the most...
The new CH-3 headset will bring hearing protection and
communication in noisy environments into a new level of performance.
Communication has never been easier.
3M Science. Applied to life.™
New design for enhanced
comfort during long hours of use
Newly designed dual mold cups give a modern and slim look together with the new bright
yellow color for enhanced visibility. Cup size is reduced while still retaining high attenuation and
comfortable space for ears. The reduced size also contributes to less weight which improves
comfort during long hours of use.
We have designed an all new headband with improved flexibility to better fit different types of
head shapes. Headband cable is easily detachable from the headband for easy replacement.

*Note: U.S. EPA specifies the NRR as the measure of
hearing protector noise reduction. However, 3M makes
no warranties as to the suitability of the NRR for this
purpose. 3M strongly recommends personal fit testing
of hearing protectors. Research suggests that users may
receive less noise reduction than indicated by the
attenuation label value(s) on the packaging due to
variation in fit, fitting skill, and motivation of the user.
Refer to applicable regulations for guidance on how to
adjust attenuation label values. It is recommended that
the NRR be reduced by 50% to better estimate typical
protection.
