3M E-A-Rsoft metal detectable earplugs AV were specifically developed for the food industry, where it is critical to keep earplugs from contaminating products and processes. The cord is NOT metal detectable 3M E-A-Rsoft metal detectable earplugs AV feature an implanted stainless steel ball bearing in the plug, so they can be recognized by most metal sensing systems. The cord is NOT metal detectable.

The NRR may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided, if you do not fit test the earplugs with a system like E-A-Rfit. 3M is leading the advancement of hearing Conservation.
