About the ear tips

When bass is difficult to hear and high range sound jars the ear, there is a possibility that the ear tip fit is not appropriate. In order to enjoy music in accordance with the design of the earphone, it is important that the ear tip fits properly and there is a means of sealing the ear canal. In order to achieve the proper fit, please try the following method:

•  If there is any fitting discomfort with the default ear tips, please try with S or SS ear tips.
• Some users might have different ear canal sizes for the left and right ears. To achieve perfect fitting on both ears, please also try pairing ear tips with different sizes for left and right.

Points of Caution

• There is a risk of permanent hearing loss from extended use at excessive sound volumes. Please do not exceed 40 hours of use per week at a sound volume of 80 dB(A) or 5 hours per week at a volume of 89 dB(A).

Troubleshooting: When you think, “Is it broken?”

The battery charge is low

| For the safety of transportation from overseas, laws and regulations do not allow the internal battery to be fully charged at the time of shipping. For that reason, the voltage may fall below the level required for operation at the time the customer opens the package. Fully charging the battery before use may relieve this inconvenience. Please refer to “Power/Charging” on P.3 regarding the method for charging.

A touch sensor is not functioning

| The touch control

panel section has become soiled or wet

| In case the touch control panel section has become soiled or wet, the touch control panel may not function properly, and it may not be possible to operate the earphones     Please wipe the touch control panel
section with a soft, dry cloth to remove stains or moisture.
While playing music, sound (connection) is interrupted| Unstable connection caused by interference from an external factor| Bluetooth communicates using the 2.4GHz band. This band is used by other wireless standards such as Wi-Fi, etc., and so there is a possibility of receiving interference. Moreover, this 2.4GHz band does not penetrate liquids. There is the impact from humidity and rain, and the human body also contains liquid, so there are individual differences in connectivity.

Furthermore, it depends on the specifications of smartphones and other devices.

For that reason, switching OFF unused

Wi-Fi/Bluetooth settings on surrounding devices, etc. is a countermeasure. While outside, there is a possibility that moving a smartphone from inside a bag to a breast pocket, etc. or otherwise reducing the distance between devices may improve the

connection status.

III

| Based on the design specification, one side is the parent and the other side is the child, so the burden between left and right is

different

| Under the specification for Bluetooth earphones, communication generally takes place with one side as the parent and the other as the child.

As such, the child only communicates with the parent, but the parent communicates with the smartphone or other device and communicates with the child as well, and so there is a difference in the level of the burden borne by the left and right earphones. As a result, a difference in the battery consumption between the left and right may occur.

Maintenance

Gently remove any build-up from the mesh filter with the lip of a toothpick. Please take care to ensure that no foreign particles fall inside when doing so.
