The Howard Leight Multi Max MM-1 Cordless Earplugs — NRR 31 is a disposable cordless ear plugs from Howard Leight, listed on Amazon. This review restates what the product page documents, places it in its hearing protection lane, and points to the ranked guides for the head-to-head field.
What the Product Page Documents
Published · Last updated
Best For: corded single-use foam hearing protection at NRR 31 dB in a low-profile uncorded design.
Not For: non-noise hazards, or noise that earplugs alone can't bring under ~85 dBA (add earmuffs).
Bottom Line: a practical single-use foam plug at NRR 31 dB — the uncorded low-profile fit suits tight spaces and high-volume single-use.
Where It Earns Its Slot
The MM-1 is the high-rating end of Howard Leight's uncorded foam: NRR 31 in a low-profile shape that sits nearly flush with the ear — the combination that earns it a 4.9/5 here. Flush profile matters more than it sounds: plugs that protrude get knocked loose by hoods, helmets, and shoulder checks, and a knocked plug is an unprotected ear.
Its family alternatives split by format: the Multi Max R-03318 serves crews by the 200-pair box at the top of the family's label range, while the corded foam line — FF-30 and LT-30 — covers jobs where retention beats profile. The MM-1 is the pick for tight-quarters work where both a cord and a protruding plug are liabilities.
Honest Limits
NRR 31 plans at roughly 12 dB after OSHA's subtract-7-and-halve derating — near the top of what single foam plugs deliver, and still not a substitute for muffs-over-plugs where the derated average clears 85 dBA. The low-profile shape also hides poor seating from a visual check: verify fit by occlusion (the wearer's own voice booms when the seal is right), not by looking.

The Bottom Line
Rated 4.9/5. The MM-1 pairs one of the family's highest foam ratings with the shape least likely to get knocked out, which makes it the uncorded pick for confined, helmeted, high-movement work. Crews buy the R-03318 box; cord-required sites go back to the FF-30 lane.

How We Review
Hearing reviews restate the NRR exactly as each listing states it — the EPA-labeled rating, not marketing decibels. Fit discipline (full-depth foam insertion, sealed muff cushions) is the difference between rated and real attenuation, and the reviews say so. Ratings reflect documented spec, configuration, and value — the basis is stated, not invented testing.

Common questions
What does the Howard Leight Multi Max MM-1 Cordless Earplugs — NRR 31 listing actually document?
Best For: corded single-use foam hearing protection at NRR 31 dB in a low-profile uncorded design.…
What are the alternatives to the Howard Leight Multi Max MM-1 Cordless Earplugs — NRR 31?
The sibling disposable cordless ear plugs options linked in this review, ranked head-to-head in the hearing protection guides below — start with the buyer's guides for the field view.
Why does a low-profile plug matter?
Because protruding plugs get bumped — by hood edges, helmet straps, and contact — and every bump breaks the seal. A plug that sits flush survives real movement, which is why the MM-1's shape is a protection feature, not a comfort one.
How do I check the fit of a nearly flush plug?
By sound, not sight: with a proper seal the wearer's own voice sounds boomy and muffled (the occlusion effect), and ambient noise drops noticeably. If speech sounds normal to the wearer, the plug is not sealed regardless of how it looks.
What field number should planning use for NRR 31?
Roughly 12 dB under OSHA's enforcement derating. That covers most loud industrial work as a single protector — and where measurements still exceed 85 dBA after derating, the MM-1 becomes the under-muff layer of dual protection.
MM-1 or the R-03318 box?
Same Multi Max family, different formats: the MM-1 serves individual and small-quantity buyers, the R-03318 stocks dispensers by the 200-pair box. For a crew standardizing on Multi Max, the box is the economical route.

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.
