Precautions in using the headphone
Do not use the headphone while driving an automobile or riding a bicycle. It is not only dangerous, but also against
the law. To avoid an accident, do not turn up the volume of the headphones too high while walking.
It is not recommended that you use the headphones at a high volume for an extended time as this may cause hearing
damage.
