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.
●Donotlisten atanyvolume that
causes you discomfort. If you
experience ringing in your ears,
hear muffled speech or
experience any temporary
hearing difficultyafter listening
to your portable audio device,
discontinue use and consult
your doctor.
