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. B1). 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

Because the headphones are of a high density enclosure, forcing them against your ears may result in eardrum damage. Avoid using the headphones where they are liable to be struck by people or other objects, such as a ball, etc. Pressing the headphones against your ears may produce a diaphragm click sound. This is not a malfunction. 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.
