Muy bueno

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.

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!

There's a lot of static feedback if it gets too close to certain things. It's ok for what I needed it for, but have to be careful how you handle it.

No lie, my wife lost use of her voice to just a whisper while surviving lung transplantation. Being heard when you are that vulnerable is important, and this little thing did the trick for many weeks.
