device, the device settings, and the headphones. You should follow some
commonsense recommendations when using any portable audio device:
s
Set the volume in a quiet environment and select the lowest volume at
which you can hear adequately.
s
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.
s
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.
s
Limit the amount of time you listen. As the volume increases, less time is
required before your hearing could be affected.
s
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.
s
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.
