Aura Focus - How to Fix One-Side Sound Issue?

Before You Start: If sound only comes from the LEFT or RIGHT earbud, the other earbud may have a charging issue or may have lost its connection to the transmitter.

In most cases, simply restarting both earbuds can restore sound to both sides.

Step 1 – Restart Both Earbuds

Check the charging LED:

1. Place both earbuds inside the charging case.
2. Make sure both earbuds are properly seated and their charging LEDs turn Solid RED.
3. Leave both earbuds charging for a few minutes.
4. Remove both earbuds together and wait 5–10 seconds for automatic reconnection.

Step 2 – Reset Both Earbuds

If restarting doesn't restore sound to both sides, reset both earbuds to clear their previous connection.

1. Follow the Aura Focus Earbuds Reset Guide.
2. After resetting, remove both earbuds from the charging case and check whether sound works on both sides.

Step 3 – Manually Reconnect Both Earbuds to the Transmitter

Check the LED indicators:

1. On the transmitter, press and hold the Add Device button for 2 seconds until the LED flashes ORANGE rapidly.
2. Place both earbuds inside the charging case and keep the lid OPEN.
3. Press and hold the charging case button for 3 seconds until the earbuds flash RED rapidly.
4. Keep the earbuds close to the transmitter and wait until the earbud LED turns Solid BLUE for 1 second, then OFF.

Once connected, remove both earbuds from the case and test the sound.
