Howard Leight By Honeywell Contoured-T Ear Plugs, 33dB Noise Reduction Rating NRR, Corded, M, Blue, Orange, PK 100

Metal-detectable ear plugs fit into the ear canal like standard ear plugs and have a metallic element so they can be sensed by a metal detector. They're commonly worn by workers in food manufacturing and pharmaceuticals processing plants so that ear plugs lost on the production line can be found to prevent contaminated products from leaving the plant. These detectable ear plugs provide hearing protection by expanding within the ear to form a seal that reduces sound levels to help prevent hearing loss in noisy work environments. Metal-detectable ear plugs are typically corded to help keep them from falling off and allow them to rest around your neck when they're not in use.

Contoured T-shaped ear plugs are slightly flattened at the end to provide a gripping point for handling and insertion.
