how to fix problem with other people connecting to my speaker

Asked by: kgame
thanks for bringing this to our attention. We understand that you want your speakers fixed so that you can enjoy music by yourself. For now, there is no available feature to put a password on your JBL Boombox 3. What we can suggest is resetting the speaker to factory default settings. In power ON mode press and hold the "Volume +" and "Play" buttons at the same time for more than 3 seconds reset the speaker.
