Some environments (such as airports, offices, crowded public spaces etc.) can interfere with your Bluetooth connection. To optimize your Bluetooth connection:
1) Ensure your phone is on the right-hand side of your body.
2) Download videos and songs instead of streaming.
3) If you have an Android phone, temporarily disable unnecessary app traffic settings on your phone.

Or you can try:
- Resetting the earbuds. See "How do I reset Liberty Air 2 Pro?"
- Try a different device if possible.
