Wired High-Power Voice Amplifier Speaker for Teaching & Tours — Portable Microphone Loudspeaker, Easy to Operate

Compact wired voice amplifier with high-power speakers designed for clear, loud sound and broad coverage—ideal for teaching, tour guiding, and public speaking. This multifunctional portable loudspeaker offers sound-amplifying capability plus a digital music playing function. For best pickup, hold the microphone head approximately 1cm from your mouth and speak directly into it. If you experience howling or feedback, lower the volume and increase the distance between the unit and the microphone to reduce interference. Battery care: recharge the battery after it has been fully used; if the device will sit unused for an extended time, charge it once a week to maintain battery health.
