1) Movo WMIC50 2.4GHz Wireless Lavalier Microphone System

We’ll start off with one of the finest affordable wireless mics. The Movo WMIC50 is certainly a fine option for people who need a decent classroom mic; while simultaneously being on a tight budget.

However, we should point out that this mic has some downsides. You can’t switch the transmission frequency or channels, and there is no indicator of volume levels on the receiver or transmitter.

Still, it gives you one of the things that are most important when it comes to classroom mics — and that’s the option for cordless recording! You get a great paper microphone, featuring a transmitter that you can attach to your belt via a clip, along with a tripod mount and a camera shoe receiver. 

This is a 2.4GHz system, but it allows for internal boosting at more than a 150 foot range. In other words, you won’t have to worry about whether this particular wireless microphone system is powerful enough for your classroom — because it most certainly is. 

Also, the manufacturer has certainly proven that they value their consumer base highly — with a one year warranty and a great support system for any kind of issues you may encounter. Plus, the audio monitoring solutions found inside are pretty great, with an isolated microphone which can directly communicate with the transmitter — in other words, there’s no need to pause and replay to see if your audio recording is functioning as it should! 

Now, there are a few downsides to consider as well. Apart from the absence of a volume indicator which is a really important quality-of-life feature, you’ll find that this system also lacks a decent battery life. In a single charge of batteries, you won’t be able to record more than four hours. For teachers that don’t want to replace batteries every single day, this can be a bit of a problem.

Pros:

●  Affordable

Cons:

●  Lack of channel changing

●  Lack of volume indicator

2) Sennheiser AVX Digital Wireless Microphone System

Next up, we’ve got another microphone and voice amplifier system that’s going to be of use in the classroom. However, we have to mention that this Sennheiser model is more widely used for camera recording instead of the classroom. You’ll find it more often utilized by DSLR cameramen outdoors.

Still, it’s fairly simple to set up and easy to use in general. The only problem is that it doesn’t have a headphone output on its receiver.

However, as you’ll see below — the Sennheiser system has more than enough excellent features to make up for this. While it may be suited for more professional audio users and creators, it’s still bound to work wonders in your classroom; as long as you’re prepared to pay a somewhat hefty price. 

If you are, though — you’ll enjoy an incredibly easy setup process. There’s no talk of losing countless hours on fiddling; it’s all a fairly simple plug and play process. There’s also the P48 Phantom power core that switches off automatically to conserve energy; an important feature for anyone looking to conserve as much power as possible.

For people who are avid film lovers, the accessories of this set that enable easy DSLR use are definitely a boon; though that’s not as important for teachers looking for a decent classroom microphone. However, what you do get with this package is something that most other wireless microphone sets don’t give you — and that’s a complete autonomy when it comes to audio management.

If you’re someone who’s genuinely interested in audio equipment, you can fiddle around with this set as much as you like. However, if that’s not the case — you can enjoy everything from auto frequency management to auto audio level control. You don’t have to do anything manually if you don’t actually want to. And let’s be realistic — if you’re a teacher who doesn’t have neither the time nor the inclination to fiddle around with audio gear, this is definitely a huge benefit for you. 

Apart from that, we should also mention that the manufacturing quality in these audio sets definitely excuse their price. All of the equipment has a distinct metal housing that protects it from both wear and tear and accidental damage — and the entire product is produced in a premium-quality factory in Germany. 

Pros:

●  Quick pairing and set-up

●  Manufacturing quality

●  Sound quality

Cons:

●  Lack of headphone output in the system’s receiver

3) Pixel Wireless Lavalier Microphone

The Pixel Wireless Lavalier model is certainly an example of wireless recording equipment for anyone’s pocket. If you’re looking for a budget pick among our list, this would probably be the best choice. You won’t find a lot of neat extra features here — but what it does, it does well.

Its sound quality is excellent, at least for this price. And for stuff like video recording, lectures, or bigger classrooms — it’s more than sufficient. It has a range of about 70 meters, making it more than adequate for most indoor areas.

Though,that’s not the only thing you’ll love about this microphone set. In addition to being a decently performing device, it is also quite versatile. You will find that you can attach it to a variety of other devices that it works with beautifully. For instance, there’s the mount for DSLR cameras — though not something most school teachers would use — as well as tripods, smartphones, and other kinds of camcorders. 

Apart from teaching, this kind of microphone system is often used for entertainment purposes. These days, people use them for vlog recordings, YouTube livestreams, and all sorts of other content — not to mention other professional presentations outside of your classroom. 

The audio geeks among you will be thrilled with the 36 channels that you can pick from; allowing you to avoid even the smallest possible signal interference. There’s one receiver that triggers one bodypack transmitter — so you won’t have to fiddle around with this all too much. 

Apart from this, you’ll also find an excellent real-time monitoring function; allowing you to continuously test whether the equipment is functioning normally, without worrying about any interruptions during your recording session.

Overall, this lapel microphone will lend a more professional atmosphere to your classroom. And as we’ve mentioned before, it has a great range — up to 70 meters, though only in open areas. Still, you won’t need as much in a closed classroom. When it comes to battery power, the story is a little bit different — the microphone is thoroughly average in that department, seeing as it gives you enough power to work for about 6 hours. 

Though, there is support for additional power if you find yourself needing it. Finally, the low cut filtering functionalities allow you to have the clearest possible output even at low frequencies, and the manufacturer’s proprietary noise suppression technology does a decent job as well — you won’t feel like any wind or other environmental noises are detracting from the quality of your recording. 

Pros:

●  Affordability

●  Transmitting range

Cons:

●  Lack of extra features

4) FIFINE Wireless Microphone System

If you need something even cheaper than the abovementioned Lavalier, the FIFINE model will definitely do the trick. However, you should keep in mind that this is far from a perfect wireless microphone system. Sure, it won’t set you back more than $35 in most places.

However, the audio recording tends to have random little cuts if you move around too much. Seeing as many teachers love walking around their classrooms while they talk, this could be an issue. However, if you’re looking for the cheapest possible option — this is it.

Still, advanced users that are looking for a great classroom microphone will appreciate its wealth of UHF frequencies — this wireless microphone offers a selection of 20 different frequencies, ensuring an interference-free and seamless audio experience. Plus, you can conveniently monitor the current status of the device using its clearly visible LCD screen.

There, you can find all of the information you’ll need — like the low-battery warnings, indications for the receiver battery, and general system info. And this kind of convenience is exactly what this microphone system is known for; with rare audio dropouts, though. But if you disregard that, you’ll find that the amount of static is surprisingly low for a microphone in this price range. 

You can safely use it at distances of around 40-50 feet — which is realistically more than enough for most classrooms. Plus, you don’t need to be an audio geek or a techno wizard to set it up and get it working; every one of these wireless transmitters has paired ID synchronization, so there’s no fiddling — all you do is plug the microphones in or out. 

And let’s face it — people often underestimate how much of an active audio performer a teacher can be. The best-regarded lessons are the most energetic ones; which is why you can’t be fiddling around with a microphone in your hands all the time. With that in mind, the FIFINE system offers a low-visibility tie clip to ensure easy hands-free usage of the microphone. 

Even if you want to do more than teach, you’ll quickly find that this microphone provides absolutely anything you want in a versatile audio device. Firstly, it is compatible with everything from PA speakers to sound boards and mixers; conference gatherings and classrooms alike benefit from its presence. 

Pros:

●  Incredibly low cost

●  Affordable batteries

●  Ease of use

Cons:

●  Audio cut-outs at random intervals.

5) Giecy Voice Amplifier Portable

Finally, we arrive at one of the best wireless microphones and voice amplifiers for teachers in 2020. The Giecy Voice Amplifier is everything you need when it comes to audio in the classroom; all in one neat, portable package.

First of all, you should know that this device has a battery life of 15 hours; more than enough for one day of work in a school. Also, it’s got an excellent Bluetooth connectivity feature; along with clear audio. Not only will this amplifier help you enhance the strength of your voice across the classroom — but it will also be as clear as you want it. There’s no distortion and noise to be worried about here, even at longer ranges. 

In fact, while this amplifier is a great option, it might be something of an overkill for the average classroom — with an insane coverage area of about 1000 square meters, it’s more than loud enough to project your voice across even the biggest classroom. That’s why preachers, panel hosts, and all kinds of other professionals that fill large rooms use it as well. 

With the device, you’re also free to make any volume adjustments that you’d like — though at higher volumes, at the expense of sound clarity. And while we’re on the topic of small drawbacks — this is touted as a portable amplifier, and it’s definitely small enough for you to carry around on your shoulder. But, even though it’s got a clip-on option for your belt as well, it’s a little bit too hefty for that sort of thing; somewhat detracting from its famed portability.

Still, the microphone more than manages to ensure that you get all of its weight’s worth — for instance, the rechargeable lithium battery found inside has an incredibly high capacity and safety index, ensuring you can safely use it for up to sixteen hours on a single charge! 

Unlike most others on this list, this microphone can also be used as a bona-fide bluetooth speaker; letting you record wirelessly without any transmission issues. Finally, there are plenty of playback options to choose from — the USB flash drive being the most practical one. 

Pros:

●  Bluetooth connection

●  Long battery life

Cons:

●  It’s a bit weighty

Other Great Microphones

Alvoxcon Dual Wireless Lapel Mic

When you’re looking for a great classroom microphone, there are a couple of things on your mind — and the Alvoxcon Dual Wireless Lapel Mic ticks all of those boxes with ease! Firstly, the microphone definitely makes good on its promise of high-quality sound, seeing as the performance it delivers is simply outstanding. The sound is pretty clear if your classroom itself isn’t noisy, and you get a belt-pack transmitter which is capable of providing noise cancellation for a hundred feet — though this is one of those areas where the microphone doesn’t exactly live up to the manufacturer’s specs.

Indeed, we have to point out that the noise suppression isn’t as great as you’d like, with some extremely hissy sounds at longer transmission ranges. That being said, it’s definitely one of the best clip microphones you can find for a reasonable price. It’s compatible with phones, for which you get a special adapter cable, and DSLR cameras. Unfortunately, using them directly with computers is not possible; however, smartphones provide enough features nowadays that this shouldn’t be such a big problem. 

Also, the sometimes lower vocal performance of this microphone is increased with the condenser headset; providing you with a clip you can easily put on your shirt collar, and allow your hands to be free for the most effective lessons possible. 

Apart from this, you should also know that this dual-channel microphone provides you with decent volume control and multiple frequencies to choose from; all you need to do is to use the transmitter buttons which will let you choose the frequency you want, and the volume level that’s perfect for you without interference. 

Pros: 

  • Great volume levels
  • Clear sound

Cons:

  • Not compatible with computers

Zoweetek Voice Amplifier

Our next pick is a small voice amplifier — but one that’s guaranteed to save you a lot of throat ache! It doesn’t give you much recording or processing power, but it does what you primarily want in a classroom microphone — and that’s voice amplification. 

With that in mind, the fact that it doesn’t have any static or distortion even in crowded classrooms is definitely a boon. Plus, you can safely use it with groups of up to a 100 people, knowing perfectly well that your words will reach them all. And its compact size means you can easily clip it on your pocket or your belt — it weighs about a third of a pound, so it’s definitely among the lighter options here! Also, there’s a mic port you can utilize for tablets, iPads, computers, or other smartphone devices. 

Interestingly enough, the product comes with a neat waist belt you can use if you don’t wear a belt of your own while using this. The only downside we’ve found is that the lithium battery that comes with the product does not last as nearly long as advertised — while the manufacturer says that it can last a half of a day, we’ve found that it struggles working past a couple of hours. But that’s what you get for such an affordable product — they had to cut corners somewhere, and they did it with battery life rather than audio quality. 

Also, the voice amplifier does more than strengthen your voice — you can also use it as a powerful classroom MP3 player. That’s handy when you want to show your students some examples via video lectures, TED talks, etc. 

Pros:

  • Audio quality
  • Long reach

Cons:

  • Subpar battery life

Voice Amplifier MAONO C01

Our next classroom microphone of choice is the Maono C01 — a small, rechargeable, lightweight microphone. Its biggest downside is something we’ll point out right away — it’s partially wired, so it doesn’t completely fall into the category of wireless microphones. However, it’s benefits more than make up for that small bit of additional wiring that you’ll have to put up with. 

There’s a neat LED display on the device, and a waistband which enables maximum ease of use. Though the sound coverage is a bit lower than with the previous microphones that we’ve reviewed, it’s still a decent 6,000 square feet. Best of all, it’s a cardioid microphone; meaning it’s going to be perfect at collecting only the sound of your voice, without any background interference or noise. 

With that in mind, you’ll happily be able to use it for outdoor classes and events as well! And while this isn’t so important, it comes with a cute gold design that gives it a degree of elegance beyond the usual silver and black microphones. 

As you can see, its major downside is the additional wiring. However, it also gives you a great LED indicator to make up for this, letting you know precisely when you should pause to charge the battery. That way, as long as you pay attention, you will never run into a situation where you’re suddenly out of juice in the middle of a lesson.

Plus, it’s great for playing music as well — while receiving simultaneous input from your voice. Basically, there’s no better classroom microphone for an impromptu karaoke session! And if you need a higher level of volume, you can also easily connect it to your PC!

Pros:

  • Excellent connectivity
  • Decent battery life

Cons:

  • Lower square feet coverage

Portable Voice Amplifier SHIDU

The Shidu mini PA system pretty much represents the most average — but still decent — device for anyone looking forward to talking to any kind of medium-sized gathering of people, including classrooms! With it, you get 10W of output power — along with three different colors to choose from; ladies being especially appreciative of the cute pink hue. 

Now, this is one of the smaller options you’ll find here, but it does put out a lot of great sound. And it’s quite clear as well — though ambient noise has turned out to be a bit of a problem. Still, it functions as an awesome voice amplifier, and you won’t have to tarnish your voice a lot when you speak to your class through the mic. 

The battery power definitely does a good job, propping you up for 12 hours of uninterrupted use. And even when you run out of juice, it won’t take more than three hours to fully recharge! Plus, it comes with a built-in music player, allowing you to enhance your classes with the best possible multimedia presentation. 

People have even used it for smaller lecture halls, along with large classrooms — it covers 5,000 square feet, which isn’t a lot but it’s still more than enough for most guest speakers or teachers. 

The only issues with it are that it doesn’t do a great job eliminating ambient noise, and thus you can’t really use it for outdoor events. Luckily, there are plenty of other wireless microphone on our list here that don’t have similar troubles — so if outdoor classes are important to you, there are always alternatives! 

Pros: 

  • Quite portable due to small size
  • Great battery life

Cons:

  • Bad ambient noise reduction
  • Not great for outdoor events

SHIDU Bluetooth Voice Amplifier

Compared to the last wireless microphone we’ve talked about, this one is practically its polar opposite — in fact, Shidu Voice Amplifier’s main purpose is outdoor use! This portable amplification system is fully waterproof, ensuring that nothing bad can happen to it on any nature outing. 

Also, it has a power capacity of 18; definitely hefty enough when it comes to portable PA systems. If you’re a teacher that needs to be heard during sporting events or swimming lessons, or really at any other kind of outdoor venue — you can use this device to get your point across without hurting your throat. Plus, if any rain happens to fall, you can still use the Shidu amplifier without any issues.

Unlike most other voice amplifiers we’ve reviewed here, it has a decent range of options when it comes to recording your voice — from USB drives to micro SD cards, all of the mainstream choices are present. Of course, the only downside here is that it’s a bit of an overkill for a classroom microphone.

Still, you may find it comfortable to use even in indoor conditions; the headset found with the amplifier is fully adjustable, so you don’t have to worry about head or neck pain. And it has an excellent span of Bluetooth connectivity! 

If you want to take your class on a field trip and still be able to maintain direct communication through your booming voice — this is a great addition to your set of school accessories. Plus, the fact that it’s waterproof means you won’t have to worry about anything happening to it while you’re outside. 

Tips for Picking the Right Microphone

Now that we’ve examined what the finest picks in this category are — we’re going to explore some of the factors that we’ve taken into account while making our choices. If you want to pick among different wireless mics on your own, keep these in mind as well.

Strong Battery

Your first factor should be the length of a microphone’s battery life. There are some excellent devices out there, but they have to be charged each couple of hours. That’s not something you want to do. Also, there are mics that are only supposed to be charged once their battery completely drains out. Obviously, there are models with 15 hours of battery life — and there are models that only give you a couple of hours. As a music teacher, for instance; you would need the model with the bigger battery — one that you’d only charge overnight.

Make Sure it’s Loud Enough

The point of a voice amplifier is to let people in the back of the classroom hear what you’re saying; even if you’re speaking normally, without raising your voice. So, while picking the best wireless microphones and sound amplifiers — make sure that they cover enough ground. There are heftier models that can even be used outdoors; though most classrooms can make do with lower-volume models.

Ease of Use

When you’re looking for this type of hardware, ease of use should be one of your primary concerns. For a classroom, a portable device is a necessity; that’s why all of the ones that we’ve reviewed here are easy to carry around. Sure, you may be just standing behind a lectern and speaking; in that case, any stationary sound system would be enough. However, as we’ve already mentioned; plenty of people move around while communicating with their students. That’s why battery-powered devices are better for this type of hardware.

Tips on Using a Voice Amplifier

The way that you’ll be using your wireless microphone and voice amplifier is important; it determines what kind of device you’ll be purchasing as well. For example — people like giving outdoor lectures might find themselves looking for a device that’s waterproof. That would eliminate worries about rain or air humidity.

Of course, you also need to consider comfort as a factor. You won’t want to use an amplifier that’s not hands-free and comfortable while carrying around your neck or waist.

What microphones do teachers use?

As you can see, we’ve provided you with a wide variety of choices when it comes to the best classroom microphones. Of course, for a range of reasons, some of these are more popular with the average teacher than others. 

While it may not be our top pick, we’ve noticed that the Zoweetek amplifier is definitely popular among classroom speakers; while it doesn’t provide the best sound quality, it’s combination of portability and a small price means that all teachers can afford it — even if their school doesn’t want to pay for this kind of equipment. 

How do I pick the right microphone for my voice?

Now, this is a tricky question even for professional musicians — let alone school teachers. However, luckily, you probably won’t have to sing in the classroom; which is why we recommend thinking about your priorities while picking a microphone. Ideally, you want something that provides enough vocal clarity — and apart from that, ease of use.

A classroom can be a hectic place, and you don’t really have time to spend precious minutes on setting up a complex audio system. Instead, you just want the ability to plug it in and play — while experiencing the least possible amount of technical issues. So, if you’re choosing between a couple of different microphones and all other factors are pretty much equal — go with the one that’s easier to use! 

What is the best microphone for online teaching?

In the past two years, online teaching has practically exploded — even though the practice was widely established before the COVID-19 pandemic too, and its popularity was slowly rising. Still, considering this, you might want to invest into a microphone for online teaching as well. Naturally, this is a completely different ballgame compared to a classroom microphone. 

Here, you don’t have to think about outdoor conditions or the square footage that you’re covering — the emphasis here is on reduction of background noise (from your household) and general quality of audio. Of course, you can also use built-in microphones that come with webcams — but their distance from your mouth means that you’ll usually get horrific background noise, so we recommend getting an external one. 

Wrapping Up

As you can see, there are plenty of different voice amplifiers that you can buy; with different sound quality, connectivity, and other features. If you’re going to get a more expensive model such as the Sennheiser, we definitely recommend taking a long look at the instruction booklet that comes with it. Otherwise, a simpler model like the Giecy one might be more your speed.
