5. Wearing the Earbuds

For optimal comfort and sound quality, especially during sleep, proper fit is crucial. The Sonora Mini earbuds come with various ear tip sizes to ensure a secure and comfortable fit.

5.1. Selecting the Right Ear Tips

• Experiment with the different ear tip sizes provided. A good fit will create a seal in your ear canal, enhancing sound quality and noise isolation.
• If you experience discomfort or poor noise isolation, try a different size.

5.2. Inserting the Earbuds

1. Gently insert each earbud into its corresponding ear (L for left, R for right).
2. Rotate the earbud slightly until it feels snug and comfortable in your ear canal. The earbud should sit flush with your outer ear, minimizing protrusion for side sleepers.
