Howard Leight Maximum Max-1 NRR 33 Cordless Ear Plugs

Howard Leight Max-1 Overview

The Howard Leight Max-1 is a single-use polyurethane foam earplug rated NRR 33 — the maximum in-ear rating — in the bell shape that made the Max series the best-selling disposable plug in North American industry. Its contoured body is designed to fit the widest range of ear canals with a consistent seal, which is why it is the default issue plug in many large hearing-conservation programs.

Where the Max-1 Fits in Hearing-Protection Selection

Confirm the exposure first: continuous or intermittent industrial noise at or above the OSHA 85 dBA action level. The Max-1 carries the top NRR of 33, so it suits the loudest in-ear use cases — but more attenuation is not always better, since over-protection can isolate workers from alarms and speech. Use what NRR means and how to derate it to size the rating, and OSHA 29 CFR 1910.95 hearing conservation for the program rules. Weighing foam against washable plugs? See foam vs reusable ear plugs.

Who Should Buy the Howard Leight Max-1?

• Buy it if you want the proven best-selling NRR 33 plug with a universal bell-shaped fit and predictable bulk supply.
• Buy it if you run a large program and want one plug that fits most workers out of the box.
• Choose the Pura-Fit instead if low insertion pressure for all-day comfort is the priority — the Moldex 6800 Pura-Fit.
• Choose a corded plug instead if workers remove plugs often — see corded ear plugs.
• Choose lower NRR instead where awareness matters — the Howard Leight Multi-Max MM-1 (NRR 31) or Max Lite LPF-1 (NRR 30).

What Does the Max-1 Protect Against?

What the Max-1 Does NOT Protect Against

• It is not a substitute for engineering or administrative noise controls where feasible.
• It does not provide situational awareness or communication.
• It is not metal-detectable and not suitable for food, beverage, or pharmaceutical lines.

Important: A foam earplug only delivers its rated NRR when rolled down tightly and inserted deeply enough to expand in the canal. OSHA and NIOSH recommend derating the labeled NRR in the field. Train workers, confirm fit, and verify exposure within a hearing-conservation program — do not rely on the rated number alone.

Best Applications

Manufacturing & heavy industry

The universal fit and NRR 33 make the Max-1 a safe default issue plug across a mixed workforce. Keep it stocked with ear plug dispensers.

Construction & jobsites

High intermittent noise from saws, breakers, and equipment suits a high-NRR foam plug — see the best ear plugs for construction guide and the construction hearing protection collection.

Maximum-protection programs

At NRR 33 the Max-1 is among the highest-NRR ear plugs and a benchmark in our best disposable ear plugs guide.

Pairing & Bulk Supply

For extreme or impulse noise, pair the Max-1 with muffs for dual protection; for high-traffic areas, stock from a wall dispenser so a fresh pair is always within reach.

Max-1 vs Other Howard Leight Foam Earplugs

Max-1 vs Moldex Pura-Fit

The two benchmark NRR 33 disposable foam plugs. The Max-1 is the best-selling universal bell shape; the Moldex Pura-Fit leads on low insertion pressure for all-day comfort. Verdict: read the full head-to-head in Moldex Pura-Fit vs Howard Leight Max-1.

Max-1 vs Laser Lite LL-1

Both are top-tier Howard Leight foam plugs. The Max-1 (NRR 33) is the universal bell shape; the Laser Lite LL-1 (NRR 32) uses a self-fitting tapered, high-visibility body that workers find the easiest to seat. Verdict: choose Max-1 for the absolute maximum rating; choose Laser Lite where fit errors are the bigger risk.

Howard Leight Max-1 Frequently Asked Questions

How much does a box of Max-1 cost?

WC Safety lists the Max-1 at $41.16 per box.

What does "Max-1" mean?

It is Howard Leight's model name for the single (uncorded) version of the Maximum bell-shaped foam plug; the corded version uses a different model number.

Will the Max-1 fit small ear canals?

The bell shape fits most adults, but workers with very small canals may prefer the Howard Leight Max Lite LPF-1 or Moldex 6600 Softies.

Is the Max-1 latex-free?

Yes — it is polyurethane foam and contains no latex.

Can I reuse Max-1 plugs?

No. Foam absorbs wax and grime and loses its seal; treat each pair as single-use.

Is the Max-1 good for shooting?

It attenuates well, but most shooters prefer level-dependent protection that preserves range commands.

How do I insert the Max-1 correctly?

Roll it into a thin crease-free cylinder, pull the ear up and back, insert past the canal opening, and hold 20–30 seconds while it expands.

Is the Max-1 OSHA compliant?

OSHA does not approve individual plugs; the NRR 33 Max-1 can anchor a compliant 29 CFR 1910.95 program when fitted correctly for the exposure.

Do you offer a lower-NRR Howard Leight plug?

Yes — the Multi-Max MM-1 (NRR 31) and Max Lite LPF-1 (NRR 30) trade a little attenuation for more awareness.

How many should I buy for a crew?

Plan one pair per worker per shift; stock a wall dispenser to keep usage consistent.

Does the Max-1 come metal-detectable?

No — for detectable PPE on food or pharma lines, use the Moldex 6615 SparkPlugs or Howard Leight Laser Trak.

What's the difference between Max-1 and Laser Lite?

The Max-1 is the universal bell shape at NRR 33; the Laser Lite is a self-fitting tapered plug at NRR 32 that is easier to seat for new users.
