    Question

    Why do the lights on my SoundCore Life Note earbuds not turn on when I place them in the charging case?

    Answer

    If the lights on your SoundCore Life Note (A3908) earbuds do not turn on when placed in the charging case, it usually indicates a connection or power issue rather than a "serious problem." Please try the following troubleshooting steps:

    • Clean the Charging Pins: Use a dry, soft lint-free cloth or a cotton swab with a small amount of rubbing alcohol to clean the metal charging contacts on both the earbuds and the pins inside the charging case. Dust or earwax buildup often prevents a proper connection.
    • Check the Case Battery: Ensure the charging case itself is charged. Plug the case into a power source using a certified USB-C cable. The case indicators should light up to show it is receiving power.
    • Verify Seating: Make sure the earbuds are properly seated in their slots. Sometimes third-party ear tips can prevent the earbuds from making contact with the charging pins.
    • Reset the Earbuds: If the earbuds are unresponsive, place them in the case and follow the reset procedure (typically holding the button on both earbuds for several seconds while in the case, though specific steps may vary).

    If the lights still do not appear after cleaning and charging the case, you may contact Soundcore support at service@soundcore.com or call +1 (800) 988 7973 (US).

    Question

    How do I fix pairing issues when only one earbud is working on my SoundCore Life Note A3908?

    Answer

    To resolve the issue where only one earbud is playing audio or the earbuds are not pairing with each other, you should perform a reset of your Anker SoundCore Life Note A3908. Follow these steps:

    1. Clear Pairing History: Go to the Bluetooth settings on your mobile device and delete/forget all pairing records for "Soundcore Life Note".
    2. Place in Case: Place both earbuds into the charging case and ensure they are charging (the LED indicators should be on).
    3. Reset: Press and hold the button on both earbuds simultaneously for 3 seconds. The LED indicators will flash red 3 times and then turn white.
    4. Re-pair: Take both earbuds out of the charging case at the same time. They will automatically pair with each other. Once the LED on one earbud flashes rapidly and the other flashes slowly, they are in pairing mode.
    5. Connect to Phone: Turn on Bluetooth on your device and select "Soundcore Life Note" to reconnect.

    If the issue persists, ensure that both earbuds are fully charged and that there is no debris on the charging pins inside the case or on the earbuds themselves.

  3. I put the headphones in their box and it does not turn on the light to charge, is it supposed that when I put them they start charging and when I take them out of the box they go into pairing mode but it does not do that automatically as before someone knows what it is?

    Question

    Why are my SoundCore Life Note earbuds not charging or entering pairing mode automatically when placed in or removed from the case?

    Answer

    It sounds like your earbuds are not making a proper connection with the charging pins inside the case. When the earbuds don't "realize" they are in the case, they won't charge or turn off, and consequently, they won't trigger the automatic pairing mode when you take them out. Please try the following steps:

    • Clean the Charging Contacts: Use a dry, lint-free cloth or a cotton swab with a small amount of rubbing alcohol to clean the copper contact points on both the earbuds and the pins inside the charging case. Dust or earwax buildup often prevents a solid connection.
    • Check the Case Battery: Ensure the charging case itself is charged. If the case battery is completely dead, it cannot signal the earbuds to turn off or enter charging mode.
    • Reset the Earbuds: If cleaning doesn't work, try a reset:
      1. Place the earbuds into the charging case and make sure they are being charged.
      2. Press and hold the button on both earbuds for 3 seconds. The LED indicators will flash red 3 times and then turn white.
    • Verify Seating: Ensure the earbuds are seated firmly in the case. Sometimes third-party ear tips can prevent the earbuds from sitting deep enough to touch the pins.

    If the lights still do not turn on after cleaning, the battery in the case or earbuds may have failed. You can contact Soundcore support at service@soundcore.com or call +1 (800) 988 7973 for further assistance.

  4. Is there any way to turn the volume on 1 up? One of my earbuds are quiet while the other one isn’t.

    Question

    How can I fix an imbalance where one earbud is quieter than the other on my SoundCore Life Note A3908?

    Answer

    If one of your Anker SoundCore Life Note (A3908) earbuds is quieter than the other, it is often caused by a connection sync issue or debris blocking the speaker grill. Please try the following steps:

    • Reset the Earbuds: This is the most common fix for volume or pairing imbalances.
      1. Place both earbuds in the charging case and ensure they are charging.
      2. Press and hold the button on both earbuds for 3 seconds until the LED indicators flash red 3 times and then turn white.
      3. Delete the Bluetooth pairing record from your device and pair them again.
    • Clean the Speaker Grill: Earwax or dust buildup can significantly muffle the sound of a single earbud. Carefully clean the metal mesh with a dry, soft lint-free cloth or a cotton swab dipped in a tiny amount of rubbing alcohol.
    • Check Device Balance: Ensure your phone or computer's audio settings are not set to favor one side (check Accessibility or Audio Balance settings).

    If the issue persists, you can contact Soundcore support at service@soundcore.com or call +1 (800) 988 7973 (US) for further assistance under your 18-month warranty.

    Manuals+ clarified question
    Question

    Why is the volume on my right SoundCore Life Note earbud much lower than the left, even after multiple resets?

    Answer

    If you have already attempted to reset your Anker SoundCore Life Note A3908 earbuds and the right earbud still has significantly lower volume, please try the following troubleshooting steps:

    • Clean the Earbud Mesh: The most common cause for low volume in one earbud is earwax or debris buildup on the metal mesh filter. Use a cotton swab with a small amount of rubbing alcohol to gently clean the mesh, or use a soft-bristled brush to remove any blockages.
    • Check for Moisture: Ensure there is no sweat or water trapped inside the earbud, as this can muffle the sound.
    • Test with Another Device: Pair the earbuds with a different phone or computer to rule out software-based balance issues on your primary device.
    • Contact Support: Since you have already tried resetting the device without success, there may be a hardware fault. You can contact Soundcore customer service at service@soundcore.com or call +1 (800) 988 7973 (US) or +44 (0) 1604 936200 (UK) for warranty assistance.
