There are a few simple things you can do to maintain your headphones.
Caring for your Bose® product
To prolong the life of your ear cushions, gently pat the cushions with a soft cloth after extensive use. This will remove any oils or perspiration that may remain on the cushions
Do not place any stress or pull on the input cable. Doing so may shorten the life of your headset
Be sure the earcup ports are clear of lint, dust and debris. Do not allow moisture to get inside the earcups
Periodically wipe the headphones with a damp cloth
To maintain white headphones, wash using a soft cloth dampened in a mixture of dish detergent and water. Clean the exterior of the earcups with a slightly dampened soft cloth.
Note: While the headphone materials are resistant to stains, the headband may require occasional spot cleaning.
