With the improvement of the national living standard, in addition to meeting the daily pursuit of material consumption, music is indispensable to accompany people when they are at home for rest, ordinary gatherings, outdoor travel, etc. Mobile phones may be the most popular devices for playing music at home. The volume and sound effect of mobile phones are limited, which may be less practical outdoors, Outdoor play may require loud speakers, which is not conducive to carrying. At this time, as a small and portable speaker, it does not take up space whether it is carried at home or out, and the sound quality is also guaranteed to a certain extent.

When it comes to the sound quality of Bluetooth speakers, it may be that people who have used them know how to perform. The author wants everyone to experience the sound quality of this VAVA Voom20 portable Bluetooth speaker?

VAVA Voom20 is an audio-visual product under the VAVA brand in the United States. Its oval appearance design is covered by a selected 6000 aviation aluminum alloy iron mesh. The key layout and bottom are made of rubber material with strong anti-skid friction, which is generally resistant to dirt. The body weight is 694g, and the length is about 19.25x7.15x6.05cm, The feeling of holding in the hand is weighty. The simple and grand appearance design has added a lot of points to his appearance. What the author is curious about is how to remove this product. There is not a screw for fastening outside, which integrates metal mesh and rubber materials. This sense of technology and the solidity of materials are very American style.

The size of the buttons on the upper function panel is evenly distributed. To be precise, the buttons are also integrated with the body. There are not too many complicated button designs. On the far left are the power indicator, the power on/off button, logo (designed for symmetrical and balanced buttons), Bluetooth connection display (always on after successful connection), support for NFC functions, pause play and answer power Voice and volume up and down keys. From the point of view of buttons, there are two features: support for one button call and NFC function, which makes connection more convenient.

The sound effect of the VAVA VOOM20 Bluetooth speaker is so powerful, and the appearance design is so simple. Of course, the hidden design and multi-function expression of various charging interfaces and audio interfaces are also impressive. At the back of the machine body, the AUX audio interface, Micor interface and USB interface are hidden with a rubber cover. The design of the exterior keys and interface of the VAVA VOOM20 Bluetooth speaker is more user-friendly. Charging, audio interface and keys do not affect each other. The gap between the interfaces is reasonable, and will not cause confusion of the lines. The reservation of the interface is very reasonable. The author's notebook does not have a Bluetooth device. If you want to connect the speaker, you can only rely on the audio cable.

But the rubber cover on the back feels a little incomplete. From the front, the design is beautiful. The cover on the back seems to be missing a small piece. This should be like learning from Apple mobile phones. By canceling the headphone interface, the VAVA VOOM20 Bluetooth speaker can be three in one, which is beautiful and simple.

The VAVA Voom20 metal hollow design has good contact with the rubber material on both sides, with curves, avoiding the damage of edges and corners to the fuselage during collision.

Every time, you will get a family photo, USB data cable, 3.5MM audio cable, portable bag, and host computer. The accessories of each product can be said to be simple, but the VAVA Voom20 can be said to basically include all functions. If you don't reduce the accessories, you should give the product a thumbs up.

In fact, what I like most is the portable bag. When I first saw the VAVA Voom20 speaker, I looked from the outside. I was thinking that a portable bag would be the best. The portable bag you wear is more different from the ordinary storage bag, so the portable belt with better sealing can protect the speaker from more dust, thus affecting the sound quality. It also has the same waterproof effect. Timely outdoor tourism can also play a very good role in protection.

To talk about the endurance of VAVA Voom20, it is worth mentioning that it has a 5200mAh battery capacity, and can also reverse charge the mobile phone to alleviate temporary needs. It serves as a mobile power function, and can basically see the humanized design in the current smart devices. Its official claim is that it can provide 8 hours of audio playback, and the author can use it every morning and evening for five days. This is enough for the use of light trucks in daily places. Even if it's square dancing, it's OK for a day.

It also has IPX5 outdoor waterproof grade, which should be regarded as the gospel of outdoor users, and can meet the daily needs of outdoor users.

The VAVA Voom20 Bluetooth speaker uses the resonance bass technology that is not mentioned, but the bass effect is absolutely good. From the front, you can see two independent 1.8 inch full pitch speakers on both sides vaguely through the metal mesh, and the middle is a combination of passive dual membrane resonance technology, both of which are designed to optimize the bass effect and make the playing vaguely more elastic, low and heavy. In addition to providing high-quality speakers, of course, it also needs a powerful inner core, which is built with British CSR 8645 chip, supports APT-X professional audio decoding technology, and uses imported ceramic antenna to stabilize the signal channel and prevent interference. Let's listen and experience together when the hardware and body parts are up to standard.

There are two ways to connect mobile phones. One is to use Bluetooth to connect directly, and the other is to use NFC function to connect. 6s is not open at present, and the existing Android smart phone supports NFC to connect.

In terms of sound quality, high-quality sound effect tuning, using Waves MaxxAudio acoustic solution, has experienced more than 30 times of sound effect debugging by senior tuners. This time, the emphasis is on the details of the bass. During the audition, the bass is really elastic and thick, but it does not lose the sense of delicacy. The feeling is very heavy, but it is very vivid, and there is no broken sound or distortion. The sound in the outdoor is no less than the effect of big speakers pulling along the street. The author was deeply attracted after listening to it once, and planned to take it with him later.

There are 15 levels of volume adjustment (coarse number). When the volume is adjusted to the maximum, the whole floor is shaking. I feel that the anti slip mat under the VAVA Voom20 Bluetooth speaker is very effective, not that it shakes back and forth. When the volume is turned to the minimum, it is about the same as the minimum sound of the mobile phone. It is also equipped with the function of one button call. With CVC6.0 noise reduction technology, the call quality is much better than that of mobile phones.

Use 6s to test the VAVA Voom20 Bluetooth speaker. The official said that the effective distance within 360 degrees is more than 10 meters. It is OK indoors, but the blocking signal of a car outside has an impact.  

Summary:

The VAVA Voom20 Bluetooth speaker has an all metal hollow design, and its body has a simple and fashionable appearance in European and American style. The button operation on the front and the interface function on the back are very comprehensive. It is designed for home and outdoor Bluetooth speakers and supports IPX5 waterproof. I like the sound quality and bass effect most when I use it. It is thick but not heavy. It can be connected to the mobile phone in two ways. It also supports reverse charging, even if it can replenish the power of the mobile phone. I don't know where such a perfect design is opening a gap. The author thinks it would be better if the radio function was added, and the VAVA VOOM20 Bluetooth speaker would be loved by more users in the position of a mobile phone or SD card in the appearance design. In general, the sound quality of the VAVA Voom20 Bluetooth speakers in the low, medium and high frequency bands is very satisfactory. Generally speaking, the price performance ratio is quite high at the same price. The VAVA Voom20 Bluetooth speaker can fully awaken your lifestyle with high quality.
