Ingco Hand Tools Earmuff - HEM3328

Summary

The Ingco HEM3328 Industrial Earmuff blocks heavy machinery noise with a 33dB SNR shell. ABS plastic construction stops high-frequency waves before they reach the ear canal. This version increases the SNR from 24dB to 33dB and the NRR to 26dB compared to the HEM01.

Key Features

1. Double-shell Construction: High-density ABS plastic housing. High-frequency noise stays outside the ear cup.
2. Stainless Steel Wire: Tension-based adjustment mechanism. The frame maintains a tight seal against the skull.
3. Included Earplugs: One spare pair comes in the box. Wear these to manage road dust and noise simultaneously.
4. ANSI/EN Compliance: Certified under ANSI3.19 and EN352-2 standards. Verified ratings prevent permanent hearing loss during industrial shifts.
5. Padded Headband: Soft cushion across the top arch. Pressure stays off the scalp during long work hours.
