Setup

1. Charging the Earbuds and Case

Before first use, fully charge the earbuds and the charging case. The charging case features a dual LED display to indicate the power level of both the earbuds and the case itself.

1. Place the earbuds into the charging case, ensuring they are correctly seated. The earbuds will begin charging automatically.
2. Connect the USB-C charging cable to the charging port on the case and plug the other end into a compatible USB power source (e.g., wall adapter, computer USB port).
3. The LED display on the charging case will show the charging status. A full charge for the case typically takes about 1.5 hours.
4. Once fully charged, disconnect the charging cable. The earbuds provide 6-8 hours of playback on a single charge, and the case offers an additional 5 full recharges.

2. Bluetooth Pairing

The earbuds are designed for automatic connection after the initial pairing process.

1. First-time Pairing:
   1. Open the charging case. The earbuds will automatically power on and enter pairing mode.
   2. On your Bluetooth-enabled device (smartphone, tablet, etc.), go to the Bluetooth settings.
   3. Search for available devices and select "C16" (or similar name) from the list.
   4. Once connected, you will hear a confirmation tone, and the earbuds will be ready for use.
2. Subsequent Connections: After the first successful pairing, simply open the charging case and take out the earbuds. They will automatically connect to the last paired device if Bluetooth is enabled on that device and it is within range.
3. Single Earbud Mode: Either earbud can be used independently. Simply take one earbud out of the case, and it will connect in mono mode. The other earbud can remain in the case or be used later for stereo sound.

Operating Instructions

1. Wearing the Earbuds

Maintenance

Proper maintenance ensures the longevity and optimal performance of your Kuizil Wireless Earbuds.

• Cleaning:

  Regularly clean the earbuds, especially the ear tips and charging contacts, with a soft, dry, lint-free cloth. For ear tips, you may use a slightly damp cloth with mild soap and water, ensuring they are completely dry before reattaching. Do not use harsh chemicals or abrasive materials.

• Water Resistance (IP7):

  The earbuds have an IP7 waterproof rating, meaning they can withstand sweat, rain, and minor water splashes. They are not designed for submersion in water. Do not wear them while swimming or showering. If they get wet, wipe them dry immediately before placing them back in the charging case.

• Storage:

  When not in use, store the earbuds in their charging case to protect them from dust, dirt, and physical damage. Store the case in a cool, dry place away from direct sunlight and extreme temperatures.

• Battery Care:

  To preserve battery life, avoid fully discharging the earbuds or charging case frequently. Charge them regularly, even if not in constant use. Avoid leaving them uncharged for extended periods.
