Check if your WH-RF400 Wireless Home Theater Headphones turn on after completing each step:

  • Make sure that the positive and negative ends of the batteries are facing in the correct direction.
    • The charging indicator on the transmitter will light up red for 15 seconds and turns off if the batteries are not installed properly.
  • Try to use two standard AAA batteries.
    • Your headphones turn on if the light indicator turns green.


  • If the signal is weak or there's no input within four minutes, the transmitter will turn off automatically.
  • If your headphones still don't turn on after following the steps above, repair may be required. Go to Product Repair.
