Sound is interrupted
The following describes possible solutions when the sound is interrupted.
Try the methods below to see whether they help to resolve the problem.
Communication with the device may sometimes be unstable.
Changing the position or orientation of the device
If there is an obstructing object (our body, metal, wall, etc.) between the device and the earphones, use the device upon moving it to a position that allows for most stable communication, such as by inserting it into the rear pocket instead of the front pocket.
Also, orientation of the device may have a significant impact on communication.
Use the connected device in a position or orientation that allows for the most stable communication.

If there are frequent sound interruptions, charge the earphones.
Charging the earphones
-
Open the charging case
-
Insert the earphones into the charging case
-
Close the charging case
-
Charge the charging case and earphones
After the earphones are inserted into the charging case, the power of the earphones will automatically turn off.
5V TYPE
The indicator on the charging case starts flashing, indicating that charging has started.
During charging of the charging case, the indicator on the case will continue to flash. When charging is complete, all the indicators light up.

Communication of the device may sometimes be unstable depending on the environment.
Using the earphones at a different location
Sound may be interrupted if the earphones are subject to radio interference at crowded areas or beside microwave ovens and other electronic equipment that emits radio waves.
Also, radio waves are transmitted and received both directly and via reflections from walls and other objects during Bluetooth® communication, so sound may also be interrupted even at places with good visibility and no obstructing objects.
This is a characteristic of Bluetooth® communication and is not a malfunction.
If there are frequent sound interruptions, use the earphones at a different location.
