Works great!
I used this for socially distanced, masked rehearsals In a park. Our first attempt, before the mic arrived, was torturous. With masks and distance and ambient noise, it was exhausting to get attention, be heard, or be understood.This. Unit made it possible to do the work while maintaining safe distance. I wore the mic inside my mask. The sound quality is excellent. The controls on the wireless earpiece made it easy to mute or adjust volume when necessary. I didn’t play with the controls on the speaker much in rehearsal, but I was able to pair other devices via Bluetooth to play some musical examples. There is the option to wear the speaker unit or set it somewhere. I was working in a 50 sq. yd. space and never went out of range. The speaker fit in my overall or cargo pants pockets when I was moving around. This helped my singers/actors to locate me instead of just my voice coming out of a remote speaker on the sidelines. The speaker, like any speaker, needs to be pointing toward the listeners, especially in an open air setting. Battery life was excellent.

Adds good/easy reverb
I use a lapel mic with my NAF and this amp with the echo turned on when I want some reverb. It works really well, is portable, and easy to use.

Not a bad little unit, don't let its size fool you
I use it in a moving train car. I sing tunes and use the uhf wireless mic with the unit. I accompany myself with a banjo, which is acoustic. I have the 18 w model but thought I'd try this because it had 25 w. I like the placement of the volume knob, the echo effect feature can only be added slightly without sounding horrible. I've used it all day without a recharge, it's a shame there's no way to tell how low it's getting, the 18 w has a digital readout of the charge that is remaining. I left the headphones power on during a break and it ran out on me, but the headphones charge up fairly fast. The 18 w is a warmer sound quality, but I find myself using the 25 w as first choice, mostly for the volume knob convenience. I prefer the casing of the 18w because I know I'm going to scratch up the the shiny casing of the 25w, but it looks nice now, I've used it for four days. (Starting fresh charge each day)

Only worked 1 time!
Very disappointed. We got this to use in a resthome setting. The first time it did fine and we were pleased with the result, the next time, there was no response. The unit was completely dead. We charged it but it did not charge. The unit is completely unresponsive. We have not dropped it or had it any where near water. It has been kept safe and secure and yet there is no life in it at all. It does not even charge.

Great for teachers in classroom or cafeteria
I loved the quality of the voice amplifier and the wireless headset is super user friendly. The battery life was great for a full day of teaching and reduces the strain possible with teaching all day. USB charging cable was super easy to use too. The volume level is is easy to adjust to the size of the room from the headset and from the speaker itself. This has been a tremendous asset in my classroom.

Decent but unspectacular product.
This is a fine product - not great. Not that powerful for outside. But it is easy to use and holds a charge pretty well. I would say it is ok to use inside in a modest side room, and unless you have a very small crowed outside, I would go with a different product.

Worked great!
I used this for an outdoor gathering by a busy city street. There were about a half dozen who shared and we handed the mic around with no problems for anyone. I also used it for prerecorded music to introduce the event. Everyone was impressed with the quality in such compact size.

The sound quality is fantastic!
I use this amp to sing. I'm a professional musician. I play at different nursing homes and assisted living facilities. The sound is extremely good for the size of the unit and it is very easy to control. The unit itself has a pretty long battery life, but the mic has to be charged each time I play. Not a problem for me, since I'd rather do that than fight with a cord on a corded mic or amp.

Le produit est conforme à mes attentes et aux descriptions données. Nous l'avons essayé dans une salle des fêtes volumineuse et le résultat est parfait.

Il prodotto funziona abbastanza bene all'inizio ma dopo qualche mese la batteria inizia a durare pochissimo e la cassa non funziona mentre è in carica, in pratica diventa quasi inutilizzabile.

Buen sonido y calidad de voz. Una herramienta muy buena para profesores/as que suelen tener problemas en la voz.

I’m a riding instructor and needed something to amplify my voice. Teaching up to 8 lessons a day it sure saved my voice. Used in a large indoor arena and it carried my voice throughout. So not only my student could hear me loud and clear but the other riders as well and they stayed well out of our way. Still have battery power.. I put speaker on jump standard only lost me a couple of times when I wandered to far away. Stayed connected within 30 m. . Would automatically connect again when In range. Can’t wait until it warms up enough to teach outside.
