Precautions
High volume may affect your
hearing. For traffic safety, do not
use while driving or cycling.
Because the headphones are of a high
density enclosure, forcing them against
your ears may result in eardrum damage.
Avoid using the headphones where they are
liable to be struck by people or other
objects, such as a ball, etc.
Pressing the headphones against your ears
may produce a diaphragm click sound. This
is not a malfunction.
Optional replacement earpads can be
ordered from your nearest Sony dealer.
