●
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.
