 in). If you wind more, 

the cord comes off from the cord adjuster easily.)

Do not wind the plug or split section of the cord, as it will strain the cord and may cause a wire break.

Wearing the headphones (see fig. )

There is a tactile dot on the unit marked  to distinguish the left side.

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.

After use, remove the headphones slowly.

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.

Design and specifications are subject to change without notice.

  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.

  Do not leave the stereo headphones in a location subject to direct sunlight, heat or 

moisture.

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 authorized Sony 

retailer or www.sony.com.
