Using this Meyer Sound MM - 4XP loudspeaker is easy. First, connect it to your audio source, like a music player or a phone. Since it doesn't have a power supply, you'll need to use your own compatible power source. When you turn it on, adjust the volume and other settings as you like. For storage, keep it in a dry and cool place to avoid damage. Make sure to clean it regularly with a soft, dry cloth. And always handle it gently to prevent any physical damage to the speaker components.
