MORE INFORMATION
The amount of sound produced by a portable audio device varies depending on the
nature of the sound, the device, 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. 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.
