Tired of straining your voice in large classrooms or outdoor settings? Our Teacher’s Portable Voice Amplifier delivers louder volume without distortion, ensuring every student hears you clearly—without shouting.
3.5-inch speakers plus a booster circuit assure loud and clear sound, helping students listen clearly and save the teacher's throat.
Working well with minimal feedback with advanced frequency shifting technology. Keep the distance between the voice amplifier and the microphone at more than 20 cm to supress the eEar-Piercing Feedback
The dial control allows for more subtle and precise volume adjustment. When worn on the body, the dial is more convenient for volume adjustment than the button type.
You can adjust the angle of the microphone to position the microphone head as close to your mouth as possible to achieve the best amplification effect.
