Warning: Hearing Safety
Set the volume loud enough to hear clearly in quiet surroundings, and no louder.
Do not increase the volume after you start listening. Your ears can adapt over time so that
high volume sounds normal, but the high volume may still damage your hearing.
•
Do not increase the volume to block out outside noise. The combination of outside noise
and sound from your headphones can damage your hearing. Sealed or noise-canceling
headphones can reduce outside noise so that you don’t have to turn up the volume.
If you can’t understand someone nearby speaking normally, turn down the volume. Sound
that drowns out normal speech can damage your hearing. Even with sealed or noise-canceling
headphones, you should be able to hear nearby people speak.
Minimize Your Time Listening to Loud Sound
The more time you spend exposed to loud sound, the more likely you are to damage your
hearing. The louder the sound, the less time it takes to damage hearing.
• Minimize your time listening to loud sound. At maximum volume, listening to music on

• Even lower volumes can damage hearing if you are exposed for many hours.
• All of the sound that you are exposed to during a day adds up. If you are exposed to
other loud sound, it takes less time listening at high volumes to cause hearing damage.
• To safely use the device with no time limit, keep the volume low enough that you can
carry on a conversation with people nearby.
