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
