Try doing default factory settings. Step 1. Press the "Power" button located on the top center part of your JBL Charge 4 Bluetooth speaker. The speaker will be powered on when the LED backlight under the Power button is lit. Step 2. Hold down the "Bluetooth" and "Volume Up" buttons at the same time for roughly three seconds. The Volume Up button looks like a plus sign. Additionally, it's important to hold down the "Bluetooth" button in the center of the device next to the Power button, as it's easier to hold down. After three seconds, the LED ring around the Power and Bluetooth buttons will briefly light up before the JBL Charge 4 powers down. Step 3. Press the "Power" button again to turn the JBL Charge 4 Bluetooth speaker back on. The Charge 4 will instantly turn on in Discovery mode, with the Bluetooth LED blinking on and off, and the speaker making a pinging sound. This confirms that you've successfully reset your JBL Charge 4 to its default factory settings. You'll need to pair or re-pair any devices you want to play audio through the JBL Charge 4 speakers with the device.
