Performance and Safety Tips
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 / on your ears, gradually
turn up the volume until you reach a comfortable
listening level.

Chart information obtained from www.nidcd.nih.gov/health/education/teachers/pages/common_sounds.aspx
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.
This decibel (dB) table compares some common
sounds and shows how they rank in potential
harm to hearing.
Get the most out of your equipment and enjoy
great audio performance even at safe levels. Our
headphones will allow you to hear more details at
lower volume levels than ever before.
Learn how to establish a safe listening level and
review other important safety guidelines from the
Consumer Electronics Association at www.ce.org.

Induced Hearing Loss (NIHL) and a comprehensive

Use Responsibly
Do not use headphones when it's unsafe to do so –
while operating a vehicle, riding a bike, 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.
Headphones "Break-in"
Break in time for headphones? We're kidding,
right? No we're not. Like any high performance
product, whether it's cars or headphones, they're
mechanical devices that settle in after use. Your
new headphones will sound incredible out of the
box, but will "mellow" out after use and sound even
better. We recommend playing them for 8 hours.
After 20 hours of playing, they should be fully
broken in. Enjoy.
