Please try the following steps :
1. Reset the earbuds. See "How do I reset Life Note?".
2. While the range of most Bluetooth devices is 33 feet (10 meters), the optimal range for any Bluetooth audio device is about 2 feet (60 centimeters) from the audio source.
3. Some environments (such as airports, offices, crowded public spaces etc.), other Bluetooth connections, and Wi-Fi can interfere with your Bluetooth connection. Optimizing your Bluetooth connection:
- If you are in a busy place, ensure your phone is on your right side when using Life Note.
- Download videos and songs instead of streaming.
- If you have an Android phone, temporarily disable unnecessary apps running in the background.
- Stay away from Wi-Fi transmitters.
