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.

  Please keep your headphones clean at all times especially inside the rubber earbud.

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.

  Store the earbuds where children cannot reach in order to prevent from accidental 

ingestion or choking.

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.
