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.
