This site is the first sun to carry non-destructive little music library - remember CAYIN Kai sound I5 lossless music player to get started listening

I. Introduction

As a portable anti-burning party, he hasn't paid attention to the portable player for several months. Since he had gone feverish, he has been adhering to the "many-thought concept of the Walkman." (Just kidding, but there's nothing comparable to big-eared players.) , concentrate on playing big ears. The hand is also leaving only a few fever plug, as the front end, millet note top version (9018c2m independent dac) + Xduoo xd-05 (portable decoding amp), basically solved my listening and speaking requirements on the way to work and office .

However, some time ago, a new country brick attracted my attention. The old audio manufacturer Kaiyin released a portable player based on Android system - the Kayin i5. Speaking of the Android system portable player, before the basic foreign products, such as the sox Dafa's zx1 and zx2, Onkyo dp-x1, Pioneer xdp-100r, etc., there are also domestic professional manufacturers flying proud x7 and so on. However, the Android system player has basically the biggest contradiction: Since it is Android can certainly be connected to the Internet, the user is generally in order to easily listen to the songs at any time, eliminating the need for regular hifi players need to download regularly -> transfer into the player Trouble, but because I do not know whether it is a technical problem, most Android players can not call independent decoding dac in the use of third-party Internet playback software, online listening to the song's sound quality is only equivalent to an ordinary Android smart phone, sound quality is not as good as some Independent decoding dac music phone. Only the songs that are played by the player itself call the independent decoding dac, but the onboard player cannot listen to the songs directly online or it needs to be downloaded into the player. Positioning is awkward.

        Kei Yin i5 read before the introduction and the sea bass music cooperation, comes with the player is a customized version of Haibei, this model can solve the problem of Android hifi player in the end, with this question, I got a I5, through the use of a week, the following to share with you valued use experience.

Second, out of the box

The box reads, "Nice, never the same," How different it can be, or to receive the ear

On the back is written some official parameters, more important points: 1. ak4490's dac, this dac effect is still more like personal, currently used portable decoding amp xd-05 also used this dac, iRiver and home flagship The player is also this dac. Of course, the effect still depends on the manufacturer's skill and collocation, and the sense of hearing cannot be based on chip theory alone. 2.usb3.1 interface, the latest interface transmission speed has been guaranteed. 3. wifi and Bluetooth support, since all Android, it must be supported.

Family portrait, nothing more than anything, some also have, the official sent a lot of film, love or love to protect the machine

The latest type-c interface, also sent an old-fashioned interface Adapter, to prevent the use of mobile phone Data Cable connector can also be used without a connection Cable emergency

Machine with the effect, ah, the work of the country's brick has finally improved

Carbon fiber effect of the back panel, similar to the Kayin n5, always feel the harmony of the back of the AK player, personally feel that perhaps the whole metal may look good

At the top are the headphone port and the amp output port, don't make mistakes, otherwise you understand that the balanced interface is canceled compared to n5, but I haven't balanced earbuds yet.

The volume knob works well, and the rotation damping is moderate (I think I thought about the n5 hard-to-turn turntable and the Shanling m3 spinning loose lighter)

There is only one opening key on the left side, and the right side is the volume and pause/play button and tf card slot. The bottom is connected to the data cable interface. It is similar to the layout of an Android phone. It is clean and easy to use.

Look at the next volume, compared to my millet note is still a lot of small, no pressure on your pocket

Compared to portable amp decoding, it should be lighter

Third, the use of experience

  Since it is an Android system player, unlike the traditional player, the system's experience is still very important, nonsense is not much to say - boot

After booting, you must first register the next member so that you can listen to the song online with the Haibei player.

After registering as a vip member, you can listen to lossless songs in the online music library every month without limit. The download limit is 200 songs per month (600 in the first 3 months).

For Shaoyou, this amount is still a bit small

Similar to Android phones, shortcuts are the most commonly used shortcuts

The music setting options are also very simple, and I don’t even use it for me.

Android is familiar with the settings interface, just got it, of course, to update the system, Android is convenient, unlike the original country to the official website to download the upgrade package

Update to the latest 1.5 firmware and get it!

Install third-party software NetEase cloud and browser below. . . Wait, the royal war Haha, pretend to play and see if it can run

Nothing to visit Zhang Aunt

Netease cloud, listening to one ear. . . Forget (after the sound quality test will say)

-------------------------------------------------- --------- Gorgeous Divider ------------------------------------- -------------------------

Officially entered the use of the player experience. . .

Comes with player interface, the body comes with 32g memory, can be inserted tf card, for me this portable fever when 32g is actually sufficient, and you can also see that you can also connect to Baidu network disk, as long as there is no need to worry about the network Now. Not to mention a huge official library


The official online music library is presented in the form of a single cd. All cd songs are tracked in flac format, which can be downloaded separately or downloaded as a whole CD.

The official distribution of popular vocal, jazz, light music, ethnic, classical types. For me (see my main force is known as the classical party), of course, first go to see the classical music library (⊙0⊙), the trittico, the sunshine Qinhuang, the West Grand Fair. . . All classics in the classical party have

Try the online search again and search for "Beethoven" . There are so many albums to search for "Jay Jay". There are many old albums and the new albums are not seen. It seems that the positioning of this online music library is very obvious. For some classic cds, the number of albums is very large. Some albums on the market or even on the Internet can be found here, but it is relatively slow to update new popular albums. For those who often listen to the latest popular albums, they have to rely on third-party players.

Each album can see the introduction of this album

Can download singles or entire albums from albums

The downloaded songs can be seen in the download management of the personal center.

The downloaded album can be divided into folders, sub albums, or musicians

It looks like a bug has been found here. It looks like the classical style. Others have not been able to automatically assign

Just pick a song, you can see that you can choose different eq, of course, hifi party is never adjusted eq

Another bug, the lyrics do not display correctly when played online

You can view the song information. You can see that the size and bit rate of the online song are all really lossless. If the network is not smooth, it will really be played.

Adjust the volume by using the physical knob or swiping the screen during this interface

Here are some of the shortcomings of experiential discovery:

1. Self-contained input method Since the screen is relatively small, it is difficult to input accurately. It is recommended to install a third-party input method.

2. There are several unresponsive encounters during use, especially when downloading songs in the background, it is easy to cause Caton, especially if you download the whole album with many songs, it is easy to vocalize, and sometimes it even causes the download of songs to fail and you can only download again. (Additional suggestions, the downloaded songs are recommended to be highlighted in the online album again, such as font highlighting, and the songs that haven't been downloaded are distinguished from each other. download)

3. The third point should say that it needs to be improved. Since it is an online player, we hope that we can add the function of commenting on users. It should not be determined whether or not it is worth downloading for a certain album. It is still worth looking at the comments of the people.

The experience of the operating experience is here, and the following is the most important part of the sense of hearing. . .

Fourth, listening to i5's sense of hearing, I hope to compare the three systems:

1. The most commonly used party fever - portable music phone (with independent decoding dac and independent op amp)

2 mobile phone to do dial, connect portable decoding amp

3. Kaiyin i5 push


Through this comparison, it is possible to compare the sound quality differences between the i5 and music headphones and bundled portable amps, so as to find out the correct positioning of the i5.

The song selects the lossless audio file downloaded from the i5 Music Library. The tracks are vocal, classical, and pure musical instruments. ( For the sake of fairness, use the Netease Cloud Player to play local music in a unified manner)

Before the test, I mentioned the i5 mentioned above. When using a third-party player to play online music, the difference between the sound quality and the sound quality of the online music library is an ear. On the one hand, the online audio file of Netease Cloud is not lossless. In order to eliminate the interference of audio files, on the other hand, I used Netease Cloud and my own player to play the same local music. The result of the comparison is still an ear gap. This has to make me guess. It seems that the Android player is The third-party software still cannot support the independent decoding dac ah. Of course, this is my guess. It still needs the official answers and optimization in the future. Fortunately, the music that comes with the official player can also be listened to online, and it is really unscathed. For my classical party, most of the time I still use my own music library. However, this experience is a bit embarrassing for users who often listen to the latest popular albums.

Then say the headset used to compare audition:

1 flat classical plug: Yuyin pk1 Zhang Yang line version

2. Voice into the ear: Jazz x10

3. "Pseudo" push flat big ears: man home he400i


Domestic classical artifact pk1, high impedance, is a test of the front end thrust. The voice of vocal x10 is also recognized as more difficult to wait for a good plug, of course, will not wait for a bad sound it does not. Men's home he400i as a flat big ears, very resistant to the sound, once propaganda can be pushed directly, personal feelings is straightforward will not be a bad sound (similar to the old version of hd650), but want to push good still need some skill. These three headphones can basically reflect the quality of the front-end.


1. Music Phone Direct Push

Xiaomi note top version configuration is 9018c2m independent decoding dac with 4 op amps, so the cleanliness of the sound quality and thrust compared to non-professional mobile phones or promoted greatly. When using the millet note as a direct push front, when the Jazz X10 test vocals, the sound is still very clean background music and vocals have a good degree of separation, but the 9018 decoding has a common problem, that is, more partial digital sound, said popular point That is, the sound is dry and cold, and the dive depth is generally low. Pk1 as a high resistance deities, listening to the classical landscape sound field is very broad, but the mobile phone direct push pk1 is obviously not qualified, first horizontal sound field has a certain degree of breadth, but there is no very loose feeling, vertical flat, low frequency is even more miserable, depth can texture Not reflected. Therefore, music phones directly pushed only x10 to listen to popular still fairly qualified, partial quality sound, feelings are not in place.

2. Mobile phone external portable decoding amp

As a portable anti-firing party, mobile phones are only an emergency solution. In general, I am going to bundle my portable amp. This xd05 uses the same ac4490 dac as the kaiyin i5. This dac I like very much. I don't want to feel the emotional digital sound of the 9018, nor the taste of the cs4398 and lose the hard quality. Through mobile phone otg connection xd05, using Jazz x10 to listen to vocal high-frequency relative to the phone straightforward to increase some moist degree, the frequency of the density is more full, low-frequency texture better, x10 sound field is not large, but still relatively regular The basic push is in place. With pk1 listening to classical and pure music, high-frequency overtones, low-frequency dive has a very significant improvement, the sound field is also relatively open to push the phone directly, simply to be more full. Since the use of a large thrust amp, connected to the he400i is no pressure, the gain can be modulated in the mid-range, flat-panel headphones high-frequency extension relative to pk1 will be more smooth, intermediate frequency density and sound field big ears is even more congenital advantages than Pk1 has a more relaxed sense of hearing, low-frequency volume is the tablet's weaknesses, although the dive is not deep, but the flexibility is good, it is quite satisfactory.

3. Kaiyin i5 push

The protagonist Kaiyin i5, connected to Jayce x10, played a familiar beat it, the background sound is very clean, i5 relative to the original used for some time n5, the purity of the sound has improved, warm thick The style has converged. Compared to mobile phones, there is no need to say anything about them. Relative to xd05, i5's low-frequency depth has been strengthened, the intermediate frequency density is basically the same, i5 slightly less than the degree of looseness is less than xd05. Then pk1 listened to the first Lu Siqing's violin, Zhu Liang, violin strings, gloss and flicker relative to the mobile phone is also an increase in the ear, the background music instrument's sound field is also pulled very loose, pk1 basically no pressure to push up.

Connected with the he400i big ears, chose a large compilation of the Western Grand Album album The Magnificent Seven, push the big ears need to adjust the gain to a high gain, the first sound field relative to pk1 upgrade is still very large, vertical and horizontal support Open, there is no feeling of congestion and confusion, the momentum of large-scale preparation is also reflected better, and the gap is very small compared to xd05, but also only feel a slight disadvantage looseness, after all, the thrust of xd05 is amazing, with the front end can do The thrust to i5 has been able to meet the needs of portable. I would also like to say that the i5's voice tends to be neutral compared to n5, but it is slightly warmer than xd05, and may be related to the tuning style of Kaiyin, but this warm color is acceptable, even if it is classical I feel bored.

4. Supplementary testing

1) Bluetooth test

After testing the commonly used headsets, add the Bluetooth function of i5 under the test. Since I don't have a Bluetooth headset on hand, I tested the Bluetooth function with Philips Bluetooth speakers who had participated in the test of Aunt Zhang.

Turn on the i5 and speaker's bluetooth switch and it's easy to connect and pair.

Using i5 as a dial, you can play or play local songs online, and the speakers start singing. It's very convenient.


2) File Transfer Test

The song can be copied by connecting the i5 to the computer via a data cable. The directory for songs is stored in CayinDownload.

After the 1.5 firmware is updated, the songs will be automatically created. The previous single file was downloaded without updating the system's previous 1.2 firmware, and is obviously more user-friendly after the update.

The speed of usb3.1 is still quite fast, and the writing speed is basically above 20M/s.

Incidentally, there is a problem here. The manual says that the i5 can be connected to the computer as an external dac, but it is found through the connection that it can only be used as an external memory and cannot be used as an external dac. Maybe it's because the official function is not yet perfect. If this is the case, it's urgent to improve the function, otherwise it is false propaganda.

V. Summary

      The Kayin i5 is the second Android system's national tile (If you remember correctly, the first Android country tile is the FiiO x7), which increases the online listening and Bluetooth functions compared to the traditional national tile player. Convenient to listen to songs that are too lazy to pass songs back and forth is an advantage. The online lossless audio library is also the biggest highlight of the i5 (that is, the number of downloads per month is still a little less for download control and favorite control fans) but the current system The degree of completion is still a lot of need to improve and improve the manufacturers, such as the friendly interface operation, the system's fluency, long-term use of the system after the cleaning and optimization, etc., to ensure that the user in the process of smooth and easy to use experience is also In addition to sound quality is an important factor. There are also manufacturers promised to connect the computer to do dac functions, and whether the third-party player invokes the independent decoding dac (this remains to be verified) is also required by the vendor even if the firmware is updated. In general, my position on the Kei-i i5 is a new attempt by the national brick manufacturers in the portable player field to provide a convenient online lossless audio library for the majority of fans (especially the Gospel of the Classical Party).

This time the experience of the use of Kai sound i5 to this matter, here disclosed, the next audio device will bring you a new original domestic gallstones combined with the amp, headset is of course using the new hd800 to test
