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.

Precautions

• 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.

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.
