high-yield audio equipment manufacturer Kema has recently released VDLive10, a 2.4G wireless one-to-two USB microphone, priced at 1,000 yuan, comes with a charging storage box, available in black, white and pink colors, and also an Apple Android interface. VDLive10 can be transmitted in two directions. It can be used for daily video shooting and radio, and also supports various scenarios such as online live broadcast, conference and teaching. It is a radio tool for mobile Vlogs and live broadcast experts!
There are many choices for wireless microphones on the market. Let’s start by talking about the biggest feature of this VDLive10, which is its function of two-way transmission of audio data at the transmitter and receiver ends, that is, the transmitter and receiver ends can monitor each other. A conventional microphone can only monitor the sound of the transmitter on the receiving end, and cannot monitor the sound of the connected device on the receiving end. But VDLive10 can realize such a function. The specific implementation method is to first pair the transmitter and receiver, then insert the receiver to the mobile phone or computer, and then turn the microphone switch to "D", which is two-way mode.
This way, you can monitor the sound of the transmitter microphone through the receiver, or the sound emitted by the connected device on the receiver through the transmitter. Thanks to this feature, it will be very convenient to use this wireless microphone on your mobile phone for outdoor live broadcasts. Perhaps the product name VDLive10 is named for this.
When using VDLive10 on your mobile phone for live broadcast, there is no need to plug in the headset cable to monitor the audio effect at the 3.5mm audio interface of the mobile phone. As long as you insert the headset at the 3.5mm interface of the microphone transmitting end, you can not only monitor the sound of the microphone, but also monitor the sound of the mobile phone. Users use it to broadcast the radio in the "single-soldier" live broadcast, and they will not be stumbling by the spider-web-style connection. The monitoring and radio can be done by themselves, and the inside and outside of the picture are both beautiful and neat. Of course, you can also turn the switch to "S" and return to one-way mode, which will return to the same usage mode as the normal wireless microphone.
Lower audio transmission delay
This VDLive10 uses WIFI as wireless signal to transmit audio. Although WIFI is 2.4G wireless technology like Bluetooth, compared to Bluetooth, WIFI is characterized by high bandwidth and low latency, which can bring two benefits. First, it ensures that the speed of speech is more natural during the live broadcast. In the "single-soldier combat" live broadcast work, in order to ensure normal radio reception, you usually need to take selfies while monitoring yourself.
If the wireless microphone delay is too high, it will cause such consequences. After saying a sentence, I was about to say the next sentence, and found that the voice in the monitor headphones has not been synchronized, so I would subconsciously wait for the voice in the headphones to finish speaking. As a result, the speech speed will become slower and slower and more unnatural. This situation will have a bad impact on the quality of the live broadcast.
VDLive10 Because it uses WIFI technology as a wireless signal, the sound delay is particularly small, and we have almost no obvious delay in the human ear audible recognition during our actual use.
The second advantage is that the sound and picture match a higher degree. The 2.4G Bluetooth technology will have a greater delay than the WIFI in sound transmission delay. During shooting, if a microphone with Bluetooth technology is used to receive the radio, the existence of the delay will make the sound and picture feel dislocation. Although such misalignment is not obvious in shooting scenes with small movements, if a scene with large and fast movements is taken, the phenomenon of sound and picture dissynchronization will become obvious.
If the filmed content needs to be produced after post-production, such delay can be adjusted, but if it is a live broadcast, such misalignment will affect the viewing effect to a certain extent.After consulting the information on Kema official website, we learned that the audio delay of VDLive10 is less than 20ms. Although we did not quantitatively test the specific delay time of this product, we can indeed feel that VDLive10 has a lower latency compared with wireless microphones with Bluetooth technology. We connected the Bluetooth microphone into the left channel and VDLive10 into the right channel. We recorded a piece of sound material and placed it on the non-programming for observation. We can also clearly see that the delay of the Bluetooth microphone is higher than that of VDLive10.
More stable sound collection and monitoring methods
Currently, among the small wireless microphones suitable for mobile phones, some of which only have a 3.5mm jack as the audio output interface. In this way, either insert the headset to monitor and cannot plug in the phone to receive radio, or insert the headset to monitor and cannot use the headset to monitor. VDLive10 avoids this embarrassing situation through design, and it also has a 3.5mm jack and a USB interface as an audio output interface.
The current package has two options: USB-C plug for Android and Lightning plug for Apple devices. No matter which plug is used, after plugging the plug into the device, the two interfaces "each does their own job". USB is responsible for transmitting digital audio to the device for recording, and 3.5mm is responsible for transmitting analog audio. Just plug in the headset to monitor the sound, which can not only monitor the sound of the microphone, but also monitor the sound played by the phone in two-way mode.
During live broadcast or recording video, it can monitor the device's prompt sound in real time, and monitor the microphone's sound to ensure the safety of recording, and ensure that the sounds of both the device and the microphone have the appropriate volume when mixing.
is more comprehensively compatible with the current common devices
VDLive10 Different packages have different colors and plug types. Its plug and 3.5mm audio hole can serve as the output interface of audio signals to transmit audio signals to different types of devices.
If it is used for smart devices such as tablets, mobile phones, or PCs, the plug can be directly inserted into the interface of the smart device. In this way, the audio signal can be directly transmitted to the smart device in the form of a digital signal, omitting the digital-to-analog-to-analog conversion process, so that the sound collected and recorded by the smart device has a higher quality.
If it is used for audio recorders, cameras, cameras and other equipment, the transmitter and this type of equipment can be connected together for radioing through a 3.5mm audio cable. In imaging devices, audio devices, and smart devices, it can all use its expertise to provide guarantees for sound collection and recording.
has a rechargeable storage box
Small size devices are most likely to be lost. In order to ensure that the device is not easily lost when used, Kema specially designed a charging storage box for VDLive10.
This box has a built-in magnetic suction device. After the microphone is used up, it is easier to be sucked into the corresponding groove for fixing and storage. Moreover, each groove has a charging contact, and it is actually the charging time after storage is completed. When used again, the power of each device is replenished to a certain extent, making it more secure to shoot and radio.
In addition, there is a one-click pairing button outside the storage box. Before connecting the device, you can press this button to pair. If there are particularly important and urgent situations to shoot, this button can ensure that the power is turned on quickly and the wireless pairing connection is completed, and the link will not be dropped in unsuccessful shooting scenes.
Even if the box and wireless microphone are exhausted, charging the device during rest at night, only one cable is needed to charge all wireless microphone devices, saving space and energy, so that we, who have worked hard to shoot for a day, can rest as soon as possible.
Let’s talk about the sound quality of VDLive10. Its frequency response range is 80Hz-20kHz, which is narrower than the frequency response range of professional gun microphones 20Hz-20kHz, which is mainly reflected in the response of low-frequency sound. But from another perspective, VDLive10 is not a microphone that focuses on sound quality, which is not a bad thing for users. When recording radio in live broadcasts and other scenarios, the low frequency noise during the equipment operation in the environment will be cut off, which is equivalent to the low-cut function of some gun microphones. Therefore, when using it to record vocal explanations, the low-frequency noise will be cleaner in noisy environments, so that your live broadcast has a better voice experience.

The functions mentioned above are functions that we use frequently. Let’s briefly summarize: the function of two-way monitoring allows you to stay away from your phone when taking selfies, and it can also be convenient to monitor, avoid link loss. WIFI wireless technology has lower latency, and the speech speed is natural when self-monitoring, and will not be delayed by delay. When plugging the USB plug on the receiver into the smart device, you can still monitor the sound of the device and microphone through the 3.5mm audio interface on the side to ensure safe recording. There are enough interfaces to choose first, which can be compatible with multiple devices. As long as there are cables, you will not be afraid of being blocked. Storage and charging can be done in just one box, greatly saving maintenance time and physical costs.
That’s all for today’s sharing. Finally, let’s have a small interaction. When choosing a wireless microphone, what aspect of its performance is the most popular?
