• Cleaning: Wipe the exterior of the earmuffs with a damp cloth and mild soap. Do not immerse in water.

• Storage: Store in a cool, dry place away from direct sunlight and extreme temperatures. The 360° swivel ear cups allow for compact storage.
• Inspection: Periodically check ear cushions and headband for cracks, hardening, or other signs of wear. Replace worn parts if necessary to maintain noise reduction performance.

Troubleshooting

If you experience issues with your Dr.meter Noise Reduction Earmuffs, consider the following:

• Reduced Noise Reduction: Ensure the earmuffs are properly positioned and create a tight seal around your ears. Check for any gaps or obstructions (e.g., thick hair, glasses arms). Inspect ear cushions for wear or damage.
• Discomfort: Adjust the headband and ear cups to find a comfortable fit. Ensure the headband is not too tight or too loose.
• Earmuffs Not Staying On: Verify the headband is adjusted correctly for your head size. The earmuffs should fit snugly without being overly tight.
