The earphones 3MTM PELTORTM OptimeTM II offer high-level acoustic protection, even from very low frequencies. Tested according to EN 352:2020, our headphones reduce noise levels up to 31 dB. They are ideal in noisy and difficult environments with a considerable level of noise, such as airports and construction sites, and during agricultural work. Designed with comfort, the wide space within the cups helps to reduce moisture formation and heat accumulation. Wide and soft bearings reduce pressure around the ears.
