ProCase NRR 28 dB Ear Muffs — Over-the-Head Passive Hearing Protection Overview
The ProCase Noise Reduction Ear Muffs are over-the-head, passive hearing protectors carrying a published Noise Reduction Rating (NRR) of 28 dB measured under ANSI S3.19. The adjustable headband and padded ear cups make them a general-purpose pick for mowing, leaf blowing, shop and power-tool work, and recreational range days where you need consistent, no-battery coverage. As a passive muff there is nothing to charge and nothing to fail — you put them on and the seal does the work.
Be realistic about what NRR means. The NRR 28 dB figure is a laboratory number; field attenuation is almost always lower because of fit, glasses-temple gaps, and how the seal sits over your ears. NIOSH recommends derating the label, and OSHA uses a similar correction when evaluating workplace exposure — a common rule of thumb is to subtract 7 from the NRR, then halve the remainder, to estimate real-world dB(A) reduction. If you work at or above an 8-hour 85 dBA time-weighted average under OSHA 1910.95, derate first and verify the result puts you under 85 dBA. New to the math? Start with what is NRR and our how to calculate NRR walkthrough.
These are designed to sit over the head — they are not a cap-mount muff for hard-hat slots, and they are not a behind-the-neck/folding low-profile design. They are also not dielectric-rated, so they should not be relied on as electrical protection around live conductors. If you want amplification or media, that is a different category — see our electronic ear muffs. For the full passive lineup, browse ear muffs or the broader hearing protection range.

What It Is Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| Lawn / yard power tools (mower, blower, trimmer) | Strong fit | NRR 28 over-the-head coverage handles typical 90-100 dB yard equipment; derate and confirm you land under 85 dBA. |
| Workshop & power tools (router, saw, grinder) | Strong fit | Passive seal with no batteries to die mid-task; pair with plugs for the loudest impulse tools. |
| Recreational / outdoor range | Good fit (passive) | Solid passive protection, but with no electronics you will not hear range commands between shots — many shooters prefer electronic muffs there. |
| Hard-hat / climbing work | Not suited | This is an over-the-head muff, not a cap-mount model; choose a cap-mount earmuff that clips into helmet slots. |
| Electrical / live-conductor work | Not suited | Not dielectric-rated; select an electrically insulated cap-mount muff for that hazard. |
| Concerts, sleep, sensory comfort | Check exposure first | Consumer comfort use is outside our spec focus; for occupational noise, size the NRR to the measured dB level rather than a 'soundproof' claim. |
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
Pros
- Published NRR 28 dB under ANSI S3.19 — strong passive coverage for common 90-100 dB tasks
- Over-the-head form factor with an adjustable headband for a range of head sizes
- Passive design: no batteries, charging, or electronics to fail
- Padded ear cups for extended-wear comfort during yard and shop work
- Amazon-fulfilled with current pricing and live buyer ratings
Cons
- Real-world attenuation is lower than the NRR 28 label — derate before relying on it for OSHA compliance
- Passive only: does not amplify quiet sounds, so you can't hear range commands or conversation through them
- Not a cap-mount muff — won't attach to hard-hat slots
- Not dielectric-rated; not for electrical/live-conductor protection
- Listing markets 'soundproof' and sensory uses — no muff blocks all noise; size to measured dB instead
How It Compares
Within passive, over-the-head muffs, the ProCase at NRR 28 dB sits in the upper-middle of the range. For reference among siblings WC Safety carries: the Moldex MX-6 over-the-head earmuffs are also a battery-free passive muff in a similar use class, while the Radians Def-Guard 23 earmuff carries a lower NRR 23 dB for lighter-noise tasks. If you need to hear while protected — range commands, conversation, or media — a passive muff can't do that; step over to electronic models such as the Howard Leight Impact Sport electronic ear muffs, which amplify quiet sound and compress loud impulses but still only protect to their own NRR. Choose by the noise level you actually measure: see best passive ear muffs to compare the passive field, and ear plugs vs ear muffs if you're weighing a dual-protection setup for the loudest environments.

Frequently Asked Questions
What is the NRR of the ProCase ear muffs?
They carry a published Noise Reduction Rating of 28 dB, measured under ANSI S3.19. Treat that as the lab label and derate it for real-world use.
Is NRR 28 dB enough for my noise level?
Often yes for common 90-100 dB tasks, but you must derate first. A common rule subtracts 7 from the NRR and halves the remainder — about 10-11 dB of real protection here. Confirm that drops your exposure below 85 dBA using our how to calculate NRR guide.
Are these electronic ear muffs with Bluetooth or a radio?
No. We treat and rate the ProCase as a passive over-the-head muff — there's no verified amplification, Bluetooth, or AM/FM radio. If you need to hear quiet sound or media while protected, browse our electronic ear muffs instead.
What form factor are these?
Over-the-head with an adjustable headband. They are not a cap-mount muff for hard-hat slots and not a folding or behind-the-neck low-profile design.
Can I attach these to a hard hat?
No. These mount over the head, not into a helmet's accessory slots. For hard-hat use, choose a cap-mount earmuff designed to clip into those slots.
Are the ProCase muffs dielectric-rated for electrical work?
No. They are not dielectric-rated and should not be used as electrical protection around live conductors. Select an electrically insulated cap-mount muff for that hazard.
Do these meet OSHA hearing protection requirements?
Hearing protectors support compliance, but the muff alone doesn't make you compliant. Under OSHA 29 CFR 1910.95, derate the NRR and verify your 8-hour TWA falls below 85 dBA. See our OSHA 1910.95 overview for the full requirement.
Will these block out all noise / are they soundproof?
No muff is soundproof. NRR 28 reduces noise; it doesn't eliminate it, and real-world reduction is lower than the label. Size your protection to the measured dB level rather than a 'block everything' claim.
Are these good for shooting at the range?
They give solid passive protection, but with no electronics you won't hear range commands or conversation between shots. Many shooters prefer electronic muffs there — compare options in our best electronic ear muffs guide.
Should I pair these with ear plugs?
For the loudest impulse environments, yes — dual protection (plugs plus muffs) adds roughly 5 dB over the better device alone, not the sum of both. Read ear plugs vs ear muffs to decide.
How do these compare to other passive muffs you carry?
At NRR 28 dB they sit in the upper-middle range. The Radians Def-Guard 23 earmuff is lower at NRR 23 dB for lighter noise, while the Moldex MX-6 over-the-head earmuffs are a similar battery-free passive option. Our best passive ear muffs guide lines them up.

Comfortable and Effective Hearing Protection
I purchased these earmuffs for use around loud equipment and other noisy environments, and they have worked very well. They noticeably reduce noise while still being comfortable enough to wear for extended periods.The padding is soft, the headband adjusts easily, and they feel sturdy without being overly heavy. They also fold up nicely for storage when not in use.For the price, the quality exceeded my expectations. They provide reliable hearing protection and have been a useful item to keep on hand.

They work...
Bought these for outdoor lawn work and they do muffle the noise quite well. A little tight on my large head but still comfortable after hours of wearing. Great deal for the dollar's spent.

A nice reliable pair of ear defenders for autism
Appearance: The color pink is accurate to the picture shown.Size: Fits my adult head well, has expanders to fit height to size. I don’t feel like my head is being crushed as others have said, though I don’t have a wide head. Appearance wise, they look bigger than the ear defenders I typically see people wearing but I don’t mind.Ease of Use: They are very easy to fit back into a ball to carry. It takes a bit of pulling to get them to fit on the head because you have to expand the metal out of the cuffs. I was a bit surprised by the force needed but once I did it a few times it became easier.Feel: I can have these on my head all day long. The cuffs fit completely over my ears so they are extremely comfortable in that way. It does put pressure inside my ears as if I was on an airplane. It’s not majorly bothersome but takes a bit of getting used to.Sound: When I first put these over my ears, I actually started tearing up because everything got so quiet. All of the background noise just completely stopped. I can still hear people talking. I can hear sirens. I can hear overhead announcements. But it blocks out a lot of the music sounds that hurt as well as the general small repetitive noises that would make me angry like chewing or walking or people tapping, etc.Durability: I cannot say anything on this quite yet as I’ve only had them a few days, but so far they have been durable. I have taken them on a trip and they held up well with me tossing them around and dropping them. The cushion on the part that sits on my head is still in tact. The metal feels sturdy. The cushions on the ear muffs do not have any imperfections. And the pink part is a very hard plastic.Sleep quality: I actually have fallen asleep with these on and I didn’t wake up in pain at all. I was very comfortable the whole time. They are a bit bulky to get used to and lay on but once you figure out a good position, it feels nice.Overall I would recommend. This is my first pair of ear defenders so I have nothing to compare it to, but I really like these.Update 4 months later: I’m glad this review has been helpful so I’m adding this addition. I absolutely love these and am glad I picked this pair. I am now used to wearing them the majority of the day. The pressure in the ears is gone, the toughness of pulling the defenders to my size is gone and is now a smooth process. They are durable, pads are still cushiony with regular, frequent use. No scratches or scuffs. The pad on the headband is still sturdy and cushiony. They feel like an extension to me now that I’ve gotten used to them. Definitely recommend this brand.

They Do there job but are small and uncomfortable
They cut the noise out very well. Downside is they are small, tight and uncomfortable. Probably good for youth but would not recommend for an adult.

Do not adjust very much
The noise reduction seems goodBUTThe adjustment range is small. The ear cups seem small also. For occasional use, they are ok, but for more than a half hour, they are painful to wear. I would only recommend for occasional use based on price. Everyday, longterm use, find something else. That's what I'm doing now.
