Review: 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.

Works great in small-medium rooms, low price
This is basically a little mic and speaker set like the kind tourguides or other instructors use. It comes in unexciting packaging but it protects the device adequately. I am quite impressed with the quality of this product, I wasn't expecting a lot given the low price. It actually It can get nice and loud so you can even use it outdoors and for a big crowd, and the mic is clear with no feedback. This device is designed for human voice relay so music isn’t going to be any good over this. The ergonomics are fine, it is comfortable to use and wear for long periods. The battery seems to last all day, and the standby lasts at least 2 weeks in my experience. Charging is about 3 hours from nearly flat. I don’t have anything bad to say about this product, except maybe it looks a bit generic and cheap.

Simple and easy to use voice amplifier.
This voice amplifier by ResponseBridge arrived well-packed with all the accessories mentioned. Included in the package are the amplifier itself, the wired microphone, Aux cable, adjustable waistband, a USB charging cable, storage bag and an instruction manual. Out of the box, I have to admit that I was surprised that it was smaller than expected. But I’m glad that it works very well indeed. The setup is just a simple plug-and-play. As the headset is pre-paired with the speaker, you can use it straight away when it’s turned on. The sound is nice and clear, except when the speaker is in very close proximity to the microphone, there will be a little bit of feedback but other than that it's perfectly loud and clear. It would be useful to use during meetings or in a classroom. The battery is good, it can last for around 10 hours before needing recharging. It takes around 3 hours to fully charge it. While not a bad product, I feel that it would be even better if it has a wireless microphone and Bluetooth connectivity, however, for £35.78 (at the time of writing), seems like a justifiable price for the basic features it offers. Overall, it's a simple and easy to use voice amplifier that works as expected.

"Vox Populi, Vox Tu"
This ResponseBridge portable powered speaker and mic headset is a very handy lightweight utility that will amplify voice utilising the provided head-mounted microphone, but it also features a USB slot and an Aux mini-jack input so it can be used as a powered amp for other audio sources. The amp has an adjustable nylon strap so with the head-mounted mic the system can be used hands-free for speeches, presentations, demonstrations, band practise etc. It has a decent level of amplification, and this will create feedback at higher volumes if the speaker is too near the mic. It does feature a mic mute which is useful in presentations. Helpfully, the controls are all on the top of the amp so that everything is easily visible and within reach of the operator. It does lack a Bluetooth connection, but I don't see the absence of this sometimes problematic and erratic form of wireless link to be a major drawback, and in any case one can simply use the Aux input with a BT receiver is a wireless connection is desirable. I also prefer the fact that is is USB rechargeable rather than battery operated. It's fairly simple but well-featured and I think represents value at it's current price of just under £36.

Excellent for the presentation or a bigger meeting.
I have this portable, rechargable (22000mAh battery) voice amplifier in black. It arrived with the USB C charging cable, AUX cable, charger, waist strap, wired headset with mic, carry/storage bag and user guide. The device is charging fast and lasts for long on one charge. It has a built-in speaker. It looks and feels well made and of a decent quality. Quite easy to use. It made my voice much louder and clear without any background noise, but the sound it is quite directed. It is light and can be attached on the clip to the pocket or used on the adjustable belt strap. It can be also used to listen to the recording or music through the headset. Amplifier can be muted fast by pressing button. Headset is very light and comfortable to wear even for longer. Mic angle is adjustable. Excellent for the presentation or a bigger meeting. Will save my voice as I will not need to shout anymore on the meetings or trainings, but I will still be able to move/walk between attendees. Basic sound amplifier, but well priced and perfect for my needs, so I would happily recommend it.

Good battery life and very clear
This is the best portable speaker pa system I have reviewed yet as it has much better battery life and clear audio that sounds great for such a small speaker, the headset is comfortable and the whole system easy to use and more importantly not too heavy so easy to wear for extended periods too, it takes a USB C lead to charge which is also included with the set, all in all, a very good pa system.

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.

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

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!

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.
