Peltor Optime 105 Twin Cup Earmuffs

Earmuffs must fully enclose the ears to seal against the head

The Optime 105 earmuffs feature a “double-shell” cup design that helps improve attenuation across the entire range of frequencies.

Earmuff Tips:

• Adjust the headband so cushions exert even pressure around the ears to get the best noise reduction.
• Pull hair back and out from beneath the cushions.
• Don’t store pencils or wear caps under cushions.
• Thick or poorly fitting eyeglass temples may also cause some loss in noise reduction.

Cushions can be cleaned with warm soapy water and rinsed thoroughly

• Do not use alcohol or solvents.
• Cushions normally need replacing at least yearly, or whenever they become stiff, cracked, or no longer seal.
• Don’t modify earmuffs in any way, and especially do not stretch or abuse the headbands as this will reduce your protection.
