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.

To connect a Charge 3 and a Flip 4, you will need to follow these steps:

1. Make sure that both the Charge 3 and the Flip 4 are turned off.
2. Connect the Charge 3 to a power source using the supplied micro-USB cable.
3. Press and hold the Bluetooth button on the Flip 4 for 5 seconds until the LED starts flashing blue.
4. On the Charge 3, press and hold the volume down and play/pause buttons simultaneously for 5 seconds until the LED starts flashing white.
5. On your phone or other device, go to the Bluetooth settings and look for the Flip 4 in the list of available devices.
6. Select the Flip 4 and follow the prompts to pair the two devices.
7. Once the Charge 3 and the Flip 4 are paired, the LED on the Flip 4 will stop flashing and remain solid blue.

I hope this helps! If you have any further questions or if you are having trouble connecting the Charge 3 and the Flip 4, don't hesitate to ask.

This usually happens when your speakers has hidden feature, try to look for for appear option. When trying the next time make sure that your paired device is not connected to it, as most probably it can not connect to two devices at time.

Are they connected or paired now? Make sure you don't have any other device near that may have Bluetooth on. Like a laptop, PC,or tablet. Try forgetting the device, and reconnecting. If this fails make sure your phone isn't on wifi and cellular. If this all fails. I imagine its not the fault of your transmitter, but lies in the fault of your reciever, the JBL flip. Also, is it fully charged and is the speaker holding a charge? I'm a small Bluetooth speaker junkie, and I'm sorry but I am not impressed with these at all. There are much cheaper, and better made out there, than this one.

Put JBL Charge in pairing mode: turn on Charge. Hold down power button till it flashes red and blue. You're in pairing mode. Go to your device and find Charge and pair up. Done!

This indicates that the Blue tooth pairing with the already paired device has been reset and the JBL Flip is ready for pairing with new device. This position, red and blue blinking, can be obtained by long pressing the power buton.

Press and hold power button while trying to connect to new device to reset conmection
