• New technology with double casing that minimizes resonance in the holder casing, to more easy to understand speech and signals.
• The sealing rings are broad and filled with soft plastic foam for the best fit and low ontact pressure.
• Good inner space for ear.
• With CE standard.

Pull the cups outward and position the hearing protector over your ears so that the cushions fully enclose the ears and seal tightly against the head.

Insert the headband into the hard hat’s slots until they snap into place. When in use, the wire bands must be pushed inward until you hear a “click” on both sides, indication a shift from “stand-by” to “usage” position. Make sure the cups and wire bands are not in contact with the inner lining or the edge of the hard hat when in the “usage” position, otherwise this may lead to leakage.

Note: The cups can be placed in three positions:

• Usage position
• Stand-by position
• Storage position

Important: For best protection ear cushions should seal firmly against the head. Anything that interferes with the seal such as long hair(pull back to the extent possible), thick or poorly fitting eyeglass temples, pencils, or caps, will lessen the protection. Do not bend and reshape the headband as this will cause a loose fit and sound leakage.
