Care / Maintenance / Storage
* Cushions should be wiped clean after each use.
* Cushions & foam pads should be clean with mild soap and water or
alcohol swabs and allow to air dry.
* It is recommended to check cushions and foam pads at frequent intervals
for cracking and leakage as these may deteriorate with use.
Replace ear muffs as and when necessary.
* Store in cool, dry place in included container. Do not leave in direct sunlight.
Note:
* for optimum performance, the cups of the earmuff must completely cover your ears and should seal tightly against the head. Anything that interferes with the seal such as long hair, thick or poorly fitting spectacles. pencils, or caps will lessen the protection. Do not bend or reshape the headband as this will cause a loose fit and sound leakage.
