You may have heard of Mirage Sun Xiaosheng, Yangmei Breathing and other resonance speakers. These products have really made Mirage popular in recent years. The cheap price and high sound quality have made Mirage's sound recognized by consumers. The recently launched HiFi2.1 Bluetooth audio of Mirage Xiaobei has made a great contribution to the price performance ratio. Compared with other Bluetooth audio systems, such as Beats poll series, boss series, Sony series and other HiFi level Bluetooth audio systems, Mirage Xiaobei is very friendly. Now let's have a look at Fantasy Beckham.

1、 Unpacking

[Note] Since there is a lot of residual glue on the box, the shooting effect is poor, so the picture of the box is not uploaded.

The packaging box is a flip type packaging, and the mainframe of Mirage Xiaobei is fixed by two pieces of customized cardboard, but the cardboard has been deformed when received. Hopes the manufacturer will work harder on packaging. Package includes: AUX audio cable, power adapter, host, warranty card instructions.

Mirage Xiaobei is a HiFi level speaker that supports both AUX connection and Bluetooth connection. It is also equipped with five sound generating units, which can form a 360 ° surround effect, making the sound field more open and the hearing effect better.

The white appearance of Miraculous Xiaobei looks like a shell. The skin like surface feels good, but white is easy to leave fingerprints and dust. The sunken top is the woofer, and there is a circle of led lights around as decoration and indicator lights. Top The keys are touch sensitive, and their functions are slightly different in AUX and Bluetooth modes.

There are four rubber pads at the bottom and two passive units distributed in the form of holes, which are similar to Sun Xiaosheng. "Super energy crystal" resonance sound generation technology, such as sheep eyebrow exhalation.

The front and side are surrounded by metal mesh, and there are two 1.5-inch high-frequency sound generating units on both sides of the front.

From right to left on the back are the power indicator, mode conversion key, charging interface, AUX interface and power key. When the power is connected, the LED light will show blue light. However, the size of the AUX port is very close to that of the charging interface, which is easy to be confused if it is plugged in blindly.

2、 Product use

（1） Sound unit configuration

The sound generating unit configuration of Mirage Xiaobei 2.1 HiFi audio includes two 1.5-inch full frequency speakers, one 2.5-inch low-frequency speaker and two passive units.

The following is Baidu Encyclopedia's definition of passive radiator:

//baike.baidu.com/link?url=Hyu4 -SZU-FW1dmSIpx_L56WC8GYfvh-3veBRLz8hGmprr02eaC9H4ma-uKjZxpmTaUjliOCrOYVTjxpC2ZYk5_

Audio using "passive radiator" usually includes an active speaker unit and a passive unit (passive radiator). The passive unit is usually similar to the active speaker unit in appearance, but without voice coil and driving magnet. It has only one paper basin and is not connected to any voice coil or circuit. Passive radiator is usually used to adjust the bass, so that the designer can adjust the overall voice color of the speaker. The passive radiator makes a passive sound driven by the air in the loudspeaker box by the active unit in the loudspeaker box.

Usually, the passive radiator is used to replace the inverter tube to adjust the sound quality of the smaller box and make it have better bass performance. Especially in some cases, because the box is too small to install the inverter tube, the passive radiator is a good alternative. It is also usually used to eliminate the disturbance of the box airflow and reduce the compression of the loudspeaker unit stroke caused by the high-speed movement of the airflow in the inverter tube.

The audio processing chip of Mirage Xiaobei is the NPCA110P audio enhancement engine and codec chip. There is no doubt about the analytical power.

（2） Connection and use

As a speaker featuring Bluetooth connection, Xiaobei has its own Bluetooth 4.0 protocol and is downward compatible with Bluetooth 2. The Samsung Galaxy S4, Macbook PRO, iPhone6s, and Surface PRO connections were all tested without problems.

Xiaobei needs to press the power key for a long time when he starts up, and then he will hear a ding dong (the voice of Ali Wangwang), and then he will be prompted by voice about the current mode. The default mode is the last one used.

The following describes the three capacitor buttons on the front of Xiaobei. In AUX and Bluetooth modes, the functions are different, and the functions of long press and short press are also different, so there is a greater possibility of misoperation.

Xiaobei's five sound units form a strong surround sound effect, which has a good impact (the sound quality will be described below). Secondly, the volume is really high, which can be used as the high pitch horn of square dance. However, even if the voice is turned to the maximum, there is no obvious distortion. The bass sound generator will cause resonance at the low pitch.

The actual audio used is as follows:

Use iPhone 6s Netease Cloud Music to play Formation Beyonce. The recording is as follows

Play Hometown Glory Adele recording with iPhone 6s as follows

straight There is no such obvious current sound when listening to Xiaobei, but there is such obvious current sound when listening, which does not rule out the problem of the radio equipment. When Xiaobei's volume reaches a certain level, it is enough to completely cover up the current sound. However, if the volume is too high, it will cause harm to the human ear, so there are drawbacks and slots. In AUX mode, the current sound will be significantly reduced. However, the AUX connection mode is relatively limited, so users still have to make a choice in terms of sound quality and convenience.

Sound quality: The high pitch part of Mirage Xiaobei 2.1 HiFi audio is not particularly brilliant. The penetration is not enough. It feels stuffy inside. The baritone part is in order. On the contrary, its low-frequency sound has passed my test song: if I was a boy beyonce, I can clearly feel its excellent low-frequency sound, without the crater shape on the top of the waste. At low frequencies, the super energy crystal at the bottom vibrates obviously, and does not deserve the title of Mirage brand subwoofer before.

（3） Endurance

Xiaobei has two 2200mAh lithium batteries. The official said that it can last 8 hours at 50% volume and 3.5 hours at maximum volume. However, in the actual experience of Xiaobei, the volume will be much larger than that directly played on the device, so it is almost impossible to use more than 50% of the volume. The endurance is satisfactory.

The measured results are still good. After full charge, the Bluetooth mode is maintained for 2 days. After about 7 hours of actual use, the system is powered off automatically after power failure. This endurance performance is more than enough for heavy users who listen to music every day.

Xiaobei is a high cost performance HiFi2.1 Bluetooth speaker. Compared with the Bluetooth speakers with the same price on the market, he is an outstanding speaker. If you don't want to buy a spicy chicken subwoofer and you are temporarily short of funds to buy high-end audio, then Xiaobei can become one of your first choices.

3、 Summary

Advantages: Fantasy Xiaobei has the mainstream Bluetooth audio connection mode, HiFi2.1 high audio quality experience, high face value, etc.

Disadvantages: misoperation on the keys, 3.5mm audio cable is too short, the audio cannot control its own volume and its own volume is too high, and the packaging also hopes to improve the protective pad.

Suggestion: At present, intelligent hardware leads the trend. In this regard, Fantasy Xiaobei can also add more connection methods, such as WiFi, USB interface, etc., and even add app operations. I hope the manufacturer can improve the user experience more.
