".... 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."

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.
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 is 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 an FM transmitter 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 and the Deafness Research Foundation at www.drf.org.
