the device settings and the headphones.
You should follow some commonsense
recommendations when using any
portable audio device:
Set the volume in a quiet
environment and select the lowest
volume at which you can hear
adequately.
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.
