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. Optime I is the natural choice when you need to use 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. It is first-rate 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 = 26dB, High Frequency = 30dB, Medium Frequency = 24dB, Low Frequency = 15dB.
