How to install the earbuds correctly
(see fig.

)

If the earbuds do not fit your ears correctly, low-bass sound may not
be heard. To enjoy better sound quality, change the earbuds to
another size, or adjust the earbuds position to sit on your ears
comfortably and fit your ears snugly.
If the earbuds do not fit your ears, try another size. Confirm the size
of the earbuds by checking color inside (see fig.

When you change the earbuds, turn to install them firmly on the
headphones to prevent the earbud from detaching and remaining in
your ear.

Precautions

• 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.

• Listening with headphones at high volume may affect your

hearing. For traffic safety, do not use while driving or cycling.

• 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.

EP-EX10A is available (sold separately) as optional
replacement earbuds.
