Mini Wired Megaphone Voice Amplifier — Portable U Disk/TF, LED Mic Booster Loudspeaker for Teaching, Tour Guide & Promotion, Easy to Operate

This compact, wired megaphone uses a high-power speaker to produce clear, loud audio with a wide transmission range—perfect for teaching, tour guiding and promotional events. For optimal amplification, position the microphone head approximately 1cm in front of your mouth and speak directly into it. If you encounter howling or feedback, reduce the volume and increase the distance between the unit and the microphone to prevent interference. The amplifier supports U Disk and TF playback and includes an LED indicator. Recharge the battery after it is fully drained; if the device will be unused for a long period, charge it once a week. The default color is black; red and blue options are available—please contact us if you need a different color.
