and Bluetooth® or other wireless devices). Exposure to very loud sound has also
been associated in some studies with tinnitus (a ringing in the ear),
hypersensitivity to sound and distorted hearing. Individual susceptibility to
noise-induced hearing loss and other potential hearing problems varies.
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
