Bose recommends following the General Care and Maintenance
instructions in this guide. With normal use, items such as windscreens

Cleaning instructions

General cleaning
Gently wipe the outside surfaces of the headband, connectors, plastic
parts, and headband cushion, using a soft cloth moistened with water
and mild soap. Take special care when cleaning the ear cushions and
the outside surfaces of the earcups, as described below.
Earcup TriPort™ openings
The earcup TriPort openings, shown in Figure 7, must remain clean and
free of debris. Ensure that ports are clean before each flight. When
wiping down the headset, be sure not to force any dirt or debris into
the ports. Carefully use tweezers, if necessary, to remove foreign
matter that may be lodged in the ports. Do not blow air into or vacuum
the ports.
Ear cushions
To extend the life of the ear cushions, wipe them clean in the manner
described in General cleaning above. Regular cleaning of the
earcushions is recommended. It is also recommended that you replace
the earcushions annually.
If, however, more vigorous cleaning is required, remove the ear cush-
ions from the earcups, as shown later in this section, to ensure that the
protective inner screen is not damaged during the cleaning process.
Do not immerse ear cushions in water or any other liquid.
