It can be said that it is the age when Bluetooth speakers were popular. There are several speakers in every family. Even my old parents who were nearly 80 years old were one and the people who listened to music with small speakers in the street were everywhere. But if you are walking in the rain or taking a shower, you dare to stay with the speaker Are you handsome? If you dare not, I Today, I would like to introduce a small speaker that is not afraid of being drenched - Kuwo spray anti drenching Bluetooth speaker. Everyone who mentions Kuwo and likes listening to music should know it! This speaker is a new product for Kuwo Music to expand into hardware. Now please join me for a taste!

Appearance and configuration

Simple white carton packaging, clean and neat. There is a small Kuwo music logo printed in the middle, which is Very conspicuous Love to play computer games The trial tag stole the camera.

This speaker is produced by Tianjin Kuwo Technology and produced in Dongguan (it seems that Dongguan is not only able to provide x services, but also has manufacturing strength).  

All sides of the speakers in the box are covered with foam, so there will be no problem if they fall from a height of one or two meters.

The accessories include charging line, lanyard, product certificate and instructions.

The cylindrical fuselage, outside of Tuhaojin, the edges and corners are all chamfered and polished, which adds a touch of aura. With the black mesh top, it looks a little luxurious and solemn, a little like a small steel gun.

Sunflower shaped hollows on the top Black plastic horn mask, center gold Of The logo of Kuwo stands out against the black background.

loudspeaker box There are three keys , the switch key is centered, and the left and right volume increase and decrease buttons are respectively used. The key switch also has functions such as play/pause/Bluetooth, TF card, USB sound card mode switching, etc. The buttons are designed to sink slightly, so they are not easy to be touched by mistake.

At the bottom of the other side of the corresponding button is a lanyard hole. The design is not centered. It's not very beautiful to imagine lifting it diagonally, which makes me a little strange.

  The central part is A disc with rubber rings around it printed with Kuwo's logo "KUWO", The elastic displacement will be obviously felt when touching with fingers. This is Low frequency radiator, We need to popularize science, The low-frequency radiator box structure is adopted. The airflow is produced inside the box to promote the low-frequency effect of the radiator. The airflow sound can not be heard outside the box, so the low-frequency sound produced by the low-frequency radiator box will not produce low-frequency distortion at all. The low-frequency effect is better than Most subwoofers use a more realistic way to improve the low-frequency effect by using a sound guide tube that is easy to cause airflow sound.

There is a rubber circle Base with The three ridges are in a slope shape, which not only ensures the support function, but also leaves a gap for the sound at the bottom to be emitted, so as not to affect the bass effect of playing, and not to cut the hand when holding it in the hand. although soft Rubber can play a cushioning role, but its disadvantage of easily adhering to dust cannot be eliminated. It is good to say that it can not be seen at the bottom when used on the desktop, but it may be slightly uncomfortable when held in the hand. In addition, the gap between the three keys and the key hole is also a little large, which is not fine enough.

Inside the bottom mat are two crescent shaped rings, one of which is made of rubber with TF and USB logo printed on it.

This rubber block can be buckled from both sides, and TF card socket and USB socket are hidden under it. These two sockets are the key waterproof points of the whole speaker. As can be seen from the figure below, two main measures have been taken: one is the rubber ring protruding from the rubber block Grooves around the spigot, It forms a seal and plays a waterproof role; Second, there is also a bulge at both ends of the rubber block, which is inserted into the corresponding groove at the bottom to increase the adhesion, so that it will not be lifted easily and increase the reliability of waterproof sealing.

Take a closer look from another angle.

The following video can give you a comprehensive and detailed understanding of its appearance.

Use and Experience

Operation: Fully charge through the mini USB port, press and hold the power key for power on, and the power on voice will appear“ Good sound quality Use Kuwo ”And "Bluetooth Profile" Tips , the default boot status is Bluetooth mode. The white indicator light on the top near the switch key flashes quickly, waiting for the Bluetooth connection. After the connection is successful, it will flash slowly (about once every ten seconds). If Bluetooth has matched other players, you can hear them in a second or two“ Bluetooth Connected ”Voice prompt for. Its Bluetooth search speed is the fastest among similar small speakers I have ever used,

At this time, you can open your mobile phone and other playback devices to play local music, or open apps such as Likouwo Music and QQ Music to listen to online music resources.

TF card playing mode: Double click the ON key to switch between Bluetooth and TF card playing modes. At this time, there are three rapid flashes of red light and voice prompts (such as "TF card mode" and "USB sound card mode". If no TF card is loaded, it still prompts "Please insert the card without TF card"). TF card can play downloaded lossless music to improve sound quality.

USB playback mode: After connecting the computer and other playback devices with a data cable, it can be used as its playback device. It is much smaller than the usual computer speakers. However, after the data cable is connected, it can only be placed upright, and the round side cannot be stabilized. After checking the official website, there is a special silicone base for sale, which should be the standard configuration!

One problem with function conversion is that the key switch is pressed very hard, and there is no problem when you click it. When you double-click the key switch quickly, you feel very unaccustomed. You have tried N times before you get used to it, but the success rate of function conversion is still only 70% or 80%. In addition, there is no pause function in USB playback mode, and it can only be operated on the computer.

If there is no play or operation for about five minutes, it will automatically shut down.

Audition ：

Volume: The volume is not big and the voice is not small. The volume is relatively high when listening indoors, When I turned up the volume to the maximum, my daughter-in-law jumped. I didn't expect such a small thing to have such a loud voice. But the experience feeling in the noisy outdoor environment is just so so. It's OK to listen to three or five people around. Compared with the volume of my other two larger Bluetooth speakers, the sound is very powerful, a bit like a small steel cannon.

In addition, it is worth mentioning that there is no sound breaking phenomenon when playing at the maximum volume, while my other two Bluetooth speakers have different degrees of sound breaking distortion at the maximum volume, which is surprising.

Sound quality: I still want to use my favorite Cai Qin《 ferry 》Let's experience the mid-low sound effect of S7.

I prefer to use the bagpipe "Black Rose" to feel the treble.

After listening, I feel that the sound is bright and thick, with little distortion, The voice is quite clear, The bass is relatively thick and strong.

On the other hand, you can see the intense shaking of the low-frequency radiator at the bottom during the playback, which seems to be the same as the subwoofer. It feels very cool. No wonder you call it Kuwo Spray Speaker!

Watering: Since it's an anti drenching speaker, you can't stop trying! At the beginning, I carefully tried to catch the water with my hands, and I felt nothing after several attempts. It's not satisfying to drench. Let's try another powerful one and water it directly under the water-cooling head. It's still no problem, especially when splashing water on the loudspeaker!

After taking a bath, she became more lovely and still sang freely 。

After the actual water drenching test, we can use it in outdoor activities such as cycling and outings with complete confidence. We don't need to worry about the impact of rainy weather any more A travel stereo is very good. In addition, the shower room, swimming pool and other splashing places are no longer forbidden areas, and music can also be enjoyed.

Of course, it's better not to soak in the water. After all, the rubber seal alone cannot ensure the safety of underwater use for a long time. If you accidentally fall into the water, you will not have problems immediately.

Carry: Hold it in your hand, It's very pressing. It's the smallest of my three Bluetooth speakers, but it's very heavy, reaching 217g.

It looks good on the dashboard of your car.

Speaker diameter Slightly It's a little bigger, the corners are not too smooth, and the grip is average.

It should be better to put on the lanyard and carry it by hand or hang it on the bag carry Mode. After putting on the lifting rope, the expected oblique hanging appearance came!

Endurance : Based on the 800mAh battery, it is not a problem to listen to music continuously for more than 7 hours in the actual test.
