The available operating time is short, the battery power does not last long.

  • The available operating time of the battery is shorter when the noise canceling function/Ambient Sound Mode is on.
  • Depending on the settings for the headset functions and usage conditions, the speed of energy consumption for the rechargeable battery may vary between the left and right headset units. However, this is not a malfunction.
  • When you have finished using the headset, be sure to set the headset units into the charging case. If the headset is placed in the pockets, etc., the headset recognizes that the headset is worn, and it may not turn off after a period of time has passed.
  • Be sure to close the charging case lid to prevent the battery of the charging case from being consumed.
  • When you are talking on the phone on the headset via a Bluetooth connection, the available battery operating time becomes shorter than when listening to music.
