The Howard Leight Corded Ear Plugs Super Leight Foam, model R01180 (UPC 033552011804), are disposable hearing protection devices designed for adult users requiring high noise attenuation in shooting, industrial, and general high-noise environments. Each retail pack contains 3 pairs of corded foam earplugs with a Noise Reduction Rating (NRR) of 33 dB, making them suitable for environments where substantial sound reduction is required when properly fitted.

Noise Reduction and Performance
These Super Leight corded foam ear plugs are rated at 33 dB NRR, a high level of attenuation for single-use earplugs when correctly inserted and used in accordance with fitting instructions. The high noise reduction rating helps reduce exposure to impulse and continuous noise typical of shooting ranges, construction sites, machinery operation, and other loud environments. Industrial Automation+1
The plugs are intended for single-use; discarding them after one or a few uses helps maintain both hygienic performance and consistent acoustic properties over time. Honeywell Consumer Store
Construction and Materials
The Super Leight corded ear plugs use polyurethane foam as the main plug material. This foam is designed to be:
Low-pressure and compressible, allowing the plug to be rolled and inserted easily into the ear canal
Slow-recovery, expanding gently to conform to the ear canal shape for a secure acoustic seal
Closed-cell on the outer surface, helping to resist dirt and debris build-up during handling and wear Industrial Automation+1
Key material characteristics:
Plug material: Polyurethane foam
Cord: Flexible cord designed to be worn behind the neck, allowing earplugs to hang when not in use
Color: Red product classification for this retail configuration; color coding assists with easy identification and compliance checks in work or range environments Sportsman's Outdoor Superstore+1
Design and Ergonomics
The earplug body is pre-shaped and contoured in a bell-like profile to match the natural shape of the inner ear. This design supports: Industrial Automation+1
Improved in-ear comfort over longer wear periods
Reduced tendency to back out of the ear canal when properly inserted
Consistent seal quality across a wide range of adult ear canal sizes
The corded design connects the two plugs via a flexible cord that rests comfortably behind the neck:
Helps prevent loss or dropping when plugs are temporarily removed
Allows quick re-insertion between noise exposures
Reduces the need for separate storage between uses within a work session
The combination of soft foam, contoured shape, and corded retention is intended to provide a balance of comfort, convenience, and stable attenuation for adult users.
Fit, Sizing, and Intended Users
These Howard Leight Super Leight foam ear plugs are specified as “Adult, one size fits most”, and are suitable for a wide range of adult ear canal sizes when properly compressed and inserted. Honeywell Consumer Store+1
Fitting characteristics:
Roll the earplug between clean fingers to compress the foam into a small cylinder.
Insert gently into the ear canal while pulling the ear upward and outward to straighten the canal.
Hold in place briefly until the foam expands and seals.
Proper fit is essential to achieve the rated 33 dB NRR; improper insertion or partial insertion can significantly reduce effective attenuation.
Applications and Use Scenarios
While these plugs are marketed strongly toward shooting sports, they are also suitable for other high-noise environments where single-use foam earplugs are appropriate, such as:
Indoor and outdoor shooting ranges
Hunting environments with intermittent impulse noise
Industrial and manufacturing facilities with continuous machinery noise
Construction and power tool operation
Loud events where disposable hearing protection is preferred
The corded, behind-the-neck configuration is particularly useful in scenarios where users frequently transition between protected and unprotected listening (e.g., communicating between shooting strings or during intermittent machine operation).
Hygiene, Disposal, and Storage
The earplugs are designed as single-use or limited-use disposables:
The closed-cell outer skin helps resist dirt and debris build-up during a typical wear period. Industrial Automation+1
Once plugs are visibly soiled, lose elasticity, or become damaged, they should be discarded and replaced.
For best hygiene, store unused earplugs in the original packaging or a clean container away from moisture, oils, and contaminants.
Used plugs should not be washed and re-used; doing so may alter the foam’s structure and compromise attenuation and comfort.
