HiFi no longer stops at wired, Feiao M7 portable lossless music player


HiFi players have always seemed to be very far away from ordinary consumers, and they are all areas that some fever-level players will touch. However, with the improvement of mobile phone playing quality and the convenience of various music apps in recent years, many HiFi manufacturers feel more and more pressure from the market, so they have launched entry-level players in order to meet the needs of ordinary consumers.

, but the introduction of price alone cannot impress consumers, so Feiao cleverly launched the product Feiao M7 portable lossless music player for this experience. Feiao M7 is different from other entry-level players in that it actually supports aptX™HD and LDAC, two ultra-high sound quality wireless transmission protocols, have given users who have moved to the Bluetooth headset camp due to the cancellation of the 3.5mm audio port in recent years a better choice.

then let's take a look at the performance of Feiao M7 portable lossless music player.

1. packaging: protection in place, sincerity is sufficient

's design language is different from that of the past, but it has a little shadow in the details. The appearance design of the package is simple. The lower right corner of the front does not mark DSD hardware solution and various core op amp chip information like previous HiFi players. Instead, two Bluetooth HD sound quality transmission protocols LDAC and aptX are used.™HD, you can see the difference in its main aspects. From the back, it can be seen that M7 has launched as many as six colors, which is rare in HiFi players, which is also a kind of satisfaction for entry-level users.

adopts the design of inner and outer boxes, and there is also a pure white heaven and earth box packaging inside. After taking out the player, the bottom is accessories and instructions.

accessories. Apart from the instruction warranty card, there are transparent protective shells and charging lines. The protective film has been pasted on the screen before leaving the factory. This is more common in mobile phone manufacturers. HiFi manufacturers can do it kindly. After all, the special protective film for HiFi players is still relatively difficult to buy.

can also purchase PU leather covers separately.

, this leather case has done a good job in texture and fit. The radian of the corners and the edge sealing treatment of the leather edge are in place. After wearing the leather case, the texture of the whole machine has been greatly improved. It is difficult to imagine that it will be an entry-level machine.

2. Body: New Language for Simple Design

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

mentioned earlier, M7, as a brand-new series of Feiao, has adopted a new appearance design, abandoning the battery furnace appearance design that was previously used in the low-end series and is most familiar to everyone, and has been simplified from the appearance of high-end series such as X7MKII. A 3.2-inch touch screen is used on the front, and the upper part of the fuselage is specially reserved at the bottom. The design will be mentioned later.

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

The left side of the body is the main key control area. The key functions are volume scroll wheel, previous song, play pause, and next song. Different from the complicated three-dimensional cutting appearance on the side of X7MKII, the side of M7 adopts a simple frosted plane, so the whole machine looks simple and atmospheric.

is the finishing touch of the whole machine. It uses 45-degree bevel lines and gold-plated edges, which is very much like a twill gear, full of mechanical feeling.

has been designed with a depression at the scroll wheel and a three-stage layering. In addition to the full design feeling, it can prevent the volume of the scroll wheel from being accidentally touched and causing the volume to change or the scroll wheel to be damaged. When the roller rotates, the damping is moderate and there is a sense of paragraph. When it is moved, it is very similar to the feeling of manually winding a mechanical watch. The vibration of each paragraph is full of ritual feeling.

body is Feiao's iconic red circle switch button and PO/LO 2-in -1 output port. There is a prompt light in the middle of the switch button. There will be different colors of prompt lights in different states such as startup and charging, which is convenient for users to view in the lock screen state. Unfortunately, there is no balanced output port, but the balance line is not the choice of entry-level players.

body is a TF card jack, which can support 512GB expansion. At the bottom is the charging and data interface, which is more convenient to share the data cable with the mobile phone.

fuselage. This is almost the necessary certification for audio equipment introduced in recent years. It is no longer a bright spot. On the contrary, I think aptX should be printed.™HD and LDAC. There is a rectangular area at the top. This area is the only area of the whole body that is not made of aluminum alloy except the screen. I think you can guess that this is the transmission area of wireless signals. In order to make the Bluetooth transmission quality better and leave such a large antenna area for M7, the lower part of the screen should also be designed to make enough space for the wireless module.

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

Feiao M7 does not adopt too fancy design. It is simple and simple. The weight of the whole machine is only 116g. After adding the protective cover, it is also relatively light and suitable for holding. The roller position is just at the thumb position for easy operation. From the fine frosting on the integrally cut aluminum alloy body and the chamfering on the corners of the whole machine, it can be seen that Feiao has high requirements for M7 production.

3. system: deep customization, smooth operation

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

Feiao M7 does not use a simple player system like ordinary entry-level national bricks, but uses a deeply customized Android system, which brings a smooth experience with the touch screen. However, due to the Android system, the boot speed is slightly slower, which takes about 30 seconds.

Lock Screen & Desktop

system adopts sliding unlocking similar to that of mobile phone, and music playing control can also be carried out in the screen locking state. After entering the main interface, it is mainly divided into six sections. The icon is designed to be cute. Without the three navigation keys of Android system, it is replaced by the gesture operation of "the bottom of the left side of the screen slides up to return, and the bottom of the right side slides up to return to the home page". It is quick and simple to use and makes the interface more beautiful.

Feiao Music

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

Feiao Music is an original App of Feiao. The main interface is very simple. The classification and list of music commonly used by the player are listed with different icons. Click on the album picture in the playback interface to perform a series of operations such as equalizer, playback mode, playlist, etc., and may also view the detailed information of the song.

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

In the settings of the player, you can set it according to your own playing habits or usage requirements. The functions such as timing shutdown and folder hopping are more practical. The settings in the equalizer are also more detailed. If you don't know much about the equalizer settings, you can also choose from the preset nine modes.

radio

M7 is probably the first time HiFi player has been added. Although there are fewer and fewer people listening to the radio, on the other hand, the surviving radio stations have relatively high-quality content, so there are still many listeners. This makes the M7 more diverse in gameplay, and also supports the selection of broadcast areas within the settings, and you can listen to radio stations in five regions around the world.

File Manager & Gallery & Technical Support

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

Because the bottom layer is still Android, Feiao has built a file manager, gallery, etc., and also supports the search function. Photos in the gallery can also be set as desktop. In technical support, M7 can be upgraded with firmware and answers to common questions.

Settings

settings page. The Bluetooth connection settings are very detailed. LDAC also has three settings: sound quality priority, standard, and connection priority. It can be seen that Feiao M7 is a player that pays great attention to wireless connection.

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

Feiao M7 is equipped with Samsung's first mobile application processor exynos 7270 specially designed for wearable devices. It adopts dual-core A53 architecture and uses a 14nm process. The overall operation with Feiao's customized system is very smooth. This low-power AP also enables its wired endurance of up to 20 hours and wireless endurance of up to 30 hours, which has surpassed the endurance of all Bluetooth headsets on the market.

4. Wireless: Entry Price, Flagship Configuration

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

as a player, not to mention sound quality is a hooligan. But for Feiao M7, the first thing I want to say is not the traditional sound quality performance, but its powerful wireless connection. As the first to carry LDAC and aptX™Although the HiFi player with HD technology is only an entry-level in price, it is already a flagship level in terms of wireless connection configuration. Even at present, no flagship player is equipped with these two technologies, even if Sony's BRICS NW-WM1Z is only matched with its own LDAC.

, many people may not know these two technologies. Next, let's introduce aptX to you.™HD and LDAC.

aptX™HD

aptX is an encoding standard for Bluetooth audio transmission. It has larger transmission bandwidth and lower delay than traditional SBC narrowband encoding. The delay of SBC encoding is generally more than 120ms, while aptX can achieve a delay of about 40ms, and the maximum delay that the human body can feel is 70ms. Therefore, Bluetooth audio encoded by aptX can make users feel no delay. While aptX™HD is an improvement based on aptX coding, supporting audio up to 24 bit/48kHz, and the ratio is increased from 352 kbps of aptX to 576 kbps. Previously, aptX could only achieve CD sound quality, while aptX™HD is already higher than 16 bit, with a CD sound quality with a ratio of about 320 kbps.

LDAC

LDAC is a wireless audio coding technology developed by Sony. The traditional Bluetooth audio transmission technology compresses LPCM audio to 44.1kHz and 16 bits and then transmits it through 328 kbps. The whole process is compressed twice, resulting in a serious decline in sound quality. The LDAC transmission mode can directly transmit the audio at a quality of 96 kHz/24 bit, minimizing the quality lost during audio transmission. LDAC can ensure the amount of information transmitted by wireless audio, making the details of music richer, sound density greater, and will not appear dry and weak.

If you find it difficult to understand, look at the comparison of the bit rate data of the four encoding methods to see the advantages and disadvantages:

SBC 328 kbps

aptX 352 kbps

aptX™HD 576 kbps

LDAC 990 kbps

aptX has reached the standard of CD sound quality, and LDAC has entered the quality of Flac lossless format. It can be said that it can finally enjoy nearly lossless sound quality on wireless devices. Of course, the premise is that your headphones also support these coding protocols, and you don't have aptX in your hand.™HD and LDAC devices, but there is a Sony home XB950BT that supports aptX, then let's listen to whether there is any real difference with ordinary Bluetooth connection.

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

XB950BT this Bluetooth headset belongs to the low frequency style, there is also a BASS BOOST mode specially to enhance the low frequency, but this mode overtone is too fat, I still prefer solid low frequency, so I have never used it. In the aptX mode of M7, the texture of low frequency is well improved, which improves the dynamic difference under SBC coding and dives deeper. Although the details have been improved, there is still a certain distance from the wired connection, and aptX support should be found later.™HD and LDAC wireless headphones cannot waste such a high wireless configuration of M7.

5. sound quality: balanced ear moistening, not tired after listening for a long time

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

focuses on wireless connection, M7 has not fallen behind in terms of cable. M7 uses an ESS Combo chip 9018Q2C, which is different from the common DAC and earpiece chip. The digital and analog parts of the ES9018Q2C use independent power supply, and the analog earpiece also uses independent dual power supply to minimize the influence between each module. This audition uses Shure's SE425, Yuyin's PK1 and Feiao's FH1 respectively. The three earplugs have their own characteristics, which can just do a comprehensive audition for M7.

Shure SE425

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

SE425, as Shure's former sub-flagship headset, uses a unilateral double-acting iron unit, which has the characteristics of high cleverness and easy pushing. The voice is biased towards female voice, clear, ethereal and high resolution. The bottom noise of M7 is well controlled, and high-sensitivity headphones such as SE425 cannot hear the noise to the end, which should benefit from the reasonable design of its chip independent power supply and circuit. M7 adjusted the vocals slightly to the background, not too much, and not much modification. My own style is warm, and the sound becomes more endurant with the cold SE425. Of course, the female voice has less inspiration. However, one of the advantages of matching is that the low-frequency sense of SE425 has been improved. Previously, the low-frequency sense of SE425 was more textured and less measured. It may appear slightly insufficient when listening to pop music, and the matching with M7 just fills in this part of the defect.

Yuyin PK1

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

PK1 is just a flat-headed plug, it is notwithstanding that it is difficult to push and control. It is perfectly suitable to test the thrust of M7. PK1 under M7, although the sound field cannot be completely opened, it can already reflect the natural sense of the sound field with flat head plug, and listening to live music with large amount of information will not feel squeezed. The human voice is still the strength of M7, and the singer's voice is very solid, but I have to admit that although the good analysis makes the background information sufficient, the performance of the instrument is somewhat thin. As an entry-level HiFi player, it is unrealistic to require M7 to push PK1 completely. After all, PK1 is a master who has to be served by desktop computers.

Feiao FH1

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

, as the entry-level circle of Feiao, the handset on the FH1 line also shows its identity that the mobile phone can be plugged in directly. The impedance of only 26 ohms also determines that it is easier to push, so the test is the control. The matching style of FH1 and M7 is very similar. They are not students of partial subjects. The three frequencies are balanced and only slightly biased to the low frequency. This leads to the sound of drums in the song. Although the dive is not deep, it has reached a point. The overtone control is just right. It seems that M7 knows when to stop the instrument and can give you a soft feeling when listening to the vibrato of students.

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

, after listening to three earplugs, it was found that the thrust of M7 was not its strong point, but its strong point was in the three frequencies of analysis and balance, and the voice was slightly shifted to the low frequency. Everything seemed to be afraid of breaking the whole balance. Obviously, this sound was not used by HiFi players to pursue a needle in the sound, but a machine used to listen to songs slowly. It could accompany you for an afternoon without tiredness.

6. summary

HiFi 不再止步于有线,飞傲 M7 便携无损音乐播放器

has played many HiFi players, Feiao M7 can still enter my shopping list. The entry-level price has a wireless configuration that flagship machine does not have. There is no doubt that the future will be the era of wireless audio. At least most consumers will prefer more convenient wireless devices. And Feiao M7 took advantage of aptX™HD, LDAC and other high-definition Bluetooth protocols have not yet entered the market in time on smart phones, which is a good supplement to this vacancy. The warm and balanced tuning can be understood as having no characteristics or versatile. The listening voice is suitable for those who love the story behind music and also for those who need music company.
