  • Move closer to the IR transmitter or adjust your seating position for better line-of-sight.
  • Check for any strong light sources or electronic devices that might interfere with the IR signal.
  • Ensure batteries are not low.
• No Sound in Wired Mode:
  • Ensure the 3.5mm audio cable is fully inserted into both the headphones and the audio source device.
  • Check the volume on the audio source device.
