gives you a brand-new music world -- Fiio Feiao X7 Mark II portable HD lossless music player

With the continuous development of digital technology, it is more and more widely used to listen to online music files, browse web pages and photography, and even receive terrestrial satellite signals to watch satellite TV programs. In addition to the basic functions of multimedia playback, wireless Bluetooth transmission, NFC and other connection functions are added to the display screen, so as to facilitate players with fever to connect to external Bluetooth audio equipment.

Feiao, a brand that independently develops and produces various portable audio products such as lossless music players, launched a flagship "Android intelligent master-level lossless music player" in 2015. The pursuit of neutral sound and the restoration of natural and real tuning style are one of the major features of Feiao X series audio players, which can not only restore the most original sound effects of sound, but also can facilitate users to choose headphones or earphone products according to their listening needs. Two years later, Feiao launched a new flagship music player -- X7 Mark II in 2017. The new generation of X7 Mark II has made a major upgrade on the basis of the original first generation X7, thus making fever players feel completely new from the inside out. X7 Mark II, as a brand-new intelligent high-definition lossless music player, adopts two working modes of Android and pure tone. Android system uses Android 5.1 version system deeply customized by Feiao software team. After optimization of the underlying design, it can install third-party applications according to different needs of individuals, or users can freely choose whether to uninstall APP under Google service framework, so as to release more available space. In pure tone mode, there is no interference from other applications, thus making sound playback purer and running smoother. The new UI interface is customized and optimized by Feiao design team, supporting the switching function of three themes at any time.

's internal manufacturing process adopts ES9028 series high-end chip ES9028 PRO produced by ESS Technology Company. It has 8 independent audio lines with a signal-to-noise ratio of 129dB and a total harmonic distortion plus noise of-120dB. At the same time, non-ASRC, I .e. asynchronous sampling rate conversion, is adopted to effectively improve the hearing feeling. The main control chip is the world's first quad-core chip RK3188. X7 Mark II adopts ES9028PRO-specific filter and distortion compensation algorithm technology. Special sound processing increases the second harmonic component to ensure that the sweetness and charm of the sound can be highlighted when the sound is played back. In order to improve the accuracy and stability of the clock, three independent active crystal oscillators are used, which are responsible for DSD and 44.4kHZ sequence, 48kHz sequence and 384kHz sequence respectively. The jitter is reduced by matching synchronization, which is more conducive to sound reduction. In addition, X7 Mark II comes standard with balanced and single-ended dual-channel earphone output, adopts AM3A earphone module, uses JFET precision dual-channel operational amplifier AD8620 as the front operational amplifier of the earphone module, and is matched with OPA926, a fever earphone chip customized for X7 Mark II. The earphone module part provides a replaceable design for fever players, bringing rich entertainment experience. The PCB circuit board uses 7 shielding covers, and the main control part and the operational amplifier part adopt double-layer shielding measures, which effectively improves the reliability and anti-interference ability, and guarantees stable sound performance. The body has built-in 2G memory and 64G storage space, which can easily run multiple APP, making the overall performance operation smoother.

X7 Mark II body is a titanium CNC aluminum alloy shell, equipped with a 3.97-inch IPS TFT touch display. The left side bar of the fuselage is equipped with a roller type 45 ℃ string volume knob, a play/pause button and an item selection button. The right column has a dual memory card expansion card slot, which can put two 256GB MicroSD cards at the same time. There is a line/coaxial/fiber 3.5mm output interface and power button at the top position, and a Micro USB data interface and a balanced, single-ended earphone output interface at the bottom position. At the same time, X7 Mark II has carried out technical optimization for WiFi signal, Bluetooth transmission, 2.4G signal and mobile phone signal interference, and improved the anti-interference performance of the product. Bluetooth transmission adopts a new 4.1 version and Bluetooth Apt-X technology, which can realize Bluetooth dual-mode signal transmission. It can also receive Bluetooth signals while transmitting Bluetooth signals, and supports dual-frequency WiFi signal connection, so that players with fever have a better music experience and can also feel faster and more stable speed improvement.

X7 Mark II, as a new generation music player, has made great changes in all aspects compared with X7 first generation music player, so what are the improvements in sound performance? Through the use of different styles of music for audition, all music files used in the audition process are in FLAC lossless format. First of all, I listened to a small-scale orchestral music. Under the sound playback of X7 Mark II, I felt balanced and very natural. The hierarchy and density of the performance between the instruments were very clear and detailed. I did not feel any turbidity and confusion, and I was also rich in a certain bright texture. Then I listened to a female voice performance, which was delicate and slightly tender, and seemed very enduring. With the extension of this delicate feeling, it was also accompanied by the balanced and natural low-frequency harmony in the background music. The high-frequency position extended just right, and the expression of human voice and music details was also quite excellent. Then jazz was used for audition. The light rhythm of the piano was very strong, the texture brought out was real and strong, the positioning performance of the instrument was equally accurate, and the sound made by the jazz drum was naturally moderate, which made the whole music more expressive. It is contagious, and there is a feeling of lingering sound around the beam.

Fiio Feiao X7 Mark II portable high-definition lossless music player has taken on a new look from the inside out, and has made comprehensive improvements in terms of appearance design, hardware configuration, software system and other aspects. At the same time, as a portable music player, it not only needs to have certain restrictions on the body design, but more importantly, it needs a powerful decoding chip. Now, Fiio Feiao X7 Mark II portable high-definition lossless music player can bring you a brand-new auditory experience.
