's a small revolution in the country, counting the new features of Feiao X5iii.

For a long time, many national bricks have given me the impression that they emphasize sound quality and ignore the appearance and control of a kind of niche products. There are also many slots to talk about. Fortunately, the majority of burn friends have a very inclusive heart. As long as the sound quality is in the past, despite the exotic appearance and control, they will always be happy to accept it. In fact, this situation is not because the burning friends do not have higher requirements, but the attitude of toothpaste-type manufacturers is more common in the national brick industry. Of course, there will occasionally be a player who does not play according to the routine. Feiao put all the big moves on the X5 3rd generation, piling up many real (flower) use (whistle) functions with unconventional effects.

compared with some manufacturers with traditional HiFi pedigree, Feiao still has certain differences in product design ideas. Always cater to the trend and add some fashionable and fun functions to make the original dull national brick more fashionable and easy to use. This time X5iii introduced functions such as Android system, Bluetooth, wireless, fast charging and dual memory cards, which seem to be very trendy on the national brick, and solved many pain points in the past. Even with the addition of many new features, X5iii did not have too much premium, and the official price of 2498 yuan is still relatively kind.

Although I am not a core theorist, there is no denying that the quality of DAC is also a foundation. DAC is like ingredients, and tuning is like the cooking process of a chef. Only with reasonable peripheral hardware can ideal sound performance be obtained. X5iii took the lead in trying the DAC scheme of double AK4490 in the price range of 2000~3000, which belongs to the higher specification hardware configuration in the middle-end national brick. In terms of quality, AK4490 has 112dB low distortion, 120dB signal-to-noise ratio, 32bit/768KHz hard decoding capability, and high code streams such as DSD64 and DSD128 have no pressure.

national bricks seem to prefer AK4490 DAC. Shanling M5, Kaiyin N5 and Kaiyin I5 all use one each, while X5iii uses two artifacts like AK380. In terms of division of labor, the two AK4490 chips are each responsible for a single channel, which has a very positive impact on the overall improvement of the sound field and separation. In addition, X5iii also uses the line architecture of dual active crystal oscillators, four-way LPF OPA1642x2, and four-way earphone OPA426x2 to escort the sound, and can output 260mW of power under 32 ohms load.

X5iii has undergone most changes in the design language, which has changed the style of X5 and X5K gas stove. With the addition of Android, a larger touch screen has replaced the traditional turntable and keys. The appearance of the previous two generations is completely invisible, but closer to the overall layout of the flagship X7. However, compared with the slightly monotonous appearance of the X7, the X5iii pays more attention to the polishing of details, making the fuselage outline look more three-dimensional and hale. However, it seems that I can see some shadows of AK's products next door. I personally don't dislike "a big copy of articles in the world" for mutual reference. As long as the facial features are reasonably matched, it will be OK.

the titanium X5iii in my hand is the earliest version on the market, Feiao later introduced black and SAO red. The performance in terms of workmanship and materials is satisfactory. The aluminum alloy body is quite textured in hand, and the surface looks very delicate after delicate sandblasting. The front screen is a 4-inch IPS screen with a resolution of 480 x800. There is still a big gap between the display effect and the mobile phone. The fineness is insufficient and the color is stiff. However, it is already very high when it comes to the national brick circle. After all, the national brick focuses on the sound quality (this reason is far-fetched). The back uses a glass cover with a color similar to the fuselage, and the surface is also printed with fine decorative patterns.

Feiao, as a "big accessory factory" in the Jianghu, is by no means a false name. The accessories provided are not only of various colors, but also of unambiguous quality. Accessories include: clear water protective cover, PU protective cover, Micro USB charging line, coaxial conversion line, and a QC2.0 fast charger is also very kind to be sold in China. That's all the necessary accessories for daily needs. In addition, the front and rear films have been pasted when leaving the factory, and the front film is 2.5D tempered film, and the corner is also pasted with a striking Hi-Res certified gold logo.

X5iii's overall keys and interfaces are distributed around the border. This layout not only looks very orderly. The interface is also quite complete, with conventional 3.5 earphone port and Line out interface, as well as the 2.5mm full balance output favored by high fever users. Unfortunately, this baby still has no 2.5mm balance wire on the tall, so it seems that buy buy will have to buy it later. Line out is a multiplexing interface that can output digital signals to desktop decoding through coaxial patch wires in addition to hopping ear amplifiers. It is also quite good to use X5iii as a turntable and connect it to Ober D6 decoding at home.

Of course, X5iii has many interesting functions. The Micro USB interface at the bottom has the function of USB DAC and can be used as an external sound card for notebook computers. The Bluetooth function supports aptX coding transmission, which can better meet the wireless transmission needs of high-quality music. If there is a Bluetooth speaker and Bluetooth headset in the home, you can enjoy wonderful music freely using X5iii, which is also a relaxed and comfortable thing.

X5iii has a built-in 3400mAh battery, and the measured normal volume endurance can exceed 10 hours. The fast charging capability is definitely a big benefit. In my opinion, it is more meaningful than a large-capacity battery. When the power is in a hurry, it can also take a shorter time to quickly recover. The random fast charging plug is divided into 12 V1.5A \9v2A \5v2A multi-gear output power, which can be filled in a little more than an hour and a half. if I remember correctly, X5iii should be the first product with fast charging.

can be said to be the most design place for X5iii. The cutting of those lines is the key to supporting the color value. When the left hand is held, the thumb can fall on the volume knob at the recessed position, which can be conveniently positioned in a dim environment. The play/pause above the volume and the track switch below are all within easy reach of the thumb. The edge of the volume knob is polished very delicately, but the size of the knob is a little small, and the paragraph feeling is not too strong. When adjusting the volume, the hand feel is a little fuzzy.

switch/screen lock key is located on the right side of the fuselage. The decorative elements of the red circle can also be seen on some recent Feiao products, which are becoming a family gene of its products. There is also a blue indicator light in the center of the key, which is convenient to judge the working state of the machine when the screen is turned off. However, the response of the power-on key is a bit slow, and it takes a few seconds for the reaction indicator to light up when starting up, which makes people feel a little uncomfortable.

the two card slots located under the switch lock key, my first impression was "double card and double standby". However, the two card slots of X5iii are used for TFC cards. The maximum capacity of a single card is 256GB, and the two cards can be expanded to 512GB when combined. This is definitely a blessing for fans who have a large amount of master music or DSD large-volume music in their hands. In fact, X5iii itself has 32GB of storage space built in. If the demand for space is not too strong, it is almost enough to put some APE and FLAC lossless files at ordinary times.

non-intelligent operating system is a big pain point for many national bricks. Think about the operation interface of some products. Nowadays, more and more national bricks have begun to introduce Android system. Feiao has also tested Android on flagship machine X7 and brought it to X5iii. Although I can't compliment the beauty of the customized Android 5.1 system, the rationality of the function and the overall completion are still relatively good. The Ruixin micro rk3188 processor used, with 1G of running memory, can basically ensure smooth interaction. The biggest advantage of Android is that it can collect many high-quality music apps through WiFi. Of course, there is not too much pressure to run some commonly used news and social apps. If you want to play games, I can only say that you think too much.

system is no different from common Android devices in use. In addition to the ordinary Android mode, X5iii also prepares a simple pure tone mode. In pure tone mode, it is actually only running Feiao's own player, which is very suitable for those who like simple and pure operation interface. The default player has rich functions but is not cumbersome, and the hierarchical design is clearer. A powerful viper sound effect is also integrated inside, but there are many functions that need to be paid for. Some netizens spent tens of yuan to light up all the functions, which is not too expensive.

use is that many deeper settings are concentrated in the drop-down menu on the main screen. For example, WiFi/Bluetooth switch, mode switch, Line out function switch, high and low gain adjustment, filter setting, storage of Micro USB interface or USB DAC switch can all be easily selected and operated. The five digital filter modes provided are relatively rich, including: steep drop, slow drop, short delay steep drop, short delay slow drop, super slow drop, which can be selected more delicately according to your own preferences.

a good daughter-in-law is "to go up to the hall and down to the kitchen". The player cannot only have a beautiful face. Whether the sound is good or not is the most important thing. Thanks to the DAC scheme of double AK4490, the overall information of X5iii sound is still relatively rich, which is obviously worried about some entry-level players, which are also relatively excellent in the same level. However, there is still a certain gap between the details and those of high-end players or machines, mainly because some of them are too bold and unrestrained and not calm and delicate. In terms of sound field, X5iii has a moderate sense of scale and oval shape, with good resolution and hierarchy, and the space filling is relatively full and surrounded.

Feiao has been controversial in terms of tuning. Some fans think that Feiao's excessive emphasis on neutral sound will appear to be insufficient HiFi. This time, the sound tone of X5iii has been appropriately warm and polished on the basis of maintaining neutrality. The overall listening feeling is relatively relaxed, with a relatively bright line feeling, and a certain charm but very light. The sound belongs to the young and energetic type. I dare not say that everyone can like this style, but it is absolutely possible that most people do not dislike it.

[High Frequency]]X5iii is more elegant and restrained, and there is no stimulus that AK4490 should have. This can be clearly felt by PO port compared with LO port. Although it is not the crystal clear style, it will not appear dark. For some normal details can still be well expressed, but the slow transient speed weakens the performance of some high-frequency extension and overtones, thus obtaining a better sense of hearing.

[intermediate frequency]]is deliberately strengthened. Compared with the high and low frequency bands, it will be slightly prominent and the hearing will be brighter. In particular, the outline of the human voice is very clear by comparison. The thickness of the human voice is moderate but it will float up a little. At the same time, there are also a little dental sounds coming out. On the whole, it is a little more exciting to grasp the ears. Relatively speaking, the elegant female voice performs better, while the male voice appears to be younger.

[Low frequency]]low frequency affects the mood and atmosphere of music. The fluffy low frequency of X5iii is my favorite type. The quantity is moderate, the speed is slightly faster, the elasticity is full, and it has a good texture. Of course, X5iii also has many problems with insufficient thrust and control of portable players, and lacks some strength and momentum under the big dynamic. Using the Feiao A5 portable earpiece in hand with X5iii together will make up for some lack of thrust, can more fully stimulate the potential of X5iii, and the overall performance will be significantly improved by one level. In particular, the medium and low frequencies are pushed more stretched and polished more moist.

X5iii sound style is still relatively loose for the matching of headphones. As long as some products with cold sound and bright tone are avoided, they will have a good matching effect, which is relatively more suitable for the interpretation of human voice and small and medium-sized music types. It is more comfortable to push down earplugs with low gain. If you push down some earplugs with high gain, you will be a little frizzy. If you push down some earplugs with high gain, it is more suitable to push some low resistance portable earphones. If you adjust the volume of Philips X2 to less than 1/3 of the total volume in your hand, you will already have a very large volume, which can bring out about 70% of the capability of headphones.

earplugs, I tried GR07, 1more double unit flat head and SE535 with good results. The cold in ear3 is somewhat unsatisfactory and somewhat too bony. What surprised me was that DN2000 was a little less than ideal, and there would be some problems of disconnection between moving iron and moving coil. Moving iron was rather frizzy, and moving coil was still somewhat underpushed. DN2000 was tamed with the help of A5 earphones. It is suggested that friends with higher voice requirements can add an A5, which is a good combination with X5iii.

Feiao X5iii is a very attractive product. On the premise of ensuring a reasonable price, it has many fun and practical functions piled up at one time, which will catch many friends and competitors off guard. On the sound quality X5iii has been greatly improved in terms of charm, and may not be the first in the same price products, but its intelligent system and richer functions have obvious advantages in practicality and playability. X5iii is more like a portable music center, with strong connection and adaptation capabilities, which will become a development vane of the mid-range national brick in the future. X5iii is very suitable as an advanced choice for the next step of initial burning, and it is also very suitable for burning friends who have urgent needs for function and scalability.
