ZOWEETEK Voice Amplifier for Teachers, Bluetooth Voice Amplifier Personal Microphone Headset for Speaking, Portable Power amplifiers for Classroom, Coaches, Training, Meeting, Teacher Must Haves

I'm a PE teacher and this cute little amplifier has been a great way to save my voice! It is very loud (adjustable), I can talk in my normal voice and my students on the other side of a pool or gym can totally hear me. The head piece is comfortable and stays on my head well.

This is a very nice portable speaker and microphone. As a person that speaks very low I carry this around regularly and use it for speaking to ensure everyone hears me clearly. It is great for any speaking engagement where you need to be heard. It is very small and easily concealed but packs good volume and crisp audio

Naturally, I am a reasonably loud speaker. In general, I can speak to an audience for a while, and people can hear me just fine. So if I am in a small group of about 15 people, all is good. Usually, there is a sound system if it is a larger group of 50 or more.For me, there is that awkward size of about 20 to 50 people where I have to talk so loud that my voice starts to wear out, and I also feel like I am shouting.This device is going to be handy to keep in my tool chest for situations like this. The sound is good and pretty clear, and it can certainly help with those small—to medium-sized groups that you would be talking to.Don't expect this to fill a gymnasium, but a small to medium-sized room should work well with this. Plus, the battery charges with USB-C, so I don't need any special cables. The battery life also seems quite good and can get me through anything I have needed it for so far.

I sometimes teach in a large computer lab (the largest in the world actually). This helps my voice to carry past the first two rows of pods. It worked so well that another teacher asked me to turn it down. It's light and easy to carry. Easy to turn on and adjust without looking. I have even begun to use any of the advanced features.

I think this is the next best thing to a megaphone. It was easy to use and carry around. The battery life is great. People can hear me loud and clear from the back of a large room.

This is a portable speaker that comes with a headset microphone and can connect to mobile devices via Bluetooth. It's lightweight and can clip on your belt, or you can use the provided strap. It charges via a supplied AC charger. Its intended use is for speaking to small groups, lecturing, meetings. It also can be used as a player speaker for mobile devices, as there is a place to plug in external portable drives so you can play music from them or via bluetooth using its supplied forward, back and play controls. I found the sound to be a good volume but somewhat tinny, and there is only a volume control, no tone control, so you cannot alter the tone. This is sufficient for talking to small groups, but I wouldn't recommend it if you need high fidelity.

The media could not be loaded. This is a good public address system for educators, especially when teaching outside, someplace noisy, or to large crowds of older people. The amplification is quite powerful without too much distortion at the loudest setting. One does have to get the microphone placement in front and close to the mouth just right for best results. The microphone's wire connecting it to the head brace is strong and holds whatever position into which you bend it, so keeping the mic in the proper spot is easy.This unit is somewhat misleading as the microphone is wired to the amplifier box rather than connecting via Bluetooth. The BT aspect is out from the speaker, meaning it can transmit to other BT speakers. One could purchase a BT lapel mic that transmits to a receiver which has a standard audio plug which could be then plugged into the speaker. An example of this sort of BT lapel mic is https://www.amazon.com/gp/product/B0D5CV73CGIt has a slot for a TF card which you can pre-load with audio files to be played from this speaker, but I'm not sure what's the purpose of this feature. It would be much better if you could use the TF card to record what you are saying, but that's not the case with this, at least to my knowledge.The overall quality is so-so. The device is under $30 and definitely feels cheap. Don't drop it or wear it out in the rain. If you treat it right it shouldn't spontaneously self destruct.

Nice personal PA system. Not too loud, but works well in a classroom setting.
