Note 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 listen with the
headphones while driving or
cycling
As your headphones reduce outside sounds, it
may cause traffic accident. Also avoid using them
where hearing must not be impaired, for example,
at a railroad crossing, a site of construction, etc.
