Mini Megaphone Voice Amplifier — Wired Microphone & Mini Speaker, USB Disk and TF Card Player, Wide Coverage Area

Compact, multifunctional portable loudspeaker combining high-power speaker output with digital music playback. Supports a wired microphone and can play media from a USB disk or TF card, delivering clear, loud sound across a wide coverage area. For best amplification, hold the microphone head about 1cm in front of your mouth and speak directly into it. If you hear howling or feedback, lower the volume and move the unit and the microphone further apart to reduce interference. Recharge the battery after it is used up; if the device will sit unused for an extended period, recharge it once a week.
