Portable wireless megaphone and teacher voice amplifier with 5W output. Supports Bluetooth, TF card and U disk connection for flexible playback. High-fidelity speakers and 5W high power deliver loud volume and strong penetration while built-in optimization prevents howling. Equipped with a 2600mAH large battery for long battery life and an intelligent frequency-conversion power amplifier that includes an anti-whistle module and intelligent noise reduction — producing clearer, louder sound with no whistling.

Easy coverage of 1500 with 5W high-power uniform amplification to spread sound widely. REC one-key recording allows you to retrieve the class review at any time; recordings are automatically saved to TF card/child disk. Also functions as a protector in low light with direct lighting for safe night use. Separate acoustic noise reduction microphone design makes it easy to wear.
