thousand-dollar full-function bucket machine Feiao M9 evaluation

01 thousand-yuan full-function bucket machine brand:Feiao MP3

Feiao M9 is a full-function HiFi portableplayer, it is equipped with two AK4490EN chips and independent high-performance FPGA chips (hardware solver can support ISO/DFF/DSF format of DSD64/128). And supports HWA, LDAC, aptX HD and almost all known Bluetooth transmission protocols on the market on Bluetooth.

may be a little strange to HWA, it is a new wireless audio standard released by Huawei on March 27 this year, and has surpassed Sony's LDAC standard in data transmission capability as a whole. The distortion of HWA Bluetooth transmission is as low as 0.0005%, which can be said to be the Bluetooth protocol closest to transmitting lossless audio.

Feiao M9 is equipped with deeply customized Android system, which is easy to operate and fast. The factory presets third-party APP such as NetEase Cloud, MOOV, Tidal, KKBOX, etc., which can realize streaming media playback. It comes standard with 2.5mm balance and 3.5mm single-ended dual-channel earphone output interface, and supports wire control mode. Android and IOS earphones in CTIA standard can use wire control function (iOS earphones only support playback/pause).

Feiao M9 has a battery life of up to 10 hours and a deep standby time of up to 45 days. On the whole, this player is undoubtedly the manufacturing level of many 10,000-dollar portable players on the market. The price of Feiao M9 in Jingdong's official flagship store is only1798 yuan, this is no longer a "cost-effective" thing to say.

02 Brand of Big Factory Style Reflected Everywhere:Feiao MP3

Feiao M9 uses an all-aluminum alloy body, with all keys, rollers and TF card slots supporting up to 2TB expansion on the left half-arc edge, and 3.5mm/2.5mm output interface and bidirectional Type C interface below. The design of one-sided full button makes Feiao M9 blind exercise very simple, and he is no longer afraid of freezing his hands when he goes out of the street in winter.

Feiao M9 is biased towards the connotation party. The aluminum body reflects dim luster and the golden knob is very rich in texture. I can't tell where it looks, but I think it is very durable. The overall size is 60*106*13.3mm, and the screen size is3.2 inchesIPS HD Full Pad Full View Touch Display. Generally speaking, it is a portable model with less than 2,000 yuan.playerproduct, this material and shape is definitely the top of the same price.

In addition to machines, original accessories are also extremely rich. Feiao M9 factory standard TPU clear water sleeve, high-quality data cable, tempered glass protective film and several instructions, except for headphones, the rest of the accessories are all available ~

03 This is a player brand with warm sound and rich details:Feiao MP3

the earphone used in this evaluation is Baiya Xielantu, Xielantu has a large dynamic, high sensitivity, three-frequency positive sound performance, the author thinks it is very suitable forplayercompetency assessment.

Feiao M9 + Xielantu's combination of low-key and elegant

> listening to Skyland-Mich <I was amazed when this player gave me the first ear to hear: Feiao M9 has a very high low-frequency sound density, and every drum beat sound is very powerful, with quality and texture, and its position and volume are accurate and clear. In the middle and high frequencies, Feiao M9 has a strong sense of atmosphere and space, a very wide sense of sound field, and the sound image is not limited to the brain area. It has a very high degree of reduction for near-field listening. On the ultra-high frequency extension, the ultra-high frequency output of Feiao M9 is light, thin and delicate, extending the residence time field and having a very good sense of hierarchy. Generally speaking, Feiao M9 can clearly separate the complex sound source conditions of electronic music. In addition, it has the inherent advantages of low frequency, high density, good intermediate frequency junction image, high frequency, light, thin and delicate, and is very suitable for listening to electronic music.

> Listening to Spring, Summer, Autumn and Winter-Leslie Cheung <the intermediate frequency of Feiao M9 is warm as a whole, so there is a deeper feeling of gentleness and singing in the male voice. On the overall hearing, the sound source of the human voice and the background is very clean, and the sound image of the human voice is relatively front-ended, with a strong sense of reality.

> Listening to Mingban Congmei <Feiao M9 is not exciting. The internal amplification part of many thousand-dollar mid-range portable players has shrunk seriously, causing problems such as weak voice, small density and strong sense of particles. However, although Feiao M9, which is also of medium and low price, its power amplifier part is simply forced to leapfrog. Feiao M9's listening feeling can be said to be unstoppable in products of the same price.

listening summary:

Feiao M9 is a portable player product with warm, high resolution and high sound density. In the past, our impression of portable players was always detailed but weak. However, Feiao M9 achieved higher internal integration and stronger sound quality than other products through the eight-layer and third-order HDI PCB to ensure internal stability.

is written at the end:

the problem with most portable players on the market lies in the internal amplification. Because the amplification part has very strict technical requirements for the player, the volume and power consumption of desktop power amplifiers are mostly several times or even dozens of times higher than those of ordinary portable players. Think carefully about how a player's small PCB layout and limited power battery can achieve strong thrust?

shocking is that the LPF of Feiao M9 portable player at no cost uses Ti OPA1612, and the current buffer uses Ti OPA1622 amplifier. The whole machine is equipped with two OPA1622 M9 with a balanced output of up to 77mW under a load of 300 Ω, with a battery capacity of 2350mAh. This is undoubtedly a configuration that can only be possessed in a 10,000-level portable HiFi player, while Feiao M9 is only sold for 1798. What else can I say? Buy, buy, buy, buy! ~
