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 and the Deafness Research Foundation at www.drf.org.
