Portable Mini Voice Amplifier Wired Headset Microphone Speaker Set for Teachers 15W Rechargeable Lightweight Personal Mic for Classroom,Tour Guides,Instructors and Presentation

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.

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.

I like the sound quality, I bought it for use under a mask for students to hear me clearly. It is very powerful though and I need to keep it quiet enough in my room so the entire hallway isn’t listening too - it’s difficult to ‘mark’ the volume knob to know the perfect spot without a second person daily.

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.

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.

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.

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".

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
