● For men, I think most people would have wanted to own their own home theater, but they may have suspended or stranded their plans due to various problems. In addition, I think a lot of people have also met this situation. Whether they buy a house or build a house by themselves, they always forget to reserve the wiring of the stereo when decorating. One day when they are going to buy a home theater, they find that rewiring is a very troublesome thing, If all kinds of wires are exposed outside, it will be like a spider web. So many people give up, but some people are unwilling to continue to let TV sound poison their ears and want to pursue a higher quality audio-visual life, so they will turn their eyes to another option: integrated sound system. Today I want to introduce this model from Shenzhen Qiteng Audio visual Company Kaifly Qiteng K1 Hi Fi TV Audio is just such a product, which integrates local video broadcast and HIFI audio is integrated into one, which can let the ear accept a clear and flexible baptism while enjoying the shocking and lifelike picture. Of course, its real strength still needs to be evaluated with me.



▼ Let's start from Kaifly's outer package looks at its size. I'm afraid you have no reference and it's difficult to compare. So my family Xuanbao has shown friendship. The little model is 5 and a half years old and 118cm tall. This shows that Kaisfly has a big body. With a weight of more than 30 kg and such a big head, it is hard to carry him alone.

▼ Kaifly is dark, giving the first impression that it is "big", and its overall size is 1150mm * 340mm * 120mm, my TV cabinet upstairs is just right, which seems very aggressive.

▼ Kaifly's front face adopts a cloth mesh cover, which can prevent dust without affecting the change of voice color. In terms of technology, the traditional method of sticking PVC on wooden boxes is abandoned. The whole box is made of 12mm HDF high-density boards, which are matched with black matt metallic paint to make the sound style more noble and elegant.

▼ All corners of Kaifly are neat and round, the paint is even, the gloss is very good, and every detail shows the quality of the factory.

▼ There is a special sticker in the middle of the box "KAISFLY" product logo.

▼ Let's turn around and have a look Behind Kaifly, the machine is equipped with a physical power switch and a fuse socket. In terms of power supply 220V/50Hz 200W transmission Enter. In terms of interface, Kaifly designed AUX audio input interface * 1, optical fiber interface * 1, HDMI HD output interface * 1, wired network interface * 1, and finally two USB2.0 interfaces. Generally speaking, compared with In terms of Kaifly's market positioning, the interface is enough, but I still hope Kaifly can be more abundant in the interface, and USB can adopt a 3.0 specification as far as possible.

▼ In Six rubber anti slip pads are evenly distributed at the bottom of Kaifly. Because two woofers are designed at the bottom, the anti slip pad is particularly important. First, it slightly raises the gap between the machine and the table top, and also ensures the stability during bass vibration.

▼ The two 5-inch customized composite long stroke cone basin subwoofers at the bottom have a good effect on the actual experience. We know the bass The larger the horn diameter is, the lower the cut-off frequency of bass - 3DB is, and the richer the upper and lower sounds are. Although 5 inches did not reach an ideal state, I was relatively satisfied.

▼ Kaifly's front grille is OK Uncovered , when opened, we can see it A number of pronunciation units are evenly arranged on both sides of the middle display screen: 3-inch left midrange speaker 1, 1-inch left tweeter speaker, 3-inch left mid-range speaker 2， Left phase inversion Hole, display panel, Right inverted hole, 3-inch right mid-range loudspeaker 2 1 inch right tweeter, 3-inch right mid-range speaker 1 。





▼ We can see from the mid-range unit and the tweeter membrane ball that the workmanship is very fine and the quality is quite guaranteed.

▼ In terms of attached accessories, there are remote control * 1, cross screwdriver * 1, two No. 7 batteries, HDMI HD cable * 1, optical cable * 1, one minute two AUX audio cable * 1, double lotus audio cable * 1, USB cable * 1, and several instructions.

▼ Kaifly's remote control has to be said that it really matches the audio system. It is very heavy and feels good when holding it. The remote control can be divided into power, audio, video, input, mode, direction and volume keys from top to bottom. The buttons are made of metal material, which makes a "cluck" sound when operating. Because the remote control is large overall, the operation of ordinary children will not be smooth. The remote control uses frosted baking varnish, which is slightly slippery in the hand.

▼ Compared with the common remote control, Kaifly's remote control has a little trouble replacing the battery. It needs to use a screwdriver to remove the two screws at the bottom, and then remove the backplane to install it. Although it is also very fast, it will be a bit troublesome if the screwdriver cannot be found? Fortunately, the batteries of the remote control can last for half a year, so they don't need to be replaced frequently.



▼ In terms of system, Kaifly adopted Realtek 1185 chip, a chip from Ruiyu Company, is very classic The field can be said to occupy most of the country. The HD decoding ability was very excellent, and the DIY was very high at that time. After starting up, I saw its UI interface, which is really friendly. The interface is clean and simple. Compared with the current Android system interface, the operation is more intuitive and faster. There are five main menus in a row, namely "File Management", "Movie", "Picture", "Music" and "System Settings".

▼ In the system settings, it is divided into "system", "network", "sound" and "video".

▼ Kaifly has very rich EQ settings, but why not display them in Chinese? I don't read many books. Some of them are really incomprehensible.

▼ In HDMI and S/PDIF fiber output Kaifly supports LPCM and source code output.


▼ 5.1 channel and HD sound effects are supported in surround sound effect settings.


▼ Kaifly does not support internal hard disk, so it needs to connect external storage devices through USB. In file management, when a USB device is connected, it will automatically switch to the management interface. Here, there is a large slot that needs to be improved. If there are too many files in the USB device, the system will take a long time to read. When the circle in the lower right corner rotates, the system is in a suspended state, and the remote control operation is invalid. The system has to wait for the completion of disk reading.

▼ The system supports the normal display of multiple partitions of hard disks, and can correctly identify multiple hard disks.

▼ When the movie is played, it is estimated that everyone is used to dragging the progress bar directly now, but Kaifly does not support it. It can only adopt fast forward and fast backward, and it does not support time node selection. Although this is slow, it still supports 32 times speed.

▼ Kaifly supports fast switching between subtitles and audio tracks. The remote control is also equipped with corresponding shortcut keys.

▼ While supporting Blu ray ISO files, Kaifly also supports the playback of original Blu ray discs. However, it cannot directly play the original Blu ray disc folder. Instead, click the video playback button on the remote control in the folder interface.


▼ For external subtitles, Kaifly also has very rich setting options.

▼ During the whole local HD video test, Kaifly gave full play to Realtek 1185 chip has excellent local decoding capability, whether it is a Blu ray ISO file or a Blu ray original disk file of up to 60 gigabytes, or a 1080P video file of about 10 gigabytes, Kaifly can be said to be all right. Realtek 1185 chip can decode all video files of 1080P and below, H.264 and below. Although it is a pity that 4K and H.265 codes cannot be decoded at present, it is absolutely enough in the last two years. Broadcast demonstration of the Blu ray version of Titanic:

▼ Presentation of Immortal in Blu ray ISO format:

▼ Presentation of the original format of Blu ray "The Prophet":

▼ Play demonstration of Ice Age 4 in 1080P format:

▼ 1080P TS format "The Second Coming of Christ" broadcast demonstration:

▼ But for HD enthusiasts, it's a pity that Kaifly does not support Blu ray navigation. If such a good speaker could be equipped with a SIGMA chip that supports Blu ray navigation, I think the effect would be better. Although it is said that Kaifly does not support Blu ray navigation, but I tried DVD 9 ISO file navigation. It still supports Blu ray navigation.

▼ In the file management, we can read the shared files in the NAS in the LAN through the network, UPNP or NFS. The operation is very simple. Open the search directly.



▼ When playing network shared video files, you can manage them like local files, including adjusting external subtitles, switching audio tracks, and fast forward and fast backward.

▼ In terms of audio playback, Kaifly supports most popular formats on the market, including wav mp3、ape、ogg、dts、flac、aac, And the cue list.

▼ The music playing interface is slightly simple, with playlists on the right and album covers and related information on the left. In addition, Kaifly supports automatic searching and playing music when you start up, so if you just want to listen to music, you don't need to turn on the TV at all, just turn it on Kaifly.


▼ In terms of power consumption, The power of Kaifly is about 0.9W/h in standby mode, 17.6W/h in no-load operation mode, and 20.7W/h in the case of an external 320G mobile hard disk. In addition, as the volume increases, the power consumption increases gradually.


▼ In terms of use scenarios, Kaifly can be used alone or connected to other players and TVs. I will briefly introduce it here. Kaifly is a box+audio integrated machine, which can play audio independently. You only need to connect it to a USB stick with music. Then turn on the power, Kaifly can automatically search the music files in the USB stick to play automatically. We can play/pause and switch through the audio control area of the remote control. In addition, Kaifly supports Dolby TureHD and DTS HD Master 7.1 channels, and supports lossless music formats.

▼ In addition to independent operation, we can also directly connect it to the TV When Kaifly comes to play, the remote control selects the unit, and it becomes a high-definition player and HIFI audio. Of course, we can also Kaifly becomes an independent TV audio, and only needs to set the optical fiber output. Of course, if you want to add a player like me, it is also possible. The player outputs video to the TV through HDMI, and audio to the TV through optical fiber Kaifly.

▼ In terms of playing mode, Kaifly has four modes: HIFI, movie, music and news. Each remote control has a separate button to facilitate users to switch at any time in different environments.

▼ On the bass selection, Kaifly supports five levels of adjustment.

▼ Except that the USB flash disk plays automatically, Kaifly also supports the AUX playback mode. You can connect the audio to your phone, tablet or other playback devices through the AUX audio cable. Use the remote control to adjust the audio to the AUX mode to play the music files in your phone.

▼ In addition, we can also AirPlay and DLNA technology to realize mobile phone and The mobile internet of Kaifly audio terminal can make the audio jump at any place in the home as long as there is network.

▼ At the same time, we can also use AirPlay image and DLNA can push any content on the mobile tablet to Kaisfly， It includes music, photos, videos, and we can play games on our mobile phones and display them on the large screen.


▼ Under test In Kaisfly's high school, low frequency and sound quality, I selected two representative films and TV plays: Saving Private Ryan and Tiger Tiger, sneak attack on Pearl Harbor 》, and two singers I like very much, Cai Qin and Zhao Peng. Cai Qin's songs are very pure and suitable for testing vocals; Zhao Peng's song is an excellent choice for testing bass.

▼ We all know Saving Private Ryan and Tiger Tiger, sneak attack on Pearl Harbor 》These two films are war movies, in which there are many sounds of aircraft flying, bombing, blasting, machine gun strafing and bullet case landing. The scenes are grand and the levels are complex. adopt Kaifly can bring a very real sense of presence. Of course, I have no experience of going to the battlefield personally. I said that the true sense of hearing is nothing more than the sense of film and television. especially The battle at the beginning of Saving Private Ryan has a strong sense of hierarchy. The explosion in the distance, the sound of bullets breaking through the helmet near, the commander's cry, and the wailing of the wounded beside. We can clearly identify the position of each sound. The stereo surround sound effect does sometimes give me some illusion of presence, but it is quite different from the real 5.1 sound field layout.

▼ I always think that a good speaker should be "true, accurate, natural, without modification". Listening to Cai Qin's Forgotten Time, Ferry and《 Moonlight Serenade, I really felt the emptiness of that kind of music. I sat on the sofa, closed my eyes quietly, listened to Cai Qin's song slowly, and was a little touched. Some people may say that Cai Qin's songs are very pleasant to listen to in any box, and there is basically no problem with them. There is basically no obvious defect in the mezzo tone. I have no objection to this statement. It's really good for me to listen with my mobile phone. Friends who have heard of boxes of more than 100000 grades must be disdainful of this kind of box similar to the echo wall, but we have found its position, naturally speaking from that angle, you will find it is a good product.

▼ After listening to several songs by Zhao Peng, I feel Kaifly still needs to improve in terms of bass. The sense of volume is slightly insufficient, and the dive is not in place. There is no obvious difference by adjusting the bass frequency. The overall outline is not clear enough. Of course, this subjective sense of hearing is always affected by personal emotions.


After a week's trial, let's make a final summary, that is, some use feelings. Kaifly has excellent high-definition decoding ability in local broadcast, but at present, Realtek 1185 chip inevitably lags behind. Although 4K and H.265 are not popular at present, I think most consumers are still reluctant to pay for the old chip. In terms of sound quality, it is not very good, but in general, positioning in the level of family leisure and entertainment is absolutely enough. The system interface is simple and clear, but sometimes the operation is sluggish. Especially when the storage device is connected for the first time to read data, the long waiting time will cause great dissatisfaction of users. In addition, I personally think that in terms of system, it will be more acceptable to choose the current mainstream Android system with the latest Hisense chip!
