Despite the fact that this can be an irritating issue, it is usually easily fixable if you follow a few simple troubleshooting steps.

Fix 1: Check the battery life

To begin, check the earbuds’ battery life. In addition to having a battery life of up to 6 hours, the JBL Live 300 TWS earbuds can also be charged in the case. You should make sure that one of the earbuds is fully charged if it is not working. Let it charge again until it reaches 100% if it is not already charged.

Fix 2: Check the connection

Your device should be connected to the earbuds. If the earbuds are fully charged, then check their connection. Your earbuds should be paired with your device correctly and their connection should be strong. You can either re-pair your earbuds by deleting them from your device’s Bluetooth settings and re-pairing them if the connection is weak. If the connection is weak, move your earbuds closer to the device or reset the connection by moving them closer to the device.

Fix 3: Check for firmware updates

Fix 5: Clean the earbuds

There is a possibility that dirt and debris can accumulate inside the earbuds, which may affect their sound quality and connection.
