Tips & Best Practices for Use

1. Fit and Seal
   Ensure the ear cups fully enclose the ears without gaps. Hair, glasses, or jewelry can interfere — adjust the headband accordingly.
2. Inspect Regularly
   Check cushions and seals often. Replace if cracked, hardened, or misshapen to maintain protection.
3. Keep Clean
   Wipe surfaces with a mild soap solution. Avoid strong solvents or immersing in liquids which may degrade seals.
4. Store Properly
   Keep in a clean, dry place when not in use. Avoid crushing or deforming the cups.
5. Use in Conjunction with Other PPE
   When wearing other gear (helmets, face shields), confirm that the earmuffs still seal correctly.
