Caution
DO NOT operate any motor vehicle or heavy machinery while listening to or wearing your headphones. Doing so is not only dangerous to you or others
but illegal in many states. Listening or wearing headphones reduces your ability to hear sounds around you such as emergency vehicle sirens or the horn
from another motorist.
It is not recommended to use headphones when cycling, running or walking in heavy traffic areas, where your full attention is necessary for your
safety.Always use your headphones responsibly in every situation.
