How to use
Wearing the headphones (see fig. )
1
Wear the earbud marked  in your right ear and
the one marked  in your left ear (see fig. -).
2
Hook the headphones around your ears
(see fig. -).
There is a tactile dot on the unit marked  to
distinguish the left side.
3
Clip around your ear lobes by rotating the
headphones (see fig. -).
4
Adjust the earbuds to comfortably fit your ears.
Move the clip as shown in the figure (-) for a
comfortable fit.
How to use the cord slider (see fig. -)
Move up and down to change the split position of the cord.
After you use the headphones, keep them with the cord
slider high positioned to avoid entangling the cord.
How to install 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 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. Confirm
the size of the earbuds by checking color inside
(see fig. -).
When you change the earbuds, turn to install them firmly
on the headphones to prevent the earbud from detaching
and remaining in your ear.

Precautions
 Please keep your headphones clean at all times especially
inside the rubber earbud (see fig. ).
If any dust or ear wax 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.
 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.
 It may be advisable to remove earrings or pierced
accessories before using the headphones.
 Do not bend the ear-clip excessively. If it is bent 90
degrees or more, it may break.
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.
EP-EX10 is available (sold separately) as optional
replacement earbuds.
EP-EX10 offers 4 types of the earbuds: SS, S, M and L.
Optional replacement earbuds in other colors can be
ordered from your nearest Sony dealer.
