the all-round responsibility at the price of 2000 yuan, this feiao earmuff has the characteristic of "taking everything" in all aspects.

actually saw them launch flagship portable decoding earpiece Q5 at a press conference in Feiao quite early. However, with the continuous development of new products on portable music players and earphones, Q5 has been somewhat forgotten in my mind. I didn't expect that at the beginning of the new year, the prototype of Q5 came to the MC evaluation room without a word. What kind of performance can this flagship earring, which has been polished by Feiao for two years, finally bring? I am as curious as readers.

, as Feiao's flagship decoding earpiece, Q5, like the X7 series with flagship positioning in the same door portable player, adopts the design of replaceable earpiece module and is also common with the latter's earpiece module. This is undoubtedly the most playable and one of the biggest highlights on Q5. The standard earphone module of Q5 is the same as the X7 Mark II I have tested before. It is an AM3A module with balanced + single-ended dual earphone output at the same time. The module uses the high-bandwidth JFET dual-channel operational amplifier AD862 as the front-stage operational amplifier of the ear amplifier module, and the matching ear amplifier chip is OPA926, a product previously customized for X7 Mark II.

When evaluating X7 Mark II before, the high quality of AM3A module left a good impression on me, and now it has become the standard of Q5, which is really kind. I noticed that in addition to having a Micro USB interface on the earphone module, Q5 also provides a Micro USB interface on one side of the body. The former is used for data connection and the latter focuses on charging. This design is to ensure that Q5 can obtain high-quality power supply.

▲ List of interfaces on the earphone module, including 3.5mm single-ended earphone interface, 2.5mm balanced interface and Micro USB interface.

▲ There are two 3.5mm connectors on the top and silver trim rings around it. Compared with the gold trim rings that many products like to use, this design is more compatible with the overall style of the fuselage. One of the two interfaces is a coaxial/fiber/line input interface and the other is a line output interface. In addition, the high and low gain adjustment switch and bass switch are also arranged here.

▲ The Micro USB interface on the left side of the body is used for charging. The three keys near the top include a separate Bluetooth control key. In Bluetooth mode and non-Bluetooth mode, the keys will play different roles.

Bluetooth is another part worth mentioning on Q5. As more and more portable players adopt intelligent systems, and mobile devices become the main audio source of users and other application trends, the introduction of Bluetooth function makes Q5 more widely used. The Bluetooth chip it uses is Qualcomm CSR8670, which is based on Bluetooth 4.2 technology and supports aptX standard. In order to reduce the influence of DAC on sound, Q5 bypassed the Bluetooth internal DAC module during design, directly digitally output to XMOS, decoded by XMOS and then handed over to its internal professional audio DAC for processing, which can retain music information more completely and take a step higher than traditional Bluetooth audio equipment in various specifications, so as to achieve the purpose of sound performance consistent with wired input as much as possible.

In addition to Bluetooth wireless connection, Q5 is also a comprehensive product in other input modes, and supports common input modes such as optical fiber, coaxial and line. The aforementioned Micro USB interface for data connection can not only directly connect PC and notebook computer, but also connect with Apple's mobile devices such as iPad and iPhone through Lightning-to-Micro USB cable. Due to passing Apple's official MFi certification, the reliability of use is guaranteed. The above patch lines and data lines are basically standard in Q5 accessories, which also saves users the extra purchase cost and trouble.

, as such an all-round product, Feiao carries two AKM AK4490 DAC chips on Q5 to ensure its decoding effect. Each AK4490 is matched with a OPA1642 op amp, which supports a sampling rate of 384kHz/32bit and a native DSD output up to DSD256. For the input of digital audio equipment such as computers and mobile phones, Q5 uses XUF208 of XMOS USB Audio platform, which is compatible with USB 2.0 and provides more stable performance and more powerful functions.

has so many modes. Considering the interference between each other, Feiao has designed 7 LDO circuits inside Q5, so that DAC, LO, volume IC, LPF, earphone, XMOS and Bluetooth can respectively pass through independent power supply circuits to reduce their interference with each other and ensure purer sound quality performance.

▲ "Accessories Factory" Feiao will not be stingy on Q5 accessories. In addition to the commonly used USB data cable, anti-skid pad, binding belt and storage mesh bag, it also provides a wealth of wires, including Lightning-to-Micro USB short line, 3.5mm recording line, coaxial adapter line, optical fiber adapter head, and T5 screwdriver for replacing ear module.

appearance: continuation of exquisite workmanship, no lack of characteristic elements

will go back and talk about the process and design of Q5. The progress of Feiao's new products in the past year is obvious to all. Q5 has made new innovations and progress on the basis of continuing the family style. Although the shape is square and simple at first glance, it is not difficult to feel its intentions when looking closely at its materials and craftsmanship.

Q5 is not a whole plane, and a brushed metal panel is cut out in the middle part, which has a good visual effect when matched with the matte body. Its body adopts all-aluminum alloy CNC technology, supplemented by surface treatment of sand blasting and wire drawing, and feels very delicate. The arc of the fuselage looks tough, but it will not feel the hand when holding it. On the other hand, PU leather is pasted on the back of the fuselage to improve the grip feeling and effectively prevent the surface of the equipment from being scratched during binding. Personally, I prefer this design style of incorporating leather material into the metal machine body, which often brings better texture and style to the product.

▲ The large area of PU leather material on the back not only brings a delicate touch different from the metal body, but also effectively prevents possible scratches when binding equipment.

Of course, the two family designs of "Feiao Hong" and 45 string pattern are not absent from Q5. The inclined design of the sinking platform on the side gives it more design details worth tasting. The gap between multiple interfaces and the body also maintains a uniform gap, and there is no uneven gap I have seen on some players and earphones before. Generally speaking, Q5 has inherited the design style of Feiao's generation of family, but at the same time there is no lack of its own unique elements, and its overall performance has not lost to similar products of international brands.

audition: Bluetooth is convenient and of outstanding quality.

I first experienced the Bluetooth function of Q5. Press the "PAIR" key for a long time after starting up, Q5 will enter the Bluetooth pairing state. Although it has no screen, we can know the current state at a glance through the blue indicator light flashing on the front of its body. At the same time, through the earphone connected to Q5, the pairing between Q5 and the device can also be grasped through its voice prompt. I use a mobile phone that also supports aptX to connect with Q5 wirelessly via Bluetooth, and the headset I tried to listen to is Feiao F9 PRO.

Compared with the sound performance when F9 PRO is directly connected to the mobile phone to listen to music, the sound after one "transit" through Q5 has an audible improvement. Especially in the details, fullness and sound field scale of the sound, the feeling changes obviously. Q5 can naturally give full play to the energy of F9 PRO compared with mobile phones. At the same time, both sides support aptX to ensure that the sound quality of most music will not be lost during wireless transmission. Of course, higher-level sound sources should be counted separately.

is bundled with mobile phones, Q5 with larger volume has a better bundling experience than Q1 Mark II I have experienced before. For example, on the 5.5-inch mobile phone I use, Q1 Mark II will be a little smaller when bundled, while Q5 is closer to the size of the mobile phone, so the bundled effect is naturally better. Of course, if it is bundled with a portable player, the effect will be more harmonious. Since Q5 supports that it can be connected to Apple mobile devices, I also deliberately connected to the iPad mini2 through the Lightning-to-Micro USB cable in the attachment during the audition, and conducted the audition. At the same time, I also connected Q5 to the computer to experience its sound performance under the USB DAC function. In terms of earphones, Feiao F9 PRO, AKG N5005 and Sennheiser HD 600 were selected to match Q5.

is matched with the iPad mini 2, the most obvious feeling is that Q5 gives me a more three-dimensional sense of listening and releases a wider sound field. The iPad mini 2 does not have strong bass when matched with headphones alone. With the addition of Q5, it has achieved a more extended dive. The sense of quantity is obviously increased, and the elasticity and strength are also significantly enhanced. The pause when listening to cello and bass drum is quite obvious.

in the intermediate frequency part, which originally performed well, the audibility of the human voice has been improved, and the ears can capture more details, especially on several earphones that emphasize analysis. The style of Q5 further strengthens this feeling. The sound of the high-frequency part becomes more charming, the extension of the extremely high-frequency part becomes easier and more natural, and the permeability of the sound also reaches many steps. Even when the volume is high, there will be no uncomfortable sharpness. The difference between single-ended and balanced output of Q5 under the same earphone is auditioned. The conclusion is that the improvement of the latter is obvious. This improvement is reflected in better control, better resolution and richer sound levels.

and Q5's own style, my feeling is that it continues from X7 Mark II, which is a familiar and positive style that emphasizes sound restoration. Just like on X7 Mark II, I also like to adjust the gain mode of Q5 to the "high" gear, which will make me feel better. In terms of thrust, the two earplugs I chose to match this time naturally needless to say, Q5 can show their style well. Even when matching HD600, I think its performance has reached the level of "one can listen. The sound style and quality of Q5, which continues to Feiao's flagship player, I think it is naturally very willing to see users who still prefer bundled systems instead of music players. After all, the price of Q5 is almost half of the latter.

From the functional point of view, Feiao Q5 basically covers all kinds of functions that users can think of on a portable decoding earpiece product. Its sound quality performance can be regarded as the first-class level in the current portable decoding earpiece. The workmanship part not only maintains the advantages of Feiao's new generation of products, but also further improves the details... All these kinds of things, Feiao Q5 can be regarded as the "all-round responsibility" in portable decoding ".

if you choose a portable decoding earpiece at the price of 2000 yuan, Q5 should be a choice worth considering. However, if we jump out of the portable decoding earpiece market and look out, we will find that Q5 faces more and more portable lossless music players with more and more complete functions and "take all" characteristics in all aspects. How to emerge from these products may be the problem that Q5 needs to consider for portable decoding earpiece products.
