About Ear Tips

If you find the bass is lacking or the treble is grating, the ear tips may not be properly fitted. In order to make enough of the earphones’ potential, make sure the ear tips are positioned properly and keep the ear canals sealed. Please try the following instructions for proper fitting.

• Not only the standard M size, but also try different sizes.
• Trying larger sizes (L, LL) might be effective for small ears.
• The size of ear canals might be different from left to right. So try different size ear tips for the best fit for left and right ear canals.

  Prolonged use at excessive volume may result in permanent hearing loss. Do not exceed 40 hours/week at 80 dB (A) and 5 hours/week at 89 dB (A).

Troubleshooting: When you think, “Is it broken?

Earphones will not turn ON

| (Immediately after purchasing) Battery level 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 user 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.

Earphone batteries are depleted| Please return the earphones to the charging case to charge them. (In case the battery of the charging case has run out, please charge the charging case first.) Please refer to “Power/ Charging” on P.3 regarding the method for charging.
The touch control panel has not been touched for adequate time| Please touch and hold the touch control panel until the power turns ON. Please refer to “Power ON” on

P.4 regarding the method for turning the earphones ON.

An error has occurred due to improper operation| In some cases, performing a reset operation may fix the problem. Please refer to “Factory Reset Method” on P.7 regarding the reset method.
Earphones will not turn OFF|

The touch control panel has not been touched for adequate time

| Please touch and hold the touch control panel until the power turns OFF. Please refer to “Power OFF” on P.4 regarding the method for turning the earphones OFF.
Charging case battery level is low| Normally, if the earphones are returned to an adequately charged case and the case closed, the earphones will automatically turn OFF. If the earphones do not turn OFF, the battery level of the charging case might be too low. Please try again after charging the charging case. Please refer to “Power/ Charging” on P.3 regarding the method for charging.
Using ear tips other than those included as accessories|

Normally, if the earphones are returned to an adequately charged case and the case closed, the earphones will automatically turn OFF. However, if ear tips other than those included as accessories are used, there are cases in which they may interfere with the charging case and cause the earphones could not be turned OFF. Please check to see whether the earphones turn OFF by using the original ear tips.

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.
Problem| Cause| Remedy
---|---|---
Earphones cannot be charged| Metal contacts on earphone are not touching the pins on the charging case| If the earphone’ s metal contacts are touching the pins of an adequately charged charging case, the LED Indicator will blink slowly. If this is not happening, please remove the earphone, clean the metal contacts and return it to the charging case properly again.
Charging case battery level is low| Normally, if the earphones are returned to an adequately charged case, the earphones will start being charged. If the charging does not start, the battery level of the charging case might be too low. Please try again after charging the charging case. Please refer to “Power/ Charging” on P.3 regarding the method for charging.
Using ear tips other than those included as accessories| Normally, if the earphones are returned to an adequately charged case, the earphones will start being charged. However, if ear tips other than those included as accessories are used, there are cases in which they may interfere with the charging case and cause the earphones to become unable to be charged. Please check to see whether  the  earphones charge by using the original ear tips.
In case it takes time to charge| The output of the USB adapter being used for charging is low| In case you are using the USB port on a PC, etc., there are cases in which the output is low and it may take more time to charge than the publicly listed value.

As such, please use a 5V/1A USB adapter when charging this product.

Earphones cannot be detected/ pairec| Earphones are not in the pairing mode| In some cases, performing a reset operation may fix the problem. Please refer to “Factory Reset Method” on P.7.
Has automatically been connected to a previously connected device| Please try performing the pairing operation again after having deleted the pairing information from a previously paired device.
While playing music, sound (connection) is interruptec| 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., so there is a possibility of receiving interference. Moreover, this 2.4GHz band does not penetrate liquids. There is an impact of 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.

Please refer to “Factory Reset Method” on P.7.
The battery of one side of the earphones has depleted| Please return the earphone to the adequately charged charging case and close the case to charge it. Please refer to “Power/ Charging” on P.3 regarding the method for charging.
Battery consumption is fast for one side of the

earphones only

| 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, 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.

Noise Cancelling is not effective enough| Inappropriate ear tip size| If the size of ear tips are not proper, noise cancellation will not adequately work. Please try various sizes other than the standard M size and use the most appropriate size. For more information, please check “About Ear Tips” on P.7.

Maintenance

Please take safety precautions and gently remove any build-up from the dust filter by using the tip of a cotton swab.

Disposal Regulation
The rechargeable batteries built into the equipment are recyclable.
During disposal, please follow the instructions from your local municipal government and do not attempt to disassemble the product.
