The Bilsum™ Thunder T3H® earmuff is a great example and designed to mount onto most types of safety helmets. When the T3H® is being used the earcups snap into place and when not needed you can simply swing them back into a convenient position. The Bilsum Thunder earmuffs offer plenty of comfort and like our other products they can be worn for long periods of time.
Consider our De Walt™ Interceptor® earmuffs with their NRR of 26. A higher NRR equates to better protection against loud noises but it also causes greater isolation which can be dangerous in some environments.
Before making a purchase it's very important to make sure the NRR matches your environment. Our Leightning™ L3H® earmuff has a NRR of 27 and designed for use in tough industrial worksites. The Leightning™ L3H® features tough steel wire construction and can withstand heavy daily abuse.
NRR = "Noise Reduction Rating" a unit of measurement used to determine the effectiveness of hearing protection devices to decrease sound exposure within a given working environment.
