Great sound and capabilities
Very pleased with all of the possible amplification options. Bluetooth paired easily with phone and computer - good range, tried it between rooms, perhaps 30 feet. When I cycled inputs on amp, it quickly reconnected automatically to phone. Mic/headset and all features listed work well. Operation is simple - a single button cycles through different inputs. I am impressed with the FM receiver - as good or better than some of my other small portable radios. Any use of a mic and amp can cause feedback - so start with low volume and position amp and mic for best results, slowly raise volume to suit needs.

Works great for school
As an elementary school librarian who teachers lessons to every class in the school, every week, having to wear a mask, I was concerned about my voice. I purchased this at the beginning of the school year and have used it for six months now. It stays charged for around a week or so. It allows the students to hear me clearly and I can hear myself so I do not strain my voice even when I have two masks on. Once you get over the feeling of working in a theme park, it is truly helpful! Many of the other teachers in my building have bought them as well.

Perfect for teaching but gives a lot of feedback.

Game Changer
This product was purchased to boost my voice over my mask and across my classroom as we are all social distanced from one another. This little device is fantastic. It is easy to wear, light to carry, easy on /off switch. The "how to" directions are not the best but it is simple enough to figure out. Battery life last 3+ hours. I give it a quick boost 30 minutes it lasts all afternoon (I do not know the duration of the battery life). The students noticed right way I was easier to hear. I LOVE this little device.

Works Perfect for This Teacher
This is amazing! I teach elementary. With COVID guidelines in place, my 32 students have a hard time hearing me through my mask, the constant running of the AC, the windows and doors open, and two air purifiers. I slide this little microphone behind my mask, and viola! They can hear me. It’s great for outdoor use during my recess and PE duties! I HIGHLY recommend. Only downside is that it’s USB charged.

Saved my voice and my job
I've used a portable speaker/mic daily for the last 5 years. This one is awesome, lightweight, great quality, and inexpensive. This has saved my job. I'm a teacher and without it, couldn't last a week without losing my voice. Whenever I see people straining their voices to project to a large crowd, I just want to give them "my little buddy".

Muffled sound and horrible feedback
Sound is muffled and you have to keep the microphone an uncomfortable distance from the headset or you get horrible feedback. If I buy again, I would pay more for a better quality product.

It does work for my wife who is teacher and was tired of shouting through her mask
It's nice to have a system like this where you carry the speaker around. It's light fits on belt with no issue. Charge is good for day of teaching. An advantage of this, compared to a wireless solution with a fixed speaker, is if you are walking around in the room with a fixed speaker you easily end up getting those piercing feedback screeches if your mic and speaker line up. That being said it would have been really nice if they had added some anti feedback electronics to this. If for instance you tilt the speaker up to look at it, you'll get the feedback (technically you don't have to the controls are on the top, still my wife kept wanting to lift it to look at it when she first tried it) She also had a problem when she was reading from a book in class, apparently there was enough sound reflection off the book to get the feedback going. Anyway as proof of concept this thing does work. I would recommend looking for something that additionally has some anti feedback electronics built into it

The quality is much more than I expected! It is very clear, no static and adjusting the volume is very convenient. Definitely worth the purchase

Pode comprar sem medo. Dou aulas para o ensino fundamental 8 aulas por dia e atende muito bem para 40 alunos. A altura é muito boa, a voz sai limpa e a microfonia quase não tem , só não pode apontar o microfone diretamente pra caixa. Todos os alunos conseguem ouvir com nitidez . Estava precisando pois não tenho a voz alta, só consigo dar aula com esses microfones. Superou as expectativas. Melhor amplificador !!! Impressionado ainda com a qualidade. Observação: O conector não é tipo C , mas nada demais para o propósito que cumpre
