Showing how to connect the JBL Free in-ear headphones to your smartphone. In case the headphones do not show up in your smartphone, you can try to press the button of the right ear piece for 5 seconds. This forces the headphone into pairing mode. In case you can only hear sound coming out of the right side, then the left side did not successfully connect to the right side. Press the buttons on both ear pieces at the same time for 3 seconds to connect them.
