Earphones will not turn OFF | 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" regarding the reset method. |
Charging case battery level is low LED Indicator does not light up while opening or closing the case | Normally, if the earphones are returned to an adequately charged case, the earphones will automatically turn OFF. If the earphones do not turn OFF, the battery power level of the charging case might be too low. Please try again after charging the charging case. Please refer to "Power / Charging" regarding the method for charging. | |
Using ear tips other than those included as accessories preventing the case from fully closed | Normally, if the earphones are returned to an adequately charged case, the earphones will automatically turn OFF. However, if ear tips other than provided 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 original ear tips. | |
Earphones cannot be charged | Metal contacts on earphone is not touching the pins on the charging case | Please ensure that the metal contacts are touching the pins on the charging case. In addition, if the golden terminal on the earphone or the charging case is dirty with sebum, etc., it may not be able to be charged. Dirt is hardly visible to the naked eye, so please wipe it off gently with a dry cotton swab. |
Charging case battery level is low (LED indicator does not light up while opening or closing the case) | Normally, if the earphones are returned to an adequately charged case, the earphones will automatically turn OFF and start being charged. If the charging does not start, the battery power level of the charging case might be too low. Please try again after charging the charging case. Please refer to "Power / Charging" regarding the method for charging. | |
The lid of the charging case is not properly closed | Normally, if the earphones are returned to an adequately charged case, the earphones will automatically turn OFF and start charging. If the lid of the charging case is closed and re-opened, the earphone units will turn ON and keep consuming power and lead to longer charging time. Please make sure the lid is properly closed while charging. | |
Using ear tips other than an accessory | Normally, if the earphones are returned to an adequately charged case, the earphones will automatically turn OFF and start being charged. However, if ear tips other than provided are used, there are cases in which they may interfere with the charging case and cause the earphones could not be charged. Please check to see whether the earphones start charging (LED lights up in Red) by using original ear tips. | |

Please wipe the touch control panel section with a soft, dry cloth to remove stains or moisture. |
Volume is too low / Cannot turn up the volume | Voice Through Mode is ON. | If the " Voice Through Mode" of the Ambient Sound Mode is turned on, the volume is automatically lowered and fixed. Please use the "BGM Mode" when you adjust with the Ambient Sound Mode. Switching the setting of Ambient Sound Mode can be done in the application. For more details, please check "What is the final CONNECT Application" section. |
Noise cancelling is not effective enough | Inappropriate ear tips size | If the 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". |
Earphones cannot be detected/paired | Earphones are not in the pairing mode | In some cases, performing a reset operation may fix the problem. Please refer to "Performing Factory Reset". |
Connected to a previously connected device | Please try performing the pairing operation again after having deleted the pairing information from the previously paired device. | |
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. |
While playing music, sound (connection) is interrupted | 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. |
Sound only comes out from one side | The left / right earphone pairing has been released | In some cases, performing a reset operation may fix the problem. Please refer to "Performing Factory Reset". |
The battery of one side of the earphones has depleted | Please return the earphone into the adequately charged charging case to charge it. Please refer to "Power / Charging" 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, 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. |
The ear tips come off easily | Non dedicated ear tips are used | Use of ear tips other than the dedicated ones may cause them to come off or remain in the ear canal during use. Be sure to use the dedicated ear tips. |
Lower volume on both sides or on a single side | Dust filter at the nozzle opening is clogged with build-up | Please try replacing the dust filters by referring to the "How to Replace Dust Filter" extra sheet which can be found together with the supplied dust filter in the accessories. During dust filter replacement, please always perform the replacement on both earphones. |
Buzzer noise from the earphones | Microphone howling effect occurs when microphones are half-covered | Howling effect is a common issue and it is not malfunction. Try to avoid using the earphones by having the microphones half-covered. If howling effect is occuring inside the charging case, please remove the earphones from the case or close the lid completely. |
