Mini Megaphone Voice Amplifier with Wired Microphone - Portable Speaker, Supports USB Disk & TF Card Player, Easy to Operate

Compact, multifunctional portable loudspeaker that combines clear voice amplification with digital music playback. Built with high-power speakers for loud, crisp sound and wide coverage. Includes a wired microphone and supports playback from USB disk and TF card for versatile use. For optimal voice amplification, position the microphone head about 1cm from your mouth and speak directly into it. If you experience howling or feedback, reduce the volume and move the unit and microphone farther apart to avoid interference. Recharge the battery after it has been fully used; if the device will sit unused for an extended period, recharge it once a week.
