On Using Headphones

Road safety – Do not use headphones while driving, cycling, or operating any motorized vehicle. It may create a traffic
hazard and is illegal in some areas. It can also be potentially dangerous to play loud music while walking, especially at
pedestrian crossings.
Preventing hearing damage – Avoid using headphones at high volume. Hearing experts advise against continuous, loud
and extended play. If you experience a ringing in your ears, reduce the volume or discontinue use.
