Optime™ II ear defenders provides sealing rings which are filled with a unique combination of liquid and foam. The result is an optimum seal with low contact pressure, which provides snug comfort even during long term use. The sealing rings have ventilation channels and are covered with a soft, hygienic foam. Optime™ II is a suitable choice for environments with substantial industrial noise or construction machinery, airports and agricultural work.
