A wireless omnidirectional microphone refers to a kind of mic that picks up sound from all directions and transfers wirelessly. Since it has a big influence on the audio's clarity and quality, it is essential while shooting videos. To assist you in selecting the ideal one for your needs, we will talk about its pros, cons, features, and make examples in real products. Knowing these aspects will help you select the finest one for adding excellent audio to your videos.

Wireless audio-recording pros
Wireless omnidirectional microphone is a popular choice in video filming due to its significant advantages. Here we list three pros to show you why you need the wireless audio recording: simple operation, international applicability, and reasonable cost.
Easy to use for free movements
To set up and use a wireless microphone, you don't require any technological expertise. Most wireless systems are plug-and-play, which means all you have to do to get started is switch on the receiver. The cordless design enables you to do free movements while speaking.
Budget-friendly price for YouTube beginners
The wireless microphone is a good choice for newbies who want to get started with YouTube or TikTok video recording. Because of its increasing technology and low price, it can allow you to get a microphone with good enough sound quality in the same budget range of product options.
Worldwide compliance and compatibility
The 2.4 GHz wireless omnidirectional microphone is in high demand as it may be used without a license in any country. You will note that various countries have different standards and that not all countries have synchronized their transmissions if you use UHF frequency ranges. 2.4 GHz mic devices protect you from all the regulatory uncertainties.
Wireless design cons
On the other hand, wireless microphone for recording also faces many drawbacks that are not well solved at this stage, such as transmission instability and latency, limited channel output, and battery issue.
Possible disconnection and latency
If there are buildings, trees, or people between the transmitter and receiver, or if the transmission range is exceeded, the stable transmission of sound may be disrupted. In addition, there might be a delay between the signal's input and audio output, which is known as latency.
Inadequate channels for multiple speakers
Most of the camera-mount wireless omni lavalier microphone systems sold on the market today are either mono or dual channel. For three or more speakers, this may not be enough. Moman PhotoGears Store sells these two categories as well, with one exception that supports 3-channel recording and two-way communication - the SYNCO G3 wireless collar clip microphone.
Battery replacement or charging problems
The majority of wireless microphones run on batteries, which must be changed or recharged on a regular basis. Though it might only be a small annoyance, bear this in mind if you want to use the microphone for prolonged periods of time.
Wireless microphone key features
- Dual or multi-channel separation: Separate mute, transmission, and power switches are among the most sought-after characteristics of a wireless system. The transmitter and receiver are "locked on" to the same frequency when they are connecting with one another. Dual or multi-channel can ensure different separate transmitters record in their own tracks.
- Long-range transmission: A wireless omnidirectional tabletop microphone or lavalier mic can offer dependable range and extend the necessary range for interference-free audio recording. It greatly expands the movable range of speakers, which is ideal for online PE classes or on-the-road recording.
Example: Moman C1X dual channel wireless microphone for vlogging
Moman C1X wireless camera microphone delivers superior sound with DSP tech, which offers effective noise suppression in noisy environments. It works stunningly long up to 8 hours and it is packed with a 3-in-1 charging cable for powering the transmitters and receiver at the same time. For now it is on sale and only cost US$99 (Regular price US$119).

Omnidirectional pickup pattern pros
During all kinds of microphone polar patterns, why choose the wireless omnidirectional microphone? It provides four benefits for use: Reduced wind noise, less popping, low distortion, and flexible placement.
Effective in handling noisy wind
Every unidirectional microphone has extra apertures for air to enter, which are the back acoustic ports. Additionally, turbulence caused by wind traveling through the backports might produce wind noise. Because an Omni lacks backports, wind noise is reduced.
Less plosive and vibration sounds
The plosive "P", "T", and "B" noises that can happen when a talker gets too near to a unidirectional microphone is also caused by those backports. An omnidirectional microphone is far more resilient than a unidirectional one, providing clearer recording effects.
Low-frequency response for rich voice
Wireless omnidirectional microphones reduce ratios of gain to feedback, especially when it comes to lower or mid-frequency frequencies. Since low frequencies make up the majority of handling and vibration noise, an omni's proximity effect means less of this kind of noise.
Capture great audio no matter whether placed up or down
It functions regardless of orientation since it has equal acuity in all directions. With portable microphones, it is uncommon to use a microphone upside down, but with small clip-on lavalier microphones, it frequently happens.
Omnidirectional polar pattern cons
This type of mic also has its disadvantages compared to the directional ones: It may pick up Unwanted sound from the ambient and have no room isolation.
Unable to prevent undesired background noise and echo
Because the Omni mic doesn't concentrate on a specific instrument or sound, there is less accurate channel separation while recording, which refers to the ratio of direct to indirect sound.
No room isolation
It is not the best option for isolating a particular sound source, such as a speaker in a packed room or on a stage. Because an omnidirectional microphone picks up sound from all directions, channel separation may be less accurate than with a directional microphone. Thus, with an Omni, the direct-to-indirect sound ratio may become even less favorable if channel separation is desired.
Omnidirectional microphone's main features
- Sensitive to sounds from all directions: Wireless omnidirectional microphone for conference room evenly picks up sound from all directions. Therefore, it is perfect for capturing discussions or interviews where participants are speaking from different places around the microphone.
- Lack of proximity effect compared to the directional mics: The proximity effect is the phenomenon wherein low frequencies in a recording are amplified because of the microphone's near proximity. Bass frequencies are amplified the closer the microphone is to the source of the sound. The impact is a lack of microphones that are omnidirectional, which makes the sound flat and less rich than the directional ones.
Example: SYNCO P1L omnidirectional lavalier microphone for iPhone
SYNCO P1L is an omnidirectional wireless microphone for cellphone with high-clarity sound and long-distance transmission of 150-meter (LOS). It is compact and versatile with a budget price of US$49 (Regular US$69). Due to the frequency response of 20Hz-20KHz and -26dB sensitivity, P1L can offer you pure and rich sound to promote the audio quality of your videos.
