【Voice Amplifier】 - The perfect solution for when you struggle to speak loudly enough, the personal Voice Amplifier is here to save your throat. 【Bluetooth Voice Amplifier】 - Not just an amplifier, this device also doubles as a portable Bluetooth speaker.
Has decent volume. Accepts USB and micro card plus FM can connect to FM headphone or blue tooth. This is my second one after probably 5 years. First one still works but battery doesn't show charged.
