"omnipotent" feel? Take you to explore the all-round way of flying pride M9.

domestic music player, also known as "national brick", has always received very high attention in HIFI circle. Especially in recent years, various manufacturers have continuously introduced more excellent products. In addition to the proud sound quality performance, there have been obvious progress in both workmanship and operation experience. Speaking of the national brick brand, Feiao has always been famous. Whether it is the early classic X3,X5, or the subsequent Android player X7, it has caused a lot of waves in the market.

this year, Feiao launched the new M-series first-generation product M7, which can be regarded as a new starting point for Feiao. With its excellent workmanship at the entry price, M7 is the first one to support LDAC Bluetooth protocol and good sound performance, which has won the recognition of many entry-level fans. Feiao also immediately followed M7's reputation and quickly launched -- FIIO M9 (hereinafter referred to as M9), a mid-range player that only sells 1798 yuan. People are very looking forward to what surprises Feiao will bring us.

appearance: family-style inheritance, but not forgetting innovation

M9 is similar to that of M7, and it is a simple style. Pure white square box, the front of the package is the front outline of M9 and some highlights of the product.

accessories also include a clear water sleeve and a coaxial adapter line.

After getting the M9 machine, it can be found that although the M9 is wider, it is shorter in height than the M7, and the thickness is basically the same, so there is not much difference in volume between the two. This reflects that the M9 fuselage is still a very portable category, and it can be easily put in your pocket when you go out. The front of both machines is equipped with a 3.2-inch IPS HD display screen with 800*480 resolution produced by LG. The display effect belongs to the first echelon in the player. For the "album cover party", you can enjoy various HD covers on this screen.

, in the details of the exterior design, we can find that M9 not only inherits some characteristics of M7, but also is more humanized. For example, with this side-type volume wheel adjustment, it can be found from the picture that the M9 wheel is no longer a smooth surface like M7, but a smoother treatment. Coupled with the increase in the area of the "groove", you will find that the M9 will adjust the volume more comfortable and secure in actual use. Although the volume key of M9 has changed from the circular design of M7 to the flat design style, the keys feel very good and there is no looseness.

M9 inherits the M7's tough straight design on the fuselage, but ingeniously uses a new "semicircular" design on the left. This design makes the original hale and hearty body of the M9 look a lot rounder, and all the operation buttons of the M9 are integrated on the left side, making the hand feel very good when holding the right hand. However, this time the M9 did not use the M7 Feiao family-style red circle blue dot power button, which is a pity. Personally, I like Feiao's power button design very much.

lacks the family-style power key design, Feiao has played "faith lamp" on M9 ". When playing music, the Feiao LOGO at the bottom of the screen will be lit, and the more interesting place is yet to come. LOGO will change different colors according to the format of the audio file you play, for example, it is blue when playing MP3 format; When playing FLAC format, it is purple. Playing HI-res levels of lossless music turns into fluorescent green. Personally, I like such design elements very much. I hope Feiao can continue this design to future products.

on the whole, M9 continues Feiao's excellent workmanship design in the field of national bricks, but I look forward to the improvement of sound quality on the basis of M7.

Voice: The extra few hundred yuan has greatly changed the sound quality.

player has always been the focus of attention and discussion. As a mid-range player, M9 will pay more attention to hardware than M7. DAC adopts a very mature dual AK4490EN scheme. Low pass filter (LPF) and audio amplifier (BUF) use a combination of one OPA1612 and two OPA1622, and support DSD128 hard decoding function. The hardware of M9 can be said to be very kind in the 2000 price, but the chip cannot directly determine the quality of the sound, so it still needs to be auditioned.

in the audition session, it is natural to take out their own M7 as a reference object. First of all, in the bottom noise control of the player, both M9 and M7 have achieved a very good level, and basically can't hear any bottom noise. Secondly, M9 will be more balanced and solid in terms of three-frequency performance. M9 will be looser and softer than M7 in terms of low frequency, and the texture of low frequency will be better. The improvement in the mid-frequency human voice is the most obvious. When listening to the M9, it is obvious that the original mania on the M7 has basically disappeared, and the human voice has become clearer and smoother. The vocal position is no longer as close to the ears of M7, but in a very moderate position. The improvement of high frequency performance is not as obvious as that of medium frequency, but fortunately, the brightness is moderate, which is a non-stimulating and comfortable style, and can be easily controlled by popular styles that most people like. Finally, the performance of the lower sound field, the M9 is wider than the M7 sound field, the three-dimensional effect is stronger, and the layers between the instrument and the voice are clear. To sum up, although M9 is only a few hundred yuan more expensive than M7, the sound performance can be said to be a qualitative leap, even compared with any player within the 2000 price.

Hardware: The Well-deserved "Bucket Machine" in the Player"

national brick has always had excellent voice, but the operation experience is not humanized enough. However, after using the machine for a period of time, it completely changed my view. M9 can be said to be the well-deserved "bucket machine" in the current player ".

, M9 uses the same Samsung Exynos 7270 processor as M7, which is also the first Samsung processor in the player. The 14nm process is matched with two A53 architecture cores, which are excellent in both performance and power consumption. With Feiao's own deeply customized system, both song cutting and sliding operations are very smooth in actual use, without any Caton.

worth mentioning that M9 is also pre-installed with third-party music apps such as NetEase Cloud, KKBOX and MOOV, which is a big surprise for users who like to listen to songs online at ordinary times.

have to say is that it supports full-format Bluetooth encoding protocol. M9 uses the 4.2 Bluetooth version, which is fully supported by Qualcomm's aptx hd and aptx protocols, Sony's LDAC protocol, and even Huawei's HWA protocol, which was recently released. For the endless wireless Bluetooth devices in the future, I believe M9 will become the best Bluetooth device partner. In addition to supporting full-format Bluetooth encoding, M9 also supports asynchronous USB DAC and USB Audio digital output and other functions. I believe there is no doubt about the playability.

endurance performance, there is no need to worry about frequent charging of the machine for 10 hours and 45 days of deep standby.

summary

M9 may not be the best player for music enthusiasts, but it is definitely the most suitable choice for most music lovers. Excellent sound quality performance, smooth operating system, adaptation to all the audio Bluetooth protocols on the market and various powerful functions, as long as you can think of M9. M9 should be the best choice at present for a player that can be used at ease and has outstanding comprehensive performance at the 2000 price.
