Published July 16, 2026 · Last updated July 27, 2026

Editorial assessment by Steven Eaton, WC Safety editor, based on published GREEN specifications and category fit. We did not laboratory-test this product.

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 .

Where It Earns Its Slot

Where it earns its slot: Editorial assessment by Steven Eaton, WC Safety editor, based on published GREEN specifications and category fit. We did not laboratory-test this product.. The rest of this review holds the listing to exactly that brief — limits, alternatives, and the ranked guides included.

Honest Limits

Its limits are the category's: protection exists only while the seal does, and label ratings are laboratory numbers. Plan the NRR 22 label at roughly 7.5 dB of field reduction under OSHA's subtract-7-and-halve estimate, and let your measured exposure — not the box — decide whether it is enough. Inspect and maintain per the maker's guidance; a degraded protector fails silently.

Common questions

Is dual protection ever required?

When the derated exposure still clears 85 dBA: doubling up typically adds roughly 5 dB over the higher-rated device, which is how the loudest industrial work is actually covered. Measure first — dual protection is a numbers decision, not a comfort one.

How much of the NRR 22 label reaches the ear?

Plan on roughly 7.5 dB: OSHA's enforcement estimate subtracts 7 dB from the NRR 22 label and halves the remainder. Compare that figure against your measured 8-hour average — and where the result still exceeds 85 dBA, dual protection (plugs under muffs) takes over, not a higher label.

What should earmuff inspection focus on?

The cushions and the clamp: hardened or cracked cushions stop sealing, aging headbands lose clamp force, and glasses temples cost a few dB by breaking the seal line. Replace cushion kits on schedule and treat a slack band as retirement, not character.

Why trust WC Safety

WC Safety is an independent, affiliate-supported review site. It is not a retailer: it holds no inventory, takes no orders, and earns only from qualifying purchases through clearly marked links — which never changes what a product is rated to do. Standards language is taken from the regulation text directly, and ratings are reported as the manufacturer publishes them. We run no laboratory and perform no testing of our own. Where published sources disagree, we say so and plan on the conservative figure rather than the flattering one.

Our methodology

Figures come from the regulation and the published specification, in that order. Derated numbers are calculated, not estimated. Nothing here is presented as a measured result, because we measure nothing.
