Buyer’s Guide

There are many things that you should look at when you are looking for the best voice amplifiers for teachers. To help you out with your difficult decision, we have put together a buyer’s guide for things to look out for when you’re purchasing one. 

Battery Life 

Battery life is a very important thing to focus on when you’re shopping for voice amplifiers. You will need one that lasts through the day without needing to be charged.

When you are looking at this you will need to consider how many hours each day you will need to be using the device and make sure that the battery will accommodate for this. 

Bluetooth Vs Wired 

Some voice amplifiers use bluetooth to link up the microphone to the speakers, while some use a wire. If you prefer to be able to move freely around the room while you are teaching, then it is best to consider the bluetooth option.

This will also help if you want to put the speaker in the middle of the room, or nearer the back and you wish to stand at the front. The bluetooth option gives you a lot of flexibility. You may prefer to use a wire microphone though. This is more reliable in terms of staying connected. 

Size Of Your Class

You should consider how many people are in the room that you will be addressing, as well as how big the room is. If it is a small room and fewer people, you won’t need as powerful a device.

However, if you are looking for a device that will allow you to address a large group of people, or a lecture hall, then you may need a more powerful device.

If you are speaking outside, you will also need a powerful device, as the sound does not travel as well outside and it will get lost more easily.


We haven’t looked at any devices that aren’t portable. As a teacher, it is very important to be able to move around while you talk to your students. You need to be interactive and adaptable and you don’t want to be tied to one spot.

That is why the product’s portability is very important. You want to look for a small and lightweight device that can be easily carried around with you.

You also want to look for a device that you can clip on to your jeans, or tie around your neck or waist. This will allow you to easily move around whilst teaching and still see all the benefits of the device. 

Ease Of Use 

It is important to find a product that is easy to use. If you are hoping to use the amplifier outside, then you may want to consider whether the product is waterproof or not. You don’t want to cause damage to your product because you have taken it out into the rain.

Look out for the features that are specific to you and ensure that you are getting everything you need in your amplifier. It is best if you have a hands free device so that you can teach using your hands.
