This voice amplifier works well, adding volume and clarity, but I would say it's best suited for outdoor use within 10-15 yards of the people you're talking to. If you need to talk to a much larger group, from further away, you'll need something with more power. But if you are leading an outdoor class, or guiding a small tour, you'll find that it does the trick.Getting the headset/mic on and positioned can be a little tricky. I suggest doing that before turning on the power, otherwise you'll get a lot of handling noise. Once positioned, it's pretty stable, and I experienced little to no feedback, even when I used it at full volume in a smaller, echoey room. That's definitely good.The quality of the sound is fine for bringing more clarity to a speaking voice, but don't mistake this device for a music player. With the FM radio feature, AUX IN and a micro SD (TF) card reader, it CAN play music, but there are a number of bluetooth speakers in the same price range that would perform better for music.

I purchased this mainly to have a low-priced voice amplifier for use in a van and small bus to alert passengers while I’m driving. It works fine for that, and I don’t have to yell or turn around. It was also good for the groups when outside - I held it above my head to reach the ones in the back. It’s not for far distance, and it’s not super loud, but it does what I wanted it to do. For the price it’s fine. Microphone fit is good, and easy knob to tun turn volume up/down..

Working in a school and having to wear a face mask, this voice amplifier really came in handy. As teachers well know, it’s very hard to breathe while projecting your voice clearly to a large group of students. This device saves your voice, allows you to breathe and gets your students’ attention. Well worth the investment, with or without a face mask.

For only $28 this is a great deal. This will be handy for VBS this year outside so the kids can hear me. When I connect my phone through the aux port this thing really puts out the sound. The battery life is excellent, I ran it for 11 hours straight with the radio up pretty loud and it was still going strong. Of course you aren't going to get excellent bass when talking through the speaker using the mic, but it was loud and clear as I tried it out this week. The kids also are loving using it as a karaoke in the living room haha.I posted a video review on YouTube, just look for the channel Garrenteed

The product does ecactly what it says. It amplifies your voice. The speaker is pretty decent for the price and can be used for playing music through an aux cable which is provided. You sound pretty clear through the speaker with the included microphone but wouldn't try using the mic with anything else. For the price if you really need a portable voice amplifier for small venues this works.
