"Think what you think, give you what you need" Feiao M9 brief comment

before, when I was writing the evaluation of Feiao M7, I expressed something like "Feiao is trying to improve the product experience and attaches importance to the opinions of users as always. The most important point is that Feiao has been updating portable player products calmly in this impetuous portable player market." In this way of thinking, the appearance of M9 is natural.

Feiao M9 is the same as M7, and the overall size and corrugated paper material of the inner box are the same. The accessories are as follows: a Type C interface data line and coaxial adapter line, a tempered film that has been pasted on the machine, a TUP clean water cover, warranty card and instructions.

M9 is still very proud. The anodized feel of the shell is fine, and the touch of the keys is uniform and there is no skew. The whole machine is tightly sewn. The overall size of M9 is shorter than M7, the width increases a lot, and the thickness is basically the same. Compared with M7 with large forehead, M9 has basically no groove points in its overall shape. Moreover, when the black edge under the screen is relatively large, a luminous LOGO is added as a visual fill, and this luminous LOGO can represent the code rate specification of the current music played in different colors. For example, the lossy format is blue, ordinary lossless purple, the Hi-Res standard is yellow, DSD is green, and it is red when charging or low power. Of course, you can turn it off. In addition, the M9 backplane finally did not have a signal window patch that greatly affected the integrity. Feiao opened the window at the top, and the left row from top to bottom was a switch lock screen, volume scroll wheel, playback pause, previous and next song, TF card slot. There is no key interface on the right side. At the bottom, there are 3.5mm PO LO coaxial composite interfaces, 2.5mm balanced interfaces, and gold decorative rings, with Type C data charging ports in the middle. The screen is fully fitted with the same 3.2-inch 480X800 resolution as M7.

a few months ago, boss j of feiao sent out an l-shaped PCB board without patches in the group, saying, "our player PCB board is becoming more and more like a mobile phone." At that time, a group of friends were guessing what player this was, and the result was M9. Compared with the square PCB motherboard of M7, the shape of the motherboard of M9 is L-shaped, which is very similar to that of the current mobile phone motherboard. Looking at the disassembly diagram, it shows that the utilization rate of internal space has improved a lot. After all, it is still very difficult for a player of M9 volume to put this configuration of hardware.

is different from M7, which is a highly integrated low-power architecture. M9 is equipped with two AK4490 and a traditional independent earphone architecture. The battery capacity is 2350mAh, and the 32-euro load output power is: single-ended 170mW, balanced 200mW (without boosting). The measured single-ended high-gain ordinary FLAC plays for 10 and a half hours. The wireless network and Bluetooth are closed and there is no operation. The balance port has no test endurance because there is no balanced earphone. The M9 balanced output has a boosting mode. This mode is suitable for high impedance earphones. Thanks to M9 master control or Samsung Orion 7270, dual Cortex A53 core, main frequency 1G, 14nm process, standby time is no different from M7, so there is no need to shut down at all.

M9 has all other functions except halving the endurance and no FM radio, and has multiple balance ports and coaxial ports, as well as all functions related to USB DAC and WIFI. At present, the Bluetooth function of M9 is more perfect. In addition to the existing aptX,aptX HD and LDAC, HWA(LHDC) is also added. Of course, the Bluetooth reception mode not implemented on M7 is also available on M9, which supports SBC and LDAC (to be updated) reception. With wireless WIFI, of course, there will also be WIFI song transmission function and online firmware update function. LINK function is said to be updated on IOS platform first, and now it is in the testing process. Regarding third-party online music applications, M9 had NetEase Cloud in its firmware when I wrote this evaluation. Feiao plans to build some third-party music streaming applications into M9 for users to use. Of course, these third parties can uninstall freely. (HWA and two-way Bluetooth of M7 should be updated)

the machine I have now is no different from the official version of the hardware, the sound should be the official version. The sound style of M9 is very similar to that of Feiao Q5 decoding earpiece in my hand. It is difficult to distinguish whether it is M9 or Q5 without AB. Feiao should have the intention to let M9 move closer to Q5. When two AB, the sense of Q5DAC mode is slightly more obvious than M9 line. M9 sound has a very slight sound edge and blurring effect than Q5DAC mode, the M9 high frequency is slightly blunt than the Q5DCA mode, and the violin feel position in the Q5DAC mode is farther and slimmer than the M9. The vocal positions of M9 and Q5 are basically the same, except that the vocal edge of Q5 is clean, and the vocal edge of M9 has a slight hazy feeling. The low frequency elasticity of M9 is more obvious than that of Q5, and the low frequency relative speed of Q5 is slower. There is no other difference. The big style is the same. These are all slight differences. No, AB is hard for me to hear the difference. (The bundled Q5 is softer than DAC mode. I don't particularly like it. DAC mode is very good.)

If M9 and M7 are compared with AB, the tuning of the two machines is very pleasing to the popular voice. The overall sound information of M9 is higher than that of M7. At the same time, the sound of M7 is slightly dry compared with M9. The high frequency brightness difference between M7 and M9 is very small. The high frequency edge of M9 has some extended overtones, and M7 is relatively dry with no overtones. The human voice is the smallest difference. I can't hear the difference in position. It is relatively close. The human voice knot of M7 is slightly larger than that of M9. It also has the tendency of high frequency to be dry. The human voice of M9 is more moist. The sound field is the biggest difference between the two. The sound field of M9 is one circle larger. The feeling of listening to shading and dusk is that M9 sound comes from all directions with a sense of scale and hierarchy. M7 is concentrated in the back of the head and is relatively flat. There is no difference in the amount of low frequency, and there is no problem of procrastination and rebound too slowly. The advantage of low frequency of M9 is to dive better, and the feeling of M7 is that it cannot go down until the point is reached.

says "I think what you think and give you what you need". This is my evaluation of the M9. When the M7 was released, some users were a little dissatisfied because of some lack of functions and appearance. These requirements are obvious to Feiao. This time, the new M9 has indeed strengthened a lot in function. For example, balance port and coaxial output function, wireless WIFI and two-way Bluetooth, compatibility and LINK function of third-party music application tested. There is no slot in the appearance this time. The key is that the price has not been 2000. In the market atmosphere where brick prices take off in this country, the price is as close to the people as ever. As for finding a father party, it is better to respect yourself (￣ ￣ ￣ ￣).

So Feiao brought a very competitive product to the national brick market, "think what you think and give what you need" this is M9.
