I bought this to use with small groups, but when my colleague, a 5th grade teacher, lost her voice due to illness, I lent it to her. It allowed her to project her voice without too much strain, and the students listened more attentively because they could hear her clearly. The sound was fairly natural without too much distortion. Volume isn’t too intense, but effective for a class of 35. (This assumes it is the kind of class that will quiet down eventually after some correction). Students reported that they could hear the teacher well (and I could hear her fine also on either side of the class). For the teacher, the effect is subtle as the voice is projecting away from you, so it helped that she got feedback from the class that the volume was reaching everyone. For a very large and inattentive outdoor PE class I would not recommend it. But for small groups and manageable classes, it works well. I don’t have experience with the battery life yet, except that it did last her a day and a half of teaching without any report of issues. If you are a teacher who often has vocal strain, or has a quiet voice, this can be helpful. Just mind which way your mic is facing relative to the speaker. She almost quit using it after having feedback problems, as she wasn’t familiar with how sound systems work. Once she knew the speaker needed to be in front of the mic, she had no further problems. While working at her desk, she found it comfortable to rest the speaker on the desk, when seated. It also worked well for walking around the classroom clipped to her belt. For mic placement, I gave her the recommendation from another review here- wear the headband behind the neck and angle the mic up toward the mouth. This seemed a comfortable way to use it without head pressure. All in all, assuming this lasts at least one year, it would be well worth it for my purposes. P.S. I got the rose gold so that it would stand out from all the black technology at my school. As a roaming teacher, I need things to be easy to find when I inevitably misplace them when traveling from location to location.

Perfect for what I needed. Light, good amplification, lasts a couple of hours on a charge. Happy.

This is the 2nd one of these I purchased, and I'm still waiting to use it. The first one I purchased, after about a year's use, started to get some static when the cord was even slightly touched. I was careful not to aim the microphone toward the amplifier, but this would still happen. So, as far as build quality/durability, it's decent for the price. It was worth purchasing again, as it saved my voice. It's easy to use and does a great job projecting sound.

This thing is absolutely amazing! I do a lot of speaking at schools, and sometimes they don’t have a PA system. That’s when this comes in. Even in a big gymnasium, it’s really good sound quality and an amplify my voice really well. I’m actually really impressed with the microphone quality. It’s lightweight and clips to your pocket or the top of your pants. And it stays charged a really long time. I highly recommend it.

I am a teacher and I don't have a strong voice that projects well, so this worked really well for me. This is not going to give you the volume or sound quality that a profession speaker in an auditorium would need. It suits my needs though. I teach approximately 32 students at a time and it's basically impossible to get them to all stop talking. When I try to raise my voice I just sound shrill and like I'm always yelling at them. So I tried this little voice amplifier and I've been very happy. I can speak in a calm voice and still be heard over the ambient noise. I generally leave the volume all the way up and vary how loud my voice is by how close I put my mouth to the microphone. If I need to be loud, I dip my chin to speak directly into the microphone. When I need to have a private whispered conversation with a student, I raise my chin and don't speak into the microphone. It's become second nature. I wear the headset around my neck and put the microphone in my pocket. I do have to wear pants with large pockets to make this work, so it has limited my wardrobe. The little belt loop clip on the speaker is pathetic and doesn't stay in place, so if you can't put it in your pocket I don't think you will be happy with this system. It's really my only complaint. As far as feedback, when I sit down with the volume turned all the way up, sometimes I'll get feedback. So I generally turn the volume down to halfway before I sit. Since I rarely sit down with kids in the classroom, it's not really a problem and I never get feedback any other time. Overall, I love this cheap little voice amplifier and I wonder how I ever taught without it in the past. Of course a wireless system with higher quality speakers would be better, but this was simple and affordable. You don't need to have any expertise with technology to make this work. Highly recommended!

Apio para clases con el regreso a la presencialidad

Been using it when I’m teaching. Helps to save my voice & am audible even with my mask on. Good buy!

Excelente produto!

I am able to teach six hours straight without losing my voice due to this amplifier. It is loud enough for large university classrooms and auditoriums. Works flawlessley and offers the best value for the dollars spent. Feedback Problem and Workaround: It will squeak at a loud volume due to feedback. However, I solve that problem by clipping it on my waist belt towards my back. That directional disparity resolves the feedback problem. In this configuration, it does not squeal even at the full volume. Background: If you are in public speaking business, you know the importance of a reliable technology including PPT projection and audio. I teach at a large public university where all the fancy tech from inbuilt audio system and bluetooth microphone to podium microphone are available. However, there are always connectivity issues before each lecture. You know that universities' admin staff do not like to work. Particularly tech-support are the most useless people on earth. They spend 10 minutes generating a ticket before sending help. 15 minutes of tech support for every 90 minutes lecture is a nonsense. Hence, I bought freedom in the form of this amplifier and I am very pleased with my purchase.
