Important Performance and Safety

Tips for your Headphones

Listen Responsibly

To avoid hearing damage, make sure that the volume on your music player

is turned down before connecting your headphones. After placing headphones

in your ears, gradually turn up the volume until you reach a comfortable

listening level.

Noise levels are measured in decibels (dB), exposure to any noise at or above

85 dB can cause gradual hearing loss.

Monitor your use; hearing loss is a function of loudness versus time. The louder

it is, the less time you can be exposed to it. The softer it is, the more time you

can listen to it. Refer to the chart* on the following page.

This decibel (dB) table compares some common sounds and shows how they rank

in potential harm to hearing.
