Review: Great sound quality and volume, long battery life! - I teach workshops inside loud venues, like breweries, and I wasn't sure if this would be loud enough for what I needed, but it has worked great! Even with a group of 30 or more people in a large outdoor space, everyone can hear me well. I used it for at least 5 classes (2 hrs per class) and the battery still didn't need to be charged. Worth every penny, and I wish I'd bought it sooner!

### ⭐⭐⭐⭐ Works too Well
*by S***D on March 19, 2026*

It's really a nice item, however it doesn't really work for outside use. It doesn't filter out the wind noise.
