The high-end Bluetooth speaker market has always been occupied by international manufacturers such as JBL, Bose, and at the price of tens to hundreds of yuan, it is full of domestic low-end brands. Until Apple launched the smart speaker HomePod this year, it seems that it will lead to a transformation of Bluetooth speakers. For a long time, the 100 yuan Bluetooth speaker gave me the impression that there was no sound quality to speak of, until I experienced the VAVA Voom20 Bluetooth speaker, which changed my view.

The packaging of the VAVA VOOM20 Bluetooth speaker is very simple. The black overall packaging is the main part of the package, and the inconspicuous product rendering is very low-key.

In terms of accessories, in addition to the speaker body, a storage bag, data cable and audio cable are also included. The storage bag is very practical for outdoor travel. The audio cable of a Bluetooth speaker is not commonly used. The only purpose I can think of is to connect a computer host without a Bluetooth module.

The size of the VAVA VOOM20 Bluetooth speaker is not very large, but its weight is sufficient. The body fits perfectly, giving the impression that the workmanship is very solid,

The VAVA VOOM20 Bluetooth speaker is rectangular in shape, but the body is chamfered to a large extent, so the body is cylindrical. The pronunciation units are at the front and rear sides, and the VAVA VOOM20 uses a combination of two 1.8 "full frequency units+two groups of passive diaphragms.

The function keys of the speaker are located on the top, and the Bluetooth and power indicator light. It is worth mentioning that the VAVA VOOM20 Bluetooth speaker also supports the NFC function, which can be quickly paired with a mobile phone with NFC function by gently touching it. The keys of the VAVA VOOM20 Bluetooth speaker are no different from those of the general speakers. They are traditional physical keys, and the key range is moderate and comfortable; The power indicator is clear at a glance, so the interaction is very simple, and there is almost no learning cost.

On the bottom is the product information of the speaker and four non slip floor mats.

All the interfaces of the VAVA VOOM20 Bluetooth speaker are hidden on the side of the body, AUX audio interface, MicroUSB interface and a standard USB interface.

The two ends of the speaker are rubber planes, which also have anti slip effect, so the speaker can also be placed vertically.

It is worth mentioning that the VAVA VOOM20 Bluetooth speaker is built with British CSR8645 chip, which supports APT-X professional audio decoding technology. The effective distance within 360 degrees is more than 10 meters, which can retain the original audio elements as much as possible, so that the final compressed audio file can restore the original details as much as possible. APT-X technology requires both the player and receiver to support APT-X, and the one plus five used by the author also supports APT-X, so you can enjoy the high-quality music brought by APT-X professional audio decoding technology.

In terms of the stability of Bluetooth signal connection, after actual measurement, the signals across one wall are stable and normal, and the signals across two walls are intermittent and cannot be used normally.

Similarly, the VAVA VOOM20 Bluetooth speaker supports the call function. It is equipped with CVC6.0 noise reduction technology to ensure clearer call quality. But we seldom make calls through the Bluetooth speaker in our daily life.

The VAVA VOOM20 Bluetooth speaker has a 5200mAh large capacity battery, which can be used as a mobile power supply to charge other devices in an emergency. In terms of endurance, the official said that the endurance time of 8-hour audio broadcast was provided. After actual measurement, the endurance time of moderate volume was about 7 hours and 30 minutes, which was not much different from the official propaganda.

The VAVA VOOM20 Bluetooth speaker has a combination of two 1.8 "full frequency units+two groups of passive diaphragms. It has a built-in British CSR 8645 chip, supports APT-X professional audio decoding technology, and uses Waves MaxxAudio acoustic solution, which can be described as a luxury configuration of a hundred yuan speaker.

Because the VAVA VOOM20 Bluetooth speaker supports passive dual membrane resonance technology, it has a sufficient sense of low frequency, is flexible, and will not feel loose or weak; In the process of listening to human voice, rich low-frequency rendering makes the sound more magnetic; Intermediate frequency performance is basically enough, and there is no broken sound in the treble part. In general, the sound quality of this speaker surprised me very much.

Xiaomi launched Xiaomi AI smart speakers, officially announced to join the smart speaker war, and build Xiaomi smart speakers into artificial intelligence life assistant and intelligent device control center. Compared with VAVA VOOM20 Bluetooth speakers, they can't provide online music, voice control, artificial intelligence and other functions. They are really inferior in terms of functions, but the smart speakers at this stage are still immature and still can't provide a perfect user experience.

Although the VAVA VOOM20 Bluetooth speaker is absent from the trend of AI smart speakers, it is excellent enough in all aspects as a traditional Bluetooth speaker. With a fully integrated body, APT-X professional audio decoding technology and excellent bass performance, the comprehensive experience is far more than my understanding of a 100 yuan speaker, so this Bluetooth speaker is very recommended.
