Best Classroom Microphone System – Top 5 Picks

Since clarity is what you need and not necessarily volume, a good speaker and a wireless mic may be the best option. Together they make up a microphone system that is another way to protect your voice in the classroom while making sure everyone hears you.

A small portable amplifier may be all you need to talk to a small class of elementary school students, but if you need to speak in a large room and want very clear audio, then you should consider a wireless microphone that works with a high-quality speaker.

Several of the following speakers can be calibrated specifically for lessons and outdoor recreation. Some of them allow you to stream music or lectures from radio stations or online.

The speakers can be placed anywhere in the room within the given range with these best microphones for teachers. Since 75 percent of education is listening, it’s important that they not only hear the sound but also the intonation and subtleties of your voice to better understand what you are talking about.

In this section, I’m sure you’d be able to find the best teaching microphone system that is most suitable for your style.

8. Catchbox Plus Microphone System

Catchbox Plus is a system with 2 mics: a wearable belt pack microphone for the teacher and a soft, throwable microphone that will enliven your classroom exponentially. This is not a toy, even though it resembles one. It comes in bright colors plus black and white durable foam and the cover is fully customizable, meaning you can add school logos and colors as preferred.

It is suitable for any age. Yes, from preschool to Ph.D. programs and, for corporate meetings, it is a lifesaver. The throwable microphone and the teacher mic connect wirelessly with the system’s own receiver and the throwable mic can be tossed to anyone in the audience.

No more time wasted passing the microphone when you want an interactive or brainstorming session. The receiver has USB connectivity — so you can plug it straight into your computer, a speaker, or both.

This mic can be dropped, tossed, kicked, and slid across the floor of the classroom without damaging the high-quality mic inside. It’s perfect for large groups or outdoors where it is otherwise difficult for everyone to hear. My experience went from making it difficult for me to get everyone to participate in discussions to having to quiet the class and encourage them to wait their turn to speak.

Goodies I Found

  • Crystal-clear audio from every user
  • A strong but soft exterior
  • Easy to set up
  • Omnidirectional

Best For: In education, this is best for the times you want to give quiet students a voice. It is also useful for keeping noisy students engaged.

Since the box is thrown around the room, it can be sent to anyone. This encourages critical thinking because it could land anywhere.

In other words, it’s a fun and effective way to maintain your class’s attention. It breaks down invisible classroom barriers and boosts the confidence of the speaker.

As a voice-saver for a regular size classroom, this is probably your best option.

Goodies I Found

  • Rechargeable battery

  • A clip-on mic that can be used with a lanyard

Best for: This sound system is good for a large classroom, but it really shines when it is used outdoors, such as on a field trip or PE class.


10. Anker Soundcore Bluetooth Speaker

Upgraded, Anker Soundcore Boost Bluetooth Speaker with Well-Balanced Sound, BassUp, 12H Playtime, USB-C, IPX7 Waterproof, Wireless Speaker with Customizable EQ via App, Wireless Stereo Pairing

Best For: This is one of the best microphones for classroom use. It will also give excellent sound in a large space at school or outdoors as it is manufactured for people making documentaries or transmitting broadcast news.

The mic is quite expensive, and you may not need this much power for a normal classroom. But, if you give lectures in auditoriums or outdoors, you will be glad to have the extra power.

The speaker is also on the expensive side, but it is initially intended for a home theater, so you can be sure the sound is excellent.

Note: Some of these professional-quality speakers and mics may require licenses to operate, but if you operate them at a low power level, it shouldn’t need a license.

The FCC is currently evaluating the use of wireless microphones and the rules may change. If you don’t need this level of power, the other voice amplifiers I recommended may be just right.


12. innopow UHF Wireless Microphone System

The innopow mic is a wireless, handheld powerful device for large assemblies. It’s advertised as suitable for karaoke or wedding receptions and, of course, good for teachers – it will cover just about any classroom need that you have.

When voice problems occur, your teaching may become sub-standard. Teachers do things to make up for not being able to speak. It’s called presenteeism rather than absenteeism. You are at work, but not functioning on all cylinders. One of your most important tools is missing: your voice.

I did some research and found this article, which explains that the main problem is volume. I recommend you read it to get an idea of how serious the problem is. It concludes that amplification is the solution. Many voice disorders can be avoided or reduced if the teacher doesn’t have to speak loudly (read “yell”) most of the day.

Voice amplifiers to the rescue. They’re great when your voice is tired but you still have a lot of speaking to do before the day is done. If you’ve tapped out your voice for the day or week, a voice amplifier will allow a soft voice to be heard, even by a large group.

Amplifiers are essential for a major event or assembly. Just plug in the headset, and clip the unit to your belt or waistband and turn it on. If you support my idea of giving your voice a break, check out my detailed reviews of the best voice amplifiers for teachers.

How Amplifiers Work

Also called a speech assistance device, a portable voice amplifier is a mini public address system you can clip on your belt or wear around your neck. They’re relatively small units but provide a lot of volume when you need to speak to a large group at an outdoor event or even in an indoor assembly where the whole gym is full of students and teachers.

The small amplifier has a built-in speaker and a lightweight, portable headset. Some headsets are wired and some are wireless. If you need more amplification, you can download amplification apps for Android and iPhone. The sets come with a rechargeable lithium battery and can be operated with one hand.

Yes, my friends, I said one hand.

You can hold your clipboard, beverage, program, speech, or anything else you need in your other hand. Just plug in the headset and start talking. Use your normal voice and the people in the back of a large, crowded room will hear you. Take a look at this to get an idea of the possibilities.

This video doesn’t have a huge classroom, but the teacher doesn’t need to strain at all and all the kids can hear clearly no matter where they’re sitting or where the teacher is walking.

Different Kinds Of Amplifiers

There’s a big variety of voice amplifiers on the market that may be useful for teachers. Below, I’ve given you a list of the seven best voice amplifiers for teachers so you can get an idea of what’s available. The choice you make will depend on your usage.

For example, will you use it in a regular classroom, a large assembly hall, outdoors, or all of the above? Do you want to be able to play music or discussions you’ve downloaded?

I have given you a few of the devices I believe give high-quality voice amplification for the classroom. Using these devices is highly recommended for saving your voice as well as enhancing the learning experience for your students. If you primarily teach virtually, then one of the options for the best microphones for online teaching will be more applicable to your needs.

You can use amplifiers in conjunction with a variety of speakers. Check out the following article to learn more about classroom computer speakers that will make your teaching days easier on your voice.

4 Steps To Choosing The Best Voice Amplifier

Portable voice amplifiers for teachers have many features that will help teachers save their voices. The basic features that all of them have are a microphone, speaker, and powered amplifier. These are distinct from the best voice recorders for lectures, which specifically record sound instead of merely amplifying it.

They have volume control, and most of them come with a method to wear the device. Before choosing one that seems to suit your needs, I recommend you consider the features mentioned below.

Step 1. Start With The Battery

The first thing to look at is how long the battery lasts. Some batteries need to be charged every few hours, and some have instructions that the battery should be charged only when it’s completely dead. Also, some batteries last three hours, and some last 15 hours.

If you’re a music teacher or a physical education teacher, you may need a long-lasting battery so you only have to charge it at night. If you’re using the voice amplifier on an all-day field trip, the longer-lasting battery may be essential.

However, if you have time during the day to keep your device plugged in, a short-term battery may be enough for you.

Step 2. Consider Strength Or Volume

A voice amplifier is only useful if it helps people at a distance hear you when you speak in a normal voice. Before choosing a device, check the amount of area it covers with clear sound. Some cover 10,000 square feet and are suitable for outdoors, and some cover 5,000 square feet and are suitable for a medium-size classroom.

As you saw in the video above, the classroom wasn’t very large, but the amplifier made a big difference when the teacher walked around the room. If that’s all you need, you don’t have to spend a lot on one that fills a whole gymnasium with sound.

Voice Amplifier MAONO C01 can play music and receive input at the same time so you can use it as a mini karaoke set.

Step 3. Pay Attention To Portability

All of the devices I recommended are portable. This is a very important feature for a teacher, whether in a classroom or outdoors. If you’re just giving a lecture, you’ll probably have a sound system and stand at a lectern, but for most of us, movement is important while we talk to our students.

The above-mentioned devices are small, lightweight, and can be worn around your neck or clipped to your belt. Don’t forget that portability and batteries go together.

Step 4. Find An Amplifier That’s Easy To Use

We may vary in our understanding of technology, and some voice amplifiers have different features and connections.

If you want one that has all the bells and whistles, make sure you take the time to read the instruction booklet or find someone to explain it to you so you can actually use the features you paid for. For example, if you want to play music in the background while you speak on a certain subject, you need to know how to set it up for that.

If you plan to use your voice amplification system outdoors most of the time, you may want to consider the waterproof feature.

Then you don’t have to worry about protecting it if it starts to rain or the air becomes very moist and humid. A wireless voice amplifier for teachers can be your best option if you prefer to be hands-free.

Finally, make sure your amplifier is comfortable to wear around your waist or neck for long periods. The lightweight devices tend to be the most comfortable.

Tips On How To Use A Voice Amplifier

As teachers, we’re always trying to get the attention of our students. Many times, they stop listening because they can’t hear what’s being said and can’t follow. To remedy this, we start to speak loudly and even shout in some cases. When you use a voice amplifier, this is the first thing you need to stop. You can speak in a normal, even quiet, voice and still be heard at the back of the gym.

Another tip that will help the voice amplifier be more effective is for you to speak slowly.

If you teach at the primary level, you may already know how effective this is to help children to follow, but if you teach teenagers, you may have developed the habit of speaking fast in the hope that it’ll better hold their attention.

The voice amplifier allows people at a distance to hear you speak, even though they can’t see you up close. When you speak more slowly, people at a distance may be able to follow better.

In this video, you can see how a voice amplifier for teachers is being used and reviewed. Two of the products she discusses are on my list of the best voice amplifier for teachers:

You’ve reached this part! I hope this microphone system and voice amplifier review of ours has helped you find the one that is right for you. We have already chosen our top favorite; it’s your time now to tell us what’s yours and why!

But before that… if you’re also thinking of recording your lectures, you need the best classroom camera for best results.

Our Final Thoughts

Whether you teach physical education or a small kindergarten class, a portable voice amplifier will improve your quality of teaching while protecting your health.

There’s a large selection of features for every need, from the smallest classroom to the playing field, but the GIGAPHONE G100 made it to the top of my list because it has everything that I need to amplify my voice and it is also very convenient for me to carry it around.

If you can’t find a wireless one that gives enough volume for your needs, make sure it can be connected to another device such as computer speakers. To learn about the best computer speakers on the market, see my other blog post.

    Dear Emily, I’m 45 and have taught elementary school for 20 years without any tech support. I really appreciate your blog because it opens a door to possibilities I would otherwise miss. My voice is already starting to weaken and I can’t project it as I once did. Your article about portable voice amplifiers was my savior. Could you please give me your opinion of the best one on your list for a teacher, me, who just wants to talk to her class without yelling, but be sure everyone can hear? Thank you in advance for your hel

    1. Emily (author)

      I admire women like you who have devoted so much of your life to the education of the young.

I’m sorry to hear that your voice has been permanently affected but I do know something that will make a big difference. The RJoanna Jeremiah Portable Voice Amplifier is the answer for you. It is light, clips on your waist or pocket provides high-quality sound without surrounding ambient noise and the microphone fits like a headband. It has an excellent battery and is even effective outdoors. You will never have to strain your voice again during class. Who knows? When it is rested your voice may heal.

  2. TrishB

    Hi Emily,
    Thanks for your helpful article. In looking at #9, the microphone you recommend indicates it does not work with Bluetooth speakers. You paired a Bluetooth speaker with this which confused me. I have a Bluetooth speaker and so finding a microphone that would work with it seems ideal. Thanks again!

    1. Emily (author)

      Thanks for sharing your experience, it’s so important for me!

    What do you think will work best when wearing a mask? I teach high school chemistry and can already anticipate that it will be difficult for my students to hear and understand me while wearing a mask.

    1. Emily (author)

      I think the first one will do perfectly!

  4. Jessa


    Thank you for all this great information. My mother shared this blog with me as she is wondering if a voice amplifier would be beneficial as we head back into in person teaching amidst the covid. I teach English learners and am concerned on effective teaching with a mask and a face shield. My mother was thinking a voice amplifier might be good to help me keep my mask and shield on so I won’t be tempted to remove in order to help my students better understand me. But, we raised the question on how it would work with a face mask. Is it contaminating and more of a health issue in the long run? Would it be effective if using a mic on a lanyard (like the woman in the video) if wearing a face mask/shield? I would love your thoughts with this as well. Thanks.

    1. Emily (author)

      I think this wouldn’t be a great problem😉

  5. Pete

    just wondered if you tested any of the voice amplifiers in an outdoor setting; my experience is that most portable bluetooth devices etc are really completely inadequate amplitude wise and the range of usable frequencies are limited and the output simply insufficient to address a group outdoors. I have spend months now trying to find something practical but am not sure where to turn to. most of the modern devices seem to be designed for limited indoor spaces and most of them simply cannot cope with any auxiliaries or the amplifier has hardly any controls.

    1. Emily (author)

      Yes, I did😊 The first one

  6. Aline Lajoie

    Dear Emily
    Thank you so much for your dedication!
    I am a Music teacher.I teach K-6. Teaching is a calling for me.

    I will get one of you 11 top choices amplifiers
    And will let you know how well it will work! ;-) ;-)

    1. Emily (author)

      Thank you for your feedback 😊 Yes, wearing a mask is a difficult thing yet important!

    Thank you! I’m a music teacher and we’re heading back to a hybrid model of teaching in a few weeks. I was so glad to find your recommendations. You made my job easier.

    I wish I had known about voice amplifiers years ago! My second year teaching I got such a bad case of laryngitis. I only had a little cough in the morning, but as the school day progressed, my voice got worse and worse from all of the projecting I was trying to do to teach my students. By the end of the day my voice was so bad that I was whispering an announcement to one student to have them share with the entire class. A voice amplifier like the ones you reviewed could have made such a difference!

      Oh my, that does sound awful! I’m sorry you had to deal with that. I agree that one of the voice amplifiers here could be a lifesaver in a situation like that. And, like I shared in the article, there are so many other ways they can benefit your instruction even when you aren’t losing your voice. I’d say purchasing one is definitely worth it.

    Hello Emily,
    I’m looking to purchase these for the teachers in my building as we head back to in person learning in a few weeks. Is there a voice amplifier that is blue-tooth enabled and would sync/pair with the speakers in our multimedia boards we already have installed in classrooms so that we can take advantage of the built-in speakers. And do you foresee any issues with interference between classrooms if we did that?

    Thanks for any advice you can give.

      Hi! Thank you for the question. I’m sure preparing for the return to in-person learning is not a simple task. It looks like most of the voice amplifiers that are Bluetooth enabled are designed to pair with smartphones and other mobile devices to function more as an external speaker. From what I can tell, it doesn’t seem like they will pair with other speakers or multimedia boards. I’m not a complete expert on technology though, so I would suggest checking with your school’s IT person. Perhaps a wireless microphone would meet your needs.

    Hi Emily! I teach middle school band and also a performing cover musician. I need to not strain my voice and boy did I notice a huge difference yesterday once we all came back F2F. What mic can you recommend for myself and our chorus teacher so we aren’t straining and so that our students can hear us clearly? Thanks so much!

      Hi Kristin!

      I’d recommend Zoweetek Mini voice amplifier for you, I’m sure its power will be enough. It is very convenient to use, and its battery charge will last for a long time. Good luck!

    Hi Emily:

    Thanks for your blog and research! I have developed a voice disorder after many years of ministering both in the pulpit and classroom. Some days my voice is like a whisper. Do you have any recommendations of a system that I could put on my phone to magnify the whisper when I need to talk with someone? Thank You!

    1. Emily (author)

      You have three main options for amplifying your voice on a telephone. If you have a smartphone, you can download an app that will magnify your voice. Another option for a landline is Voice Magnifier. It is a device that connects to your phone and makes conversations easier for you and the listener.
      Finally, you can get a phone that has built-in voice amplification and control the volume your listener hears. With so many options, you can have clear, stress-free conversations in several rooms.

    I have purchased the Anker speaker and Bietrun microphone that you have linked in this blog. I have not been able to get the two devices to connect to one another. Is there a step that I am missing? I have not been able to find any online resources to help me figure this out. My students are returning to in-person learning next week and I am really hoping to have this up and running before they get here.

    Thanks so much,

      Hi Deborah! I’m sorry I don’t have a more specific answer to help you link the two. I would suggest trying to reach out to either Anker or Bietrun and see if someone is able to give you some pointers for connecting the two devices. Here are the links for the contact pages: Anker (https://www.anker.com/contact) and Beitrun (https://www.bietrun.com/contact-us)

    hello, i had an aker38 voice amplifier and it was great, but is there any amplifier that is greater than the aker? interms of sound distance and being able to carry around on you, so my question is, is there another portable voice amplifier that is much better than the ake38, interms of sound distance; im looking for something that can be heard further away and clear at the same time

      Hi! Thank you for the question! You may want to consider the YOCEWECA Wireless Voice Amplifier with Headset. This model is ideal for use with small or medium rooms with up to 200 people. It has a wireless headset and is also waterproof too!

    Hello! I am wondering if any of these mic sets are better for masks? Do they touch the mask and pick up friction sounds? I imagine they are worn on the outside of the mask?

    1. Emily (author)

      Wearing a mask certainly does introduce new challenges to teaching, doesn’t it? The good news is that most voice amplifiers should help make your voice louder and clearer for your students. Just make sure the microphone isn’t rubbing against the mask, and it should still be able to amplify your voice for students.
