New X5 3rd Generation Hot Questions Answering (6th Update)

Hello, everyone,

X5 has received extraordinary attention since it was released and listed. On the one hand, the product has been recognized by everyone, on the other hand, it is also because of too much attention, and some of our own preparations are still not perfect. Therefore, we apologize for bringing some trouble and inconvenience to everyone.

In order to better communicate with you and let you know our products better, we will briefly explain and explain the problems that have occurred in the past few days.

1. Some questions about JD.com's initial sales and activities.

this problem, our agent has already made some explanations. For details, please refer to the statement on JD.com's initial launch.http://tieba.baidu.com/p/4906093996;

, I would like to add here that many people are not very clear about JD.com's operation. By the way, JD.com's sales are actually divided into several types:

A, JD is self-operated, including:

A1, Jingdong sales, direct supply from manufacturers;

A2, Jingdong sales, direct supply by agents, manufacturers do not correspond to Jingdong.

B, third-party self-management, including:

B1, the manufacturer directly sets up shop on Jingdong;

B2, agents directly set up shop on Jingdong.

the current sales of Feiao on JD.com belongA2this situation.

Jingdong is self-employed, manufacturers and agents are only suppliers in principle, and the seller is Jingdong. Therefore, suppliers cannot control many things. This time there was sales before 10:00, which is the case.

In addition, the starting event is also planned by the agent, and we assist in publicity. Because normally speaking, we have more than 60 agents across the country. If it is a manufacturer's activity, then the agents are all participating in a unified way. There is no reason why JD.com does not engage in other manufacturers.

, therefore, we are not responsible for some things that happen in the activity.

In addition, please remember that the so-called "Feiao customer service" on JD.com is not our customer service. At present, our official customer service only provides services through 400 phone number, WeChat's official public number, Weibo's official account number, Feiao Post Bar, and Feiao customer service in the earphone community.

, we will also review the activities of agents to help them simplify the operation as much as possible and reduce the trouble of customers.

Of course, I also hope that everyone understands that the agent's original intention is good, and there is no intentional black box operation or unfair.

2. About the noise mentioned by individual users in the earphone world.

First of all, this user is compared with our X7. Due to different product positioning, audio performance X7 is much higher than X5 (3 generations). Because X7 uses higher performance ES9018S and better op amps. One cannot expect X5 (three generations) with a price of only more than half of X7 to surpass X7.

secondly, compared with other products of the same level, the bottom noise of Feiao's player has always been well controlled. We can't say that we are the first, but we can compare the competition by ourselves, which we can't cheat everyone.

In addition, third-party evaluation organizations such as earphones will also conduct objective and fair tests on the products. The bottom noise is an objective audio parameter, and the size will be known as soon as it is measured. You can also compare yourself. On this issue, manufacturers cannot fish in troubled waters.

, because our shipments on the first day are very large, we will not pat our chests to make meaningless guarantees as to whether there are very few differences. But some remarks must be exaggerated, please identify them yourself. In a word, I suggest you go to the physical store to audition.

3. About the fact that the TF card adopts Cato design, which leads to the user's misoperation.

adopted the hidden Cato design with better unity and better appearance on the X5 3rd generation, which is a suggestion put forward by users. We have also undergone a careful evaluation. Considering that smart phones have been imported from the iPhone, users should already be very familiar with and understand the relevant operations. That's why we imported this design on the X5 3rd generation.

, you only need to pay a little attention and don't need to worry too much. Of course, we welcome everyone to give us feedback on whether Cato design is good or not so that we can adjust the new products.

4. Regarding individual usage operations and random bugs, the user asked why the sales were not completed and why the firmware was upgraded as soon as the sales were completed.

First of all, the prototype of the X5 3rd generation was available in August and tested by internal users since September. Moreover, the X5 third generation firmware is based on X7 3.0 firmware, which has been iterated to 3.0.11 on X7. Has gone through many rounds of internal testing, public testing. There is basically no problem.

However, due to the complexity of intelligent operating systems, one of the major benefits of adopting intelligent systems is that new functions can be continuously provided through firmware upgrades. Therefore, the current mobile phone/smart hardware is continuously improved and upgraded throughout the life cycle. Even Apple is the same.

Therefore, it is completely impossible to go on sale if there is no problem at all.

5. Why is RK3188 still used as the main control chip.

to put it simply, we have no other choice to be an Android smart player. This is not just us. You can look at the domestic player. There are only two kinds of chips back and forth, either RK series of Ruixinwei or Junzheng chip.

if you want to use Qualcomm, MTK and Samsung chips, it is not just an entry fee/development fee. The most important thing is that the original factory will not provide technical support to any one in the player industry. Without the technical support of the original factory, even if it is done reluctantly, some problems can not be solved later to get the technical support of the original factory. Because many functions and BUGS must be improved by the chip factory from the bottom, not something we can solve.

In addition, South Korean players generally use Telechip master control, and their performance is far from that of Qualcomm/MTK/Samsung, and they are both South Korean enterprises. Why not use Samsung master control so far? In fact, the reason is the same. The entire player industry, Japan, South Korea, the United States, China, all combined. It is not enough to sell a model of a certain brand in the mobile phone industry.

6. Why use 1G RAM instead of 2G or higher.

this is after X7 sales and actual feedback, the player is mainly used for music playing, and 1G of memory is completely enough. If 2G is added, it will lead to an increase in costs, etc.

7. Does the X5 3rd generation really have typing cards as some people say?

X5 3rd generation built-in Pinyin input method, switching to Chinese will affect the sound effect, as long as the sound effect is turned off, it will be normal.

8. X5 3rd generation put it in the bag to listen to fever?

this is determined by the conservation of energy in physics. Any object that can generate heat will accumulate heat in a closed space and cause the temperature to rise. Pay attention to the use environment. In addition, even if heat is generated, it will not cause safety problems. There is a temperature protection circuit inside the machine.

9. Why do TF1 and TF2 copy at different speeds in the third generation of X5?

Because RK3188 has limited universal communication pins, only two standard modules can be externally connected, one of which is occupied by wifi/Bluetooth module and the other by TF card. This is also the reason why X7 only supports 1 TF card, and similar products only use 1 TF card.

However, through the efforts of engineers, in order to continue the X5 dual-card design, a chip was added to the X5 third generation, thus successfully expanding an additional TF card interface, and also bringing the additional benefit of the TF card slot faster.

Of course, adding this card slot also brings some minor problems, such as increased power consumption of the whole machine, for example, some small software bugs cause standby to fail to wake up. However, the software problem has now been solved.

10. The progress bar does not leave when NetEase Cloud Music is playing.

this is the latest version of Netease cloud music and system compatibility problem, we suggest that if you need to install a third-party music APP, please go to our built-in feiao market to download and use it directly.

The same is true for other apps. Generally, apps built into our official app market have been tested for compatibility.

11. Cool My Music Box cannot be played.

Currently, it is recommended to download the Kuwo music box directly from Feiao Market. It is also supported after upgrading the Kuwo music box online.

12. Update the music library.

① Why do you sometimes update the song library to display "update 0 songs"

X5 uses an incremental update method. If the song has been added to the song library last time, it will not be added this time. Therefore, there will be "0 updates". This does not mean that the update failed.

incremental updates are used to support the "latest addition" function, which also saves the problem of slow and long time for each update from scratch.

② Why is the number of updated songs wrong?

Currently, CUE updates are calculated based on Android 1 song (X5II is calculated based on the number of singles in the sub-track). If you think the number is wrong, you can check whether the total number of tracks is the same as before under local music-> all songs. If there is still a missing song, you can go to the internal_sd-FiiOMusic-crash to find the latest logForScanProblem file and send us the problem tracks mentioned in it for analysis and processing.

Note: If the music library update card machine appears, please send us the entire folder of crash(internal_sd\FiiOMusic\crash).

(3) Why can't ISO tracks be scanned to the song library?
This is already being processed, and the firmware version will fix this problem later.

13. The slow response of Feiao market.

this has been planned to improve.

14. Some netizens reported that the audio performance of X5 generation is not as good as X5 generation.

X5 third generation uses different chip and circuit designs to increase the balanced output. The audio performance is basically at the same level as the old X5 second generation. Some indexes X5 second generation are high, and some indexes X5 third generation are high. However, the listening sense, function and design have been greatly improved. It is unrealistic to expect earth-shaking change.

Of course, if you prefer the simple small screen, the solid turntable design, and the old tuning, you can still buy the X5 second generation normally.

15. Small bursts in individual cases.

this is because one of the core performance of HIFI music player is to support music playback in various streams and formats. The DAC chip needs to reset the chip settings when switching different sampling rates. At this time, there is a slight sonic explosion caused by DAC restart. This problem has always existed. If only like Apple's itune, all songs will be converted into standard formats and sampling rates on the computer before being imported into the player, but this will lose the greatest advantage of HIFI music player.

of course, we will continue to improve this problem.

16. Occasionally, small bursts occur when the power is turned off.

this problem is because we have always used mechanical relays as the protection circuit for switching on and off, and avoid switching on and off noise by disconnecting the physical connection.

, however, this method has several disadvantages. One is that when the relay itself makes a drop of sound when the machine is turned on and off, the user thinks that there is a problem with the machine and the user experience is not very good. Second, the relay cannot completely eliminate the pop sound of the switch, because the contact will generate pop sound when it is closed. Third, the large size of the relay takes up valuable space.

Therefore, we have adopted other methods to solve this problem on the X5 3rd generation this time. In the process of using, you can pay a little attention not to turn on and off when you are wearing headphones, but the sound of turning on and off is not big.

17. The key is prone to misoperation (for example, the scroll wheel plays the pause key).

We recommend that you upgrade the firmware to FW1.0.6. In this firmware version, the lock screen mode has been added.

18. Is there a fast charger? Is there a warranty on the charger?

Yes, we have a fast charging charger for JDB (currently only in the mainland market). Please pay attention to inventory when you receive the goods. The fast charging charger is packaged separately. The charger is guaranteed for one year. You can contact according to the after-sales address of JDB in the charger package, and attach a small note stating the reason for the warranty and the receipt information of the replacement. You can also choose to contact us or purchase the seller for warranty.

19. Statement on Newly Added Viper Sound

Recently, we have added viper sound effects to the latest firmware of X7 and X5III. In order to let everyone better understand and use viper sound effects, we will make some explanations for some questions.

A, what's the use of viper sound? Will it affect my sound quality?

Viper sound effect, as its name implies, is a kind of sound effect, that is, EQ, which is commonly known to everyone. It is more interesting functions that we practice "unlimited music". You can adjust the corresponding sound effect settings according to your own preferences to achieve your favorite experience. Of course, if you don't like this function, you can also choose to disagree when clicking on the viper sound effect.

B, why do Viper sound effects charge?

Viper sound is a product of the hearing workshop. In order to bring more interesting functions to everyone, we have introduced the sound effect in cooperation with the hearing workshop. In order to bring more benefits to everyone, we have worked hard to win seven free sound effects for everyone, and the remaining deeper experience requires everyone to pay for it. The provision and benefits of viper sound effects are all auditory workshop companies, and Feiao acts as a platform to bring different experiences to everyone.

C, why do Viper sound effects need to be connected to the Internet to use?

Since some sound effects are used for payment, it is necessary to check whether they are paid users for the first use of each startup (the network can be disconnected after WIFI verification is turned on); Of course, after we communicate with the auditory workshop, we can use it without networking.

D, I bought viper sound effect on X7, can I use it on X5III? Will you need to buy it again when the official version is released?

, I'm sorry, the payment for Viper sound only supports the paid device, and the new device needs to be paid again. However, the firmware update does not need to be repurchased, and you can use it with confidence.

E,At present, the purchase of Viper sound effects is the only corresponding to the SN code of the body. When the viper sound effect has been purchased, if there is a change of machine, how can the user reuse the viper sound effect purchased before?

we have already communicated with Viper Company and need to provide the purchase payment account number, payment time and SN code of the existing machine, Viper Company can help adjust SN code. Therefore, users can contact us to deal with this situation.

F,I bought the viper sound effect, but even if I re-set it, it will not take effect?
For this situation, you can contact us (marketing QQ:4000026846,QQ search service is enough), and provide the SN code of the machine and the payment transaction number (generally, Alipay/WeChat payment is 28-digit payment order number, PayPal payment is 17-digit transaction number), and we will contact Viper Company for processing as soon as possible.

20. Why is the X5 3rd generation balance port a little smaller than the single-ended output power?
this is because when designing the X7 AM3 module, our first product with balanced output, we found a rather embarrassing thing. if we follow the normal and simple design, the balance should be more than double that of the single end (theoretically it should be 4 times the power). however, if we design it like this, if the single end should maintain a better thrust, such as more than 200mW, then the balance will be more than 400mW.

this will cause heat and power consumption in balanced mode to be very large, sacrificing some user experience. However, if the balance is 200mW, the single end will change to about 100mW, thus the single end thrust will be too weak. So the trade-off is repeated, and we're still designed to have the same balance and single-ended output power.
In addition, the balanced output of earphones is strictly BTL output circuit, which was commonly used in multimedia speakers and car amplifiers. Because the advantage of BTL is that under certain conditions of power supply voltage, it can output higher power than single-ended. But on the player, it is not necessary to balance the power. (The car is limited by the level voltage, and the multimedia speaker is because the IC cost is high after the power supply voltage is high).
In turn, the biggest advantage of balancing on the player is that the BTL output has no ground, which can solve the problem of low separation caused by single-ended left and right channels.
single-ended output is, the left and right channels take different DAC output and filtered signals, and the specific architecture is the same as many similar products.

21. The problem of weak WiFi signal.
According to our test results comparing X5III and mobile phones, there is little difference in signal strength. It is recommended to download and install WiFi analyzer app in Feiao Market to test the signal strength of X5III's current WiFi.
Similarly, this WiFi analyzer can also be installed on the mobile phone, compared with X5III, and then the test results of the two, the model of the mobile phone, the model of the router and the distance from the router are told to us for our analysis.

22. Why can't Cool Dog Music be installed?
Since the service of Cool Dog Music will always start, even if it is forcibly stopped for a while, it will start again, resulting in X5III being unable to enter standby and consuming a lot of power, we temporarily blocked the use of Cool Dog Music and opened it after subsequent optimization.

23. Why can't pure tone mode use third-party input methods?
In pure tone mode, all third-party services are disabled, and only the system and FiiO Music services are retained. Therefore, all third-party applications in pure tone mode cannot be used.

24, why do I automatically update the song library after waking up on standby? Sometimes the ES file manager pops up?
this is a known BUG and is being processed.
We recommend that you update the music library to manual, use the pre-installed ES file manager, and do not upgrade the ES file manager.

25. Why did I fail to upgrade the firmware?

Currently, X5III supports TFcard upgrades in FAT32 and NTFS formats. Please copy the downloaded firmware (do not decompress) to the built-in storage or TFCard 1(FAT32 or NTFS format). Select the firmware in the corresponding path and click Upgrade.
Note: X5III also supports OTA online upgrades. Make sure that the WiFi connection is normal, and then download the new firmware online for upgrade from the "Technical Support-Firmware Upgrade-Online Upgrade" on the desktop.

26. Does X5III have USB Audio?
Currently, USB Audio only supports some devices and is still being optimized.

27. The playback progress bar is moving, but there is no sound in the output?

, this is because there is a bug in the synchronization of the playing state between MCU (MCU) and the main control. Sometimes the main control is in the playing state, but the state is not successfully synchronized to MCU. MCU will automatically power off after waiting for timeout without detecting the playing state, causing this problem. At present, this problem occurs with a small probability. If you encounter this problem, you can try to return to the home page of FiiO Music APP to see if it can be restored. If not, please close FiiO Music APP for 30 seconds before restarting the APP, or restart X5III to resume.

, our engineers have tried their best to solve this problem, and then upgrade the X5III firmware.

28. How do I provide a fault record?

first set X5III to storage mode, then connect the computer through USB (it is recommended to use the micro USB cable equipped with X5III), find the crash folder (internal_sd\FiiOMusic\crash) in the built-in storage, and then send the entire folder to us.

29. Questions about Google Play

After some apps are installed, you will be prompted to upgrade the Google play service. It is recommended not to upgrade Google play service for the time being, and try not to install third-party apps outside Feiao market, because some apps and systems still have compatibility problems. We will try our best to optimize in the future.

30. Why is the song head skipped for a few seconds when playing a song?
According to analysis, this phenomenon is related to viper sound. It is understood that the viper sound effect needs to put the data into the buffer for analysis before corresponding processing can be carried out, which leads to the phenomenon of word drop in the curve head. Please try to turn off the viper sound effect and listen to it again. We have already communicated with viper company.

31. X5III?
The vehicle mode of X5III has not been implemented yet, and this function will be added to subsequent firmware.

32. The bottom noise of the balanced output is more obvious than that of the 3.5mm single end?
In order to obtain the best sound quality effect, on X5III, we did not adopt the DAC integrated digital amplification ear amplifier scheme commonly used on mobile phones, but adopted the traditional analog circuit design with low integration, complex circuit and large amplification factor.
Therefore, WiFi is easy to interfere with the internal analog circuit through space radiation, power conduction and other forms. Moreover, the balanced output is a four-way operational amplifier. After WiFi is turned on, the bottom noise of the balanced output will be slightly larger than that of 3.5mm single-ended, which is also normal.
But generally speaking, this Wifi noise will be masked when playing music. So at this time, you can try to turn off WiFi to see if the bottom noise still exists.
, we have also compared and tested products of other brands, and the results are similar. In addition, compared with products at the same price, the bottom noise of X5III balance is relatively small.

judge whether it is normal WiFi interference or abnormal WiFi interference? Here is a reference range for everyone:
large earphones or low-sensitivity non-in-ear earplugs can be clearly heard. In case of the above situation, you can contact customer service and return to the factory for testing.

33, why does X5III have no coaxial output when it is used as DAC?

X5III is used as an external DAC of the computer, coaxial output is not supported because USB DAC and coaxial output use different audio channels. In addition, using X5III as a computer DAC and then outputting from the coaxial, is equivalent to directly transmitting the digital audio signal output by the computer to the coaxial decoding device, so using X5III is of little significance.

34. How do I export playlists in X5III?
can find the FiiOMusic folder (internal_sd\FiiOMusic) from X5III's memory, then copy all playlist files (.cfg) in the folder, such as "my favorite" (Favorites.cfg) or other newly created playlists, and save them to the computer. In this way, even after resetting the song library, you can copy the playlist file to the same storage directory location of X5III, and then continue to use the previous playlist to play songs. Note, remember not to change the location of the song, otherwise the backed up list will not find the song.

the physical key function of 35. X5III cannot respond correctly on some third-party apps?
X5III (and X7) are made according to the definition of Android system, and the event response of third-party APP to calling system keys is defined by itself. Some APP will be incorrect because it responds to other events when calling the system key (at present, it is found that most APP can respond correctly). We cannot change these definitions of third-party apps, so the play/pause or up and down buttons of X5III cannot operate normally on these apps. (Third-party app can be used normally on mobile phones, because most mobile phones only have volume button adjustment.)

, we will always take customer orientation as the principle. We will accept and improve the feedback questions and suggestions with an open mind. Please rest assured!
