4.1 Choosing the Right Ear Tip
Selecting the correct ear tip size is crucial for comfort and sound quality. Your package includes small (S), medium (M), and large (L) ear tips. Experiment to find the size that provides a snug, comfortable fit without causing discomfort or whistling (feedback).
- A well-fitted ear tip prevents sound leakage and optimizes sound delivery.
- If you experience whistling, try a larger ear tip or ensure the current one is properly seated.

4.2 First Use and Fitting
- Charge Fully: Before first use, place both hearing aids in the charging case and ensure they are fully charged. Refer to the 'Charging' section for details.
- Select Ear Tip: Choose the appropriate ear tip size.
- Positioning: Gently place the hearing aid behind your ear, with the ear tube extending into your ear canal. Insert the ear tip into your ear canal until it feels secure and comfortable. The retention wire should sit against the outer ear to help stabilize the device.
- Initial Adjustment: Start with a lower volume setting and gradually increase it to a comfortable level. It may take some time to adjust to new sounds.
