  1. Initial Setup & Pairing

  1. Peel to Charge: Most YD03 units come with a small blue or clear plastic film on the earbud charging pins. You must remove this film for the earbuds to charge and turn on.

  2. Syncing: Take both earbuds out of the case. The LEDs will flash Red and Blue. Wait 3–5 seconds until only one earbud flashes; this means they have successfully paired with each other.

  3. Bluetooth Connection: Turn on your phone's Bluetooth and search for "YD03". Tap to connect.

  4. Auto-Connect: Once paired, the earbuds will automatically connect to your phone as soon as you lift the lid of the case.

  2. Using the Emergency Power Bank Feature

  The YD03 case is designed to give your mobile phone an emergency "boost" when you have no access to a wall outlet.

  • The Output Port: Locate the standard USB-A port (the larger one) on the side or back of the case.

  • Connecting: Plug your phone’s charging cable into the case and the other end into your phone.

  • Charging: The case will automatically start transferring power.

  • Note: This feature is meant for emergency use (e.g., getting 5–15% battery to make a call). Using it to fully charge a phone will deplete the case battery quickly.

  3. Smart Touch Control Commands

  The touch-sensitive area is located on the flat "head" of the earbuds.

  • Play/Pause: Single-tap either earbud.

  • Next Song: Double-tap the Right earbud.

  • Previous Song: Double-tap the Left earbud.

  • Volume Up: Triple-tap the Right earbud.

  • Volume Down: Triple-tap the Left earbud.

  • Answer/Hang Up: Single-tap during a call.

  • Reject Call: Long-press for 2 seconds.

  • Siri/Google Assistant: Long-press for 1.5 seconds until you hear a beep.

  4. Understanding the Mirror LED Display

  • Digital Number (Middle): Shows the remaining battery percentage of the Charging Case.

  • Left/Right Battery Bars: These represent the Earbuds. When the bars are moving, the buds are charging. When the bars disappear, the buds are fully charged.

  Care & Maintenance

  Tip	Action
  Mirror Cleaning	Use a soft cloth to wipe the mirror lid. Avoid using alcohol or harsh chemicals, as they can cloud the finish.
  Resetting	If only one earbud works, "Forget" the device from your phone, put both buds in the case, and take them out at exactly the same time.
  Safe Charging	Use the provided cable with a 5V/1A charger. Avoid using "Ultra-Fast" laptop chargers, as they can overheat the 1200mAh case battery.
