- Insert and Twist: Gently insert each earbud into your ear canal and twist slightly until it feels snug and comfortable. The earbud should sit securely without causing pressure.
- Test the Fit: Play some audio and check for any sound leakage. If the audio sounds thin or lacks bass, adjust the earbuds or try a different eartip size.

- Use the included cleaning kit or a cotton swab to gently remove any earwax or debris from the earbud nozzles and charging contacts.
