Adjusting the Fit

provide hearing protection when worn with the headband over the crown of your head.
(3) Slide the muffs carefully up or down to adjust for a firm, comfortable fit.
(4) Ensure the cushions seal tightly against your head with no interference from foreign objects between the ear cup and
your head (such as pencils or glasses temple arms). Spread the ear cups only enough to clear the ears. Do not return or
reshape the headband.
Note
For best performance, the earmuffs are fitted, adjusted and kept maintenance in accordance to manufacturer’s
instruction.
