If you found the sound only coming from one side of the headphone, please:
1) Ensure the audio cable connecting the transmitter and your TV/audio source is FULLY plugged at BOTH ends.
2) If the above 2 steps still not help, please try another audio cable.
If you still experience one side sound, then contact email@example.com for free replacement pls.
