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.

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.
