“… 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

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
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
