In recent years, people have been consuming more and more audio products, and their requirements for audio quality have become higher and higher. The portability and good audio quality of Bluetooth speakers have attracted many users' attention. Both BOSE Soundlink Mini and SONYh.ear go are very popular among digital enthusiasts in the market. Most of them are deeply fascinated by their refined appearance and sound quality. I have written a similar article before, and interested friends can search my previous articles, But today's VAVA Voom20 is the latest product under the VAVA brand from the United States. It has the same simple and elegant design as the above brands, and won the Red Dot Design Award. In addition, its rich and three-dimensional sound also makes its sound quality excellent. Its main design is portable and IPX5 waterproof, which makes its application scenarios more rich, The most important thing is that the product price should be much lower.

Of course, as a 699 yuan speaker, quality control and sound quality are equally important. The VAVA VOOM20 all black package looks very textured. The product rendering on the surface of the box shows that the speaker is multi button layout, supports NFC one button connection, and is more convenient to use.

In addition to the charging data cable and audio cable, the free accessories also include a storage bag, which is more convenient to carry out.

Although the VAVA VOOM20 Bluetooth speaker is mainly portable, due to the use of the dual membrane resonance technology combination of 2.7 "thick front diaphragm and 4.3" thick diaphragm, the product also has a little weight under the condition of heavier bass. All the screws of the integrated alloy body are embedded design, so no screw can be seen on the whole speaker appearance, and the workmanship is very solid.

The black design of the VAVA voom20 Bluetooth portable speaker has a strong overall sense, and it is also very artistic. It has a built-in mic hands-free call, which also makes it convenient for users to avoid the tedious task of disconnecting Bluetooth in the process of use. In addition, it is also very practical in scenarios such as teleconferencing. This function is also my favorite.

Because this speaker is IPX5 waterproof, the interface is also sealed with a rubber cover. After opening, you can see the internal interfaces: USB interface, Micro interface and AUX audio interface. Many people feel that the AUX interface is useless, but when we encounter a device without Bluetooth, we can use a 3.5mm audio cable. The built-in 5200mAh battery provides up to 10 hours of life. The device can be charged in an emergency through the USB interface, which also plays a greater role in the outdoor.

The four anti slip foot pads at the bottom make the product more stable when playing, and also ensure high-quality audio output.

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.

In terms of Bluetooth, the imported CRS4.0 chip with four core computing capability is adopted, which supports simultaneous access of two devices. The input source can be controlled through the mobile terminal, which also facilitates our use. Through the metal mesh, it can be seen that two independent 1.8 inch dynamic full frequency tweeter units and a dual mode resonant bass unit at the front and rear are built in front of it, making the bass dive deeper and more elastic.

Built in imported high-performance CSR8645 chip, combined with APT-X professional audio decoding technology, the effective distance within 360 degrees can reach more than 10 meters, fully adapting to the hardware characteristics of small speakers, making distortion suppression smoother during large dynamic, giving you authentic music performance.

In fact, I was surprised to support NFC. Although NFC is mainly used for payment and personal information interaction, and the transmission distance is also far less than Bluetooth, the setting and use process is much simpler than the latter, which makes the device connection and use more convenient and easy. It only needs to close the NFC device to the sensing area on the top of the speaker for data communication.

Both Bluetooth and NFC are very stable in use. The transmission distance of Bluetooth can still communicate well in different rooms indoors, and can reach an effective transmission distance of 10 meters outdoors. The convenience of Bluetooth speakers is greatly reflected.

Similarly, the hands-free phone function supported by VAVA VOOM20 also has a great demand for many users. The specially equipped CVC6.0mic noise reduction technology also makes the call sound clearer, which is suitable for both individuals and team meetings.

If the mobile device also supports APT-X, it will get excellent sound effects: life will be fuller and mellower, the sound field will be wider, the bass part will dive deeper and be more flexible, and the high-frequency part will have rich details, which is more than enough to deal with ordinary music and retain the original flavor of music.

In Li Yugang's Just Met You, VAVA VOOM20 showed the drum beat of each section in a very good way, and the guitar melody was also very good at the beginning. Especially when the chorus teacher Li's cross dressing of girls' delay and high and low links pushed the whole song to the climax, the speaker also perfectly displayed the voice line of "women". The "boys and girls" were very pure and quiet, I didn't feel the inflexibility brought by the tone sandhi falsetto. The timbre is clean, not harsh, and has a sense of space. It is the most successful part of this song and my favorite.

When auditioning a popular online song "We Are Different", I was very satisfied with the expressiveness of the whole song, especially the first half of the piano and the sound of the great vicissitudes of life. The voice show is also very full of porcelain, and the medium and low frequencies can be well presented, making people sound comfortable.

During several days of audition, VAVA VOOM20 really gave me a big surprise. It has a very good presentation for most songs, especially for popular songs. Thanks to the introduction of passive bass units, the middle and low frequencies have an excellent atmosphere, and the middle and high frequencies have very clear and pure voice lines, which do not drown out details in the high tones, As a main outdoor Bluetooth speaker, it has good quality.

I am satisfied with several aspects:

1. Full embedded mode integrated aviation aluminum design, no screw hole can be seen

2. It supports one button hands-free call and is equipped with CVC6.0 noise reduction technology to make the call clearer

35200mHA large power, durable, and reverse charging

4. Support NFC, easy connection with touch

5. IPX5 outdoor waterproof, more free for outdoor use

Although there are many kinds of Bluetooth speakers, the VAVA VOOM20 has good advantages both in appearance and sound quality, and its price is not as exaggerated as that of other speakers that are often thousands or even thousands of pieces. Its delicate body construction and high outdoor waterproof level will make you feel extremely full when you carry it to any scene. The built-in large capacity lithium battery also supports reverse charging, which also makes this Bluetooth speaker with the positioning of "100 yuan" very cost-effective. Therefore, whether you are a fashion expert pursuing petty bourgeoisie or an outdoor enthusiast, I think the VAVA VOOM20 is worth considering!
