Before getting into it, take a look at this VIDEO GUIDE, and make sure you connect the transmitter(tower) to the correct audio output on your TV. If it still can't work, please follow the steps below and let us figure out what exactly is wrong:
1. If you using AUX/RCA, please wire headphone up to TV's audio out port and turn on TV to listen, can you hear sound from both sides?
If YES, go to 2.
2. Is the audio cable connecting the transmitter and your TV/audio source is securely Plugged in at BOTH ends?
If YES, go to 3.
3. If you try to wiggle the audio cable or unplug and plug the audio cable, will the sound back to stereo sometimes?
If NOT, go to 4.
If YES, pls try another audio cable. If it works by another cable, then it is faulty cable issue. If it still not working, go to 4.
4. Plug and unplug the audio cable to the aux/3.5mm port on headphone 2-3 times, does it work?
If NOT, pls contact firstname.lastname@example.org for replacement.
