Some environments (such as airports, offices, crowded public spaces etc.) can interfere with your Bluetooth connection. To optimize your Bluetooth connection: 1) Ensure that your phone is on the right hand side. 2) Download videos and songs instead of streaming. 3) If you have an Android phone, temporarily disable unnecessary app traffic settings on your phone. 4) Turn off LDAC on the soundcore App. Or you can try: - Resetting the earbuds. See "How do I reset Liberty 2 Pro Upgraded Version". - Try a different device if possible.
