noise-cancelling headphones to block out background environmental
noise. By blocking background environment noise, noise cancelling
headphones should allow you to hear the music at lower volumes than
when using earbuds.
Limit the amount of time you listen. As the volume increases, less time
•
is required before you 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.
