Product Description
Instruction for use:
-With the band in correct position over the head, adjust the height of the cups so they fully enclose the ears, and the cushions exert equal pressure around the ears.
-It is important that the cushions seal tightly against the head. For best protection ear cushions should seal firmly against the head. Anything that interferes with seal such as long hair( pull back to the extent possible), thick or poorly fitting eyeglass temples, pencils, or caps, will lessen the protection.
-Do not bend and reshape the headband as this will cause a loose fit and sound leakage.
How does the headphone work?
The ability of a passive earmuff to attenuate a signal is based on the materials used. The material and structure of the earmuff device is used to decrease the sound level that is transmitted through the ear canal. Materials, such as a cupped foam coated in hard plastic, will block sound due to the thick and dampening properties of the foam.
Where you can use your ear defender well:
Earmuffs can be used in the workplace or recreationally for loud activities, e.g., concerts, shooting firearms, heavy machinery, mowing, etc.
