Key Features

  1. Fold out the earcups. 
  2. Place earcups over each ear. 
  3. Adjust the headband by sliding the headband up or down. 
  4. Firm Seal – Seal the cushions firmly against the head. 
  5. Avoid Obstructions – Do not allow hair to obstruct the ear or the earmuff’s secure fit in any way. 
  6. Cover Ear Completely – The earcups should never fit crooked or askew over the ear.


  • INSPECT – Regularly examine earcups and ear cushions for cracks and leaks—discard if earcups are visibly damaged or compromised. Replace ear cushions if damaged.
  • CLEAN – Wash earcups and ear cushions regularly with mild soap and water. They may not be dipped into water. Do not treat with any other substances, as the ear cushions may degrade and compromise use.
  • REPLACE – As ear cushions and foam inserts can degrade over time, replace these every 6-8 months under normal wear, or every 3-4 months with heavy use or in humid/extreme climates.


Listening to music, or any other sound, at a high volume over time can cause permanent damage to your hearing. Noise-induced hearing loss can occur even when we are enjoying music on a personal listening device. Exposures to high volume over time can cause permanent damage. Users should enjoy their favorite music safely and avoid potential hearing loss. When it comes to safe use of personal listening devices, we recommend that you listen responsibly, including listening at no more than 80% of a device’s maximum volume for a maximum of 90 minutes per day at such levels. If you listen at a lower volume, you can listen for a longer time. By contrast, at higher volumes, you should listen for a shorter time. Noise-induced hearing loss is 100% permanent, but 100% preventable.
