QuietComfort 3 Acoustic Noise Cancelling headphones feature rotating earcups that fold flat for easy, convenient storage.
CAUTION: The earcups rotate only in one direction. Incorrectly rotating the earcups can damage the headphones.
Using the carrying case
The carrying case provides safe storage for your headphones and accessories. The foam tray holding the battery and charger is removable, allowing you to store other items, such as an MP3 player, in the case.
Note: To maximize battery life, always charge the battery before storing it and never store the battery in the charger.
