Review: You will be heard! - I been using this voice amplifier and it’s stops me losing my voice during some of my event/production jobs I manage. The sound for the speaker is clear and loud enough to reach everyone in the room without any distortion and witbout me having to yell or lose my voice. It’s extrmely lightweight and easy to wear, so I can move around freely while speaking. The bluetooth feature is awesome because I can also connect it to my phone to use it hands free. The battery life is also pretty good I’ve used it for hours without needing to recharge and for those long days working its definitely a good thing. The thing I like the most is that it is super easy to set up, so I don’t have to mess with complicated settings before I start using it. If you do a lot of presentations or manage people and need to give direction to a lot of people at once, this thing makes a huge difference in getting your voice heard effortlessly!

### ⭐⭐⭐⭐⭐ Lightweight microphone
*by N***A on June 9, 2025*

I teach Sunday school and used this to work with kids on the playground to play some games. It worked great . The kids and parents to could hear me out well. There is a loud background screeching noise which comes every once in a while suddenly , which u can remove either by adjusting the mic distance from speaker or tweaking the volume. But overall happy with the purchase I love it that i can use it as a Bluetooth speaker- though the connection is a bit time consuming and an emergency power bank. I just wish the controls were a bit more user friendly.
