My prayers have been answered.
I can't praise this amplifier enough. In 2015 I had cancer of the larynx and went through 6.5 weeks radiotherapy. I count myself extremely fortunate that I didn't have the larynx removed leaving me unable to talk at all but my larynx has gone through a lot, leaving my voice very variable. Sometimes gruff and growling, sometimes barely audible and a great deal of effort and strain is required to vocalise at all. At long last I have seen a speech therapist, who has given me voice exercises and techniques, but also suggested getting an amplifier. I am a carer and see a lot of people who are hard of hearing. Repeating myself has taken its toll on my voice. I bought this amplifier, it is really easy to use. I can adjust the volume to suit the clients hearing ability and my own voice is "cleaned up". The amplifier seems to smooth out my voice getting rid of the growling, gravely sound. My voice is much clearer and I no long have to strain to be heard or repeat myself over and over again. How I wish I had known about this all those years ago, but hey I'm not complaining, I've found the answer now. Highly recommended!!!!!!!!!

Very useful gadget for teaching
I bought this to help me teach language in classroom , this Voice Amplifier is quite small , and very easy to use , ideal for a large class / meeting room, save me to shout and improve the teaching quality. Totally worth the money.

Acceptable
I've been using it for 2 years, and it's good news that it's still working. The negative part is that the sound quality when speaking into the microphone can be improved, some people find it hard to understand me when I speak into the microphone.

Compact
A compact amp with strong reproduction qualities. As described by my sister. I have throat cancer, the amp didn't suit my situation, which is a bummer because it's a great little product.

Loved this little baby
Perfect, lovely bright red colour, good design, not too boxy, works well for my purposes (busking). Couldn't ask for a better birthday present.

Piccolo ma potente!
Le dimensioni dell'amplificatore sono davvero contenute, non me lo aspettavo così compatto, ma nonostante ciò l'audio è abbastanza alto, non è ovviamente paragonabile ad un megafono (ne è il suo scopo) ma si riesce a farsi capire nella folla anche con un rumore di fondo moderatamente alto. Per quanto riguarda la qualità è ottima per quanto riguarda l'amplificazione della voce, discreta per radio e BT, dopotutto non è una cassa pensata per questo. La radio prende bene anche in casa su tutte le principali stazioni e ha dei preset già impostati su delle frequenze e ha il riconoscimento automatico della frequenza della stazione. C'è la possibilità di inserire una microSD, cosi da poter registrare un messaggio (o riprodurre uno già registrato) a loop, o per riprodurre semplicemente musica senza usare il cellulare. Il microfono ad archetto è davvero economico, avrei apprezzato qualche cm in più per il filo che arriva giusto se si tiene la cassa attaccata alla cintura tramite la clio in dotazione ( si può anche appendere al collo tramite un laccio in confezione), ma alla fine fa bene il suo lavoro, ne presenta fruscii o rumori di fondo durante l'uso, nella scatola c'è un filtro antivento di ricambio. Se usato al massimo la batteria non dura tantissimo (lo si può comunqueusare anche mentre èin carica, magari con un powerbank), ma data la potenza a le dimensioni è scontato, peccato non abbia una USB C ma una microUSB. Nel complesso è un buon prodotto, confezionato bene, carino esteticamente, compatto e leggero e facilissimo da usare, consigliato!

Good product
Works perfectly. Not sure of the pin out on the headset/microphone. You have to use the one that comes with it because standard off the shelf headsets do not work with it

Delivery was a bit of a mess but the actual item works great!
I bought this speaker to use on my city walking tours and its proved to be amazing for a very reasonable price. I do my tours outdoors in high traffic and noise area and my tour guests can now hear my clearly without have to yell. great value

Excellent rapport qualité prix
En tant qu'enseignante, parler en cours avec un masque et une visière me fait forcer sur ma voix et les élèves au fond de la classe ont du mal à m'entendre. J'ai donc acheté cet amplificateur de voix qui est génial, le son est excellent, j'en suis extrêmement contente!
