  • Check the batteries are placed in correct polarities.
  • Batteries are completely used up.
  • Start playback after checking that the power is turned on for the TV or audio playback device used.
  • Raise the headphones' sound volume. If no sound can be heard even after raising the sound volume, lower the volume and check other items.
  • Shorten the distance between the headphones and transmitter.
  • Check to be sure no other electronic device using the 2.4 GHz band is located near the headphones or transmitter. If such a device is present, move it as far as possible away from the transmitter and headphones.
Sound is distorted.
