Zoweetek ZW-S615

Impressive Range

Voice amplifiers can often vary by quite a bit in regards to the maximum range in which they can be used. Some voice amplifiers are only meant to help one's voice be heard to a small group of people who are relatively close to the speaker, whereas others are made to make your voice clear to a large audience in a large auditorium. The Zoweetek ZW-S615 Voice Amplifier, thanks to its large range of up to 10,000 square feet, is definitely one of the latter. This device has been made to help people of all types project their voices over a large distance, whether they are in a large enclosed area or out in a field. Wherever it is, those you are addressing will be able to hear you loud and clear.

First things first, the battery life of this device definitely deserves a mention. Despite its high power, this voice amplifier contains a built-in 1800 mAh rechargeable battery that can last for up to 15 hours of use. What this means for you is that you can easily go through a full day of using the device without needing to recharge it before the day is over. In fact, the battery life may be enough to last several days before needing a recharge, depending on how much you are using it and the volume settings of the speaker.

Review of Zoweetek ZW-S615 Voice Amplifier

Powerful Speaker

Speaking of the device's speaker, this model features a high power ultra-light magnetic inner trumpet that helps deliver crystal clear sound at powerful levels. The speaker has a total power output of 10 W, so you know you're getting a device that is more than powerful enough to meet your needs. The kit also includes 2 microphones on the headset: a wireless UHF and a wired microphone. Moreover, the first is distinguished by good resistance to interference, and the wireless headset itself also contains a rechargeable battery that should last for between 3 to 5 hours. If the wireless model's battery life doesn't quite meet your needs, there should be no problem with swapping it out for the wired microphone.

One nifty feature about this device is that it can broadcast more than just your voice. Built-in to the speaker is a Micro SD card reader as well as a USB port that lets you connect storage containing audio files that you can easily play. In fact, this speaker has pretty good audio quality for music, so the device can actually double as a music player for parties or other gatherings. There is even a 3.5mm aux jack for connecting another audio source if you need to do so. All of these features added up together make this device one of the best and most flexible audio amplifiers out there.

McCuinfinite Portable

Great Teacher's Aide

If you are a teacher by profession, and often teach in front of a large class with students who may have trouble hearing your voice clearly, then a voice amplifier is something that you need. Of course, such a device would need to be lightweight so it doesn't become tiresome to wear or hold it all day, yet with enough battery power to allow you to use it through a full working day without the need to recharge the device. With these requirements in mind, you should definitely take a close look at the McCuinfinite Portable Voice Amplifier, as it not only meets these requirements but easily surpasses them.

A first glance at this unit will quickly reveal that it doesn't look like many of the other voice amplifiers on the market. Instead of an intimidating looking black box, this voice amplifier comes with a white outer casing featuring rounded edges that will look nice and friendly to anyone. On top of that, the device isn't overly heavy, coming in at less than half a pound, although it should be noted that this is the heaviest of the devices on our list. Despite that, though, you won't be at all uncomfortable by wearing it on your body for extended periods of time. When you're finished with using the device for the day, you can stow it away in the convenient carrying case that comes with the unit.

Review of McCuinfinite Portable Voice Amplifie

Long Lasting Battery

What will really catch the attention of most people who are looking at this device, though, is the incredible battery life. This voice amplifier comes with a built-in 2000 mAh rechargeable battery that can last for up to 40 hours of continuous use. This is indeed quite impressive, considering that this is about enough battery life to get you through an entire week of full shifts! Needless to say, none of the other models on our list even come close to matching this, so if the battery life is the most important aspect for you, then this is the voice amplifier that you need.

The impressive battery life isn't all that this device has going for it. The speaker of this device is 10 W and is strong enough to make your voice heard clearly throughout a large classroom or a small auditorium. A headset with a microphone is also included which gives you clear voice reproduction. It should be noted, though, that the microphone is highly directional and is very picky about picking up your voice clearly at anything but the optimal angle, so you may need to spend some time adjusting the fit of the headset to ensure that the microphone is at the proper angle. Besides this minor issue, we are sure that most teachers or others who require a good voice amplifier with great battery life will find this to be exactly what they need.

WinBridge WB001

Lightweight Amplifier

One of the problems with some of the portable voice amplifiers available on the market is that they are often not very comfortable to wear or to hold. With most voice amplifiers, using one for just a few minutes isn't very difficult, but when it is necessary to use for long periods of time, the device always seems to become heavier and heavier. This is especially true for many of the voice amplifiers that attach to a belt or are held by a waistband or lanyard, and they are also often cumbersome when having to move around often, which is very inconvenient for many people who can benefit from such a device.

The WinBridge WB001 Ultralight Portable Voice Amplifier is an ultra lightweight voice amplifier that is much lighter and easier to use for extended periods than most of its competition. Weighing only 4.8 ounces, this amplifier provides a very comfortable wearing experience while also excelling at providing a good amount of voice amplification. Even after wearing or holding it for extended periods, the device is so lightweight that most people often forget that they are wearing it, and the lightweight also makes it much more convenient to use when making constant movements. This helps make it an ideal voice amplifier for yoga and fitness instructors, or even performers.

Review of WinBridge WB001 Ultralight Portable Voice Amplifier

Great Feature Set

The extreme portability of this voice amplifier is far from the only positive. Included with the voice amplifier itself are many of the advanced features that many people like having in such devices, including the ability to quickly and easily play audio clips with just the touch of a button. The device supports both SD cards and USB drives, which allows your voice amplifier access to hours of pre-recorded audio clips. This device provides 5 Watts of power for your voice amplification, which is plenty sufficient for allowing those even in the back of a large auditorium or classroom to hear you perfectly clear.

The voice amplifier comes with a built-in rechargeable battery, which can provide between 5 to 8 hours of voice amplification, depending on the volume used. Generally, the higher the volume, the more battery power that is required, although the voice projection at just half of the total volume is usually sufficient for all cases. Also included with the voice amplifier are an attached microphone with a flexible gooseneck, a USB cable that allows you to charge it while attached to a computer or a standard mobile device USB charger, and a waistband. This complete kit provides a great package for anyone who needs a high-quality, lightweight voice amplifier.

MAONO AU-C03

Ultra-Portable PA System

Many people in professional presentation roles, as well as performers, know all about PA systems. For many years, PA systems were what a person needed in order to address a large group of people spread out over a large area. PA systems have been quite expensive and not at all portable, requiring a lot of space and time to set up properly. Furthermore, they can often be complex creatures, which means that any problems that happen with them can take a long time to track down and fix.

However, the problems of PA systems are quickly being relegated to the past, thanks to the MAONO AU-C03 Mini Voice Amplifier with USB Charging. This ultra-portable PA system packs everything that was needed in a traditional PA system into a tiny, pocket-sized box. With the included speaker, this miniature PA system can be used to address the same sized groups of people that older systems were used for. This means that now anyone can carry their own PA system anywhere, even in their pocket if so desired. This kind of portability in a PA system is a dream come true for those who rely on them, especially those who have to do a lot of traveling, or those with physical demands such as walking or other activities while speaking.

Review of MAONO AU-C03 Mini Voice Amplifier with USB Charging

Great Features Included

With the flexibility provided by this voice booster, this alone makes it a great value. However, there are plenty of other features included that should make this voice amplifier stand above many others. The voice amplifier includes a microphone headset that uses a unidirectional microphone, which means that your voice is carried through the speakers loud and in high quality, without any background noise added. The dual voice coil 360 stereo speaker provides a loud audio signal in all directions, so people standing off to the side can hear instead of the sound only going to those directly in front. The device uses an internal battery that can provide up to 10 hours of working time, and can be charged quickly through the micro USB port.

Other features included in this voice amplifier are support for audio playback from a TF card as well as an auxiliary input for external devices. It even allows for simultaneous voice amplification during audio playback, which means you can easily use it as a portable DJ station or even as a karaoke system. All of these included features packed into such a small device makes this voice amplifier one of the best devices of its kind that you can find on the market.

WinBridge 378N

Multifunctional Amplifier

Voice amplifiers are almost always made for a singular purpose: to amplify and project the user's voice so it can be heard clearly throughout a large area. All of the voice amplifiers that we have featured on this list will definitely do this quite well, but what if you need a device with a bit more functionality than just that? If that's the case, then you should consider the WinBridge 378N Voice Amplifier. This model is not only well-suited to working as a voice amplifier, it also contains some other very useful features that really add to the overall usefulness of the device.

The appearance of this device doesn't cause any misunderstandings about what it is meant to do, but a closer inspection will show you that it definitely does have some capabilities that simply aren't found on most other models. For one, the device has an LCD screen that gives you information about the mode it is set to, as well as the amount of battery life remaining and the FM station that it is currently tuned into, among other things. Below the display are buttons that let you control the various aspects of the device, and a volume knob is located on the corner of the unit that lets you easily set the volume to the optimal level.

Review of WinBridge 378N Voice Amplifier

Play Your Favorite Tunes

You probably noticed that we mentioned that it has an FM tuner built-in. This is one of the features that you typically won't find in most other voice amplifiers, and it can really come in handy. You can tune the device just like with any other portable radio, setting it to loudly play your favorite radio stations to the delight of those around you. Of course, this unit isn't just limited to playing music from your favorite FM stations. Also built-in is an SD card reader as well as a USB port that let you load up either of these storage devices with music and play them through the device's speaker. So, not only does this unit work to project your voice, it can also be a portable jukebox for many different occasions.

Unfortunately, not everything is roses with this particular unit. For one, the battery life will only last you for between 5 to 8 hours, making it much shorter than all of the other models on this list. Also, the unit, while not very heavy, is a bit bulky and may be awkward to wear for long periods of time. Thankfully, though, it does come with a handy shoulder strap that makes it easy to wear without getting in your way. Back to a positive note, the headset with included microphone is comfortable to wear, with the mic picking up your voice quite clearly. In the end, the additional features of this device make it a prime pick for those who want a model that does more than just amplify your voice.

What Is a Voice Amplifier?

A voice amplifier is an electronic device that is meant to provide amplification for a person's voice. They are similar to a PA (public address) system in that they pick up the sound waves from a person's voice, but provide amplification of the audio within its own self-contained unit instead of routing the signal to external amplifiers. The voice amplifier device usually contains a microphone which connects to a small electronic box that is worn by the person, and which provides the amplification of the audio.

Voice amplifier devices have become widespread within recent years, thanks to the advancement of technology, which has allowed the shrinking of the size of the circuits and electronics necessary for amplifying an audio signal. This allows the device to be small and portable, with most models fit to be worn by a person, yet powerful enough to amplify a voice over a large area. They have become quite popular to use for many different purposes, including teaching, presentations, public announcements, and even for singing performances. These small devices are also very affordable, which opens up the possibilities for their use by anyone.

What Features to Compare

Most voice amplifiers serve the same purpose - to allow the amplification of a voice to be easily heard by many people within a large area. However, many of the latest voice amplifiers actually have many other abilities, including the ability to save and playback audio, save audio to external storage, link up with other A/V equipment, and more. If you are simply looking for a device to provide voice amplification, then most models should serve that purpose quite well. On the other hand, it's best to be aware of the different capabilities of each model, and to know what to look for when choosing the right device for your needs. Here are a few of the common characteristics that one should be aware of before purchasing a voice amplifier.

Battery life - Since most portable voice amplifiers use battery power, the total length of battery life of the device is one of the most important things to be aware of. Voice amplifiers generally support a long battery life, but it is always best to check to see if the maximum battery life of the device you want to purchase will be adequate for your needs.

Audio Recording Capabilities - One of the features that has become popular on a lot of recent models of voice amplifiers is the ability to record audio. When making a presentation or delivering some kind of performance, being able to record the audio can have a tremendous number of benefits for both the presenter and the audience. Instead of having to rely on expensive recording equipment to do the job, having this capability built-in can save a lot of time and money.

Easy Audio Playback - Along with the recording capabilities included with many voice amplifiers, being able to quickly and easily play back recorded or pre-recorded audio clips can add a huge impact on any presentation or performance. If this is a capability that you desire, then check to make sure that any voice amplifier you are considering for purchase includes it.

Audio Storage Capacity - For voice amplifiers that have the ability to record and play back audio, the amount of included storage will, of course, be a concern. Some voice amplifiers do include some built-in storage, while most instead only provide support for external storage formats, such as SD cards. If you desire a voice amplifier with this capability, you should check any model that you are considering for purchase to see what kind of data storage is included or supported.

Comfort and Ease of Use - Most of the voice amplifiers available are highly portable and can be easily worn. However, not all of them will be comfortable to wear or even very easy to use. For any such device that will be worn for an extended period of time, it is best to make sure that it can be both comfortable to wear and easy to use for any length of time that it will be in use.

Keys to Addressing a Group of People

Finding the right voice amplifier is not only just the first step in preparing to address a large group of people, it is also the easiest step. A voice amplifier is just a tool used to amplify your voice, and it does nothing to help people get over such things as stage fright or nervousness. Preparing a speech can be a bit nerve-wracking, but actually giving it can be even worse for some people. If you fall into this category, then fear not - you are definitely not the first person to go through this experience. Every day, there are thousands of people who are doing the same thing that you will do, and you can bet that most if not all of them are experiencing the same kind of anxiety about public speaking.

Public speaking really isn't much different than speaking with a large group of friends or family. Sure, most of the people you probably don't know as well, but it's still the same thing. Here are a few points to keep in mind about addressing a large group of people that should help you overcome your fears or worries and help lead to a successful speaking engagement.

Speak As If to Just One Person

When looking out at a crowd of people who all have their attention focused on you, it can be a daunting experience, especially if this isn't something that you haven't done before. Most people have probably heard the advice before about imagining that all of the people in the crowd are in their underwear. Really, thinking of such a thing doesn't help anyone, and it can even make some people feel even more nervous. Instead, just imagine there is one person that you are speaking to face to face. Speaking to a large group really isn't so different than just speaking to a single person, after all.

Slow Down Your Speech

It's a habit for many people who are feeling nervous to speak very quickly, often stumbling over large words or having other such ticks in their speech. If this describes you, then just take a moment before speaking to take a deep breath, calm yourself, and speak slowly. Speaking is not a race, after all. Speaking slowly will allow your body to also calm itself down, and there will be much less chance of stumbling over words during your speech.

Look and Act Confident

This is probably one of the harder points for many people to grasp, but it's also one of the most important for public speaking. People are naturally drawn to confidence, and many of the greatest public speakers exhibit confidence in spades. The content of your speech won't matter so much just as long as you are speaking and acting confident. This can be quite difficult for some people who struggle with confidence, but once you learn how to at least act the part, you will soon find yourself being the part.

Be Yourself!

This last part goes hand-in-hand with the previous point. Don't feel the need to act like someone else while speaking to a crowd. People aren't expecting to listen to someone else, they are expecting to listen to you. Just be yourself, and don't feel the need to act like someone else. Feeling confident in yourself should automatically lead to you just acting in your own natural way, and people aren't going to be disappointed if this is how you conduct your speech.

Public speaking can certainly be a daunting task for many people, but keeping these points in mind should help lead you to delivering a natural and successful speech that is enjoyed by all.

FAQ:

Q: Are voice amplifiers expensive?

A: This will largely depend on a person's definition of expensive. However, most portable voice amplifiers are very affordable, and far more so than a traditional PA system. Even those on a very limited budget should be able to afford a good quality voice amplifier.

Q: What are the basic parts of a voice amplifier?

A: Although the specific features of many voice amplifiers can vary greatly, almost all of them consist of some basic parts, with the two main ones being a microphone, a powered amplifier, and a speaker. They all also tend to have controls to adjust the volume. They also all have some method of carrying or wearing the amplifier, as many include a waistband or lanyard.

Q: In what situations should a person use a voice amplifier?

A: There are a multitude of situations in which a voice amplifier can be used. Many teachers, professors, fitness instructors, performers, and even people with naturally weak voices can all benefit from using a voice amplifier, especially when addressing a large group of people in a large area.

Q: Are all voice amplifiers rechargeable, or do any of them rely on disposable batteries?

A: Almost all modern voice amplifiers include rechargeable batteries, although there are still some models that rely on disposable batteries. Even so, such models can still use rechargeable batteries, as many rechargeable batteries now come in the standard disposable battery sizes.

Q: What is the best method for carrying or wearing a portable voice amplifier?

A: The best method for carrying or wearing a voice amplifier is going to depend on a lot of different factors, and will also vary depending on each individual person. The most common ways of using portable voice amplifiers are by using a waistband, shoulder sling, or lanyard. Which way is the most convenient and most comfortable will be different for each individual person.

Q: Can most voice amplifiers use microphones that did not come with the amplifier?

A: This will mostly depend on the specific voice amplifier. However, most voice amplifiers use a standard microphone jack for connecting the microphone, which should allow any microphone that connects in this way to be used. Likewise, most voice amplifiers that use a wireless microphone have the microphone and amplifier pair together via Bluetooth, which means that most Bluetooth microphones should work with it. Regardless, it is best to check with the manufacturer of the voice amplifier to confirm if third-party microphones are supported.

Q: Can a voice amplifier be connected to other audio/visual equipment?

A: This is something that depends entirely on the voice amplifier. Most voice amplifiers do not support the output of audio. However, a large number of them do include inputs from multiple types of devices, either through USB or standard auxiliary jacks. If you need a voice amplifier that can connect to other devices, you should verify with the manufacturer whether or not it is possible with a specific model before buying one.
