Bluetooth Voice Amplifier for Teachers, Portable Rechargeable Mini Voice Amplifier with Wired Microphone Headset, PA System Megaphone Speaker for Teachers, Singing, Training, Presentation, Tour Guide

This is an amazing product. You can use it just as a mic, a mic and sound. It's easy to use, the battery lasts a long time.

Es compacto, y bastante potente mucho mejor que un megáfono excelente para los maestros fue un regalo para mi madre y le ha sacado un gran provecho

I practice safe masking, and I find that sometimes people cannot hear me well (esp my hard of hearing father.) So I got this to see if it could help me be undestood better, if I am wearing an N95 mask, or any type of mask. and while its a good product, and I like it, unfortunately it did not do well with that. It works very well if its very close to your mouth, almost touching your lips pretty much. but if you have even a thin n95 mask, between you and the device, it leaves it not really picking up your voice, as the extra inch or two of space...and thin layer...is seemingly too much distance for it from the mic. So while under normal circumstances, its a great product, but if you are a mask wearer, (even for Halloween ? ) or whatever....this thing may or may not be able to really help you be heard much, as it needs to be...right up almost touching your lips and mouth to work properly. I will likely find some use for it though, and for most other applications its likely quite good.

Excelente gracias por su servicio

Probably more well suited for a small classroom.

Thank you perfect. Just what I was looking for.

I've tried two other units and they weren't as clear and loud as the Bietrun. Works well blue tooth device but I prefer the corded option as bluetooth can be spotty.

I was in market for researching a quality and portable speaker with microphone. My search is ending with the purchase of this device. This little voice amplifier has a good battery life, louder and clear voice, price wise is affordable, lightweight and compact. The device works pretty well. I would definitely recommend this item.
