Benefits of Using Voice Amplifier in Classroom

The main benefits of using such a device are two: dealing with hearing weakness and drawing the attention of the audience.

When you teach out there, you always have students who cannot listen to you as clearly as you think. And they at times feel shy to voice their opinion.

An amplifier will make sure that no one leaves the classroom confused and sad over such facts. If any student has a hearing impairment, they get a chance to understand your class as clearly as his classmates.

Also, this will reduce the additional questions from the confused students, thus reducing the workload.

Then there are those young men who do not want anybody to pass the next exam! Those chatterboxes never cease the side-talk.

Enters the amplifier into the classroom and shuts those geniuses for good. Not to mention the relief you feel by owning the best voice amplifier for teachers.

What’s also worth mentioning is that the amplifier will hang down from the neck or settle down in your waist without producing any discomfort. It comes with a back clip to offer such convenience.

Now, is the battery durable? The battery boasts 1800mAh, so I’d say that durability is covered. It runs for 12 straight hours.

I am also impressed at the ability of this unit to cover the furthest corners of the rooms. You can do more than alright with 10 watts max capacity, be assured.

For, you are looking at 10,000 square ft. of clear sound spreading. And the model requires only 5 hours of charging when the battery is down.

You should also check out the adjustability of the wired microphone. However, one user didn’t like the quality of the sound.

Another one couldn’t keep it running for more than 40 minutes before it needed charging again. And a patient with vocal paralysis didn’t find any use in it.

Now, the most fantastic thing about this is that it’s more than just an amplifier; it acts as a Bluetooth speaker too. And it connects with devices that are up to 33 feet away.

What’s also great is that it doesn’t weigh much, thus allowing you to take it where ever you want. If you are a teacher communicating with more than a hundred chaotic students, this might save your day.

Moreover, you will appreciate the long-lasting battery that serves you for about 12 good hours.

And how long does it take to charge the battery? Not more than 5 hours or so. Yes, a 2800mAh battery is supposed to offer that kind of impressive performance.

You will also find it useful if you are suffering from any vocal disease. And users have appreciated the excellent volume of the unit.

Now, as for drawbacks, one user had to endure bad engineering of the device. He changed the first unit with a second one, and still, he was upset with the non-functional buttons and troublesome mic input system.

A personal voice amplifier with 10 watts sound is difficult to pass by without considering.

So, here we are reviewing such a device with a couple of excellent features. The unit will spread sound in a room of 1000 square meter size. Also, it will draw the attention of your family if you are having vocal problems.

Now, the best feature is the microphones included in the package. Yes, I just said it, the product has TWO MICROPHONES.

Manufacturers thought that the wireless one alone wouldn’t be impressive enough, so they had to blow you away with an additional wired one.

I am counting on the wireless voice amplifier for teachers, though, as it comes with UHF technology that offers extreme resistance to all sorts of interference.

You can also remove the wireless hook anytime. Now, how many people will the sound reach clearly? Well, not less than 50 people.

Moreover, the battery will run for 8 hours after being recharged for 5 hours. Now, one customer wasn’t happy with how the headset refused to stay charged for him.

He couldn’t use it for more than 2 hours before needing to recharge it. For another user, the sound cut out frequently.

SHIDU Wireless Voice Amplifier and Classroom Microphone System

Are you looking for a classroom microphone system for luxurious teaching? Then you are in the right place. This unit will serve the purpose of a power bank!

If you doubt that I am not thinking clearly, then wait until I inform you about the Bluetooth, U disc support, one-key recording, and micro SD card compatibility.

I am also astonished at the long battery life of this model. It will provide a non-stop service for ten long hours.

You have got to check out the 4400mAh battery to know what I mean. However, you will enjoy such durability only when you aren’t driving everyone nuts with high volumes.

The headset mic, though, has shorter durability. It will run for only 2-3 hours. Now, what about the sound output? Glad you asked, and I’ll be thrilled to answer that it’s an 18-watt device we are dealing with.

So, if you want a room full of 150 people or so to hear you clearly, you aren’t asking for too much.

Another remarkable feature is the 2-in-1 microphone system with a removable ear hook. Now, one user found the mic crackle after a while during outdoor uses.

5. WinBridge Rechargeable Portable Voice Amplifier for Teachers

WinBridge WB001 Rechargeable Ultralight Portable Voice Amplifier

Do you want a compact speaker to go easy on your voice? Then check out the device with an excellent adjustable microphone. What’s cool about this microphone is that you can benefit from its superb design and position it nicely proximal to your mouth.

What’s also lovely is the durability of the battery. Yes, 5 hours might not be outrageously long, but you won’t get a chance to complain about sound clarity during these hours. I also like the belt strap the product comes with. It lets you wear the amplifier fashionably.

You will also find the headset comfortable. And how much comfort means when it comes to headsets! No falling off, no hurting the scalp – none of those annoying businesses. You can also clip this classroom microphone on a wristband for extra comfort.

Now, things would’ve been more significant if one user didn’t find the circuit failing when he brought the microphone very close to the loudspeaker.

It was only later that the poor guy learned about the funny ways an amplifier works. He warned about not bringing the two parts too close to each other.

Another one was unhappy with the battery life. Moreover, the headset was “cheaply constructed and poor-fitting” for another buyer.

Highlighted Features:

  • An adjustable microphone with beautiful design
  • Generous durability of the battery
  • The belt strap lets you wear the amplifier fashionably
  • The positioning of the microphone proximal to your mouth
  • Comfortable headset

6. VoiceBooster Amplifier & Mp3 Player & FM Radio

VoiceBooster Amplifier & Mp3 Player & FM Radio

Check out this amplifier that is built to serve every purpose you can think of. A voice amplifier operating the definition of an MP3 player – can it get any better than this?

What’s also striking is the compactness of the unit. And despite its small size, it covers 7000 square ft. in the street. Yes, it’s a street device!

What I also like is the battery life of this unit. It provides a clear and loud sound for a reasonable 10-hour period before needing recharging.

Also, the battery will last two years at the least. What’s more, the product comes with a handful of accessories.

You will find charger cable, headset microphone, MP3 cable, user manual, waistband, carry bag, etc. – all included in the package.

I am also flattered by the micro SD port and USB port. Manufacturers couldn’t make this classroom amplification system more versatile.

However, one user received uncomfortably heavy feedback. He blamed it on the poor design of the unit. For another one, it didn’t help in hearing-impairment. And the sound quality was mediocre for another fitness-professional.

Highlighted Features:

  • A voice amplifier serving the purpose of an MP3 player
  • Covers 7000 square ft. in the street
  • Clear and loud sound for 10 hours before needing a recharging
  • The battery will last two years at the least
  • The micro SD port and USB port

7. Bietrun Classroom Voice Amplifier with Microphone

Bietrun Classroom Amplifier with Microphone

When a product offers you a 2000mAh high-powered battery and claims of 20 hours of non-stop service, you have to check it out.

So we did and loved what we found. A clear sound covering 1000 square ft. was enough to impress us. But, the unit had to have 13 watts on top of that.

Another glorious feature is the USB compatibility to charge the device. It will take only 5 hours to make it ready for a long service. What’s also crazy is that it supports TF card playback. Moreover, you can use 3.5mm AUX audio input.

I also find the display to be an attractive feature. Not many devices will offer you this. Whether you’ve chosen one-touch recording or you are listening to the flash drive files – it all shows on display.

You will also appreciate the minimized squeaking between the amplifier and the microphone.

As for cons, one user was slightly disappointed with the wireless mic for its short battery life. Another customer noticed some feedback at the highest volume. For another one, it was strangely incompatible with a 3.5mm port.

Highlighted Features:

  • Clear sound covering 1000 square ft.
  • USB compatibility to charge the device

Now, if you love classic designs of things, you would adore this unit. Every single part of this beautiful device screams retro. And how many people can listen to its clear sound? Well, about 100 people will benefit.

Now, what distance can the amplifier deal with? Well, you can go 50-ft from it in any direction, and the device will still amplify your voice.

What’s also cool is the portability of the microphone. And the volume adjustment seems to be comfortable with the included signs.

You will also find the buttons fun to press. They are strongly made for passing the test of time. Moreover, the device will act as a Bluetooth speaker. And the input modes are quite a few to offer versatility.

What’s also great is that you can connect the headset microphone and the handheld one simultaneously.

However, one user wasn’t happy with the headset mic. It refused to hold the position, and when he wasn’t holding it close to his mouth, the speaker didn’t collect the sound much.

And the movable arm was flimsy for him. Also, one user had to endure a weird 3-second long announcement now and then.

Highlighted Features:

  • Handheld Bluetooth microphone and wireless headset mic
  • About 100 people will listen inside a room
  • Portability of the microphone
  • The volume adjustment seems too comfortable with the included signs

Now, what about the build of this unit? Well, the device will withstand shock and drizzle, alright.

I also appreciate the lightness of this model. When you take classes for long periods, the last thing you want is a massive amplifier to burden you.

Also, it comes with a compact design to go with any kind of setting. What’s also impressive is the durability of the battery. It runs for about 10 hours.

And once you charge it for only 3 hours, the battery is full of life. You will also like the variety of mics for this device.

Moreover, users have been happy with the fact that it allows no feedback. And having a class full of 100 or so students listen to you clearly would be a fun experience for sure.

However, the charging port wasn’t that great for one user. He had to twist the port around to make it work correctly.

Also, he would’ve loved markings on the volume dial. Another user was annoyed with the noise. He stated that it was “sharp and unbearable.”

Highlighted Features:

  • The Neodymium magnet device boasts 30 watts
  • Won’t annoy with any noise
  • Will withstand shock and drizzle

Therefore, you can save some money by buying this all-in-one unit. And the fact that its light and compact makes it a great option.

The model comes with 30 watts sound that will reach the furthest corners of a 25000 sq. ft. room. So, if you are training a class of 100 people, you won’t have to strain your voice. All you have to do then is choose the maximum volume so that everyone hears you.

Another wonderful thing about this product is the removable handle it comes with. You won’t have to be afraid of dropping the useful possession once in a while with such a unique feature in place.

I am also counting on the 2500mAh battery. It will run the device for 5 hours straight after you charge it for equally long.

As for cons, one user found the midrange, only offering a clear sound. And his recorder didn’t record any other inputs but the mic. For another customer, the battery wasn’t durable. It didn’t hold a charge at all after one month of use.

Highlighted Features:

  • Bluetooth, recording, echo, and audio jack
  • 30 watts sound that will reach the furthest corners of a 25000 sq. ft. room

Things to Consider Before Buying Voice Amplifier for Teachers

If you can manage to buy a great device, you will use it for years. Otherwise, it will become trash in no time. To make a smart purchase, you need to consider a few things.

The market comes with too many alluring products. And it can be highly confusing when it comes to choosing one unit out of all these.

So, let’s talk about the factors you need to learn about before going for the purchase.


The most important thing about a sound amplifier is its power. Let me elaborate on this matter a bit so that you don’t end up buying a fancy device with low wattage.

It’s a factor that will determine the reaching capacity of the sound. So, the ideal power will vary according to the size of the room.

Say, you have a classroom to attend to where there are 100 students, and they are waiting to eat your brain out with all the gossips about everything and anything! Then you need to buy a device with a minimum of 10 watts.

Only this way, the sound will reach all the corners of the rooms. Any less wattage than that, and you have a bunch of naughty folks to deal with. And for street events, you might want to increase the power.

Now, we’ve seen excellent products with wattages as high as 30 watts. Finding a good one won’t be a big deal as long as other essential features are there. So, check out the maximum power output before anything else.

Battery Life

The second most important thing is the durability of the battery. Customers of amplifiers seemed to pay much attention to this factor.

And there’s an issue with cheap products out there. Sometimes the claimed battery life is far from the truth when it comes to using the devices regularly.

Now, you can solve this problem by merely going through the customer reviews for a specific product. This way, the buyers can enlighten you about the reality of the situation.

So, what is the minimum battery life you should settle down for? Well, it shouldn’t be less than 5 hours if you want to enjoy convenience.

And some batteries will offer you up to 12 hours of uninterrupted service. If you can get your hands on one of them, do so while considering all the other features.

Build of the Headset and Microphone

The headset must last for long. Also, it should provide comfort for you to enjoy your work. Moreover, make sure that there are minimized feedbacks.

And there shouldn’t be any unpleasant noise emitting from the device. I would also suggest that the microphone be easily adjustable.


It’s nice to open a package when you find all the necessary components inside. Even if there isn’t any need for too many accessories for an amplifier, it never harms when there are a few, though.


If you can wear the device on the neck or waist, it would be cool. For easy portability lets, you concentrate more on the work rather than managing the device itself. We’ve reviewed some highly portable products with incredible compactness and lightness.

Also, the amplifier should provide an SD port and features like this. See, in terms of versatility, people are willing to spend a few extra bucks. And once you enjoy the functionality of an MP3 player in a voice amplifier, the money will seem worth it.
