About noise isolation earbuds
Supplied noise isolation earbuds provide a snug
fit for effective attenuation of ambient noise.
Notes
Prolonged use of snugly fitting earbuds may
strain your ears. If you experience discomfort,
discontinue use.
The pressure-relieving urethane cushion is
extremely soft. If it breaks or detaches from
the earbuds, it will not take its correct
position and the earbuds will lose their noise
isolation function.
The urethane cushion may deteriorate over
time. If the pressure-relieving power is lost
and the urethane cushion hardens, the
earbuds may lose their noise isolation
function.
Do not wash the earbuds. Keep them dry,
otherwise they may deteriorate quickly.
About hybrid silicone rubber
earbuds
Keep earbuds clean. To clean the earbuds, wash
them with a mild detergent solution.
Removing the headphones
After use, remove the headphones slowly.
Note
Headphones are designed to fit closely in your
ears. If the headphones are pressed hard while in
use or taken off too quickly, they may cause
injury.
Wearing headphones may produce a diaphragm
click sound. This is not a malfunction.
Precautions
High volume may affect your
hearing. For traffic safety, do
not use while driving or
cycling.
Install the earbuds firmly. If an
earbud accidentally detaches
and is left in your ear, it may
cause injury.
Do not leave the stereo headphones in a
location subject to direct sunlight, heat or
moisture.
Note on static electricity
Static electricity accumulated in the body may
cause mild tingling in your ears.
To minimise the effect, wear clothes made from
natural materials.
