Replacing the cushions (video included)

Replacing earcup cushions

As a general rule, ear cushions should be replaced every six months or every 350 hours of use. They may need to be replaced more often if:

The headset is worn over a full beard or heavy whiskers

The headset is subjected to severe temperature extremes—such as would occur if you park your aircraft outside in severe cold or heat

Excess strain is placed on the cushions because of improper storage

Indications that the ear cushions need replacing include:

Flaking of the outer covering

Cuts or tears

Flattening of the cushion, reducing the effectiveness of the seal

To replace an ear cushion, follow these steps:

Grasp the ear cushion skirt where it folds into the slot on the earcup

Gently pull the ear cushion skirt up and away from the earcup

Properly position the replacement ear cushion against the earcup

Tuck an edge of the ear cushion skirt into the slot cushion flange. Be careful not to fold the skirt over

Work the remainder of the skirt into the slot completely around the earcup

Grasp the ear cushion and adjust its position to remove folds in the skirt and wrinkles in the cushion

Replacing the headband cushion

The headband cushion is designed to give the maximum level of comfort to your headset. Bose recommends that you replace the cushion after regular care and maintenance fails to restore the wool pile to its original size and shape.

To replace the headband cushion, follow these steps:

On a protected surface, turn the headset upside down. Remove the old cushion from the headband

While still holding the headband open, align the center of the new cushion with the center of the headband and press firmly from the center toward the outside

Note: Removing and attaching the headband cushion may be easier if a second person holds the headset open.
