SHIDUVoice Amplifier, 10W Speaker with UHF Wireless Microphone Headset, Portable Mini PA System 1800mAh Rechargeable Battery for Teacher, Tour Guides, Training, Meeting

Before this I had one that the headset was connected to the amplifier. It was so annoying because the amplifier would constantly fall and eventually it stopped working. I wanted a wireless one but I did not want to pay a lot. This works well for my classroom I love that I can leave the amplifier at the front of my room and be working in a small group and the rest of my class still be able to hear me. Sometimes the sound will go on and out so that is why I gave it 4 stars. The volume is loud enough for a classroom full of first graders to hear me. There is not much static sound, only when the battery starts to go low then it cuts in and out and gets some static. I feel like the battery does last a while I do charge it everyday, because I use it for the whole school day.

The product is very good. The sound quality is good. It is a bit sensitive when I walk past the speaker, and it gives off a shrill, loud screech. It is made for large heads. The headsetʻs band is large, so it doesn't fit well around the back of my head. The weight of the wireless receiver causes my ear to bend down, so the headset eventually falls off my ear.

Too quiet for large group exercise classes. Someone even asked me if it was turned on. It was at full volume and my mouth was nearly touching the microphone. I returned and bought a wired one that was half the cost and it is twice as loud.

I am an elementary teacher and purchased the speaker around four weeks ago. I bought it because I have to use a mask all the time and wanted to help my students to hear me clearly. I have been gently using it for my classes. It worked well during this time, the volume and battery life were adequate and functioned for the purpose, but all of a sudden and for not reason it stopped working. I have tried different things but it doesn’t work anymore. I am very disappointed and need my money back.

This head set Works great when teaching from behind barriers. Since returning to the class room after the covid lockdown I am required to teach from behind a plexi barrier combined with also having to wear a mask. This combo muffles my voice and makes it hard for my students to hear me at a normal tone of voice. I teach math and lectures are 35-45 min long with Q&A for 10-15min 5 times a day - That ends up being a lot of talking at a high volume so I can be heard and was leaving me with a sore throat & mild headache by the end of the day. This amplifier works great. I am able to hook it to the out side of my plexi barrier and the headset is bluetooth which is great for being able to get up and move around the classroom without having to have the speaker attached to me. It is loud with good sound quality - no scratching or distortion. It is USB-C charged which is great - I use it for 3 periods (about 2.5 hours) then charge it up a bit during lunch and it lasts the next 2 periods (1.5-2hrs) no problem. I have not had it run out on me yet. It really does work great - good sound quality and amplification.
