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!
Review: Worth it!!! - This is actually an excellent product. I teach horseback riding and needed to save my voice from projecting to riders across an arena all day. I just purchased my second one. The first one lasted just over 2 years of 6 hours a day daily use. In the dirt, rain, and sun. Definitely not ideal conditions for an electronic device but the functionality was great. I was really surprised at the durability. The value for money is totally worth it.

### ⭐⭐⭐⭐⭐ Great purchase
*by S***Y on January 24, 2024*

I have had mine for about a year now. I use it for teaching in the classroom and I appreciate how easily it is to change the volume on it and that it gets loud enough for me to use it in the classroom. It is a little heavier, so I wouldn't recommend using the clip on your waistband unless you have a belt on. It's also really helpful if you're sitting down and can set it on the table if you're reading aloud or standing at a podium. The battery also last for a really long time. I substitute teach, so I'm not working everyday, but I still only have to charge it maybe once a month. The microphone cord sometimes makes a little noise as it's tapping against your clothes or if you bump it while you're talking. The microphone works really well and has a clean sound. It also has good noise canceling and just picks up your voice instead of all the noise around you, whether you're wearing it on your head or around your neck.
