can reduce fever, Philips headset savior, Feiao K5 PRO ESS version tossing experiment
used Feiao K5 PRO(ESS version) for several hours to summarize it. There was also some confusion and exploration during the period. The content is slightly longer, all dry goods and doubts.
little hands praise!

K5 PRO ESS is suitable for people who have little desktop space or are very crowded (such as me);
people who worry that earmuff products are IQ taxes, rational and have a little fever at the same time;
people who want to further experience the potential of flat-panel headphones, moving-coil headphones, moving-coil in-ear headphones, and active speakers.
people who want to experience the sound quality of apple music conveniently and immerse themselves (no need to purchase another camera kit, buy Feiao LT-LT3 directly connected to Apple mobile phone and K5 PRO)
people who feel that the 100 to several hundred dollars in their hands are not as shocked as expected.
like advanced enthusiasts who are pure, powerful and have no obvious sound.

is not large, as above.
painted black metal is quite exquisite, which is much better than the K5 (first generation) I got from the "audio network" seven or eight years ago.
will have a small feeling that "this thing is quite advanced.

for some enthusiasts, its regret may be that there is no balanced output port for headphones.
but this single port (& phi;6.35mm) is actually enough. In other words, I have become more and more addicted to single-ended headphones recently. I often feel that headphones have better rhyme at single-ended.
(K5 PRO ESS version provides 3.5-to -6.35 adapter plug)
the huge knob infinitely rotates, the volume can be adjusted very delicately. But for some headphones, it is not easy to turn the volume smaller and more subtle.
On the left side is the switch between the gain (hardware) and the three input modes (spdif, line, and usb).

facing different input signals, pay attention to switching different modes through the lever.
three lever is slightly shorter than some larger machines, but it can be adapted.
S corresponds to optical fiber and coaxial (the optical fiber port of IKKO ITM03 and the 3.5 rotation of M11 are tested to be coaxial, both of which are very useful and have no abnormality)
L corresponds to the RCA analog input of the machine.
U corresponds to the USB-B port (square) at the back of the machine. There is a long thread USB-A to USB-B in its package, which can be used even when computers are used to build PC-FI.
The volume knob is also used to turn on the machine. Turn it clockwise from the initial position.

is the coaxial input port, and next to the optical fiber port. RCA analog input and output, this estimate is connected to the speaker and amplifier. I don't have the corresponding line in my hand, so I haven't tossed this one for the time being.

The back of the machine.
the USB IN here, the USB ports of mobile phones and portable HIFI players can be connected here through corresponding wires.

Connect to ZX505 based on USB mode:
connect Sony ZX505 and K5 PRO with Feiao LD-TC1(USB-C to USB-B).
A prompt "Connect to K5 PRO USB" appears on the player interface of ZX505. After confirmation, the volume and sound effects of ZX505 are all locked (cannot be operated). At this time, you can enjoy the sound quality of K5 PRO output.
the sound source of this mode is based on local music, if you have enough content, it is naturally good. However, considering that it is not easy to synchronize music downloads of several streaming media to walkman playback software, I think it will be very cheap to consider Taobao to buy HIRES-grade music.

is connected to Feiao M11, which can be based on coaxial mode or USB mode:
① The 3.5mm earphone port of Feiao M11 portable player can output digital signals coaxially, and K5 PRO can be connected with corresponding wires.
② Like the above ZX505, M11 can also be connected to K5 PRO through the USB-C to USB-B line. At this time, the Feiao Music APP interface provided by M11 will also pop up a corresponding prompt. After clicking OK, you can feel the high sound quality output by K5 PRO.

Connect IPHONE or Android phone, based on USB mode:
is realized by purchasing the corresponding line of Feiao (50 yuan to 80 yuan).

If the APPLE MUSIC of the iPhone is used as the playback source, the volume adjustment will be locked and the "volume line" on the APP will turn gray.
If you play "Lossless" music, the volume knob of K5 PRO will emit blue light. If you play "High Resolution Lossless", it will emit yellow light as shown in the above figure.
(instructions: the same Apple phone, the same line connectionLakers V380 Decoding Earring All-in-One, the "volume line" of the APPLE MUSIC APP interface can be adjusted, but it is actually locked, with good sound quality and better sense of space. When switching to the unprecedented CMA12 decoding ear-to-ear machine with the front end and the line, the volume of Apple's mobile phone is adjusted casually without locking, but CMA12 can still recognize files with different adoption rates, and the sound is vaguely not good enough and unstable.)
Apple Mobile Phone+ Ikko itm03(3.5mm earphone port and fiber port are shared), useoptical fiber lineis connected to K5 PRO. At this time, the "volume button halo" can also emit different lights according to different sampling rates, but the volume of the mobile phone can still be adjusted. At this time, the sound quality is almost the same as that in USB mode. But the psychological level always vaguely feels that USB mode is better.
Android phone, my VIVO T1 is connected to K5 PRO through Feiao's usb-C to usb-b (square port) line. When Haibei Music APP is turned on on the mobile phone, there will be a USB identification prompt of K5 PRO. After clicking OK, you can listen to music in the best state. Like the small tail (decoding ear line), when the volume is adjusted, "USB software volume" will appear at the top of the APP interface ".

, it is obvious that Feiao K5 PRO ESS version is more than enough for driving small earplugs. It is quite pleasant to match Feiao's FD5, FD7 and FH5S, with full dynamics and remarkable layering and strength. Compared with the mid-range and entry-level small tail of conventional design, it also has enough advantages and adaptability to hard-to-push headphones. Therefore, it is more suitable to show the high dynamics and large bandwidth of high-resolution audio.
compared with the first generation K5 seven or eight years ago, the K5 PRO ESS version launched at the end of 2021 has made certain progress in quality and listening sense, and also has certain inheritance (similar).
progress is that listening is more natural. What is inherited (similar) is that Feiao's "Zhongzheng and slightly neutral" can be detected vaguely ".
is sure that it will not be "partial" and it will hardly affect the characteristics of the earphones themselves. For example, some earphones have a soft Q-play side, so under K5 PRO, this style of earphones can still retain this characteristic.
on the whole, as far as the earphones I match are concerned, they are very pure and strong enough. Quite HIFI.

headphones, the most easily pushed in my hand are SIVGA SV005 (which seems to be discontinued) and SV021 (which are hot models in European and American markets). The former performs very well in pop music, with warm voice, mellow voice, fierce bass, excellent overall thickness and a very enjoyable feeling.
is easy to push, at this time K5 PRO will turn on the low gain and the volume will be about 50%.

SV021 is really very transparent, but its interpretation of some pop music is not likely to surpass SV005, which slightly shows HUFI, why? Because SV021 will not have a particularly concentrated and thick mid-frequency flavor. It is better at dismantling musical instruments (with good medium and high frequency quality) and showing a three-dimensional surrounding sound field.
SV021's low-frequency sense and mid-bass energy are not as full as SV005 under K5 PRO, but under the unprecedented CMA12.
under K5 PRO, what attracts me most about SV021 is its degree of separation, its simple and neat explanation, and its sound is smooth and correct, which has a brighter sense of hearing than SV005. At the same time, it, like MDR-SA5000, SHP9500 and TH900MK2, has stronger expressive force to thin female voices.

SHP9500 under IKKO ITM03(600 yuan decoding ear line), the hearing is full, the timbre is slightly warm, and the separation degree is good, but the knot image is slightly less stiff.
When you access the K5 PRO ESS version, the gain is low. When the volume is 60% to 70%, the satisfaction is very high, and the fever is almost reduced ". Female voices, musical instruments, and bass all have a very moving sense of music. With a harder and fuller knot, this is a sense of hearing that all the decoding ear lines in my hand cannot achieve.

years ago, because I was poor after buying it, I listened to the first K5 for a long time (despised by all kinds of people). What I was sure was that the K5 of that year could not make it sound. The sound is dry, hard, not moist, and lacks good control over low and high frequencies.
K5 PRO ESS version has made obvious progress in pushing TH900MK2 compared with K5, which has been heard for a long time. It already sounds very good. It is embodied in the two points of "nature and relaxation.
I think if it is not very picky, the combination of IPHONE(APPLE MUSIC)+ K5 PRO can already push one of the most difficult headgear in history.
(but a better way, perhaps a split combination of independent decoder + independent earpiece, which will have higher quality bass and treble, and the sound field will be more complete)
We recommend that you have a medium or high gain.

the German ultimate signature master monitor flagship.
Under K5 PRO, it is almost different music with different feelings. Occasionally, it is slightly stiff, not moist enough, not very "fleshy", not pleasant to listen to, and occasionally it is not bad. In contrast, the German Lakers V380 will show a more relaxed, natural and transparent sound quality. Only the V380 is selling for nearly 20,000.
K5 PRO and V380, similar products of nearly 20,000 yuan, have a difference when pushing the ultimate monitoring flagship. The voice of K5 PRO is relatively soft, and V380 is more pure and clear (not derogatory "hard"). The more difference between the two is reflected in the "sound field". Although the analysis seems to be quite good, the sound field of V380 will be expanded to give people a more relaxed atmosphere (the comparison is based on the same loudness).
However, these differences are sometimes even imperceptible. Therefore, to buy earmuff products, still have to do enough homework......

is unexpectedly pleasant and occasionally sharp, but most of the time, it is controllable, and you can call up a very suitable "sense of hearing" through gain and volume ".
I listened to the MDR-SA5000 after listening to the SPH9500. I felt that the two headphones had a similar balance and both had a good expression of Japanese female voices.
but the difference is that the MDR-SA5000 has stronger medium and high frequency energy, and the density and control of full frequency are more extreme.
is just this extreme in exchange for the "non-tolerance" of music files at certain times, that is to say, it is not as good as SHP9500 occasionally.
feel that MDR-SA5000 will have the kind of paranoia in their bones that is too sharp. By the way, SA5000 is closer than SHP9500 about vocal distance.

miniature flat-panel earphone TINHIFI P1 PLUS, which has great potential and is very nice to match with K5PRO. Analysis and moistening are available. Feeling of fever.

pushing JH3 is also very good. Even if JH3 is so good, it can still move more people through K5 PRO.

pushing Weston PRO X30, the human voice, analysis and positioning sense are very good, but relatively, the human voice will have a bigger mouth shape and more sincere emotion than when I listen to it with small tail products.

, I think IBASSO DC04 is a good decoding ear cord that can push IER-Z1R well, and it is also the lowest balanced audio accessory that pushes IER-Z1R well.
now I think single-port push IER-Z1R, the lowest audio device that pushes very well is Feiao K5 PRO.
atmosphere, moist, fierce, loose and bright. It sounds good. But I still hope the sound will be brighter.
(Single port seems to make IER-Z1R brighter)

push HD800S, the sound quality is good, the control is good, it is natural and listening, and it is very good.
but not very enjoyable, loudness is not enough, even when the gain is high and the volume is high, it is not particularly brilliant. It can only be said that it is not bad, but it is not suitable.

is similar to HD800S. It needs to turn on the high gain and the volume as loud as possible. However, it is better than HD800S. The MDR-Z1R at this time is already very good.
analysis is very good, the human voice is more natural, not cold and hard, the sense of space is quite good, can calm down and listen to some songs. Only occasionally there will be a rumbling mid-bass take-off and hit the head.
(instructions: MDR-Z1R are all adapters for Sony's official balance line balance to 3.5)
To sum up, K5 PRO is a good thing.
