. A baseline audiogram within six months of first exposure, then annually. That test — not the number on the packet — is the evidence that the program is working.
• Protectors provided at no cost, with a real choice. Employees must be able to select from a variety of suitable protectors, and be trained in fitting, care and use. Attenuation has to be adequate for the actual exposure.
• Training annually, and records kept. Exposure measurements and audiometric records are retained; training is repeated every year.

Two limits apply regardless of the model. Hearing protection sits at the bottom of the hierarchy of controls — where feasible engineering or administrative controls can bring exposure down, they are required, and a plug is not a substitute for them. And a rating is a laboratory ceiling reached only with a correct fit, which is why fit and training move the outcome more than a higher number on the box.

Why trust WC Safety

WC Safety is an independent, affiliate-supported review site. We hold no inventory, sell nothing directly, and earn only from qualifying purchases made through clearly marked links — which never changes what a hearing protector is rated to do. This review is compiled by Steven Eaton from the manufacturer’s published listing, the EPA-labeled Noise Reduction Rating that appears on the packaging, and the text of OSHA 29 CFR 1910.95 and the NIOSH hearing-loss prevention criteria. We hold no laboratory, run no attenuation testing, and publish no customer-rating aggregate, because we have no customers to aggregate. Where the published record disagrees with itself, we say so rather than pick a figure.

Our methodology

Specifications come from the live listing and its variant record; standards language comes from OSHA 29 CFR 1910.95 and the NIOSH criteria directly. The NRR is reported as the manufacturer publishes it and then derated by a stated method — OSHA’s (NRR − 7) ÷ 2, or the NIOSH percentage for the device type — never presented as the protection a wearer receives. The score is an editorial judgment of specification, fit type and value: not a measured result, not an attenuation test, and not an average of user ratings.
