 in your right ear and the one marked 

L

 in your left ear.

How to use the carrying case (see fig. 

A

)

1

Press the case lightly on either side, as shown in the illustration to open. Hold
the bottom of the case to not drop it.

2

Place the headphones in the case, and wind the cord around the side of the
case. The plug can be placed at the rear of the case.

How to install the earbuds correctly (see fig. 

B

)

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.

hear a click (See. fig.

• To disconnect the extension cord, pull it out by the plug, not the cord, to avoid

damaging inner conductors.

• Please keep your headphones clean at all times especially inside the rubber earbud (see

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.
