Before first use, fully charge the earbuds and the charging case.

- Connect the USB-C charging cable to the charging port on the case and the other end to a USB power source (e.g., computer, wall adapter).
- The LED display on the charging case will indicate the battery level. A full charge for the case takes approximately 1.5 hours.

2. Wearing the Earbuds
The X13 earbuds feature an ear hook design for a secure and comfortable fit, especially during physical activity. Three sizes of silicone eartips (S/M/L) are provided to ensure optimal comfort and sound isolation.
- Choose the eartip size that best fits your ear canal. A good seal is crucial for sound quality and bass response.
- Gently insert the earbud into your ear canal.
- Adjust the ear hook over the top of your ear until it feels secure and comfortable. The ear hook should rest snugly behind your ear.
- Ensure the earbud is firmly seated in your ear to prevent it from falling out during movement.
