Notes on headphones
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.
Do not use headphones while driving and
cycling, etc.
As headphones reduce outside sounds, they may cause a
traffic accident. Also, avoid listening with your headphones
in situations where hearing must not be impaired, for
example, a railroad crossing, a construction site, etc.
