Do not listen at extremely high volume levels.  Extended, high-volume  
listening can lead to permanent hearing loss.  Follow these guidelines to 
protect your hearing, especially when you use headphones. 
 
    Always start by setting the volume to the lowest level possible before 
    you begin listening.  Put the headphones on, then gradually increase 
    the volume as necessary. 
 
    Once you set the volume, do not increase it.  Over a period of time,  
    your ears adapt to the volume level, so a volume level that does not  
    cause discomfort might still damage your hearing.
