Therefore, delete the pairing information for this product from your smartphone or other device before attempting to pair again. ※ After resetting, the volume will return to factory default and Noise Cancelling mode will be enabled again.

If you feel that the bass is weak or high frequencies sound harsh, the ear tips may not be fitted properly. To enjoy the intended sound quality of the earphones, it is important to attach the ear tips correctly and ensure that your ear canal is properly sealed. Please try the following methods to achieve the correct fit:

・If you feel discomfort when wearing them, try the SS or M sizes as well.
・Since the size of the ear canal can differ between the left and right ears, try using different ear tip sizes for each side.

・Cause1：(Immediately after purchasing) Battery level is low
For 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, voltage may fall below the level required for operation at the time the customer opens the package. Please refer to “Charging” above.

・Cause2：Earbud’ s battery is depleted
Please return the earbuds into the charging case and close the case to charge them. (In case the charging case power has run out, please charge the charging case first.) Please refer to “Charging” above regarding the method for charging.

・Cause3：An error has occurred due to improper operation
In some cases, performing a reset operation may fix the problem. Please refer to “Performing Factory Reset” above.

・Cause4：Charging case battery is depleted
If opening and closing the charging case lid does not activate the LED indicator, it means that the charging case battery is completely depleted. In this state, opening the lid will not automatically turn on the earphones, so please charge the earphones. For detailed charging instructions, refer to the “Charging” section above.

・Cause5：The insulation sticker stays intact
Please peel off the insulation stickers attached to the metal contact areas of the left and right earbuds.

・Cause1：Charging case battery is depleted
If opening and closing the lid of the charging case does not cause the LED indicator on the case to respond, this indicates that the battery of the charging case is completely depleted. In this state, even if you place the earbuds in the charging case and close the lid, the earbuds will not turn off automatically. Please charge the earbuds. For details on how to charge, refer to the section “Charging” above.

・Cause2：(When the earbuds do not turn off even when placed in the charging case) You are using eartips other than the supplied ones.
Normally, when the earbuds are placed in the charging case with sufficient battery and the lid is closed, the earbuds automatically turn OFF and begin charging. However, if you are using eartips other than the included ones, they may interfere with the charging case, preventing proper charging and causing the earbuds not to turn OFF. Please check whether the earbuds operate normally with the supplied eartips.

・Cause1：Metal contacts on earbud are not touching the pins on the charging case
Please ensure that the insulation stickers attached to the metal contacts are peeled off, and that the metal contacts are touching the pins in the charging case.

・Cause2：Charging case battery is depleted
Normally, when the earbuds are placed in the charging case with sufficient battery and the lid is closed, the earbuds automatically turn OFF and begin charging. If charging does not start, the charging case itself may not have enough remaining battery. Please charge the charging case and try again. For details on how to charge, refer to the “Charging” section above.

・Cause3：The lid of the charging case is not closed
If the lid of the charging case is not fully closed while the earphones are stored inside, charging will not start. Please ensure that the lid of the charging case is properly closed.

・Cause4：Using eartips other than the supplied ones.
Normally, when the earbuds are placed in the charging case with sufficient battery and the lid is closed, the earbuds automatically turn OFF and begin charging. However, if you are using eartips other than the included ones, they may interfere with the charging case, preventing proper charging and causing the earbuds not to turn OFF. Please check whether the earbuds operate normally with the supplied eartips.

・Cause1：Earbuds are not in the pairing mode
In some cases, performing a reset operation may fix the problem. Please refer to “Performing Factory Reset” above.

・Cause2：( If pairing has been performed once ) Connected to a previously connected device
Please try performing the pairing operation again after having deleted the pairing information from the previously paired device.

Cause：The output of the USB adapter being used for charging is low
When using a USB port on a PC or similar device, the output may be low, resulting in longer charging times than the rated value. Therefore, when charging this product, please use a USB adopter capable of supplying 5V/500mA or more.

Cause：Unstable connection caused by interference from 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 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.

・Cause1：The left/right earbud pairing has been released
In some cases, performing a reset operation may fix the problem. Please refer to “Performing Factory Reset” above.

・Cause2：The battery of one side of the earbuds has depleted
Please return the earbuds into the adequately charged charging case and close the case to charge it. Please refer to “Charging” above regarding the method for charging.

Cause：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 devices and communicates with the child as well, and so there is a difference in the level of burden borne by the left and right earphone. As a result, a difference in the battery consumption between the left and right may occur.

Cause：The output of the USB adapter being used for charging is low
When using a USB port on a PC or similar device, the output may be low, resulting in longer charging times than the rated value. Therefore, when charging this product, please use a USB charger capable of supplying 0.5A (500mA) or more.

・Cause1：The touch control panel has become soiled or wet
In case the touch control panel has become soiled or wet, the touch control panel may not function properly, and it may not be possible to operate the earbuds. Please wipe the touch control panel section with a soft, dry cloth to remove stains or moisture.

・Cause2：Touch control is turned OFF
When touch control is OFF, tap operations are disabled.To enable touch control, tap either the right or left earbud 5 times to switch it ON. Touch control will also turn ON if you place both earbuds back into the charging case, close the lid, and open it again.

Cause：Ear tips do not fit properly
If the ear tip size does not fit your ears, noise cancelling will not function effectively.　Please try different sizes in addition to the pre-installed M size and use the size that best fits you.　For more information on ear tips, please refer to the “About the Ear Tips” section above.

原因：Dust filter at the nozzle opening is clogged with build-up
Dirt on the filter can cause a decrease in sound pressure. Before wearing the earbuds, please clean your ears and take care to avoid getting the filter dirty. If dirt does accumulate on the filter, gently clean it by lifting the dirt with a small brush or a cotton bud.

Please carefully remove any debris adhering to the dust filter by gently lifting it off, for example by using the tip of a cotton swab. Be sure to work carefully to prevent debris from falling inside the unit. Also, please use a cotton swab or similar tool to clean the airflow port.
