Precautions
 Please keep your headphones clean at all times especially inside the rubber earbud.
(see fig. )
If any dust or ear wax is inside the earbud, you may experience some listening
difficulties.
 Listening with headphones at high volume may affect your hearing. For traffic safety,
do not use while driving or cycling.
 Do not put weight or pressure on the headphones as it may cause the headphones to
deform during long storage.
 The earbuds may deteriorate due to long-term storage or use.
 Install the earbuds firmly onto the headphones. If an earbud accidentally detaches and
is left in your ear, it may cause injury.
Note on static electricity
In particularly dry air conditions, mild tingling may be felt on your ears. This is a result
of static electricity accumulated in the body, and not a malfunction of the headphones.
The effect can be minimized by wearing clothes made from natural materials.
