Wireless microphone for speaking: Four basics to know

Using wireless microphone for speaking is a good choice. It enables you to move around freely while ensuring that your audience can easily hear you. It does away with the need for cables and wires, which can be clumsy and interfere with presentations. In this article, we will explore four basics of it to help you better understand its use in speaking, presentation, and other events.

What are public speaking wireless microphone systems?

A wireless microphone system consists of the following three parts:

  • Microphone
  • Transmitter
  • Receiver

The system's microphone functions just like a standard microphone. It performs the function of transducers, converting mechanical and acoustic wave energy (sound) into electrical energy (audio signals).

The audio signal produced by the wireless microphone is transmitted by the transmitter over specific radio frequency. This exact radio frequency, and hence the audio signal, is received by the receiver.

The wireless microphone and transmitter are free to move around without being tethered to anything. The receiver is usually placed near an audio console.

What are wireless microphone types of microphones for speaking?

Wireless microphones come in a variety of sizes, shapes, and styles. Here are there commonly used types that you can see in speech and suchlike events.

Wireless lapel microphone for public speaking

This wireless microphone for speaking is tiny and inconspicuous device that is hooked into the subject's clothes. It has a high signal-to-noise ratio because of its near closeness to the mouth. It also solves many of the problems associated with producing high audio quality with shotgun or on-camera mic placement.

Lapel mic is connected to a transmitter pack, which is often worn on the subject’s belt. There is also clip-on transmitter that has a mic built into it, so you can directly clip it on the clothes and talk to it. This eliminates the trouble of arranging the cable of the external lav mic.

Wireless headset microphone for speaking

A headset microphone is designed with a boom arm that stretches across the cheek. It can be placed very near to the sound source, which is the speaker's lips. Ambient noise is substantially decreased with only an inch or two between the mic and the lips, resulting in crisper audio.


During live presentations, it's usual practice to amplify the speaker's voice using a handheld microphone. It is often used in stand-up comedy, participatory presentations that involve the audience, and huge presentations (even if merely as a backup for lavalier or headset mics). The flexibility allows for easy passing between speakers and attendees.

What are the benefits of using handsfree wireless microphone for public speaking?

When giving a speech in front of an audience, using a hands-free microphone is a great method to make sure that everyone can hear you clearly and with confidence in any size venue. You can concentrate on giving a compelling speech without having to worry about how you're holding the device or if it's too close or distant from your mouth. They often offer better sound quality than standard handheld microphones and are made to operate well in big spaces like auditoriums or lecture halls.

In order to ensure that your audience receives only your message without any interruptions, many hands-free microphones also have added capabilities like noise cancellation and echo reduction.

How to choose the best wireless microphone for speaking?

There are several factors to take into account when choosing a wireless microphone for public speaking.

Operating Range

A wireless microphone's operational range is simply the distance from the receiver at which the microphone will continue to work.

The audio console is normally placed on one side of the stage for most presentation events. You may even be directly in front of the event stage in certain situations. A 100-foot working range should be sufficient for most small to medium-sized presenting occasions. As a general guideline, choose a microphone with double the range that you require!

The SYNCO G2 Pro, for example, is a good choice with a long working distance. It adopts the upgraded Syncoder™ 4.0 encrypted transmission algorithm to ensure clean and stable audio transmission within the LOS 656ft distance. When there are obstacles between the transmitter and receiver, the distance is 164ft.


Another thing to consider while narrowing down your microphone options is the features.

If you're a pro, you'll probably look at a lot of features before making a decision (and if that's the case, you might not even need this post).
But if you're like me and just want a reliable wireless microphone system for speakers without getting bogged down in the technicalities, here are some fundamental features to look for:

  • The number of microphones that can be used with a single receiver. This is useful if you need more than one speaker for a presentation.
  • Separate On/Off and Mute Switches. Look for a microphone with a separate on/off switch as well as a mute switch. This will save you money on operating costs because the batteries will not discharge as quickly.
  • Backlit mic display. You do not need to use a microphone with a display. However, if you do, make sure it is backlit. Otherwise, the additional expense of the mic display may not be justified because readings are difficult to see in low light.


The last point I'd want to bring out is the price. In fact, this may have been one of the first things you considered before exploring options.

A wireless microphone for speaking will cost you anything from $100 to $750 or more! Some of the more expensive microphones typically have really professional features that you may not require for presentations or events. Therefore, decide your budget and choose the wireless microphone for speaking that is suited to your needs.
