GREEN DEVIL Behind-the-Head Ear Muffs - NRR 22 Low-Profile Neckband Hearing Protection Overview
The GREEN DEVIL Behind-the-Head Ear Muffs are passive, low-profile neckband hearing protectors rated NRR 22 (ANSI S3.19) and SNR 27 (EN 352). Instead of an over-the-head crown band, the headband wraps behind the head / behind the neck, so the cups seat without competing for crown space. That makes this muff a practical pick when a standard headband collides with a hard hat, welding shield, brimmed cap, or face screen.
Note on the rating: the NRR 22 figure is a laboratory number. Per NIOSH and OSHA, real-world attenuation is lower once you apply a derate, so treat 22 dB as a ceiling, not a guarantee. Use it to verify the muff brings your protected exposure under the 90 dBA (8-hour TWA) permissible limit and 85 dBA action level set by OSHA 1910.95. If you are unsure how the rating maps to your noise level, see how to calculate the NRR you need and the breakdown of what NRR means.
This is a behind-the-head ear muff built for compatibility, not maximum dB. If you need a higher number, compare against over-the-head muffs in our hearing protection range or read our passive ear muff guide. For dual protection in very loud environments, pair the band with foam plugs and review ear plugs vs ear muffs.
What It Is Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| Hard hat / safety helmet use | Strong fit | The behind-the-head band clears the crown, so cups seat without fighting the hard-hat shell or suspension. |
| Welding & grinding with a shield | Strong fit | Neckband routing leaves the crown free for a welding helmet or flip-up face shield at NRR 22. |
| Brimmed-cap and face-screen jobs | Strong fit | Low-profile band sits below a ball cap or forestry screen where over-the-head muffs ride up. |
| General construction & grounds work | Good fit | NRR 22 covers moderate continuous noise; verify against your measured TWA under OSHA 1910.95. |
| Extreme impulse noise (heavy firearms, jet ops) | Limited fit | NRR 22 is on the lower end; choose a higher-rated muff or double up with plugs for those exposures. |
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
- Behind-the-head / behind-the-neck band clears hard hats, welding shields, and brimmed caps that block over-the-head muffs
- Low-profile neckband design keeps the crown free for other head gear
- NRR 22 (SNR 27) passive attenuation suited to moderate continuous noise
- Simple passive cups - no batteries to charge or replace
- Lightweight neckband form factor for extended wear under a helmet
Cons
- NRR 22 is lower than top over-the-head muffs; real-world protection is lower still after the OSHA/NIOSH derate
- Behind-the-head bands can shift if you bend or look down frequently
- Not a fit when you need maximum dB reduction for very loud impulse noise
- No published weight or dielectric rating to confirm for electrical work
How It Compares
Within behind-the-head and low-profile muffs, the GREEN DEVIL trades peak attenuation for headgear compatibility. Its NRR 22 is mid-pack: enough for moderate continuous noise, but below the NRR 25-30 you get from a bulkier over-the-head muff. Choose this band when a crown headband simply will not fit under your hard hat or welding shield; choose a higher-NRR over-the-head muff when raw dB reduction matters more than clearance.
If you want the same neckband convenience plus electronic sound-restoration, browse our electronic ear muffs and noise-canceling headsets instead. For passive over-the-head alternatives in the same NRR range, see the Radians Def-Guard 23 earmuff, or step up to higher-rated electronic options like the Pro Ears Ultra 33 when you need both protection and amplification.

Frequently Asked Questions
What is the NRR of the GREEN DEVIL behind-the-head ear muffs?
They are rated NRR 22 under ANSI S3.19 (and SNR 27 under the European EN 352 method). Remember the NRR is a lab figure; per NIOSH and OSHA, your real-world protection will be lower once a derate is applied.
Are these over-the-head or behind-the-head muffs?
Behind-the-head. The low-profile band wraps behind the head/neck rather than across the crown, so it does not compete for space with a hard hat, helmet, or cap.
Will these fit under a hard hat or welding helmet?
Yes - that is the main reason to buy a behind-the-head muff. Because the band sits below the crown, it leaves the top of your head free for a hard hat, welding shield, or face screen.
Are these cap-mount earmuffs for a hard-hat slot?
No. These are a standalone neckband muff, not cap-mount cups that clip into a hard-hat accessory slot. They work alongside a hard hat rather than attaching to it.
Is NRR 22 enough for my job?
It depends on your measured noise level. Use your noise survey (TWA) and apply the OSHA derate to the NRR; see our guide on how to calculate the NRR you need to confirm it brings you under the 90 dBA limit.
Are these passive or electronic ear muffs?
These are passive muffs - the cups block sound mechanically with no batteries. If you specifically want amplification or Bluetooth, browse our electronic ear muffs collection instead.
Do they meet OSHA hearing-protection requirements?
An NRR 22 muff can satisfy OSHA 29 CFR 1910.95 as long as the derated attenuation lowers your 8-hour TWA below 90 dBA (action level 85 dBA). The right rating depends on your exposure, not the muff alone.
How much real protection do I actually get?
Less than 22 dB. NIOSH recommends derating muffs by about 25%, and OSHA uses a 50% safety factor for compliance, so plan for meaningfully lower attenuation than the printed NRR.
Can I wear these with safety glasses?
Yes. As with any muff, glasses or shield arms passing under the cushion can break the seal slightly; choose thin temples and check the seal to preserve attenuation.
Can I double up with ear plugs for louder work?
Yes. Wearing foam plugs under the muffs adds protection (not simply additive - roughly +5 dB over the better device). See ear plugs vs ear muffs for how to combine them correctly.
Are these dielectric / safe for electrical work?
We do not have a published dielectric rating for this model, so we cannot confirm it for live electrical hazards. If you need a verified dielectric muff, look for one explicitly marked for that use rather than assuming.
What's the difference between the SNR 27 and NRR 22 numbers?
They measure the same muff with different standards: NRR 22 is the US ANSI S3.19 rating and SNR 27 is the European EN 352 rating. For US OSHA compliance, use the NRR 22 figure and apply the derate.
