MAX-30 Corded Foam Earplugs | NRR 33 dB | Box of 100
The Howard Leight MAX-33 Corded Foam Earplugs provide industry-leading hearing protection for the loudest work environments. Featuring an exceptional Noise Reduction Rating (NRR) of 33 dB, these earplugs are recognized as the highest-rated disposable earplugs in the United States, making them a trusted solution for industrial safety programs where maximum noise attenuation is critical. Designed with an enhanced contoured shape and pre-shaped foam construction, MAX-33 earplugs deliver a secure, comfortable fit that resists backing out during active work. The smooth, hypoallergenic outer skin improves comfort for extended wear, while the corded design helps prevent loss and supports consistent use. Supplied in a box of 100 pairs, these earplugs are ideal for high-noise industrial, construction, and manufacturing environments.
Key Features:
- NRR 30 dB – high attenuation for most industrial high-noise environments.
- T-shaped large-flange design – more stable insertion for workers who struggle to achieve consistent seal with tapered plugs.
- Corded design – stays accessible between loud task periods.
- Box of 100 pairs – practical crew quantity.
Application
Manufacturing floors, construction sites, and any high-noise environment where crews have struggled to get a consistent seal with standard tapered foam plugs.
Buying Guide: T-Shape vs. Tapered Cylinder Foam Earplugs
Standard tapered foam earplugs require rolling to a narrow cylinder and deep canal insertion for rated seal performance. The MAX-30's T-shape relies on the large outer flange to create a seal — some workers find this easier to achieve consistently, particularly those with larger ear canal openings. If workers on your crew struggle with tapered plug insertion despite training, a flanged design like the MAX-30 is worth trialing.
FAQ - Howard Leight MAX-30 Ear plugs
How much noise protection do Howard Leight MAX-33 earplugs provide?
Howard Leight MAX-33 earplugs offer a Noise Reduction Rating of 33 dB, which is the highest rating available for disposable earplugs in the U.S. This makes them suitable for very high-noise work environments when worn correctly.
Are these earplugs comfortable for long shifts?
Yes. The smooth, hypoallergenic outer skin and pre-shaped foam design are specifically engineered to reduce irritation and maintain comfort during extended wear, even in demanding industrial settings.
Do these earplugs need to be rolled before insertion?
No. The MAX-33 earplugs feature a pre-shaped foam design, allowing for easier and more consistent insertion without the need for rolling, which helps improve fit reliability across users.
What is the benefit of the corded design?
The cord keeps the earplugs together when not in use, reduces loss, and allows workers to remove and reinsert them easily in environments with intermittent noise exposure.
Who should purchase the box of 100 pairs?
The box of 100 pairs is ideal for safety managers, contractors, industrial facilities, and procurement teams responsible for supplying hearing protection to multiple workers or job sites.
Does the T-shape affect NRR?
No — the NRR 30 rating reflects the attenuation achieved with correct insertion of the T-shaped design, tested to the same ANSI standard as other plug types.
