Charging the Earbuds and Case

Operating Instructions
Wearing the Earbuds
Select the silicone eartips that provide the most comfortable and secure fit for your ears. Gently insert the earbuds into your ear canals and twist slightly to ensure a snug seal. A proper fit is crucial for optimal sound quality and active noise cancellation performance.

Touch Controls
The Sudio A1 Pro earbuds feature intuitive touch controls for managing your audio and calls. Specific touch gestures (e.g., single tap, double tap, triple tap, long press) control functions such as play/pause, skip tracks, answer/end calls, and activate voice assistant. Refer to the quick start guide included in the box for a detailed list of touch control functions.
Active Noise Cancellation (ANC)
The Active Noise Cancellation feature reduces ambient noise, allowing for a more immersive listening experience. To activate or deactivate ANC, use the designated touch control gesture on the earbuds. When ANC is active, battery life may be reduced to approximately 3 hours of playtime.

Making and Receiving Calls
The Sudio A1 Pro earbuds are equipped with two built-in microphones for clear call quality. Use the touch controls to answer, end, or reject calls. Ensure the earbuds are properly connected to your device via Bluetooth to utilize call functions.

Maintenance
Water Resistance
The Sudio A1 Pro earbuds and charging case are sweat and splash resistant, making them suitable for workouts and outdoor activities. However, they are not fully waterproof and should not be submerged in water. Avoid exposing them to excessive moisture or harsh chemicals.

Cleaning
To maintain optimal performance and hygiene, regularly clean your earbuds and charging case. Use a soft, dry, lint-free cloth to wipe the surfaces. For the eartips, remove them from the earbuds and clean with a mild soap solution, then rinse thoroughly and allow to dry completely before reattaching. Do not use abrasive materials or harsh cleaning agents.
Troubleshooting
- No Sound/Poor Sound Quality: Ensure earbuds are charged and properly paired. Check volume levels on both the earbuds and your device. Try re-pairing the earbuds.
- Earbuds Not Pairing: Make sure Bluetooth is enabled on your device and the earbuds are in pairing mode. Turn off and on Bluetooth on your device, then try pairing again.
- Charging Issues: Verify the USB-C cable is securely connected to both the case and the power source. Ensure the charging contacts on the earbuds and inside the case are clean and free of debris.
- Active Noise Cancellation Not Working: Ensure ANC is activated via touch controls. A proper fit of the eartips is essential for effective noise cancellation.
