Medley Pebble : How to Fix One-Side Sound Issue?

Before You Start: If sound only comes from the LEFT or RIGHT earbud, the earbuds may have lost their connection to each other or to the transmitter. Turn OFF nearby Bluetooth devices and keep both earbuds close to the transmitter during troubleshooting. Follow these steps to reset and reconnect both earbuds.

Step 1 – Reset the Earbuds

Watch the video for step-by-step reset instructions, or follow the written guide below.

1. Place the earbud with no sound onto the transmitter.
2. Wait a few seconds for the other earbud to flash RED & BLUE, indicating the earbud is in pairing mode.
3. Once the LED flashes RED & BLUE, quickly press the MFB button based on the batch/lot number:
   • Before T24L2: Press 2 times.
   • T24L2 or later: Press 5 times.
4. Check the LED: PINK briefly → Flashing BLUE means the reset is complete.
5. Place the reset earbud back onto the transmitter.
6. Remove both earbuds together and keep them close to each other.

Step 2 – Reset the Transmitter

1. Make sure the transmitter is ON.
2. Press and hold the RESET button for 5 seconds.

This clears the transmitter's previous pairing information.

Step 3 – Reconnect Both Earbuds

1. Keep both earbuds within 1–3 feet of the transmitter.
2. Wait approximately 5 seconds for them to reconnect automatically. Do not press any buttons.
3. Put on both earbuds and check whether sound works on both sides.
