The High Attenuation Headset CH 5

The High Attenuation Headset CH 5 is a top-of-the-line product that offers one of the highest Noise Reduction Rating (NRR) values on the market, with an impressive NRR of 31dB*. This makes it an excellent choice for individuals working in environments with high noise hazards, such as those in close proximity to generators or turbines.

One of the key features of this headset is its ability to provide professional occupational hearing protection while still allowing users to monitor external radio communication sources. This is crucial for individuals who need to stay connected and communicate effectively in their work environment.

The Flex connector of the High Attenuation Headset CH 5 offers a wide range of options for customizing the headset to fit different radios available on the market. This ensures compatibility and ease of use for users who may have different radio communication systems in their workplace.

In addition to its exceptional functionality, this headset also comes in a high visibility color. This feature enhances safety in exposed environments, making it easier for others to spot individuals wearing the headset and reducing the risk of accidents or mishaps.

*NOTE: It is important to note that 3M strongly recommends the fit testing of hearing protectors. If the NRR is used, it should be derated by 50% to ensure accurate protection levels.
