A full charge for the case takes approximately 1.5 hours. The earbuds provide up to 9 hours of playback, with an additional 16 hours provided by the charging case, totaling 25 hours of battery life.
Maintenance
To ensure the longevity and optimal performance of your earbuds, follow these maintenance guidelines:
- Cleaning: Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth. Do not use harsh chemicals or abrasive materials.
- Ear Tips: Remove and clean the silicone ear tips with water and mild soap if necessary. Ensure they are completely dry before reattaching.
- Charging Contacts: Gently wipe the charging contacts on both the earbuds and inside the case to prevent debris buildup, which can affect charging.
- Storage: When not in use, store the earbuds in their charging case to protect them from dust and damage.
- Water Exposure: While IPX5 rated for water resistance, avoid submerging the earbuds in water or exposing them to high-pressure water jets. Dry them thoroughly if they get wet.
Troubleshooting
If you encounter any issues with your AU-Stream Hybrid earbuds, try the following solutions:
- Earbuds not pairing: Ensure both earbuds are in the charging case, then open the lid to initiate pairing mode. Check your device's Bluetooth settings to ensure it's discoverable and select the earbuds.
- Only one earbud working: Place both earbuds back into the charging case, close the lid, wait a few seconds, then open it again. This often re-syncs the earbuds.
- No sound: Check the volume level on your connected device and on the earbuds. Ensure the earbuds are properly seated in your ears to create a good seal.
- Charging issues: Verify that the USB-C cable is securely connected or that the wireless charging pad is active and correctly positioned. Clean the charging contacts if necessary.
- Touch controls unresponsive: Ensure your fingers are clean and dry. A quick reset by placing the earbuds in the case and closing the lid can sometimes resolve this.
