Mini Microphone Voice Amplifier Portable Rechargeable Loudspeaker, Teacher Wired voice amplifier with headset, microphone voice amplifier headset for class for elderly

Well you get what you pay for! These were relatively inexpensive and they served the purpose for a marching military style drill team! The style is rather old school but then again I didn't pay a lot for it.

Ha sido muy útil ahora en las clases híbridas. La dificultad que significa hablar con cubrebocas frente a un grupo, ha sido subsanada con el mini amplificador. He considerado seguir usándolo, aún cuando en algún momento ya no sea necesario el uso del cubrebocas, pues ayuda a evitar el desgaste de la voz. Buen volumen, alcance y buena duración de la batería.

can use in a class of 150students

It's small and compact but heavier than expected. Still, it is works well and when I use the supplied strap as a waistband, I don't feel the weight. I crank it to the max and my students can hear me and I found out that the class across the hall can hear me as well. It's great in the gym! Today is my first time using it and I didn't strain my voice at all. The first charge took about 2 instead of 3 hours so I'll see how long it lasts.

Je suis institutrice primaire, j'ai essayé mon amplificateur aujourd'hui.Il fait beaucoup de bruit malgré les précautions prises (téléphone éloigné, outils numériques plus loin).Le micro fait un peu "chip".Cependant, il est très abordable et j'espère qu'il fera le travail pour lequel je l'ai acheté : économiser ma voix et épargner mes nodules.
