Norwii Bluetooth Voice Amplifier, Power Amplifiers, Portable Mini Wired Microphone Headset for Teacher Classroom & Outdoor Lectures, Teaching, Tour Guides, USB-C Rechargeable - 4000mAh, Black

Works perfectly. I has helped with my student to make them listen and pay better attention. Good battery and volume

Update! I just bought a second one. The design is slightly updated. Works like a charm. Hoping to get 2 more years out of it! I bought a different one recently, and that broke after 2 months (the strap broke the first week. Not this product! I'm coming here to give this item 5 stars. Will update with how long it lasts me this time around! This cute little mic lasted me 2 years of continuous teacher use before glitching in me. So sad. I loved it.

Due to a medical condition in need a microphone for work. It works well and is pretty loud for a classroom. I would prefer a lapel mic, but the furnish mic works fine for classroom use.

It is a great mobile personal amplifier that helps me speak audible to the students. The sound is clear and the system has long our battery.

The sound amplifiers are very good and easy to use . It was a bit strange not to be able to put it on the head but only around the neck, but I like it. They won't fall off like this. Thank you .

I am very soft spoken, so when I teach or give presentations, it is difficult for me to project my voice to a large crows for extended periods of time. (Sore throat after speaking more than 10 minutes loudly). So this device allows me to speak in a normal voice and just increase the volume. It is sensitive so when walking around if you bump the mic it pics up every sound and getting the mic close will make the screeching sound. It was also comfortable to wear for extended periods of time. The battery lasted hours. The sound quality isn't amazing, but people can hear you clearly. When i say it isn't amazing i mean that it doesn't have a lot of bass, so your voice doesn't sound as "full" but it can be heard clearly

The sound Is a good sound, it’s not super loud, but it was good enough for a small dance lesson. Good size but not heavy for a speaker. I got pink for her because of the color looks good.

After using only a few days the microphone no longer worked. Could not get replacement or assistance with unit after many tries. Have Dysphonia and need voice assistance. Sadly a loser!!!
