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.

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.

Very helpful in keeping your voice soft and low yet heard by all in the classroom

Thank you perfect. Just what I was looking for.

With the time, i’ll give me problems with the battery

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 used this device as a driver. It worked great first few days, but the charge doesn’t keep like it did. Doesn’t last nearly as long as it did.

Great product used for soccer field when coaching able to project my boys to the entire team while they are in position!
