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!

powerful amplifier for street preaching
This is a powerful amplifier for street preaching at a park or on a street corner. I love the quality of sound and design. The hands free headset allows me to hold up my signs while preaching to passersby. It also records and plays music. I definitely recommend this voice amplifier to any one looking to get into street preaching and amplification is needed where people gather.

Lightweight microphone
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.

Best choice overall
I bought this in August 2022. It is currently April 2024. It still works exactly the same as when I bought it. However, the microphone foam piece is falling apart. The sound actually feels like your voice and not altered. It gets VERY loud which is amazing for this teacher! But, it can also be really quiet too if you lower the volume. I use it every day in the classroom and on field trips. The battery life feels a little scary at first because it seems to drop very quickly, but it usually holds in the 40-50% range for quite a while before dropping again. If I start with 100% battery and use it for 4-5 hours, I'll have at least 50% or more battery by the end of the day. Best money I've ever spent.

Very bad rechargeable battery
Not even a month went by when the battery wouldn't hold its charge. The most it would get to was 70 but when you turned it on it would drop right away to 10. Very disappointed. I would not recommend this product

Great purchase
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.
