This worked great. I have to use it for outdoor meetings. Charge holds for a bit and it’s easy to use. It isn’t bulky at all. Beware of the feedback when they speaker is too close to the microphone.

A small, portable, hands-free amplifier that packs a huge punch. I purchased this for presentations, and the audience had no problem hearing every word.

I used this to mic my young performers onstage. I've used several different kinds. this works well and only had one drawback. When you turn it on, it makes a loud noise to let you know it is on, unless the volume is already turned all the way down. Not a big deal if you are using it for a class or speech. It's kind of a big deal if you have 15 kids wearing them and turning them on and off as they enter and exit the stage. Overall, a really good product. However, I will not buy again because I need the power on process to be silent.

Light weight and works great

It worked, but there was a high level of static. Also, the headset died not comfortably fit

Works really well for my already too loud daughter. Not very well built would easily break if dropped

Works well ! I use it for an exercise class at a senior center .
