Hint
When the earbuds become worn, contact the nearest Sony dealer or Sony Service Center.
If the earbuds become dirty, remove them from the player. Then, hand-wash the earbuds with a neutral detergent. After you wash
the earbuds, drain off the water and reattach the earbuds.
If the player does not fit your ears even after you have adjusted the mounting position of the earbuds, you can replace the arc
supporters.
