Responsible Listening
Caution!: Avoid potential hearing loss.
Damage to hearing occurs when a person is exposed to loud 
sounds over time. The risk of hearing loss increases as sound is 
played louder and for longer durations. Prolonged exposure to 
loud sounds (including music) is the most common cause of 
preventable hearing loss. Some scientific research suggests that 
using portable audio devices, such as portable music players and 
cell phones, at high volume settings for long durations may lead 
to permanent noise-induced hearing loss. 
This includes the use of headphones (including headsets, 
earbuds, 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 potential hearing problem varies. Additionally, 
the amount of sound produced by a portable audio device varies 
depending on the nature of the sound, the device settings, and 
the headphones that are used. As a result, there is no single 
volume setting that is appropriate for everyone or for every 
combination of sound, settings, and equipment.
You should follow some common sense recommendations when 
using any portable audio device:
•
Always turn the volume down before plugging the earphones into an
audio source.
•
Set the volume in a quiet environment and select the lowest volume at
which you can hear adequately.
•
Be aware that you can adapt to higher volume settings over time, not
realizing that the higher volume may be harmful to your hearing.
•
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. By blocking background environment noise, noise cancelling 
headphones should allow you to hear the music at lower volumes than 
when using earbuds.
