•
When using headphones, turn the volume down if
you cannot hear the people speaking near you or if
the person sitting next to you can hear what you are
listening to.
•
Do not turn the volume up to block out noisy
surroundings. If you choose to listen to your portable
device in a noisy environment, use noise-cancelling
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.
