Save your voice!!
This microphone did exactly what it needed to. I love how I don’t have to strain my voice during the day. The clip makes it easy so I don’t have to walk around with it in my hands or a headset. The microphone quality is nice and clear, as well as the speaker. There is a slight echo but it’s barely noticeable. I kept the speaker on my desk but if it was clipped onto my belt, it wouldn’t have been too heavy. The only thing I would change is the battery life of the receiver. It does seem to die a little faster than the speaker which can become inconvenient to charge midday. Otherwise, great product. Save your voice fellow educators!

Good, but not what it read to be.
While the product is a great with a wired connection, the wireless transmission is super sensitive and causes feedback if place near the mic thus the strap for the body and clip is not needed. Best if speaker is placed across the room. While the sound is amplified, there resonance is tingy or "canned". Wireless mic and transmitter only last a few hours if you plan to use all day. I am a music teacher who is trying to save my voice. While the product does help, the students often laugh at how the sound is not clear. Decent for price range I suppose.

Low battery
I got this product for my classroom as a way to teach and be effectively heard by my students. The sound from the speaker echoes quite a lot. I was also disappointed that all three pieces need to be charged and there was no information on how long the battery lasted for each piece. I would often be speaking and one piece would just shut off without warning. Not a horrible product, but not the best.

Awful feedback
Product Review: Voice Amplifier for Classroom Use I recently purchased this voice amplifier for my classroom, hoping it would help me communicate better with my students. Unfortunately, my experience was far from positive. Right out of the box, I tested it and was met with constant feedback and loud screeching noises from the microphone. The sound was so piercing that it rang in my ears, making it unbearable to use. To make matters worse, I have dogs at home, and the loud feedback seemed to agitate them as well, which added to the chaos during my testing. I was really disappointed with the performance and immediately returned the product. I believe there are better options available, and I plan to explore those. If anyone has recommendations for a reliable voice amplifier for classroom use, I would greatly appreciate your suggestions. This particular product is not worth the investment.

Receiver doesn’t stay charged after very little use.
It’s frustrating. The receiver does not stay charged long at all. I charged last night. Nothing this morning. I’ve used for a couple weeks on and off. The speaker and microphone seem good but the receiver gives nothing. I plugged back in for two hours now again nothing. I plug and unplug and it’s frustrating. I teach and have vocal cord issues. This is another disappointment. I need something that can give me at least three hours of charge a day.

Great Headset
I've been looking for a headset for my mom who speaks very quiet, almost in a whisper. I figured I'd give this item a try since the reviews were pretty good. After charging the headset and showing her how to use it, I can say it works great for the money. It's nice to not have to strain my ears to hear her. You definitely have to keep it charged but it does a good job.

Loud and fun to use!
I loved using it in my class. Especially because it was huge. Great sound quality and battery life. Not too heavy or anything. I’d often throw it in my sweater pockets and forget it was there.

La función inalámbrica deja mucho que desear
El micro de diadema no está mal pero la función inalámbrica, que es el motivo por el que lo compré, es nefasta. No se escucha nada, solo interferencias y pitidos, da igual la distancia.

Lousy voice amplifier
Bought this for my presentation. Participants feedback that the sound is breaking and lagging. They rather I present without the amplifier. I wish to refund as I feel this is totally useless to me.
