The stay-in design uses a thermoplastic elastomer that is pliable to fit the hollow of your
ear. If it does not stabilize, adjust its position.
Installing 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 type, 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 or type. Confirm the size of the earbuds by checking the color
inside (see fig.
-
for hybrid silicone rubber earbuds and
-
for noise isolation
earbuds).
When you change the earbuds, install them firmly on the headphones to prevent the
earbud from detaching and remaining in your ear.

Notes
Prolonged use of the noise isolation earbuds may strain your ears due to their snug fit. If you have
experience discomfort or pain in your ears, discontinue use.
The pressure-relieving urethane cushion is extremely soft. Therefore, do not pinch or pull the
urethane cushion. If the urethane cushion is broken or detached from the earbuds, it will not take its
correct position and the earbuds will lose their noise isolation function.
The pressure-relieving urethane cushion may deteriorate due to long-term storage or use. If the
pressure-relieving power is lost and the urethane cushion becomes hard, the earbuds may lose their
noise isolation function.
Do not wash the noise isolation earbuds. Keep them dry, and avoid accumulation of water in the
pressure-relieving urethane-cushions. Not doing so may cause early deterioration.
To detach an earbud (see fig.
-
)
While holding the headphone, twist the parts inside of the earbud and pull the earbud
off.
Tip
If the earbud slips and cannot be detached, wrap it in a dry soft cloth.
To attach an earbud (see fig.
-
)
Push the parts inside of the earbud into the headphone until the projecting part of the
headphone is fully covered.
Carrying the headphones (see fig.

Place the headphones in the inner case.
2
Wind the cord around the side of the inner case and store the plug, and then
put the inner case in the carrying case.

Do not close the case forcibly without winding up the cord. Otherwise, the cord may break.

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.
Handle the driver units carefully.
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.
Store the earbuds where children cannot reach in order to prevent from accidental
ingestion or choking.
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.
Optional replacement earbuds can be ordered from your nearest Sony dealer.
