Convenient cord adjuster supplied
How to use
Using the supplied cord adjuster (see fig.
)
You can adjust the cord length by winding the cord on the cord adjuster.
(The cord can be wound to the cord adjuster up to 50 cm. If you wind more, the cord
comes off from the cord adjuster easily.)
1
Wind the cord.
2
Push cord into slot hole to secure in place.
Note
Do not wind the plug or split section of the cord, as it will strain the cord and may cause a wire break.
Using the extension cord (see fig.
)
Insert the stereo mini plug fully into the jack until you hear a click.
Wearing the headphones (see fig.
)
1
Determine right and left headphone and hold them as in the illustration.
There is a tactile dot on the unit marked
to distinguish the left side.
2
Fit the headphones into your ears snugly, as in the illustration.
3
Adjust the headphone to fit snugly in your ear.
Tip
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
colour 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.

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.

（導線最多可繞到導線長度調節器上達 50 cm。如果在達到最大長度下繼續捲繞，則導
線會很容易從導線長度調節器中滑出。
）
1
捲繞導線。
2
將導線推入槽孔以固定到位。
注意
請勿捲繞插頭或導線的分叉部分，否則可能會拉壞導線並造成線芯斷裂。
如何使用延長線（

注意
長期使用噪音隔離耳塞可能會拉傷耳朵，因為耳塞緊貼耳朵。如果耳朵感到不適或疼痛，請暫停使
用。
氨基鉀酸酯釋壓泡棉非常柔軟。因此，切勿擠壓或拉出氨基鉀酸酯泡棉。如果氨基鉀酸酯泡棉損壞
或與耳塞分離，則耳塞位置不正確，將失去噪音隔離功能。
氨基鉀酸酯釋壓泡棉可能會因為長期存放或使用而損壞。如果失去釋壓能力，且氨基鉀酸酯泡棉變
硬，則耳塞可能失去噪音隔離功能。
請勿清洗噪音隔離耳塞。使耳塞保持乾燥，並避免氨基鉀酸酯釋壓泡棉積水。否則可能會導致過早
老化。
拆掉耳塞的方式（見圖
-
）
拿著耳機，然後轉動耳塞內側部分，把耳塞拔出來。
