Corded foam ear plugs

These corded ear plugs use soft polyurethane foam to reduce noise by 25 dB. Each pair is paper wrapped and the cord keeps the plugs together when not in the ear. The product meets ANSI S3.19-1974 and comes in a pack of 100 pairs.

Workers needing reusable hearing protection

Suitable for environments where a 25 dB reduction is required and a cord prevents loss. Not intended for users who need a higher attenuation rating or a metal detectable plug for food processing.

Noise Reduction Rating 25 dB

Questions about this item

What ear canal size does the pod-shaped plug fit?

The product lists Ear Plug Size M, so the pod-shaped plug is sized for medium ear canals.

Does the vinyl band interfere with other head-worn gear such as hard hats or earmuffs?

The vinyl band sits behind the neck, leaving the top and sides of the head free for hard hats, helmets or over-the-head earmuffs.

How can I confirm the plugs are seated correctly after insertion?

When inserted properly the soft foam expands to fill the canal and the yellow pod ends sit flush with the ear opening, giving a noticeable drop in ambient noise.
