Because OTC devices do not come with professional fitting, users must be comfortable with basic troubleshooting.

• Feedback (Whistling): This often occurs if the ear tip is not seated correctly or if the volume is too high. Ensuring a snug fit with the correct size ear dome usually resolves the issue.

• Intermittency: If the sound cuts in and out, it is often due to a dying battery, a clogged wax guard, or moisture in the tubing.

• App Connectivity: For wireless devices, keeping the smartphone app updated and ensuring the device is properly paired via Bluetooth is crucial for accessing advanced customization features.
