Road safety
Do not use headphones/earphones while

vehicle. It may create a traffic hazard and is
illegal in some areas.  It can also be
potentially dangerous to play your headsets
at high volume while walking, especially at
pedestrian crossings. You should exercise
extreme caution or discontinue use in
potentially hazardous situations.
Preventing hearing damage
Avoid using headphones/earphones at high
volume. Hearing experts advise against
continuous, loud and extended play. If you
experience a ringing in your ears, reduce
volume or discontinue use.
Consideration for others
Keep the volume at a moderate level. This
will allow you to hear outside sounds and to
be considerate to the people around you.
Maintenance
