3M TRIZACT CLOTH BELT 307EA A45

The 3M E-A-R Classic earplugs are a leading choice for hearing protection, having set the industry standard as the first foam earplugs.

Their moisture-resistant foam is initially firm for easier insertion, softening once in the ear to expand and create a comfortable, custom fit. The slow-recovery feature allows ample time for insertion before the foam fully expands. These earplugs offer an attenuation rating of 29 dB, with a Noise Reduction Rating (NRR) that is recommended to be reduced by 50% for typical protection estimation. They are also compatible with the 3M™ E-A-Rfit™ Validation System to help confirm individual user protection levels.
