Voice Amplifier -- Protect Your Voice Effectively

Voice Amplifier is a lightweight, wearable voice amplifier designed for educators and public speakers who need clear, room-filling sound without straining their vocal cords. 

Featuring advanced anti-howling circuitry, all-day battery life, and versatile playback options (Bluetooth, USB, TF card, AUX Input, FM radio, recording), it covers classrooms and event spaces of up to 200 people — all in a compact, under-one-pound package.

Key Features

4. Audio Playback Resume — Automatically remembers your last playback position when switching modes or powering off, so you never lose your place in a track or recording.
