## Description

desertcart.com: Norwii Voice Amplifiers for Teacher with Headset Microphone and Speaker | Natural voice amplification preserves the original sound. Free from noise and feedback. Portable design for Indoor use. : Musical Instruments

Review: Great for amplifying voice - 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
Review: Rowdy classroom voice saver - This has been a day saver in my large theater classroom. When it is difficult to bring students back to attention, I put it on at full volume. I have even dropped it several times and it continues working. Well worth it!

### ⭐⭐⭐⭐⭐ Rowdy classroom voice saver

### ⭐⭐⭐⭐ Won't last a year, but it's a great little device!
*by D***R on February 17, 2024*

I'm purchasing my third one in less than three years, using it only during the school year as I am a music teacher. I love that I can wear it like a little purse; I like it in white; it's a voice saver for sure; it's easy to charge and lasts through the whole teaching day; the headset is lightweight. It's really awesome and I don't even want to try a different one. It's not super expensive either. But I'm starting to wonder if it is purposely designed NOT to last so we have to replace it for another $30 each year?
