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.
