Learn about wireless mic for mobile video recording: 2.4G VS Bluetooth

A wireless mic for mobile video recording is a device that specially works for smartphones and suchlike mobile devices to capture high quality sounds. It is usually portable, allows for free movement and clean frame. There are two commonly used types. One is 2.4 GHz wireless mic and the other is Bluetooth microphone. Today let’s learn about them.

Definition

These two varieties both belong to digital wireless microphone, a device that captures sound waves, converts and transmits them in the ways of digital signals. Sound is captured by dielectric wafers or thin film transducers. This allows for more compact structure, effective noise immunity, and more exact sound reproduction. But there is something different.

Bluetooth is a short-range wireless technology standard that uses UHF radio waves in the ISM bands to transfer data between fixed and mobile devices over short distances. It is usually handheld in the microphone market.

As for 2.4 GHz microphone, it captures sounds with a clip-on transmitter and makes signal transmission to receiver that can mount on the phone via Type-C or Lightning port. It comes in the type of lapel microphone wireless system in most cases.

Below is a complete review video of SYNCO P2L. In this video, You Tuber Trending Reviews made a thorough introduction and test on the specs and features with regard to sound quality, voice effects, recording mode, and transmission distance. Just check the video to see how the 2.4GHz wireless mic performs in video recording.

2.4G wireless VS Bluetooth: differences in microphone specifications

As wireless mics for mobile recording, what are their features? The followings offer more information about them.

Frequency range

2.4G wireless microphone transmits signals in frequency range from 2.402 GHz to 2.48 GHz, thus getting its name. And Bluetooth is based on 2.4G technology but different from it due to the different protocols and the fact that it is not free.

Sound quality

When we use a wireless mic for phone video recording, the most important thing to look in is sound quality. Usually the audio recorded by wireless microphone system at 2.4G is better than that captured by Bluetooth one. This is incredibly significant in video shooting.

Operation

2.4 GHz mics can sniff out where occupied frequencies are and are not due to the predictable positions of WiFi channels, and they’re also brilliant at talking with other mics and self-coordinating. You don’t need to worry about the interference when using this mobile microphone for wireless recording. Moreover, it is also easy to connect it to your smart phone. It consists of transmitter and receiver. Just plug the receiver in the charging port like USB-C or connect it via a cable and you can start the recording.

To use Bluetooth, you don’t need to be an expert in the field of technology. Furthermore, the mobile recording setup is pretty simple. There is no need to install any software or drivers in this case. In addition, the pairing procedure has been simplified. It’s as simple as turning on Bluetooth on both devices and making them discoverable. The devices will be instantaneously connected as long as they are within the coverage range.

Latency

Unlike wired lavalier microphone, it takes time for wireless mic for mobile video recording to transfer acoustic waves into digital signals, so latency does exist in the video making. And they work in different bandwidth, causing different latency.

When it comes to wireless phone microphone with Bluetooth connection, the delay can be significant. It can be as high as 150 milliseconds depending on your equipment you’re using! As is often the case, people are capable of noticing 25 milliseconds of audio lag, let alone the latency of 150 milliseconds. And 2.4G mic performs well owning to the installed powerful processing chip.

Distance

Bluetooth microphone is aimed at short-distance recording. This kind of connection has a maximum transmission range of 100 meters. It varies by the version and nature of the devices and most have the range of 30m. So you are supposed to use it with your device within the range or the connection will fail.

2.4 GHz wireless microphone outperforms in this aspect. They are able to use within long distance. In general, the distance is 150m in the line of sight and 50m when obstacles exist. It is a perfect wireless mic for iPhone video recording to have shooting with free movement.

Compliance

In the same frequency range, properly made wireless mic for mobile video recording at 2.4G can be used in practically every country without a license. It exempts users from all regulatory ambiguity.

Despite the fact that wireless microphones for video with Bluetooth technology are based on the standard, there are still Bluetooth compatibility concerns. This is due to a variety of factors including profiles, drivers, and versions. This is particularly relevant to Bluetooth 4.0's low-energy technology. Other Bluetooth versions will not be compatible with a Bluetooth 4.0 connection.

Table: pros and cons of 2.4G and Bluetooth microphones

Product

Advantage

Disadvantage

2.4 GHz microphone

  • Better sound quality
  • Less latency
  • Long transmission distance supports free movement
  • Compatible in all countries
  • Free your hands
  • May occupy the charging port

Bluetooth microphone

  • Easy to pair with mobile phone
  • Support long time shooting by charging your phone
  • Usually handheld
  • Latency is noticeable and bring bad viewing experience
  • Bluetooth 4.0 is typically not compatible

When to use: it is ideal for movable recording

From the above we know that each type of wireless mic for video recording on android or iPhone is ideal for shooting that requires free movement and easy setup. For example, you can use the wireless mic for youtube videos such as shooting vlogs with your phone. 

With a microphone with either 2.4G or Bluetooth transmission, you can pair it with your phone immediately and begin the on-the-go shooting. Moreover, you can move and record the sounds you want freely within the transmission distance without the restriction of cable. Also it is a perfect wireless mic for video recording like interviews, podcast, live streaming and suchlike shooting. But pay attention that Bluetooth mic is shorter in distance and has higher latency, sometimes it may affect your audio performance.

In a nutshell, a microphone for mobile phones offers great convenience but is not good at recording high end sounds. For recording that requires professional audio like studio filmmaking, an on-camera microphone is a better choice.

    Conclusion

    A wireless mic for mobile video recording is good for your phone filming. No matter it is in 2.4G or Bluetooth technology, it provides great audio solution for your video. You can choose one according to your need and then begin the content creation.
