Features:
Millions of workers are exposed to hazardous noise daily, but hearing loss can be prevented by using hearing protection.

EP-39 earplugs, disposable foam uncord or with cord in a poly bag, designed for most ear canals, 200 pairs per dispenser box, are your solution for hearing protection. EP-39 Earplugs feature a bell-shaped design that fits comfortably in the ear to help protect your hearing. Insertion only requires rolling down the soft foam earplug, placing it into the ear canal, and then allowing the low-pressure foam to expand for a snug yet gentle fit that helps block high noise levels. This earplug is a suitable choice for most of persons. Bright color allows supervisors to conduct a quick visual compliance check.

EP-39 earplugs have a Noise Reduction Rating (NRR) of 30dB. However, research suggests that many users will receive less noise reduction than indicated by the NRR due to variations in earplug fit, earplug fitting skill, and motivation of the user. It is recommended that the NRR be reduced by 50% to better estimate typical workplace protection.

EP-39 bell-shaped foam earplugs are popular choices in the market. They are single-use earplugs made of polyurethane foam, with a non-porous, soft texture, making them more resistant to dirt. The expandable super soft PU foam meets the needs of the individual wearer and is suitable for comfortable long-time wear.
