Perfect for my classroom
I love this amplifier. I’m a middle school teacher and this is perfect for me. It’s super handy and easy to carry. Awesome sound quality; very audible. Really helped amplify my voice in the classroom. This should be in every teachers’ wishlist.

Perfect for teaching outside!!!
Teaching PE outside its important to be heard over lawnmowers sometimes, and this is an absolute life saver. I can use a speaking volume and students hear me over quite a long distance! Great item!

Useful
This amplifier is really useful for teachers like me. I really like this because it is lightweight and for long time use without charging again and again. Small flaws for me is that you need to put the mic really near to your mouth so it will be that loud. But over all I will recommend this to my colleagues.

Game changer amplifier
I love this product, the battery life is better than my brand before. I tested outside the field and the volume is loud. I love this product it is lightweight and don't notice that you're carrying something. The battery life is long lasting, I used this this outside as a speaker and it works louder than the speaker that I bought a year ago. If you're working on a field, I recommend this 100%. An awesome customer support is ready to help in case you don't know something about the product. Make sure you check coupons to save more before check out. Thanks

Disappointed, mute feature doesn't work, volume difficult to control
The reason I selected this product over the many others was because of the MUTE feature. Alas, the MUTE button does not mute your conversation. Have no idea what the button does, but it does not mute your conversation, which is essential in a classroom setting. I don't want to broadcast to other students my conversations with individual students. Also, the volume buttons are difficult to use. You have no visual way of seeing current volume setting. You just have to keep mashing the buttons and testing microphone and hope you get close to what you want. Worse, when you power down, it doesn't remember your previous volume settings. Very disappointed. Considering returning it. Will have to spend more to get a working MUTE function.

Not quite up to par
The headset does not work as it should. It does not reach far enough down and is impossible to use around the neck as suggested in the description because you cannot turn your head and speak into the mic. Also found the voice quality not perfectly clear. A little tinny as well.

Device for the win!
Easy to use. As described. Wonderful company to work with! As a teacher I would recommend this product for those that need a voice amplifier. Rechargeable batteries and mute button!

Voice saver!
This product is a voice saver. I don’t need to force my voice for others to hear me. It is very useful during the student assemblies. I recommend this product.

Amplificador voz
Deshacer los meses estoy trabajando en un gimnasio impartiendo clases de baile y entrenamiento personal. Al principio solo contaba con un grupo reducido de personas pero cada vez se van apuntando más y más, y mi voz lo va notando. Trataba de buscar soluciones y lo que se me ha ocurrido fue un pequeño micrófono con un amplificador como el que vemos en las imágenes. A continuación voy a contar las características más destacables del producto así como sus inconvenientes. Para comenzar, decir que la caja incluye el propio micrófono con el amplificador, el cable que carga el amplificador con su respectivo cabezal, una bolsita para guardar el amplificador y un cable para conectar el puerto AUX. 🎙 La calidad del volumen es buena y puedes modular en el propio amplificador el volumen con el que quieres que te oigan. 🎙 Otro aspecto positivo que le encuentra el producto, es que el micrófono se pone alrededor de las orejas y resulta muy fino y poco pesado lo que favorece y facilita el desarrollo de las clases manteniendo una escucha activa con todos los participantes 🎙 El modo de conexión es muy simple pues el propio micrófono incluye un cable que se conecta directamente al amplificador y permite que el amplificador ejerza su función. Debes tener cuidado de que el micrófono tenga cierta separación con el amplificador para evitar interferencias 🎙 El amplificador por la parte trasera incluye una pequeña pinza que puedes conectar en la parte trasera del pantalón (como es mi caso)., de esta forma no notas ni se te cae en ningún momento el producto. 🎙 la batería dura durante horas y horas y además el cargador incluye el cabezal, cosa que a día de hoy es difícil encontrar ❌ Como contra, me gustaría decir que quizás el tamaño del amplificador es un poco grande y puede resultar incómodo en el desarrollo de las clases. No obstante, si lo que buscas es calidad es lógico que quizás el tamaño se vea reflejado en la misma. Estoy muy contenta con el resultado, de esta forma mi voz no se ve tan perjudicada y me aseguro de que todos los participantes de la actividad entienden y escuchan con claridad los ejercicios propuestos. Si vives una situación similar como la mía te lo recomiendo

Small and light and amplifies my voice very clearly
The small size of this voice amplifier is what first impressed me when opening the box. It's very small and light which means it's extremely easy to hold or have clipped to you (there's a clip on the back to allow you to clip it to clothing such as trousers etc). It comes in a small little drawstring bag. A cute little touch from the seller but not really necessary for me. It may be small but it does pack some power though. I have been using it for some presentations I have been doing for work, in reasonably large conference rooms, and the sound and volume has been really good. There's also a very useful 'mute' button which cuts the sound out immediately. This has come in handy several times so far and works well. It's rechargeable and there's a power indicator light that allows you to know if you made need to recharge it any time soon. The battery has been pretty good so far though and lasts a while. There are aux and microphone slots available. The earphones are light and easy to put over your ears and off. The microphone can be swung up and down away from your mouth so you can move it out of the way of your face if you need to. The sponge is not very thick on each ear but this is only a minor issue to me really. For the current price of £35.78, this does a great job of amplifying my voice clearly and loudly, and is comfortable to wear and easy to use.

Amplification Achieved
Purchased for my 8 year old (yes, yes I know it makes him louder) for Christmas and overall pleased with ease of use and battery life. We have been treated to an on going commentary for the past week on where things are located, how to find them, and even what's on the menu for dinner. So far so good!

Buena herramienta de trabajo
Si eres de los que acabas con problemas de voz de forzar mucho o de muchas horas hablando, este dispositivo es la herramienta que necesitas. Fabricado con buenos materiales, tiene un buen acabado y un buen diseño. Es fácil de usar, y además te trae muchos accesorios incluido la bolsa de transporte. La idea es que te ayude a que los demás te oigan sin tener que forzar ni elevar la voz. Así si das clases, o eres, por ejemplo, guía turístico, te viene genial esta herramienta y, además, como funciona a batería, pues nada de pilas. Lo pones a recargar y en un par de horas tienes autonomía para el día entero. Termino comentando que no es que amplifique como para que te montes una fiesta, pero sí lo suficiente para los menesteres que ya te he comentado.

Handy portable amplifier speaker
You receive what is a very well made portable speaker amplifier, its light to carry and a very useful machine. This is ideal if you’re are giving a presentation or need to speak to an audience where you don’t have an amplifier and speakers, what makes this even better is it rechargeable with its own battery, again this is ideal if talking outside. I run events, on the odd occasion I need to speak to all our stall holders and raising your voice is not always pleasant, this is fantastic, pop it on, jump up on stage and I have no need to raise my voice, really impressed Easy to use, it’s not Bluetooth, I’ve had a couple of these that are, this has a 3,5mm input for connect an audio source, I’d have preferred bluetooth. The sound is okay, not amazing but its not rubbish You receive what is a very well made portable speaker amplifier, its light to carry and a very useful machine.
