The headband style hearing protectors offer great comfort and quality to all professional users. A light and durable headband construction with soft cushions and easy size adjustment provides a perfect fit for all head sizes. Protection level 3 is suitable for high to very high noise levels, between 100-115 dB. Fortunatly a rare environment for most workers, but the best and only choice when nothing else will do. Protection level 3 is also the best choice when the noise is dominated by low frequencies, a type of noise that masks out speech and other important sounds, as well as causing stress and nausea.
