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.

“…a typical person can safely listen to an iPod for 4.6 hours per day at 70% volume.”
“…knowing the levels one is listening to music at, and for how long
is extremely important.”

Use Responsibly

Do not use headphones when it’s unsafe to do so – while operating a vehicle,
crossing streets, or during any activity or in an environment where your full
attention to your surroundings is required.

It’s dangerous to drive while wearing headphones, and in many places,
illegal because it decreases your chances of hearing life-saving sounds
outside of your vehicle, such as another car’s horn and emergency vehicle sirens.

Please avoid wearing your headphones while driving. Use one of Monster’s
FM transmitters to listen to your mobile media devices instead.

Learn how to establish a safe listening level and review other important
safety guidelines from the Consumer Electronics Association at www.ce.org.
