Feiao M15, the wind and the moon are the same, and they are connected.

the mountains and rivers are foreign, the wind and the moon are the same as the sky, send all the same friends, and get together.

unconsciously, time has 2020, and the fifth article of the new Android player review "Minority Report" has finally arrived late. I hope this series of evaluations can continue. I wish you all good luck and good health.

2020, the flagship M15 of Feiao's new product began a tour audition in Guozhuan Bar. The author was lucky enough to be one of the audition users. But don't want a sudden epidemic suddenly changed the fate of too many people. More than a month later, this player came to the author's hands. Therefore, this article also brings some unique thinking.

HiFi circle is not big, and there are very few users who are deeply "addicted. In a large 1.5 billion country, the proportion of HIFI enthusiasts in the population can definitely be called "none in all". Therefore, in this niche circle, both manufacturers and users have been active for a relatively long time, and they are somewhat familiar. The mountains and rivers are exotic, the wind and the moon are the same day, during the epidemic, it is not easy to resume work. I hope these small and medium-sized enterprises can survive the difficult period smoothly.

from how to develop to whether to live. Overnight, it has become a fate that almost every small and medium-sized enterprise must face.this protracted epidemic has brought about earth-shaking changes in the economic order and consumption habits of the whole country and the world. This time, we will try to judge whether an enterprise or even an industry can break through the shackles of ice and snow and usher in a new life of warm spring.

flagship products are often crucial to the digital industry with a relatively single product line. After all, they reflect the R & D strength of an enterprise to a large extent. This also seems to help readers understand why Huawei and Xiaomi have been quarrelling recently. Looking back on the Meizu of that year, it received Ali's investment and released dozens of new machines a year, with annual sales exceeding 25 million units at one stroke. However, at the height of the limelight, just because the flagship SOC is too weak, it is looked down upon by the entire mobile phone market and users as a whole. In a short period of time, it has directly fallen behind from the domestic first-tier brands. Now it has even come to the brink of life and death, which makes people sigh. Coincidentally, it is precisely because of Meizu's collapse that clearing inventory devices once became a daily operation. A mobile phone SOC that did not enter Meizu's legal eyes flowed into Feiao, which eventually caused quite a stir in the HIFI player industry. Even to a large extent, Feiao has continued and consolidated its leading position in Android digital players in the past two years.

this SOC is the large and small core design of Samsung Exynos 7872,2 4, which was first launched on Meizu S6 and suffered from Waterloo, but became famous in the first world war on M11 and still shone brilliantly on M15. The main frequency of the two large cores A73 is up to 2.0GHz, the main frequency of the four small cores A53 is up to 1.6GHz, the 14nm process technology, and the Mali-G71, however, it can take into account high computing performance and ultra-low power consumption, but for HIFI players, it can completely ensure the orderly operation of multiple programs. It not only ensures that M15 can complete the instantaneous switching between multi-music player APP very smoothly, but also meets the requirements of most users for page browsing, smooth video playing and even playing some hand tours that do not require too high hardware performance while listening to songs. For an Android player, the advantages are self-evident.

this time, Asahi Huacheng's flagship DAC AK4499EQ launched its portable player in China, making M15 like a "depth bomb" causing quite a stir in the circle of senior burning friends. There is no need to publicize it. The news has long been raging. Everyone is looking forward to whether the country's first AKM4499 flagship Android player can compete with AK SP2000. It is also an extremely luxurious "stacking" work. Although the price of M15 has almost doubled compared with M11Pro, it is still only 1/3 of SP2000. At the same time, it has also caused a lot of trouble for many friends in the future, both in terms of DAC selection and pricing strategy.

sharpened a sword for several years to sharpen the fragrance of plum blossoms.

counting from the first year that X7 started Feiao Android, Feiao has been deeply involved in Android player field for many years and accumulated considerable experience by M15. From M15, no matter what angle, you can vaguely see the shadow of your own flagship players. Even, in my opinion,M15 is more like a massive carnival report performance that Feiao has accumulated over the years of technology.

Rome isn't built in a day.generations, little by little, Feiao has endowed this machine with all the experience and black technology accumulated in several generations of players, making this machine a "milestone" work of Feiao.

hardware,M15 uses Asahi Kasei's first flagship current output dual DAC AK 4499EQ and uses 128-pin HTQFP package, with both index and power consumption reaching double high. A single chip has 4 primary decoding channels, and the signal-to-noise ratio of a single AK4499EQ is as high as 140dB. No matter single-ended or balanced output, the signal-to-noise ratio is greater than 118dB under 32 ohm impedance, the output power (PO maximum 490mW/balanced maximum 800mW under 32 ohm impedance), the signal-to-noise ratio of 122dB, and the paper data is horrible. The emergence of M15 makes the domestic portable player synchronized with the desktop-level decoding chip for the first time; two Japanese NDK femtosecond crystal oscillators ensure that the clock is more accurate and stable; self-developed third-generation FPGA technology effectively reduces the computing burden of the main control, And provide a variety of audio solutions; the analog potentiometer volume adjustment knob brings excellence-like volume fine-tuning, and facilitates advanced user selection that is more sensitive to volume changes;, the M15 did not extend the THX ear placement technology, which was highly praised before, but under the escort of ten low-noise op amps, it greatly increased the power while still ensuring its bottom noise control level in front of the M11PRO. On the basis of 7490mAh battery, it provides a multi-channel power supply system with 21W fast charging, compatible with QC2.0 and MTK PE double fast charging technology ensures that the machine can be filled up quickly in a relatively short time. The audio circuit uses 4 high molecular tantalum capacitors, 4 Panasonic stepless film capacitors and 8 small film capacitors. The power supply part uses 28 220uF polymer capacitors and 5 100uF high voltage capacitors. The low-pass filter circuit part adopts 4 independent designs, sharing 8 Panasonic metallized film capacitors. The PCB board with 8-layer gold sinking process is expensive, but it effectively improves the space utilization rate of PCB. Both the analog circuit and the digital circuit have a shielding cover design, and the interior is coated with a wave-absorbing material coating, which has a 2.4G frequency band wave-absorbing capability, effectively avoiding mutual interference of components. In terms of heat dissipation, thermal silicone, graphene and cupronickel fins are used to conduct heat evenly to the body shell, andhas built-in "overheat protection function". When the heat of the fuselage is too high, it will automatically terminate the running program to cool down, and a corresponding dialog box will pop up to remind the user to rest properly, which is very humanized.Even in the face of 4499EQ with huge power consumption, the "great enthusiasm" of the fuselage can be personally felt during use, but the theoretical endurance still reaches 15 hours, and the measured endurance can still exceed 12 hours under balanced output, which is of great significance to heavy users.

M15 is compatible with 2.4/5G dual-frequency Wi-Fi. The Bluetooth chip adopts Qualcomm flagship Bluetooth decoding chip CSR8675, and the USB decoding adopts Xmos XUF208, which supports 768kHz/32bit and DSD512 hard decoding. Dual Hi-Res audio authentication ensures mainstream format Bluetooth decoding reception and high-definition Bluetooth transmission, making M15 the leading portable (Bluetooth) decoding player in China. The support of full audio format and MQA 8X decoding deployment provide powerful software and hardware support for high-quality streaming media music playback. ALL to DSD II technology is quite practical for users with sound quality first. 3GB storage 64GB storage and support for 2T memory expansion greatly facilitate users to download their favorite lossless music works to the greatest extent and avoid the inconvenience of frequent memory card replacement. The powerful search function of Android intelligent system is convenient for users to retrieve the target music files stored in the body and download the latest music works online at any time, which is the advantage that traditional players are difficult to reach.

, there are not many domestic manufacturers that use expensive wood as player packaging boxes. Lebi has equipped its flagship models with tens of thousands of prices. Feiao chose the North American black walnut wooden box with fine wood this time, expressing the author's sufficient respect for the positioning of the "flagship" product. Accessories are allocated as standard and optional. The standard part includes toughened film, data charging cable and other necessary accessories. The optional "interactive gift package" includes: SK-M15 official leather case, HB4 storage box, DK1 Type-C base, LA-UA1 car isolator, and LT-TC1 double Type-C USB cable. Users can receive the order free of charge. Thisinteractive "gift" collection method, which is convenient for manufacturers to know the actual shipment volume of a product in time and to revise the subsequent production plan. At the same time, it can also get relatively real user experience feedback, which is of great importance and can also achieve the diffusion purpose of "showing up and advertising.

Feiao M15 has a weight of about 310g, a 5.15-inch 18:9 resolution 1440 × 720 pixel full-fit capacitive screen on the front and a near-full screen design. It is made of 2.5D Corning glass and has an oleophobic layer. The frame of the fuselage is made of aluminum-magnesium alloy integrated casting CNC multi-sided cutting, and the back plate is designed with carbon fiber grain grid curved glass embedded. The shape of the whole machine is the fifth generation cylindrical design of Feiao.

knob design comes from the well-received earphones of his own.E12andK3, top 3.5mm single-ended, 2.5mm balance and 4.4mm balance ports are all available., the ring mouth is wrapped in a classic golden ring, with 4.1 lines arranged in sequence. It not only highlights the beauty of the HIFI player, but also has some layers of texture than the slightly bland top design of the M11 series. Although the volume knob of M15 pays tribute to the traditional analog potentiometer adjustment method, it is still different in the author's opinion.knob is excellent, but it abandons the common sense of gear paragraph, and implements the concept of "fine adjustment" incisively and vividly., Youlan's breathing light can provide custom settings to deal with different scenes according to the fluctuation of music rhythm, and users can turn off the breathing light according to their personal preference.

has a two-way Type-C interface and a hidden self-locking TF Cato, which supports a maximum of 2TB expansion. In order to show the beauty of symmetry, the inscription of dual ak4499 is engraved on the other side. Probably because of accommodating the one-handed operation habit of most "right example" users, the physical keys are concentrated on the left side of the fuselage, including the power key, the up/down song, the play key, the customizable key and the HOLD key, which is convenient to realize one-handed operations such as one-key switching of various functions.

Feiao M15 ownsAndroid mode,pure tone mode,USB decoder modeandBluetooth reception modeand other four music modes, drivingThe vehicle mode is also supported.. In response to different usage scenarios, wireless functions such as FiiO Link, DLNA, AirPlay and WiFi are all available and comprehensive.

There is no doubt that M15 is the most successful player in the history of Feiao products.at least, I believe no one will take Feiao's "tuning" as the "starting line-up" for complaints this time.

for a long time, the tuning style of Feiao player has always been known for being calm and objective. Pay attention to the high reduction of quality, but less sound dye and simulated taste. Therefore, people who like it are very supportive, and people who don't like it are also very popular. Until the appearance of M9, Feiao's tuning style began to have many different things. Although due to its positioning, M9 is still a consumer-grade product with better listening sense than quality, the author still likes this inclusive tuning style very much. In the following generations of products, we can clearly feel that Feiao is trying to change himself in order to get more recognition and favor from users.

the appearance of M15, Feiao finally launched a"stacking"and"tuning"The" True Flagship Series "that goes hand in hand". Can't help but sigh, if not the impact of the epidemic, the player's sales are likely to be the fastest speed to refresh the previous domestic HIFI flagship sales ceiling, even if the player's price 8998 RMB, in the Feiao pricing has been considered "unprecedented".

M15 is the flagship, but it is prouddid not act recklesslythe player'svolumedo whatever you want.on the premise of ensuring both sound quality, high-power output and long endurance, the volume of this player is only 134*75*18mm. Among the flagship portable players currently in mass production,is relatively slender and small, the endurance and thrust are almost the longest, and the fluency of the system is second to none. No matter in terms of hardware, software, sound quality, quality control, periphery, interaction, appearance, endurance, function, expansion and many other aspects, it is worthy of the title of "flagship bucket machine.

, as the first large factory in China that has been deeply involved in the field of consumer-grade HIFI players for many years, Feiao has a better understanding of the needs and trends of domestic consumers. Strong research and development strength and assembly line production process make products have strong control ability from design to production to peripheral manufacturing (there are already perfect parts suppliers) and even sales links. Strong brand appeal, perfect marketing and after-sales team, a large number of distributors, large-scale and highly sticky brand fans all add a lot of confidence to the positioning and pre-sale volume of this flagship product, and also bring more bargaining power and better hardware cost sharing to manufacturers. The greater the yield, the higher the yield, the lower the cost, and the better the word-of-mouth fermentation. Under such a virtuous circle, there is no doubt that we can win more opportunities and chances in the competition.

, although for a long time in the past, Feiao's focus was more on consumer-grade HIFI products, attracting more music lovers who pursue functionality than professionalism with high-quality and inexpensive products. After years of hard work, it not only occupies a large market share, but also has accumulated strong research and development strength in software systems, wires, Bluetooth decoding and playback, earphones and other fields, and has obtained big data on user preferences and needs. It has been sent first and even grabbed the market share of many traditional earphone and wire manufacturers. Of course, the biggest benefit is the accumulation of considerable experience and strong product integration in the HIFI field.was frozen for three feet, not in a day. The birth of M15 is by no means overnight. It contains the painstaking efforts accumulated by more than a dozen products of Feiao. The more important significance is that Feiao also occupies a leading position in the field of high-end HIFI players.

, based on the current Android N self-developed operating system theory, Feiao took the lead in introducing LDAC wireless protocol, which was not gradually formed until Android was 8.0 in the Android 7 system era. At the same time, Feiao drastically increased or decreased the operating system, which was summed up little by little after a long period of failure. Each version changed more than hundreds of times, finally forming Feiao's unique software ecological environment. "Concise but never crude, stable and smooth",is different from many Android player manufacturers. Feiao's OS is full of its own understanding and secondary development of Android system. It took Feiao more than 5 years from the first glimpse of the door to the scale.we often say that opportunities are reserved for those who are prepared, precisely because Feiao has sufficient scale and keen observation, and of course sufficient cash flow. Only in this way can we boldly, visionary and sincerely introduce the rare Exynos 7872 from Meizu and build a brand-new hardware platform around it. Finally, we can find another way to take the lead in the common dilemma of domestic player SOC. In addition, Feiao has always been in the forefront of domestic manufacturers in the research on Bluetooth decoding and playback. With a keen sense of smell, Feiao has pioneered the miniaturization of Bluetooth decoding and playback products and achieved a leading position in the industry, including years of research on Feiao LINK and other wireless function APP, and finally enabled M15's Bluetooth decoding capability and network playback, in terms of connection stability to sound control, it is ahead of the flagship products of many friends.

is well-deserved to receive countless rewards in a neighboring country separated by a strip of water.

Enduranceis the first difficulty that almost every portable player has to face.Perhaps this appeal may not be urgent for most light users. However, for the medical industry in which the author is engaged, it is very precious. This year's Spring Festival is really not very ordinary, because of the epidemic, the people of the whole country have no choice but to stay at home. However, as doctors, we still have to go to work and be on duty on time. One stay on duty is more than 24 hours. During the long night, the sweat under the simple protective clothing had already soaked the underwear, and the only consolation seemed to be music. We can't put desktop decoding in the work station like most white-collar workers in the office. We can even listen to the closed big ears and immerse ourselves in it when we work. For those of us who travel all day in wards, outpatient clinics and even examination departments, an Android portable player that can connect to wireless hot spots, obtain audio network information, give priority to sound quality and have strong mobility is often more suitable for our needs. Irregular work and rest, even the meal is extravagant, more difficult to have time to charge the player. Therefore, we have more obsession with the portability and endurance of the player. Year after year, the author has been listening to streaming media such as Himalayas and shrimp music to drive away drowsiness in a difficult long night. This is why the author has long been more fond of recommending portable smart players with small size and powerful network playback capabilities. Therefore,M15 's long endurance, stable network connection and excellent sound quality have undoubtedly won the author's more favor.

May you pick more, this thing is the most lovesickness

M15 can basically be expressed as "unexpected.

In fact, users who are familiar with Feiao products may experience it,After the conversion of Feiao decoding chip from ESS to AKM, the style is no longer the kind of big opening and closing of the big river. Although it still takes the attitude of clear outline and objective calmness, it is already a bit more tender and water-like character.when we evaluate the positioning of a player and compare the popular works with small compilations, the difference between high and low is not very obvious. therefore, we often evaluate that an entry-level player can also be "comfortable" when playing small compilations ". But once you encounter a large-scale work with a huge amount of information, the difference in this "potential" or "realm" is obviously clear, and the judgment is established.The author tries to introduce"pixel"point of view, such as the difference between 3 million pixels, 20 million pixels and 0.1 billion pixel photos,has been optimized and the chips with different positioning may generally maintain a similar style in flavor after integration, the gap between the rich amount of information and the exquisite and vivid scenes is actually quite huge.we often use HIFI products"quality"and"sense of hearing.tuning is "rhyme", but the quality is "bone", without comparison,for the relatively clever medium and low-end products, we also feel that this product expresses its favorite style and is out of shape, can accept its advantages and automatically ignore its "pixel missing" defect., but for a flagship product, under the premise that the style is adjusted to meet the tastes of most people, its "high-resolution" huge amount of information can undoubtedly "realize" more details in the listener's mind. Just like when we read literary works, we can "construct" vivid 3D scenes: the more information, the better the sense of picture or presence, the restored "scene" will be closer to the original appearance of the work itself.

M15 is such a flagship work, with amazing resolution and excellent restoration. The sound field is wide, giving people a sense of sudden openness, the tone is warm, but not deliberately adding too much dyeing, but the atmosphere is not excessive smearing. It gives people a kind of freshness and beauty with a little powder, less "greasy" and "vulgar" with a little heavy makeup ".

high-frequency transparent and bright, broad and thick, excellent reduction, high-frequency gorgeous but not sharp, high-pitched but not rough; The intermediate frequency is quite brilliant in both instrumental music and vocal interpretation. In my opinion, the performance of human voice has always been the strength of AKM series chips. The human voice is relatively protruding, delicate and natural, the male voice is full of emotion, the female voice is lingering and layered. The low frequency is thick and solid, the bass drum point has achieved an amazing control from both the dive and the rebound. The connection of the three products is smooth, natural and very individual, which is a huge improvement over the previous one. In particular, the low-frequency expressiveness is more brilliant, making people shine in front of their ears.

big ear modeis that the high resistance and low sensitivity earplugs that are difficult to control by the portable player can be pushed directly to a relatively "perfect" level without the blessing of the earphone. Under the comparison of relative restraint, the earphone part of itself has reached the point of failure compared with some professional portable earphones. Of course, for some of the flagship high resistance ears that can not be completely controlled when they come to power, objectively speaking, they should be regarded rationally.

About the identity conversion of M15 as a decoder.as we all know, Feiao was first known for its earpiece products in the portable field. As for AK4499 as a portable decoding device for DAC, there are no similar competitors in China at present, and even 4497 as a portable decoding device for DAC is rarely heard of. Therefore, for a long time to come, due to the consideration of cost and shipment volume, I am afraid few manufacturers are willing to spend time and experience designing and making portable decoding devices with the same decoding hardware. If this function is deliberately considered separately for cost sharing, users may feel that the cost performance of this product will reach a higher level.

., in the M11 era, the author is relatively insensitive to this relatively "chicken rib" function. After all, in contrast, the difference in hearing is not significant. On the contrary, it slows down the processing speed of the machine and only increases the power consumption. I think it is of little significance. However, on M15, we can easily distinguish the differences in sound characteristics before and after the conversion of the same work. As for whether the control of the second generation power consumption has decreased, it is not easy to quantify, so there is no comparison.

talk about wireless webcasting and expansion functions.Feiao's wireless webcasting functions include Bluetooth decoding and playback functions. It has always been in the forefront in China in terms of hardware and software. The connection stability and low latency of related software have achieved the leading position. I will not repeat it this time.

In addition, Feiao is also a good learning enterprise,, a relatively fresh product of MQA, has also achieved "people do not have me, people have my essence".did not start early, he was good at overtaking in corners. MQA 8X's ability to expand brought more flowers and applause to Feiao from paper data alone. There are many such examples on M15. For a "diligent" manufacturer that has thought of everything in advance and produced all the surrounding matters such as toughened film, adapter wire, leather case, etc., an independent "HiFi ecology" has gradually formed to be self-sufficient, and the operation level fully considers the rights and interests of both consumers and agents. Even an enterprise that promises to never reduce the price of flagship models in order to protect the reasonable profits of merchants and relieve consumers' worries about the value preservation rate of flagship products seems.

can be seen from the leopard. M15 is undoubtedly a satisfactory answer presented by Feiao at the end of 2019.

Music APP, all in control

Bluetooth transmission, so that the distance is no longer estranged.

authoritative certification, feel free to taste

MQA8X, incisively and vividly

100 | degree network disk, play online

limited to the anxiety that was difficult to control during the epidemic, this article dragged on for nearly a month. At the beginning of the pen, the surrounding was still gloomy. Fortunately, the situation has suddenly opened up recently. As people regain their "freedom" and the industry returns to the market, I believe that people who feel that they will cherish the preciousness of life more. At the same time, they can also deeply realize that there is a persistence in hobbies in adversity, which is important for the removal of loneliness and firmness. Confidence is undoubtedly of great benefit.

pray for the common wish of taking off the shackles of masks, eager to breathe the clearest and unstained air, and listen to the most beautiful music in the world. It turns out that all this is the ordinary happiness we strive.because there are countless imagesHan Hongsuch ordinary good people, singing inside and outside, practice the great love of the world, unite as one, dispel the darkness before dawn, and let people regain the beauty of life in the disaster.perhaps, after the outbreak, for the player industry, will also welcome a rare good. At least, in my opinion,after this disaster, the people who survived the disaster, no matter how much it costs, since they have the opportunity to continue to taste the colorful life, it is worth cherishing anyway.

is ordinary and has you, but love is boundless.

the mountains and rivers are foreign, the wind and the moon are the same as the sky, send all the same friends, and get together. No matter all over the world, love and hope are always the most beautiful melody in the world, which is worth singing forever......
