headphones to block out background environmental
noise. By blocking background environment noise, noise
cancelling headphones should allow you to hear the
music at lower volumes than when using earbuds.
•
Limit the amount of time you listen. As the volume
increases, less time is required before you hearing could
be affected.
•
Avoid using headphones after exposure to extremely loud
noises, such as rock concerts, that might cause
temporary hearing loss. Temporary hearing loss might
cause unsafe volumes to sound normal.
•
Do not listen at any volume that causes you discomfort. If
you experience ringing in your ears, hear muffled speech
or experience any temporary hearing difficulty after
listening to your portable audio device, discontinue use
and consult your doctor.
