Have you ever tried using a wireless lavalier microphone? They look so sleek and trendy. Wireless microphones have revolutionized the audio industry, offering convenience and mobility without sacrificing sound quality. Using a separate wireless microphone transmitter, we can ensure that our microphone and mouth stay close together all the time, even when we're far away from the camera that's picking up the sound.

In this article, we will delve into the workings of wireless microphones, the various types available, and their differences, and provide insights into choosing the best wireless microphone for different needs.

How do wireless microphones work?

Wireless microphones transmit audio signals without the need for physical cables. They utilize radio frequency (RF) or digital transmission technologies to send audio from the microphone to a receiver unit. The receiver then outputs the audio signal via a USB connection to a computer or digital device (e.g. camera or smart phone). 

Wireless microphones work by using radio waves to transmit audio signals from the microphone to a receiver unit. Here’s a simple breakdown of the process:

1. Microphone (Transmitter)

The microphone itself has a built-in transmitter. Instead of sending signals through a cable, like traditional microphones, it converts sound waves (your voice, for example) into an electrical signal.

2. Radio Waves

The transmitter then converts this electrical signal into radio waves. These waves carry the audio signal through the air.

3. Receiver

The receiver unit, typically connected to a recording device or a sound system (like a camera or a mixing board), picks up these radio waves.

4. Conversion to Audio Signal 

The receiver then converts the radio waves back into an electrical audio signal, which is identical to the signal originally captured by the microphone.

5. Output

Finally, this audio signal is sent to speakers, recording devices, or broadcast equipment where it can be heard or recorded.

Wireless microphones use specific frequencies within the radio spectrum allocated for this purpose. They also include features to minimize interference and ensure clear, reliable transmission of audio signals over distances ranging from a few meters to several hundred feet, depending on the model and environmental conditions. This setup allows for freedom of movement and eliminates cable clutter, making them ideal for live performances, presentations, and content creation.

More expensive high-end microphones come with additional features like onboard recording. Onboard recording means that the microphone attached to our shirt can save an audio file on its built-in storage while also sending our voice to the camera's receiver hundreds of feet away. If there's any signal loss, we can replace the problematic sound using the audio file saved on the microphone's storage.

What are the different types of wireless microphones?

1. Handheld Wireless Microphones

These are traditional microphones with built-in transmitters. They offer simplicity and ease of use, commonly used in live performances and public speaking engagements.

2. Lavalier (Lapel) Wireless Microphones

Lavalier microphones are small, clip-on mics attached to clothing near the speaker's mouth. They provide hands-free operation, making them popular among presenters, actors, and broadcasters.

3. Headset Wireless Microphones

Headset microphones feature a small microphone capsule mounted on a headset worn around the head or over the ears. They offer hands-free operation with improved stability, suitable for active presenters and performers.

What are the differences between them?

  • Usage

Handheld microphones are versatile but require holding, while lavalier and headset microphones offer hands-free operation.

  • Portability

Lavalier and headset microphones are more compact and lightweight compared to handheld models.

  • Audio Quality

Handheld microphones often offer better sound quality due to larger microphone capsules, though lavalier and headset microphones can provide adequate audio for specific applications.

  • Range

Some wireless microphones have longer transmission ranges than others, important for larger venues or outdoor use.

Which is the best wireless microphone?

The best wireless microphone depends on the specific use or purpose:

  • For Performances

Handheld microphones like the Shure BLX24/SM58 Wireless System are popular due to their reliability and sound quality.

  • For Presentations

Lavalier microphones such as the Sennheiser EW 112P G4 are preferred for their discreetness and hands-free operation.

  • For Active Use

Headset microphones like the Audio-Technica System 10 ATW-1101/H92-TH provide stability and comfort during movement.

Consider factors like frequency range, battery life, and compatibility with existing equipment when choosing the best wireless microphone.
