This video explains how to unpair the JBL Clip 4 portable Bluetooth speaker from all devices, that it has previously been paired with.
The process is called a factory reset.
Press and hold the Vol+ and the Bluetooth button at the same time for about 10 seconds until the speaker turns itself off.
When turning the speaker back on, it will immediately enable the Bluetooth pairing mode. That indicates that the factory reset was successful.
