Voice Amplifier Buying Guide For Teachers

When it comes to finding the best voice amplifier for teachers, there are a few things you need to consider before making your purchase. The most crucial factor is the tone of your voice — you want something that will amplify your voice without making it sound too harsh or artificial. You should also consider how often you’ll be using the amplifier and what type of classroom environment you teach in.

Sound Quality

What type of voice amplifier do you prefer? Check its sound quality level, sound power, and other sound-related factors while looking into your product. You want your students to be able to clearly hear what you’re saying, even in a crowded classroom. Amazon review sections are especially helpful for gauging users’ experiences with sound quality. 

Classroom Size

The best voice amplifiers will work in any classroom size, but if you’re looking for something specifically designed to be used in a large auditorium-like setting, then make sure it has an extended range and high power output. Also, if you are frequently giving presentations outdoors, then take into account that even a small outdoor space generates much more noise than an indoor one because of factors such as wind and construction. 

Sound Clarity

Sound clarity matters when choosing your voice amplifier. This determines how clearly others hear what you’re saying, which is essential during lectures where students need to fully comprehend every word. Clarity is different from quality because you need your voice to be clear and sound natural, not just loud. 

Build Quality and Material

Most voice amplifiers are made of plastic, but some models use better-quality materials like aluminum that are more durable and resistant to damage over time. If you’re looking for something long-lasting, then look out for these features when choosing your device!

Battery Life

How long does a voice amplifier last on one charge? If you’re using it for only an hour or two at most, then there’s no need to worry about this feature. However, if you want something that will last all day while you teach, then you should make sure to check out not only the battery life but also the time it takes to recharge. Look into what type of batteries are used in these devices as well, because some may require specific chargers while others can be charged via USB cables like regular smartphones (or even car adapters).


Portable amplifiers are great because they’re easy to bring from one classroom to another. This makes them ideal for teachers who travel between schools during the day or those who only need to use this device occasionally rather than daily. If you’re someone who doesn’t move around a lot, or if your school has already provided a stationary amplifier for the classroom, then this might not be as important to you (although it never hurts to have an extra one on hand just in case).


Let’s face it, we all want something that looks nice and won’t stick out like a sore thumb sitting on our desk. Amplifiers come in all shapes and sizes, so there are plenty of designs to choose from; however, make sure the size is appropriate for where you plan to put it! Some teachers prefer smaller amplifiers that don’t take up too much space on their crowded desks, while others might want something more sophisticated with more bells and whistles included.


If you’re looking for a voice amplifier with Bluetooth connectivity, make sure it’s compatible with all of your devices (e.g., iPhone, iPad, and Android). This way, students can use their own smartphone tablets instead of being stuck listening through the speaker on one phone without any customization options like volume control, etc. You should specifically check for what type of audio files the amplifier can support as well (e.g., MP3, WMA, etc.) to ensure compatibility with all of your devices.

Power Output

The power output of a voice amplifier is an essential factor to consider when choosing one for your classroom. It determines how strong the sound will be, which means it can have a significant impact on student learning experiences. If they can’t hear what their teacher has said, then there’s no point in having them listen at all!


Voice amplifiers come with many features that make teaching more accessible and fun. Some include Bluetooth connectivity, so you don’t need any wires or cords. Some models also allow students to connect their own devices such as smartphones or tablets via a USB port. This gives them access to music videos, podcasts, games, and more while they listen attentively! In contrast, others offer multiple channels so teachers can take turns talking without interrupting each other during lessons (or even class discussions).

Headphone Jack

A headphone jack is great for students who want some privacy during lessons and those who need assistance to hear what’s being said better than everyone else. It’s also useful for teachers since they can use headphones too! You should check the compatibility of your preferred headset and/or earphones so that you do not need to look for a separate adapter.


Some voice amplifiers can also be used for other purposes such as public speaking or presentations. If you think you might want to use your amplifier for more than just teaching, then this is an important feature to consider.

Frequency Response

This is the range of sound frequencies that the amplifier can produce, and it’s something you might want to consider if you’re looking for an amplifier specifically for music playback. Most voice amplifiers have a frequency response of 100Hz-15kHz, which is great for spoken word but not so good for listening to music.


This is an essential feature if you often use your voice amplifier outside or in moist environments. It’s not always easy to keep electronics dry, so it’s nice that some manufacturers have taken this into account with their products.


The price of a voice amplifier is also important because teachers need something that won’t break the bank but still has all the necessary functions such as volume control, range, and output level settings. There are so many different models to choose from when looking at amplifiers for classroom use.


When purchasing the best voice amplifier for teachers, there are many factors to consider. The most important features include the battery life, portability, power output, and extra features offered. Price is also an important consideration, especially when looking at models that offer all the necessary features for a great classroom experience. 

So, what’s the best voice amplifier for teachers? The answer to that question really depends on individual needs and preferences! We’ve given you several fantastic options to choose from that will surely improve your students’ classroom experience.
