If you experience one side sound from the headset, there are 2 external reasons that may cause the issue:
- Faulty audio cable
- Defective audio out port
So before we arrange the replacement to you, please help check below points >
1. Please make sure the audio cable that's used to connect the source such as TV and the transmitter is good and plugged tightly on both ends. Or try another audio cable.
2. Please test to plug the transmitter to your phone, will you hear sound from one side or both sides from the headset? If both sides have sound, the issue should be with the audio out port of the source device.
If above 2 reasons are excluded, please contact firstname.lastname@example.org for free replacement as long as the device is still under warranty period.
