Optime I is very versatile protection, characterised by its lightness. Despite being so lightweight, it is the best imaginable protection. We have combined a low profile with generous inside depth. This makes it easy to team with other equipment and means that the ear rests comfortably. All-round protection for both short and long spells. The wide, comfortable sealing rings are filled with a unique combination of fluid and foam, which gives optimum sealing and low contact pressure, ensuring the best possible comfort even during long periods of use. For use in environments with moderate industrial noise, such as workshops, sheet-metal shops and printing works, but can also be used to good effect outdoors, for instance when mowing the lawn or in connection with hobby and leisure activities. SNR 27dB, High Frequency = 32dB, Medium Frequency = 25dB, Low Frequency = 15dB.
