Selection 1: Your Budget Range

This guide will recommend the appropriate voice amplifier according to consumer needs, the price of the voice amplifier is not set in stone, will change with the trade policy, Black Friday, and other holiday discounts, the usual price of the voice amplifier in the 50 U.S. dollars with 160 U.S. dollars price range changes, consumers can choose the most suitable for the use of the guide according to their spending power voice amplifier.

Selection 2: Number of Students

Consumers can choose the power of the voice amplifier according to the number of students in the classroom. The power of different voice amplifiers varies and so does the effect and quality of voice amplification.

So classroom users of different ages can choose the most suitable voice amplifier according to their teaching scenario and the number of students in the class.

For the number of students in kindergarten classrooms, our recommended voice amplifier is the voice amplifier with an output power of 5-10W. The reason for the recommendation is that the output power of the 5-10W voice amplifier is suitable for the number of students within 30-80 people. The number of kindergarten students is usually within this range, so this type of voice amplifier is the most suitable.

Depending on the number of students in elementary/secondary classrooms, we recommend 10-18W voice amplifiers for elementary/secondary teachers. This is because the output power of the 10-18W voice amplifier is suitable for the number of students 80-120. The number of students in elementary and middle school classrooms is generally within this range, so this type of voice amplifier is most appropriate.

For the number of students in university classrooms or outdoor teaching, we recommend university or outdoor teaching teachers use voice amplifiers of 20W or more because these high-powered voice amplifiers can make 180 people hear clearly.

Selection 3: The Amplifier Classroom Area

Before you buy a voice amplifier, you need to know the size of the classroom you are in. Because not all power voice amplifiers have the same voice amplification effect, the area of voice amplification is also different.

The amplified volume that can be picked up in a classroom is related to the output power of the voice amplifier, and the distance the sound is transmitted must also be considered. There are some other parameters to consider in the voice amplifier. Not all power voice amplifiers have the same parameters.

First of all, for the area of a kindergarten classroom, our recommended voice amplifier is an output power of 5-10W. The reason for the recommendation is that the voice amplifier with an output power of 5-10W is suitable for venues within 40 meters. The Kindergarten classroom site area is generally within this range, so this type of voice amplifier is the most suitable.

According to the area of the primary and secondary school classrooms, we recommend a 10-18W power amplifier. Because this type of voice amplifier is applicable to the venue area within 80 meters, and the classroom area of primary and secondary schools are generally within this range. So this type of power voice amplifier is the most suitable.

According to the size of the university or outdoor classroom area, we recommend the use of 20W and 20W or more voice amplifiers for university or outdoor classroom users. This is because these high-power voice amplifiers have a long sound transmission distance of up to 1000 square feet.

Selection 4: Wired or Wireless Voice Amplifier

For classroom users who want to purchase wired or wireless voice amplifiers, we have listed the advantages of each and the user application. For classroom users who cannot decide whether to choose wired or wireless voice amplifiers for use in the classroom, you can check below:

Advantages of wired voice amplifiers:
1. Wired voice amplifier is lightweight, compact, and portable.
2. Operation is straightforward, even if you could without needing the manual. Just plug and play.
3. Sound clear, easy to use, and you can adjust the belt and volume easily

Applications where wired voice amplifiers are not easily used:

2. Wireless voice amplifier comes with a wireless microphone that has a great future for controlling the volume.
3. The max sound can cover about 10000 sq. ft (1000 ㎡), loud enough to cover a big room.

Applications where wired voice amplifiers are not easily used:
1. Wireless microphone is easy to run out of power needs frequent charging, and it is tedious to use.
2. Microphone pairing voice amplifiers often can not be paired, UHF pairing is more difficult.
3. The voice amplifier with a long time, the propagation distance will be relatively short.

Selection 5: The Voice Amplifier Power Requirements

We recommend different models of voice amplifiers to our customers based on the time the teacher uses the voice amplifier in the classroom and the length of time it takes to charge the voice amplifier, depending on the teacher’s class time and curriculum.

If the classroom user uses the voice amplifier for more than 5 hours a day continuously, we recommend this model, which has a large battery with nearly 20 hours of usage endurance, comes with a wired microphone that does not require additional charging, and has a fast-charging feature that takes 3 hours to fully charge, a feature that makes it ideal for continuous use by classroom users.

This fast-charging voice amplifier both Bluetooth and music playback functions can play music through Bluetooth devices, U disk, TF card, music class, dance class music playback time of about 10 hours, suitable for music teachers in the dance classroom use.

For teachers who need to use the voice amplifier teaching in the classroom all the time, we recommend a large battery wired voice amplifier, because the wireless microphone can generally only be used for a maximum of 5 hours continuously, and this voice amplifier does not need a wireless microphone, can be used continuously for more than 10 hours, continuous playback of music for about 10 hours, can meet the normal teaching time of teachers.

Selection 6: Voice Amplifier for Classroom Users with Face Mask

In the face of the Covid19 pandemic, teachers teaching in classrooms must now wear face masks, a situation that may result in teachers teaching in classrooms with lowered voices and students who may not hear them when they speak. We recommend that teachers use high-powered voice amplifiers.

High-powered voice amplifiers are the most appropriate aid when teaching and using a face mask at the same time. One of the most basic features of all these types of voice amplifiers is that the output power is 20W or more.

When using a 20-watt voice amplifier, voice amplification is very effective. The farthest distance it can reach is 1000 square feet. It allows 180 people to hear very clearly.

These types of voice amplifiers usually have Bluetooth capability. If a classroom user’s throat is not comfortable, she can record her session in advance. In the classroom, the Bluetooth device will play the audio from the voice amplifier.

For music classes, these types of voice amplifiers can be used as music players on their own.

Selection 7: Whether to Interact with Students in The Classroom

We recommend this voice amplifier with two microphones to consumers who need to interact with students and teachers in the classroom. Consumers choose whether or not to purchase this voice amplifier with two wireless microphones by whether or not they interact with students.

The most important feature of this voice amplifier is that it can be connected to two wireless microphones at the same time, so the teacher can use the wireless microphone to lecture in the classroom and ask questions to the students, and the students below can answer with the wireless microphone, which has a good effect on the interaction in the classroom.

The voice amplifier with two wireless microphones also has a Bluetooth function, which can play music through cell phones, computers, and other Bluetooth devices.

Students and teachers can interact by singing and reading aloud together through wireless microphones, and such behavior is very helpful for teaching. At the same time, the voice amplifier inserted into the U disk or TF card can also play music, without the need to use special Bluetooth devices.

If consumers need to interact with students in the classroom, they need to buy a voice amplifier with two wireless microphones, and if they do not need to interact with students in the classroom, they only need to buy a voice amplifier with one microphone.

Selection 8: Whether to Teach Outdoors or Not

For different usage scenarios, we recommend using different voice amplifiers. Teaching can be done indoors or outdoors in a classroom.

For indoor teaching, consumers need to choose the right voice amplifier by classroom size and the number of people. For outdoor teaching, the selection should consider the outdoor venue, weather, and other factors.

For outdoor teaching, we recommend the most drop-proof, waterproof, and dust-proof voice amplifier. When using this voice amplifier outdoors, you don’t have to worry about the impact of strenuous movement and sudden rain on the voice amplifier. This voice amplifier has more than 10 hours of voice amplification time, so you do not need to worry about battery life to use.

This voice amplifier is available in both wired and wireless models. You can choose from different models. Teachers can purchase the voice amplifier by the features it includes to match their teaching style.

This voice amplifier can also be used outdoors as a music player. For example, when a teacher is teaching in a fitness classroom or yoga classroom, it can play audio by simply inserting a USB drive. This voice amplifier can be of great help to teachers.

The music playback time can reach more than 8 hours. You can use the voice amplifier equipped with a handheld microphone or headphones, or both.

Selection 9: Live teaching in Offline and Online Classrooms

Due to the global new crown epidemic, classroom users are among those who face difficulties and challenges when teaching students. Sometimes, classes are either online or offline. If there is a useful gadget to assist classroom users during these times, they are voice amplifiers!

Voice amplifiers can assist teachers in the classroom in the following ways to teach in a new and normal way.

Speaking loud and clear
Voice amplifiers will assist teachers in delivering the teachings they want to discuss with their students with less effort. Instead of speaking loudly or manually amplifying their voices, the voice amplifier will do the work for them.

As a result, teachers will not strain themselves while lecturing because they can speak quietly while the voice amplifier will deliver a clear and loud message to the students.

Reduce your mental stress
One of the most formidable obstacles that teachers must overcome is stress. It’s impossible to avoid, especially when students don’t take in or understand what the teacher is saying, leading to a cascade of questions.

However, this can have an impact on their ability to teach in the future. Voice amplifiers reduce psychological stress because they present the lecture loud and clear to students, and teachers feel confident in all their efforts when discussing how well their students understood the lesson.

Learn, more efficiently
Teachers can deliver loud and clear lessons to students by utilizing voice amplifiers, which provide the highest audio quality to enhance learning. Students will be able to hear the information without any sound barriers, which are often caused by the low-quality audio output of some microphones on the teacher’s equipment.

Examples of this include those used in online classrooms, which will be established as the “new normal” model for schooling in a pandemic situation.

The presentation is similar to that in the classroom
Suppose the teacher prefers to use a chalkboard, whiteboard, charts, or any other teaching method. In this case, if the teacher has a chalkboard at home, a voice amplifier can be worn on the belt and a connected microphone used to discuss the lesson.

Because the voice amplifier is also equipped with Bluetooth, the teacher can use a wireless microphone. The teacher can pick between these two options depending on his or her preference.

Selection 10: Voice Amplifier for Dance Classrooms

If you are a dance teacher, you will need a voice amplifier and Bluetooth speaker to help you with dance classes in a dance classroom, because voice amplifiers are very practical.

If you are teaching a dance class in a small or medium-sized classroom, you can choose a wireless headset microphone so that you can dance freely while talking out loud.

The best voice amplifiers have multiple functions that can be used simultaneously. Let’s discuss the different features you can get from a WinBridge voice amplifier.

Bluetooth connectivity

When choosing the best voice amplifier, check all of its features such as wattage and connectivity range.

Battery and power life
A rechargeable device is more useful and economical than using disposable or rechargeable batteries. If you want a long-lasting voice enhancer device, choose one with a battery life of at least 5-8 hours or more.

WinBridge voice amplifiers have durable batteries, so you can use them for a longer period of time. Since most of the charging cables are USB ports, you have more options to get them recharged.
With a rechargeable battery, there are no more messy cords when you use it. Wireless gadgets are very convenient and even the charging cables are long enough to fit in a small case. They are very portable and you don’t need other adapters or cables to make them work.

Eliminate noise
A wireless speaker’s circuitry should be designed to minimize white noise and unwanted ambient sound so you have a wonderful and fulfilling listening experience It should filter and eliminate background interference so you don’t have to crank up the volume to hear the sound clearly.

For wireless headphones or microphones, active noise cancellation reduces excessive or unwanted noise because its structure provides a barrier to filtering high-frequency sound waves. In this way, noise is reduced by actively eliminating or filtering low-frequency sound waves.
