1: Preamble

In today's portable Hi Fi market, there are more and more portable players with a price of more than 10000 yuan. Under the influence, everyone seems to think that if the top portable players are cheap, their voice will certainly be no better. It seems that it has become an orthodox inertia to judge the voice by price. In order to not lose, manufacturers have launched their own "top" flagship players, At this time, Feiao went in the opposite direction, taking a high cost performance ratio, just like Xiaomi in the Hi Fi world, with high configuration and low price. High cost performance is good, but can the quality of Feiao player be satisfactory? This time, let's experience it through its flagship Feiao X7:

2: Appearance

In terms of appearance, the Feiao X7 is American style. The overall design line is rough and smart. It adopts an all metal body design. The frame adopts a highlight chamfer treatment. The back of the body adopts an interesting two-level step transition design, which can make the body more suitable for palm holding and maximize the space inside the machine, The seemingly simple appearance also implies ingenuity (in the above figure, X5III is on the left, and X7+AM3 is on the right).

A 3.97-inch capacitive touch display screen is used on the front of the fuselage. What's more interesting is that it has a similar suspension design, with a resolution of 800 * 480, which can ensure the image fineness. Many friends may ask why the X7 jaw is so big? That's because Feiao X7 adopts a modular design, with its chin and independent ear amplifier. Users can change the module to meet their different listening styles. Playability is very high.

The left and right sides of the Feiao X7 are symmetrically designed. By default, the left side of the fuselage is the volume key and power key, and the right side is the previous/next song and play/pause key. In addition, users can also swap the left and right buttons according to their own usage habits, which is very user-friendly. There is a TF card expansion port on the left side of the X7 body, which supports up to 128GB TF card expansion.

A coaxial/linear output integrated output port is equipped on the top of the fuselage of the Flying Ao X7. When the X7 is used as a turntable, it can be connected to the decoding equipment through the coaxial port or connected to the ear amplifier through the linear output.

The bottom interface of the Feiao X7 will vary with different earphones. The Feiao X7 used in this evaluation is matched with the AM3 balanced earphone amplifier module. The bottom from left to right are 3.5mm headphone jack, micro usb jack and 2.5mm balanced headphone jack.

3: System Introduction

The biggest difference between Feiao X7 and traditional portable player is that it uses Android system. The system is based on Android 5.1.1. Using Android system can greatly improve the user's operating experience, and can also listen to online music by installing a third-party app, which is in line with the current user habits.

The Android interface is the same as the native Android interface. The X7 uses virtual keys at the bottom, and from left to right are the return key, home key and multi task key. Dropping down at the top can call out the shortcut bar, which is easy for users to operate. In addition, the user can also switch to pure tone mode, and the X7 will be locked in the music player interface.

The player UI design of Feiao X7 is very eye-catching, and the operation is mostly realized by sliding, and most operations can be completed by one hand. The main interface is arranged with the user's common shortcut entrance, and the setting menu can be called by sliding from left to right. Fei Ao X7 can set a variety of audio settings, such as gain, filter mode, etc. In addition, it also adds a viper sound effect to facilitate users to achieve more playing methods.

X7 classifies local music into various categories, including singers, albums, folders, etc. In addition, Feiao X7 also supports cloud playback, and users can directly listen to audio source files stored on computers or NAS through the network.

The playback interface adopts a minimalist style. The upper part can display information such as the cover, and the lower part is divided into common keys. Sliding from left to right can call out a list of songs. The operation logic is clear and natural. For a round of experience, Feiao X7 gives the author a very good feeling. First, its operation process, second, the new UI design, and third, it supports a variety of audio source formats, Some traditional players have different levels of problems in supporting ISO files, DSD files, and CUE files, but X7 takes it easy, which is really worth praising.

4: A brief comment on hearing sense

The X7 is very violent in terms of specifications. It is equipped with an ES9018s decoding chip, and the AM3 module is equipped with six OPA1622 amplifiers. The output power can reach up to 540mW under a balanced output load of 32 ohms, which is very promising.

The earplugs used in this audition are Black Oriole and OCAU+8-core silver gold-plated headphone cable. The sound source is lossless music captured from the original disc. All track auditions are based on the 2.5mm balanced mouth of the AM3 ear amplifier module.

Trial track 1: UNICORN/Hiroyuki Kono

As a rare masterpiece in recent years, UNICORN is absolutely one of the must choices for audition. First of all, what impresses the author most is the thrust of X7. The maximum volume is 120. If the volume of Black Oriole is set to about 30, it can be pushed away. Secondly, the analysis and image of X7 are both good. The instruments are well arranged and clear from each other. The sound is tight, lacking puffiness, and the middle and high frequencies are cold, Extremely high frequencies can even make people feel a bit sharp. Low frequencies are well controlled. Although the dive is not deep, it is better than the ease of retraction and release. Overall, the quality of the voice is really excellent, and the overall performance is commendable, but the voice is tight, cold, and less vigorous.

Trial track 2: It's better to be lonely/Tian Fuzhen

As Tian Fuzhen's first album, "To be" is the first classic, in which "loneliness is good" Tian Fuzhen explains her understanding of loneliness with her own voice, The X7 has a clear hierarchy of three frequencies. The mid frequency is more prominent. The human voice is close to the ear and has strong analytical power. The mouth shape can be easily perceived. The low frequency is not much, but the strength is sufficient. The voice is still cold, but it has a special flavor when used to listen to female voices.

Trial track 3: Beat it/Michael Jackson

There is no need to say more about this song. Men, women and young people should have heard about it. With excellent analysis and triple frequency control, the whole song sounds very enjoyable, and the image is clear. Especially when the guitar solo is used, the low-frequency rebound is fast, and the control of the force is quite accurate, with different degrees. The voice is still prominent and full, the density of middle and high frequencies is large, and the sense of granularity is strong. On the whole, X7 is quite suitable for this hard rock.

5: Summary

After a round of experience, the author believes that Feiao X7 is still a product worth recommending. The all metal body with a floating screen has a certain appearance. The Android system with a deeply customized player app also provides users with an excellent operating experience. In addition, the support for the audio source format is also worth praising, and the X7 is not inferior to the flagship in terms of specifications, It can be used with different earphone modules. The only disadvantage is that the tuning is a bit cold and dry. Fortunately, the earphone can be replaced. I believe it is not a problem to find your own taste. If you want to find a portable player that performs well both in sound and operation experience, the Feiao X7 is worth a try.
