Opera Plus - Fix One-Side Sound

One-sided sound is usually caused by a loose or incomplete cable connection, so audio only reaches one side.

Quick Check

1. Unplug the audio cable from the transmitter and plug it back in firmly

2. Check the cable is fully inserted into your TV/audio source

3. Wiggle the cable slightly and see if sound cuts in/out

4. Power OFF then ON the headphones and test again

If it still doesn’t work:

• Try another cable or port (AUX / Optical)

• Test with another device

Most Common Reason

The audio cable isn’t fully connected, so only one channel (left or right) is working.

Still not working?

• Check for bent or damaged cable tips

• Try a different input method (optical vs AUX)

• Test on another TV/device to confirm
