Features
• Earbud-style headphones deliver detailed and rich sound reproduction with deep bass.
• Silicone earbud housing for comfortable and soft fit in the ear.
• Robust sound achieved by use of high-power neodymium magnets.
How to use
Wear the earpiece marked R in your right ear and the one marked L in your left ear.
How to use the holder
Store the housing part as in illustration A. It prevents the cord from becoming tangled if
you store the ear receiver connected to a device such as WALKMAN®* in your pouch or
bag. When using the headphones, you can adjust the cord length by winding the cord
around the holder, as in illustration B.

How to install the earbuds correctly (see fig. C)
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. The M size earbuds are attached to
the headphones before shipment. If you feel the M size earbuds do not suit your ears,
replace them with the supplied S or L size earbuds. When you change the earbuds, install
them firmly on the headphones to prevent the earbud from detaching and remaining in
your ear.
Cleaning the earbuds
Remove the earbuds from the headphones, and wash them with a mild detergent solution.
