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.
Limit the amount of time you listen. As the volume increases, less time is required before
your 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.
