all-round HIFI companion-Feiao Q5 Bluetooth Ear Decoder All-in-One Experience

Feiao brand has developed a very complete and high-span product line from the national brick era, from players to earphones, earplugs, and even its own peripheral accessories (recording lines, earplug upgrade lines), from low-end entry to fever flagship, which can bring a variety of choices to audio players. The Q5 Bluetooth Ear Decoding All-in-One Machine recently introduced can be said to be one of the most integrated all-round portable products in audio products I have ever seen.






Feiao Q5 is a quite "cross-border" product. From the perspective of product characteristics, it pays as much attention to the pursuit of sound quality as traditional Hifi equipment. From the perspective of product function, it is different from ordinary equipment, focusing on function expansion and playability. This has created a particularly interesting portable audio product. It is really a headache in the author's eyes to introduce it in detail in a limited space.

aside from hardware selection, Q5 is essentially an audio decoding and power amplifier, and the rest of its functions are attached to the decoding power amplifier. In today's portable audio market, it is better to do DAC AMP than to do one of them alone. Pure audio decoding needs to be bundled with a rear-level earpiece, which involves the quality of the recording line and the inconvenience of bundling and carrying. Pure AMP is even more unrealistic. At present, mobile phones and thin players, the main music listening players of mass users and even some enthusiasts, have few models equipped with LO output ports. What is the use? Therefore, the choice of Feiao is very wise. The portable audio all-in-one machine can obviously improve the sound quality of mobile phones and entry-level players, and at the same time has no great impact on portability (especially when wire connection is not required). When used in a fixed way, it can be connected with external power supply and a set of entry-level PChifi listening system can be set up (it can even be further matched with Feiao's K5. At this time, I have to mention a big killer of Feiao-like some of my own players, it supports the replacement of the ear module on the "chin". With the blessing of double AK4490EN, users who are not satisfied with the AMP part can replace the module of this part by themselves, and Feiao conscientiously provides a 3.5 interface and a 2.5mm balance interface on the default module, it is reasonable to meet the basic needs of most users.







(Feiao Q5 comes with a wealth of wire fittings, including mfi-certified lightning patch wires)

is not to say much. As a portable product, color value and workmanship must be a link that cannot be ignored. Of course, this is what Feiao has been very good at since the era of national bricks.
the foundation of aluminum alloy, CNC cutting, wire drawing process of the front panel, there are some shadows of the second generation of their own X7 under the hale and hearty shape, but the complicated oblique section process on the side is omitted, and the roller is embedded horizontally into the fuselage, but the overall face makeup still has a certain family-style sense, while the leather layer on the back is slightly higher than the metal surface, in addition to improving the beauty and stress, in terms of practicality, it can effectively avoid contact wear on the ear holder itself or the front end during the binding process. The round chamfer, the red embellishment at the switch, and the warning lights with different colors in different modes make Feiao Q5 more like a portable EDC than a desktop plaything for otaku enthusiasts.






in terms of hardware, Q5 uses two AK4490 as DAC chips, one for each channel, forming a balanced decoding module. AK4490 is a high-performance model in AKM product line. From the actual specifications, AK4490 supports DSD and PCM very well. With XMOS USB scheme, it can eat all common DSD audio files, and AK4490 can decode 28Mhz DSD files, according to THD N and other acoustic distortion indicators, AK4490 is a very strong DAC on portable devices. As long as the design scheme is normal, DAC part cannot be the bottleneck of Q5.
is that according to the architecture diagram of Feiao's Q5, Q5 seems to be a two-stage operational amplifier system. It passes the OPA1612 of two pieces of German instruments first, and then the external replaceable AMP module. What kind of sound quality this design can bring depends on the sound performance. As for the RGB prompt working status, dual mircousb interface and other functions provided by Q5, it can be regarded as the manufacturer's emphasis on human-computer interaction experience, which is also lacking in traditional HIFI equipment. I have to say that Feiao still has "Internet thinking?








Q5 is a highly functional audio all-in-one machine. The author simply lists its "skill points" directly:
1: Under USB input, Windows, Mac\Linux users can directly connect Q5 through USB wires. After the driver is installed, Q5 becomes a USB sound card. The USB scheme of Q5 is XMOS, which can provide a good sound quality input processing scheme.
2: For mobile devices, Q5 supports iOS and iPod devices that are compatible with a full range of Lighting through wires with MFI certification, and supports Android devices with OTG function. The author also accidentally found that through WM-Port wires, it can be compatible with the use of Walkman devices.
3: In addition to common USB inputs, Q5 also provides these interfaces for devices with optical fiber and coaxial output. At this time, it is not necessary to directly connect Q5 DAC through XMOS USB ADUIO. This mode is more convenient to use and does not require driving.
4: If only the AMP part of Q5 is intended to be used, Q5 provides a line input port. At this time, Q can be used as a portable ear.
5: If your device does not support the above methods, Q5 also provides a big trick, that is, Bluetooth input, which eliminates the trouble that the mobile phone does not support USB DAC. Digital audio is transmitted through Bluetooth, decoded and amplified at Q5 and output to headphones. However, the sound quality at this time is affected by the Bluetooth encoding support level of the mobile phone, while Q5 itself can support Qualcomm's apt-X HD transmission protocol at most.

so many functions, although they do not conform to the usage habits of most users, they cover the usage scenes of almost all ordinary players and even enthusiasts. Therefore, in order to prevent Q5 from becoming a chicken rib product that can be embroidered twice, Feiao must make more efforts in sound, which is also the link that the author is most looking forward.
equipment matching, the author will not have much difficulty for such a portable product with a price of only over 2,000 yuan. The main front ends are two representative ios/Android devices, ipad and Note8, and a national brick with LO output (the recording line is L16 sold by Feiao). The earphone is based on the more positive In-Ear PP8 and UE600, and the "taste" Sony E741, and portable headwear MDR-1A, PS500, etc.


Feiao Q5 is unsurprisingly still a clean and transparent route of quality flow, emphasizing the amount of information and the extension of both ends. Although the high frequency has sufficient brightness and extension, it is quite grasping at first glance, but after listening carefully, the whole is slightly off the plate. The low frequency is abundant and strong, and the medium frequency does not add any obvious monosodium glutamate seasoning for "popularity, however, the clear and beautiful style is relatively suitable for the interpretation of female voices. The shape is moderate in size, and the vocal position is relatively close but does not appear to be close to the ears to take into account most of the instrumental performance. The performance of sound field and separation degree is excellent, not to say how big the sense of scale is, but the ratio of depth to horizontal brings a good sense of encirclement, with obvious edge traces without appearing empty, laying the foundation for regular and orderly instrumental music arrangement, and being competent for most pop, rock, Live live and small music, especially when listening to the piano, you can have a very beautiful overall tone and overtone performance.
, in terms of the quality of Bluetooth mode, the AAC code of ios and the apt-X of Note8 are sufficient in information, at least when listening to pop music, you cannot feel the obvious problem of weak resolution. If your mobile phone is a low-end Android machine that only supports the most basic SBC code, it is still recommended to purchase another OTG wire for matching.


headphones are matched, the author does not recommend earplugs with thin intermediate frequency or too clear timbre to match Feiao Q5 earphones, otherwise the sound will be slightly exciting and the intermediate frequency will not be full and thick enough. The traditional middle and low resistance moving ring earplugs, high density moving iron earplugs and most portable headsets can be said to be completely out of the question in front of Q5, and can ensure the original "flavor, it brings obvious improvement to hard qualities such as analysis, image formation and sound field. Of course, users who like to move and hit times can turn on the switch of low frequency gain. It can bring sufficient low frequency reverberation, further strengthen the diving strength and effectively enhance the sense of atmosphere. However, in this mode, the author thinks that it has some influence on the detailed performance of intermediate frequency, but as a" condiment ", it is a good way to play. However, in the author's eyes, Q5 cannot be used as a "serious" listening tool in sound. In terms of dynamic, high-frequency transient and low-frequency resolution, Q5 is not so friendly to classical music lovers. In this respect, Q5 cannot be given too high expectation value.



, it is not difficult to see that Q5 is perfectly supported by integrating Bluetooth, decoding, (replaceable) earpiece and balance functions except that it cannot directly insert TFC card to play music for you. It is also a portable HIFI partner that integrates Bluetooth, decoding, (replaceable) earpiece and balance functions, and can go to Apple, Android, PC and PC. It can even make a physical button with low frequency gain on the earpiece to improve listening. The performance of the sound part is remarkable, but it is not beyond expectations. As a product that only sells for 2298 yuan, it is useless. It takes a relatively restored and pragmatic quality flow route, and there is no need to worry too much about the lack of taste.
the author can't think of a more appropriate word to describe it except "omnipotence" for the time being, or it breaks the author's previous concept of the word "omnipotence". Objectively speaking, it can also be regarded as refreshing the upper limit of playability of portable earpiece products. Feiao's "cross-border" masterpiece really makes the authorhad to admire.
