Protective earmuffs are designed to protect hearing in moderate noise environments. They are adapted to both professional work, where hearing protection must be protected, and home workshops. Soundproofing allows you to communicate and hear sound signals. The signal-to-noise ratio of the headphones is 30 dB. Insulation made of high-density G-TECH foam provides very good protection against intense sound and comfort of use even for many hours. Thanks to the adjustment of the pressure spring, the earmuffs can be precisely adjusted to the head, without causing pressure.
