BY-XM6-S Series Mobile Phone Wireless Microphone Review: Portable and Compact, Stable Pickup

In the creation of live and short videos, mobile phone shooting is an unavoidable topic, which is different from traditional film and television production. The production of short video, live broadcast and other content is more efficient and convenient, while the production threshold needs to be lower, mobile phones have naturally become the main tool for such creation, at the same time, many mobile phone accessories have emerged as the times require, BOYA has launched XM6-S series of mobile phone wireless microphones, which will be tested. See if this microphone meets the pickup requirements for mobile phone shooting.

Appearance design:
BOYA has four models of XM6-S series wireless microphones. The models of S3 and S4 are the one-driving-one-version and one-driving-two-version of the lightning interface respectively, and the models of S5 and S6 are the one-draving-one-version and one-draving-two-version of the Type-c interface respectively. Because different manufacturers of Android system have different optimization for microphones, So in this test, we chose the one-drag-two version of the lightning interface to restore the performance of the microphone itself to the greatest extent.

Four Models:
Equipped with lightning interface product design, it can be applied to iPhone and iPad products.


It is equipped with a common Type-C interface on the market, which can be applied to a variety of Android mobile phones and devices equipped with Type-C interface.


Received is the XM6-S4 and its charging box set, the overall packaging is very simple, product functions and features are graphically processed, so that people can see at a glance. Microphone and charging box can be purchased separately, which gives users more freedom to choose whether they need to store the charging box or not.


When you open the package, there are all the products and accessories inside, including two microphone transmitters and one receiver, two lapel microphones, three Type-C data cables, a cloth storage bag and a charging box, which can be used in hand, so the configuration is very complete.


The appearance of the cloth storage bag is quite exquisite. The front side is engraved with the brand Logo of Boya. The light blue color matching is more obvious on the black base cloth, which can be clearly distinguished among many products. There are two mesh bags inside the storage bag. ? It is suitable for holding the lavalier microphone or wire, but there is no clear slot between the receiving end and the transmitting end, so it is easy to scratch, so it is recommended to buy a suit with a charging box.

The shape of the charging box is relatively square, with arc-shaped treatment around it, which makes the cross-section more rounded and not abrupt. At the same time, the surface treatment is more delicate. With the light gray brand logo, the overall texture has been sublimated.


The four rubber foot pads at the bottom can achieve anti-skid and anti-collision functions.

After opening the charging box, you can see that the internal space is very compact. In addition to the three slots, there is a horizontal sponge on the top of the box, which can make the contact of the transmitting end more closely connected with the contact of the charging box.

The side of the charging box has a Type-C charging port and a charging indicator.

After introducing the storage accessories, let's take a look at the main body of the wireless microphone. The transmitting end of this microphone is larger. At the same time, it shows that the mirror treatment is also used. It will not affect the appearance of the picture in the wearing of the mirror, but the color matching is relatively single. We hope that the later color matching can be upgraded to introduce more colors to adapt to more scenes.

The facade of the transmitting end is cuboid, and there is a TX logo on the front to indicate its identity of the transmitting end, and this logo is located inside the mirror, which will not gradually fade with the frequency of use, so it can still get a better evaluation in terms of aesthetics.

There are three keys on the side of the body of the transmitter, namely the minus key, the plus key, and the switch/mute key. All operations of the microphone can be realized by pressing the three keys for a short time and a long time. At the same time, the cover on the front and back of the body slightly protrudes from the side. It can better protect the keys from collision or accidental touch, and the details are still in place.


The top of the transmitting end is a microphone and a 3.5mm audio input interface, and the microphone also reserves a mounting hole for a windproof sweater, but it is not locked by rotation, so it still needs to be prevented from falling off in use.

On the other side of the fuselage is the Type-C interface.


The receiving end is relatively simple, it does not have a built-in battery, so the body is very compact, in addition to the necessary interface and keys, the overall body is relatively clean, the internal layout is also reasonable.


There are only two buttons on the receiver. One is the M/S switch button, which can switch between mono (MONO) and stereo (stereo). For the one-drag-two device, the setting of independent channel can expand the application scene and increase the space for later stage. The other button is the pairing button. ? Used to pair with the transmitter.

There is a built-in PIFA antenna on the side of the receiving end. There is a little trick in using it. Make this side as high as possible. This way of placement can improve the signal strength.


The receiving end monitors the interface

The connection between the receiving end and the mobile phone is also bulged to reinforce the connection of the interface, and at the same time, a certain amount of buffer is made to prevent the interface from breaking due to external impact during connection.

When connected to the iPhone 11, the width is slightly longer than the phone

> The size of the transmitting end is 31.37 mm
> Width 16.68 mm
> The width of the receiving end is 75.20mm


Through several sets of measurement data, we can see that the size of this wireless microphone is very compact, and it also meets the requirements of mobile phone shooting for portability, so what kind of performance will it have in actual use?

001 Sound quality test
From the parameter list, we can see that the pickup performance of this microphone is moderate. Although the frequency response range of 35Hz-18kHz can not cover the range of 20Hz-20kHz of human ears, it is enough for daily use. Audio manufacturers often do not stack parameters in terms of sound quality, because even if the microphone sound quality is good, when recording through the mobile phone, it will still be limited by the audio codec performance of the mobile phone.

This microphone has a certain noise reduction function, and will not lose too much sound quality to achieve this goal, the restoration of the human voice is still relatively real, but a part of the frequency response range is cut, it will lead to some of the sound will have a significant sense of weakening; but for the microphone used in mobile phone shooting Such sound quality is enough to be used in short video platforms or live broadcasts.

002 Stability test
The stability of the wireless microphone is the most important, even more than the sound quality. The sound quality can only determine whether the recording is good or not, and it can determine whether the recording is good or not. We will test the stability from two aspects. First of all, in terms of distance, we can test the transmission distance of this microphone by fixing the receiving end and walking forward with the transmitting end.


In the distance test, we put the microphone in front of our chest, which means that there is an obstacle between the receiving end and the transmitting end. Under this condition, we test the farthest distance that the microphone can transmit.

Through the test, it can be seen that within a distance of 30 meters, stable transmission can be carried out with or without obstacles. Beyond this distance, it can reach about 50 meters without obstacles, but this has greatly exceeded the available focal range of mobile phone shooting, so stable transmission within 30 meters is enough.

After testing the distance, we recorded the microphone for ten minutes without interruption. By enlarging the waveform, we can see that the waveform has no frequency interruption, so the stability of this microphone is still excellent.

003 Charge/Endurance Test
With the charging storage box, in fact, the battery life is not a topic we need to worry about. It can be charged after being put into the storage box. The charging voltage of the charging box is 5V, the current is 1A, and the charging power of 5 W can be achieved.


In our daily use, the transmitting end lasts more than 5 hours, and the receiving end relies on the mobile phone for power supply, so there is no trouble of battery life; however, the mobile phone is often shot to be out of power. ? The microphone still has two bars of electricity. At this time, it is hoped that the receiving end will have an additional charging interface, which can provide additional power guarantee while achieving sound pickup.

Use experience
As a mobile phone wireless microphone, it is more used with mobile phone shooting. We take it to the shooting scene of the online class to experience the performance and sound quality of this microphone.

As a popular teaching method in the context of the epidemic, the teaching content that keeps pace with the times has become particularly important. At the same time, the recording of online courses is generally completed by teachers independently, so they will choose lighter mobile phones on the equipment, which will reduce the threshold of shooting and improve efficiency.

But radio is a big problem, most of the recording scenes of online courses are not professionally processed acoustically, so the recorded sound is prone to serious reverberation. Especially for this kind of online dance class, in addition to the reverberation caused by the empty room, the distance in the demonstration will also make the sound loud and small, which will greatly affect the viewing experience.

At this time, we install Boya XM6-S4 on the mobile phone for use. Its interface is in line with Apple's MFI certification, so it will not be unable to identify in use. It is driver-free, does not need to download any APP, and the native camera can also be used, which is very convenient.

After the video recording is finished, playback monitoring can be performed through the receiving end without repeatedly pulling out the receiving end.

This microphone supports 6 levels of gain adjustment. When a male teacher with a loud voice is in class, the gain can be adjusted lower, while when a female teacher with a small voice is in class, the gain can be adjusted higher. In the editing of later courses, the unity of volume can be guaranteed to the greatest extent, so as to enhance the students' perception. At the same time, the transmitter supports 3.5mm audio input, can be connected to the collar clip microphone, in the case of doing the action while shouting the password, the pickup effect will be more obvious improvement.

In addition to the recording of online classes, this microphone can be used in all aspects of mobile phone pickup, such as online meetings, live broadcasting and other scenes. It can achieve pure voice recording, so that the background noise of the surrounding environment and daily noise are weaker.


This microphone of BOYA has really brought us a pleasant surprise. From the quality of the product and the use experience, we can feel the degree of care of the manufacturer; in actual use. Such a multi-purpose mobile phone wireless microphone greatly improves the shooting efficiency and video quality.
