How to Reset JBL Flip 5: Step by Step
Resetting erases any earlier paired Bluetooth devices from its memory. Clearing these stops it from pairing to any nearby BT devices afterwards. Also, you might reset the 5 to get it ready for sale or re gifting. Or reset to stop it from pairing with devices you no longer wish it to pair with.
1. Turn on the JBL Flip 5
Press and hold the Power button until it lights up.

Find the Power button, as we see in the last picture above.
Then, the Power button lights up along with the battery power scale, as we show next. Here, since we’ve paired the 5 with Bluetooth devices before this, it does not enter Bluetooth discovery mode. We know that because the Power button is glows solid gray, rather than blinking blue.

2. Wait for the Power Up Sound
The speaker makes a rising rock guitar strum sound when it powers up. This Flip is ready for use after this sound finishes.
3. Press the Volume UP and Play-Pause Buttons Together
See the next picture to find the Play-Pause and UP Volume buttons.

The speaker then enters reset, as shown in the next picture. Note that both the Bluetooth and Power buttons light up gray white for a couple seconds. Shown next.

Then after a short pause, the 5 turns off. All the lights go off, and it makes the power-down guitar sound.
4. Check that Reset Did Work
Next, power on the unit again, as described in step 1 above.
Now this time, after reset, our speaker comes up in Bluetooth discovery mode, as shown next. Note that the Bluetooth button blinks white to denote this. When the Bluetooth button blinks, this means that the Flip 5 is has no current pairing. Indeed, we expect it not to pair to anything after a reset.

5. Done with How to Reset JBL Flip 5 !
Resetting is now complete. You may now pack up the 5 for sale, or pair it again with your favorite BT devices. The unit will no longer automatically connect with any previously paired Bluetooth device that is in range. To restore automatic Bluetooth pairing, manually pair the Flip 5 with a tablet or phone. Then, any time that both speaker and that device have Bluetooth turned on, pairing with automatically take place once more.
