Quartet 2 - 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

● Do it 3-5 times if possible to reset the headphones internally

2.  Check the audio cable is fully inserted into your TV/audio source and to the transmitter base

● make sure you hear a click

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

4.  Power OFF then ON the headphones and test again

5.  If your using 3.5mm AUX connection , try to plug the Aux cable directly to your headphone Aux port and use it as wired to test .

Most Common Reason

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

TIP :

Test on another TV/device ( this help us determine if the issue persists across multiple devices )
