One-Side Audio Fix

Sound Only Coming From One Side?

Start by checking the audio cable connection. A plug that is not fully inserted can cause the left or right side to lose sound.

Check the cable first.

Unplug the audio cable from the transmitter and your TV or audio source, then firmly reconnect both ends.

Test the headphones after each step. Stop once both sides are working.

Unplug the audio cable from the transmitter, then push it back in firmly.

Do the same at the TV or other audio source.

While audio is playing, gently move the cable near each plug.

If the missing side comes and goes, the cable or connection may be loose or damaged.

Turn the headphones off, turn them back on, then check whether sound is playing through both sides.

Try Another Cable or Audio Connection

This helps determine whether the problem is coming from the cable or the current TV audio connection.

Using AUX?

Try another compatible AUX cable, or test using the TV's Optical output if available.

Using Optical?

Reseat the optical cable firmly at both ends. If possible, test another optical cable or try AUX.

Check the Cable for Damage

Inspect both ends of the cable for damaged connectors or visible wear.

If moving the cable causes the sound to cut in and out, try a different cable.

Test With Another TV or Audio Device

Connect the transmitter to another compatible TV or audio source if one is available.

If both sides work on the second device, the original TV connection, cable, or audio output is the likely source of the problem.

If neither side is playing audio, use the full no-sound guide to check the TV connection, input selection, and audio settings.

Tell us which side has no sound, which TV connection you are using, and what you have already tried.
