Preamble:
Unconsciously, I have gone through thirty or forty years of feverish road, from speakers to amplifiers, from walkman to audio, from PC HiFi to home theater, from IEM earbuds to head-worn big ears, from portable to desktop, from decoding to headphone amplifiers, and now if someone asks me what is my biggest dream? There is only one answer: open your own coffee music listening studio! More and more, I feel that music + coffee = the ultimate companion! Because whenever I review and play with the equipment in the dead of night, there is always a cup of my own hand-poured Italian latte on the table, its mellow aroma and charm linger and infect me, and drinking coffee while playing fever has become the most enjoyable part of my life. If it is said that the headphones and equipment can be so closely and harmoniously linked together, Shui Yueyu should be regarded as the first to bear the brunt of the precedent, it can be seen that this HiFi brand is both very enthusiastic and brainy,

Appearance, Wear and Performance:
1. As the most expensive flagship headset of Shuiyueyu, from a design point of view, it has a lot in common with its other headphones, the shape of the headbeam and all metal or aluminum frames is very large, it is a pair of heavy headphones, it is certainly not the first choice for a pair of headphones you want to use outdoors. Because the metropolis has open ears, everything you hear will leak into the world around you, so I don't even like to sit in the attic study and wear it, because not only will it affect my wife who reads and prepares for exams, but also because any external sound will affect the quality I am appreciating, so I just take advantage of the best time for my daughter to study in college to rub her boudoir, and wear the metropolis to plug in and out of the decoding headphone amplifier at full volume, which is really enjoying music alone, Gain insight into the potential of these headphones and let loose your personal space.
2. The headband on this pair of headphones uses a suspension system, I was surprised to find that it is very comfortable to wear, there is no squeezing feeling, even though it is a pair of all-metal headphones with a bit of weight, I didn't really feel the weight on the top of my head, the ear cushions are huge, but they are very soft, this is definitely an over-ear ear cushion, the pinna definitely does not touch these ear pads, it is very easy to remove and replace the ear pads because it is magnetic. The all-metal structure does not see a trace of plastic parts, and I have no resistance to the metallic headphones, and the industrial head beam is matched with the leather cushioned leather headpad, which is very retro and nostalgic. The headphone parts are connected by hexagonal bolts, which makes it look wild, but this complements the overall design that is very modern and minimalist.
3. When you get this big Metropolis, you will immediately think, is this big ear difficult to control? Considering that Cosmo's 100mm diameter diaphragm module is far superior to traditional planar magnetic headphones and comparable to electrostatic headphones with low split vibration and is equipped with unique FDT (Full Drive Tech) comprehensive drive technology, I am not surprised, in fact, the Cosmopolitan built-in ultra-thin low-tension vibration diaphragm substrate with a thickness of about 500nm and a high-elasticity ultra-thin sterling silver circuit are not so difficult to push, and the small tail and portable decoding headphone amplifier can basically meet its wide frequency band, Low dive and fast detail response speed, the Metropolis comes standard with a very beautiful braided cable, And use the 4.4 balance plug,Insert the left and right channels of the large ear cavity of the double 3.5 plug versatility is very good,I have tried to insert the Sony Z7M2 original Jinbao double 3.5 to 4.4 balance line can be fully matched,In addition, Shui Yueyu also comes with a 4.4 balance to 6.35mm adaptation wiring (this is the first time I have seen a manufacturer so thoughtfully predict the natural habit of our burners), which means that we can plug this headset into any decoding earphone amplifier or player, Of course, in order to make it play an extraordinary high quality and great dynamics, it is absolutely indispensable to match a high-quality decoding headphone amp or even a desktop all-in-one computer, and I have tried it on different decoder headphones one after another: Onishi Miracle suit set machine, FiiO K19 flagship machine and Yulong Asura digital broadcast machine, I found that the timbre presented by the metropolis in different amplifiers is still different, and its potential and expansibility can be seen.
Equipment matching and hearing sharing:
1. The impedance of the Metropolis is only 15 ohms, and we will immediately think that it is easy to drive, I want to say that in terms of volume, if you plug it directly into a portable player or even a mobile phone or computer, you can get a relatively large volume, but if we don't use a DAC, we can't fully enjoy this pair of headphones, it's impossible to get any decent impact in the low frequency band, everything sounds relatively flat and dull, of course, if you listen to it in a straight way, the Metropolis estimates that most burners shouldn't do it, Even if you plug this pair of big ears into a less expensive headphone amp, it will indeed bring this pair of headphones to life, and the metropolis will immediately have a certain impact in the low frequency band, of course the low frequency part it will not give you a subwoofer type subwoofer, it will not rumble in the low frequency, and it will not stay and stretch too much, it is a pair of headphones with a very fast response to the low frequency, in fact, this is perhaps one of the headsets with a faster low frequency rebound I have heard, I can hear the change with each hit of the drum, If you're a bass controller, this Metropolis might not be the best choice for you, at least not because it's not designed for that type of headset, but I don't think its low frequencies are flat and weak. The same goes for high frequencies, and it's impossible to get a satisfactory brightness out of the treble with a small tail or decoding the amp, and the treble becomes bright and clean with a small tail or decoded amp, but not harsh, and picks up every subtle note very accurately. The real highlight of the Metropolis is the midrange, and I think it's so impressive in terms of the similarities between the male and female vocals as well as the instrumentals, and when it comes to the midrange, it's probably one of the better big ears I've ever heard, and it's fair to say that this big ear can almost compete with a lot of more expensive headphones because it has its own characteristics, and that's the pair of headphones you want, and I guess you're not going to pick and buy a pair of big ears that sound like other headphones on the market, and since the Met has an open design, Obviously, it has a very open and wide sound, and at the same time it is a headphone that focuses on details, as long as it is paired with a decoded headphone amp, you can feel relatively fast low frequencies and rich details, but not excessively, not too harsh, the key is not to easily cause wearing pressure and listening fatigue.
2. Next, I will briefly talk about the Onishi Miracle personal audio center that toured and auditioned with the Metropolis of Water Moon and Rain, I have previously evaluated in detail this set of excellent quality inside and outside can be called the first echelon of the three-piece suit of the desktop, of which Onis comes with DAP player XM10 can directly drive almost most of the IEM earbuds on the market, with high gain, clean sound, good sense of space, more advanced vocals, good sense of music layering, and the sound field is relatively wide in terms of direct push, In short, the driving force of this digital broadcast is one of the more abundant on the market, which can give most IEMs sufficient volume and sufficient sound pressure, and the output effect can be heard very carefully in a relatively clean and solid degree. After switching to its own Prime mode, there is a good sense of warmth, and the feeling of surrounding the whole space, the whole ear and the head, a very flattering British warm tuning, and the best thing is that the background is relatively pure, with this XM10 player is a good catalyst, so that you feel more engaged in listening to music, but in the case of such a sufficient drive, what is the effect of XM10 directly pushing this metropolitan headphone? Listening to "Chen Jieyi - Stubborn", as soon as her voice comes out, you can't guess that it can create a sense of more open space, the feeling of the afterglow output in the big ears is just right, as if it is the feeling of singing in front of you, I think it is also a very stable sound bottom, I will not say that it is a simple digital broadcast DAP playback with soft feet, but of course I can also hear it in some positions, or some more complex situations, you sometimes feel that it is not very complete output to you, Under the premise of high gain, most of the details can be basically presented more realistically, but I think the drum sound can be a little more solid, but now it's basically on this headset big ears, and I think the density and low frequency can be launched, in fact, for only one digital player, DAP direct push, I think it's quite qualified.
3. After trying XM10 with Shuiyueyu Metropolis direct output, why don't we try to connect XP10 to the matching set of pre-amp decoding headphone amplifier XP10 try to use the same headset and listen to the same song again, plug XM10 into XP10, switch to the digital player DAP source input mode, in the drop-down menu of the digital broadcast operation interface, you will see XP10 start in this position of normal mode, and you will see some controls of digital broadcast DAP, For example, when you turn up the volume, you will actually see it adjust in sync on the screen; In addition, these headphone modes, big ear modes are all available, and when you connect to XP10, the gain is no longer just low and high, it is divided into low, medium and high gain, there are many XP10 settings below, I think the biggest impact on the sound is a function called SRC, in fact, there are many fans who play digital players will know that it is a sample rate conversion function, usually playing Android digital broadcast will cancel the SRC bypass, on ONEX in fact, it can also allow you to convert other different bitrates, You can also play DSD, or you can upscale it to 96kH-192kHz. In addition to using this digital broadcast control decoding headphone amplifier XP10, the mobile app called Eddict player installed by the mountain spirit player can also control the ONIX set of desktops. Now let's focus on the XM10 digital broadcast, direct push water, moon and rain metropolis and the effect of using the Miracle machine suit to drive together?! Obviously, the fineness of the instrumental music and vocals, softness, and clarity have been significantly improved compared to the direct push just now, and the voice of the entire lead singer is different, now it is calm and comfortable, and this song itself belongs to that kind of comfortable and natural style, this combination will not forcibly push the low frequency higher, and its overall low frequency volume strengthens the control and robustness compared to the direct push with the number of broadcasts, it will make the high, medium and low three frequencies smoother, and the taste of the sound fever taste and high-definition sense and fullness will be heavier, in addition, The sound field of the metropolitan space is relatively wide, and after this combination, it is obviously larger, and the suit set can be said to play an ideal companion for the metropolis with a good sense of three-dimensional space quality.
4. The XPS10 linear power supply at the bottom of the Annis set is also worth playing, we will see that there are many different settings built into the power supply system, theoretically the display will interfere with the power supply, so turning off will be more beneficial to the purity of the sound, of course, for me, it must be set to always-on, and the screen full of ritual and professionalism is also one of the highlights of this suit. First of all, the power supply can be set to 17.5V to 18.5V, in fact, it is within the safe range of the power supply, we don't have to worry about the voltage set too high and affect the function, now switch to the jazz female voice "Chlara-True Story" Try 17.5V first, of course, the change in voltage output value is not too obvious in the sound difference, with the gradual increase of the output voltage, there will be a little more in the vocal high-frequency density, and the bass will be more condensed, which will make me feel that the cleanliness and extensibility of the sound bottom will be better, of course, my most used occasions are simply to increase the voltage directly to 18.5V, as for the subtle differences that exist, it is left to everyone to match different headphones according to their own tastes and more effort to find the fun of playing with equipment.
5. Water Moon Rain Metropolis with Onishi Miracle set, 4.4 balance, choose to listen to the "2024 Shanghai International High-end Audio and Video Festival Commemorative Edition" audition disc, play the second song "Tong Li - Taihu Lake Beauty" You can judge that the quality of detail restoration and precise positioning of this combination is so excellent, the opening four guzheng plucked strings can obviously let the listener perceive the position of the instrumental music and clearly place it on the right side close to the recording microphone, and the flute playing behind the left channel of the microphone is slowly speaking. In front of the microphone in front of the recording scene, the vocal swallowing and ventilation breathing details of the vocals are fully displayed, and the high-frequency performance ability of the Water Moon Rain Metropolis completely interprets Tong Li's signature soft, sweet, and delicate female voice like a water town in the south of the Yangtze River to the fullest, and the vocal teeth in the heroine's treble area are controlled just right, the high-frequency band is steady and not floating, pure and smooth and sweet, and the time of the vocal reverberation in the space has a kind of unfinished residue, The three-dimensional sense of the left and right channels is full of air, lingering around the entire brain and ears, at first glance, it seems that this set of water, moon and rain metropolis + Onis Miracle system is a nearly perfect saliva fever female poison artifact tailored for Tong Li, a fever female voice.
6. Water Moon Rain Metropolis, with FiiO K19 vs. Onis Miracle, 4.4 balance, listen to "Berlin Sound 3", by comparison: play the second "Niccolo Pagainini-Sonata Concertata Sonata" classical small arrangement, which is included in "Paganini For Two-Gil Shaham, Göran Söllscher, Niccolò Paganini" This is Paganini's first sonata for violin and guitar, and the shadow of the classical period can be heard in the balanced musical structure of the piece and the interaction between the two instruments, the first movement of this sonata is characterized by a relatively uniform distribution of melodies, the guitar sometimes imitates the violin and plays in turns, rather than strictly playing the accompaniment part throughout the piece, and the violins and guitar also make some calls and responses, The unique expressiveness of both instruments is demonstrated at the same time. After careful and repeated comparison by AB, the high frequencies of the Metropolis and the Annis Miracle set are more translucent and slender, the sound of the violin is more delicate and grainy, and the sound of the guitar playing the plucked strings is more crisp and cheerful like a jade bead falling on the plate; Another point,The difference between the two decoder headphone amplifier integrated desktop machines is that the Miracle hall sense is more aerodynamic,The space reverberation is more three-dimensional shape body feeling,The middle and low frequencies of this combination are thicker, which makes the tuning trend in the high frequency and high and high frequency bands more thicker,Relatively speaking,Shui Yueyu will be paired with a more middle and lower plate、More mellow OnisMiracle set is slightly more grand in terms of sound field performance, For the interpretation of this chamber music, we take the water moon and rain metropolis with its own tuning bias that is silky and smooth, and with a thicker sound base, the Miracle machine can present the kind of classical salon music like a small party with a loose sound field and some aristocratic temperament, which is more likely to reflect the kind of incisive and incisive interpretation of Paganini's violin technique dazzle by the Italian famous piano, and in this regard, it is better than the tuning style of Shui Yueyu with K19, which tends to be a quality stream, which can better reflect the relaxation of this record. The beautiful ensemble of violin and guitar is as smooth and moist as enjoying a rich and mellow cappuccino.
7. Shuiyue Rain Metropolis with Yulong Asura, 4.4 balanced, choose to listen to the "Mei Xiaoqin-Fengyun" audition disc, first of all, Yulong Asura selected AK current flagship decoding chip ace combination AK4499EX+AK4191, which is also one of the most used DAC architecture solutions for high-end audiophile decoding headphone amplifier equipment. After an hour or two of warm-up and hard work on the equipment to warm up and struggle with the subtle differences in sound quality for a long time, coupled with playing with the different built-in clock modes and filtering modes of the machine, to be honest, there is almost no difference between Clock1 and Clock2 at first hearing under the premise of matching the water moon rain metropolis, and there is no obvious difference between the three filter modes (SLOW/SHORT/SHARP), therefore, I casually chose the SLOW filter with the Clock2 clock, at first, The volume is set to about -38dB, which seems to me to be just the right volume in the dead of night, and whenever I compare new equipment, especially when it is difficult to distinguish between Zhong Bo's two DACs or portable DAPs/DACs, I always use the audiophile female vocal album that I am more familiar with and easy to evaluate as the source of the sound, because this kind of music is professionally produced by a fever recording studio, with clear and rich high and low frequencies, pure vocals and a variety of but not cluttered instruments, which is very conducive to timbre comparison. The moment you plug in the Water Moon Rain Metropolis to play the 11th song "Rolling Red Dust", you can feel the opening guzheng in the center of the microphone and the slightly backward pan flute slowly lead to the lingering flute positioning is extremely accurate and clear, and the few national instrumental music has laid a rich texture and has a certain thickness of the middle and high frequencies, and the ensuing bursts of drum sound are moderately powerful, and there is no lack of solid and full low-frequency resonance in the tightness, and the low-frequency interpretation is so real and moderate under the blessing of the plane large diaphragm of the Water Moon Rain Metropolis, There is no not-so-in-the-best headbang effect, nor is there an exaggerated and artificially rendered elasticity, it is methodical and accurate, in other words, it should give you as much drum thickness as possible, and its low-frequency restoration is similar to a no-makeup female anchor who disdains to open the beauty mode is sincerely promoting a product that she can trust. As the volume increases slightly, the vocals become more emotional, and the bass becomes more solid, I am increasingly overwhelmed and attracted by its balanced tuning, almost impeccable and unexaggerated bass presentation, clear midrange and a wide and realistic soundstage without any harsh treble.
8. Water Moon Rain Metropolis, with Yulong Asura vs. Onishi Miracle desktop machine suit set, 4.4 balanced, and as the flagship ES9039PRO of another decoding chip manufacturer ESS, it is also the core DAC favored by many high-end devices, and it is not difficult for everyone to find that the duel frequency of AK4499EX+AK4191 and ES9039PRO is much more than that of AK4499 and ES9039PRO, the so-called narrow road to enemies, Recently, I just saw a female enthusiast moderator review and compare the two currently quite popular mid-to-high-end DAP portable playersONIX Overture and Shanling M5 Ultra, and these two devices are built into the ES9039PRO and AK4499EX we discussed today+AK4191, ES9039PRO is the latest flagship DAC released by the American ESS company in May 2022, which can be called the strongest on the surface, and there should be no difference between these two sets of chipsOn the one hand, in terms of cost, the ES9039PRO procurement cost is higher than that of AK4499 and the new AK4191+AK4499EX (may exceed 200 yuan), as we all know, DAC is only a small part of the cost of audio products, Qualcomm module, power amplifier circuit and material workmanship constitute the bulk of the cost, so the final sound characteristics still depend on the brand's audio engineers' research and development tuning skills, I remember that I had a detailed evaluation earlier this year of the XD05 Pro flagship portable decoding headphone amplifier, for the first time in the world to provide BD34301EKV, ES9039PRO and AK4499EX modules for their own replacement of DAC, although the sound of the equipment does not completely depend on the decoding chip, but the impact of different DACs on timbre, sound field and musicality Although you can try to change slightly through subsequent tuning, each DAC chip has its unchanged "background color" Thus increasing the playability. First of all, choose to listen to "Jakob Dinesen–Dancing Devil", to be honest, the two are in such a high price range and are equipped with flagship-level DAC chip architecture under the premise that its comprehensive quality will not have obvious three-frequency linear shortcomings, if the difference is only a slight tuning orientation, AB repeatedly compared, Yulong Asura (volume -20dB) sound fast, clear, musical, rich in detail, balanced and very emotional, Asura's innate musicality and accurate positioning of the stage ability emerges, the details are there, not too aggressive, it just acts as a porter of a straight male type to restore an effortless sound, the drum bass bursting out from the music is close to 18 seconds is impactful and not bloated, and the touching and charming male lead vocals of the young Danish singer and guitarist Jakob Dinesen that this group conveys are open and loose, The high-pitched area that is mainly the middle range feels like butterfly wings stretching out into space, there is a kind of floating on the melody that makes the whole music sound very sensual and realistic, and the three-frequency excessive listening is very healthy, and there is no special abrupt frequency band that makes it unnatural, no wonder the singer later released the first special male voice audiophile disc "Let The Hard Times Come" as the male lead singer of DALI Audio. Next, I'm going to talk about the overall listening experience of Onis Miracle (volume 70) with Shuiyue Rain Metropolis: it is very immersive, the details are restored in place and meticulous and can withstand the careful scrutiny of the listener, for the vocal expression of a feverish male voice like Jakob, it is full of emotional expression and appeal, and it is impressive that the wide sound field has twice the effect with half the effort for the setting off of the scene and the creation of the atmosphere, secondly, Continuing the British aristocratic temperament, the Onis console has a kind of sound that allows you to immediately calm down and enjoy its warm and infiltrated analog flavor, and the mellow and solid is its biggest timbre highlight, which is also the main sound feature of ES9039PRO flagship chip that is different from the AK home DAC.
9. Water Moon and Rain Metropolis, with Yulong Asura vs. Burson Audio Playmate 2, 3.5 single-ended, choose to listen to the 1,000-yuan audiophile disc of "Burmester Art For The Ear Berlin Sound 2", through comparison: play the fourth "Dabringhaus & Grimm Label-Konzertante Barockmusik Baroque Concerto", This piece of music is from one of the representatives of Baroque music Handel's famous disc "Harp Concerto In B Flat Major Harp Concerto in B flat major", first of all, Burson Audio Playmate 2 (volume 66), the overall tuning is slender and quiet, the background is pure black, and the degree of restoration is extremely high, it can not only show the details well, but also will not bring any harsh bad listening, like this classical harp part is clear and transparent and smart and light, The background orchestral unison part of the instrumental sound is rich but not messy, and the gently rolling synthesizer waves are accompanied by a wonderful and rich bounce, sounding lush, full and vibrant. Playmate 2 offers beautifully nuanced renditions that bring great immersion to your musical presentation. In contrast, the overall listening sense of Yulong Asura presents a thicker sound base, and the detail restoration is extremely excellent, you can easily feel the light and agile fingering of the harp player and the subtle changes that jump easily on the strings. The vocal instrumental music is conveyed naturally, especially the sense of space with just the right amount of breadth and various instrumental music to form a natural and balanced full-frame listening scene. If the most intuitive difference between the two machines is the price: the price difference of nearly double also forms a difference of nearly double the heat generation, it is obvious that Yulong Asura can be described as a big heater, and Playmate 2 is relatively docile. Listen to the first Norwegian jazz female singer "Radka Toneff - The Moon Is A Harsh Mistress", both decoded amps can express the natural voice of the lead singer and Steve Dobrogosz's textured and enveloping piano accompaniment, this perfect vocal and pure music accompaniment combined with mature and robust recording makes the whole piece fully distinctive: pure. The biggest difference between the two devices is the accentuation of the sound field and atmosphere, the female lead singer of Yulong Asura is slightly further back, the voice is more ethereal, and the vocal position of Playmate 2 is more centered, and the sense of presence is more immersive.
10. Water Moon Rain Metropolis vs. Olaire AR5000, with Yulong Asura, 3.5 single-ended, through comparison: play "Tan Weiwei - Hymn to Heroes" first, on the one hand, the impedance of the two big ears AR5000 is higher, but it is easier to push, and the volume can be adjusted to about -45dB to achieve a higher sound pressure level of the resolution detail comparison equipment, and at this time, the Water Moon Rain Metropolis must be increased to about -25dB to push to about the same volume. The two big ears show completely different grade levels under the collocation of Yulong Asura, as the so-called penny is worth the goods, the larger price difference makes the sound quality also more obvious, most of them are stable and atmospheric, the volume is very large and calm, and the tuning is mature; AR5000 vocal mid-frequency is more prominent, the fluency and moistness of the three-frequency connection are slightly less smooth, in about a minute Lu Siqing's violin accompaniment and the symphony orchestra chorus climax began to form a more obvious timbre difference, the texture and granularity of the pine fragrance of the violin strings that are mostly expressed in the city are more silky and shiny, and AR5000 is a little rough and loose in the expression of the violin solo part, which is a kind of control ability that can be calm. It is also a kind of stability quality of the formation of various instrumental coordination and resultant parts. Listen to the "Marlboro March" classical large-scale audition song, due to the advantage of AR5000's easy pushability, Yulong Asura only needs to open to -36dB under single-ended output to obtain a very solid, potential mining more abundant sense of energy and sound pressure level, and the metropolis is still relatively disadvantaged under single-ended, at this time, Yulong Asura's modulation volume is the largest 0dB still fails to feed enough, which shows that Yulong Asura's single-ended output power is far inferior to its own 4.4 balanced end output for large ears that are more thrusty, Therefore, in the process of testing the large dynamics and transient response of the equipment, the AR5000 can still express the relatively grand sound field and momentum of the track, and the single-ended push of the AR5000 by Yulong Asura is more than enough.
11. Water Moon Rain Metropolis vs. Sony Z7M2, with FiiO K19 flagship decoding headphone amplifier desktop (gain: super big ears mode), 4.4 balance, choose to listen to "Elmer Bernstein-The Magnificent Seven Marlboro March", through comparison: First, after comparison, these two big ears can clearly perceive that Z7M2 is a difficult guy to push, but in front of the metropolis it is still a relatively easy to push device, It can be described in this way: Z7M2 with K19 volume, under the premise of 70, most of the cities have to rise to about 90 to achieve basically the same sound pressure range. Second, the sound field presented by the Metropolis in the performance of classical large-scale repertoire is larger, and the specific analysis is that on the one hand, the middle and low frequency bands are more linear tuning characteristics on the Metropolis to improve stage performance, presenting a dynamic margin at the hall level, so that there is enough room for interpretation between the audience and the performers, as we all know, the spacious tuning can accommodate larger ensembles and is conducive to more expressive music, and it stretches the vocal image larger on the X-axis. Marlboro March" is such a big-scene track, and overall, the Met has a good job of reproducing the positioning of each instrument in the recording, with more adequate texture and clearer imaging on its oval stage, which may feel a little too stretched if it's a small salon-style choreography or a studio mix track, so I prefer to fill the space by manipulating the K19 EQ to boost the low frequency band, and bring the bass and the singer closer together for better intimacy. Speaking of which, I guess there are many Sony fans like me who want to retort that the Z7M2 is quite grand and expansive when listening to this classical classic track. Then I want to emphasize that most of the reason for this is that the huge sound field is based on the Z7M2's surging low-frequency atmosphere, which is super strong, so I have to talk about the difference between the bass performance of the two headsets: with Metropolitan Listening, I can hear and feel the rumble even below 50Hz, but it sounds relatively dense and responsive, with fast attack and attenuation, this bass is not as strong and impactful as Z7M2, The Metropolis does give you a sense of layered and precise bass, with more detailed bass sounding even at higher volumes, well-controlled distortion, and good headroom for bass rendering while maintaining three-frequency balance, in other words, better balance and cohesion in bass tuning. Switching to the live version of "Shan Yichun - Rainy Day Live" Chinese female voice, for this song full of rich low-frequency accompaniment in terms of female pop performance ability, Z7M2 in the opening few bass bass fullness and elasticity does play a certain decorative role in the seasoning and rendering of the scene, so that the single voice with high pitch and alto pad the solid and mellow sound foundation, compared to the taste of the high frequency of the metropolis is emphasized, it does a better job in retaining a lot of air and evocative details, Instead of making it like the Z7M2, the treble sounds more vivid and penetrating like a thin stream, and in the accompaniment of acoustic guitars, cymbals and other stringed instruments, the Met can emphasize transients and textures more clearly, and can more clearly let me hear the breathing details or the spatial remnants of the beat instrument, and the extremely high frequency part sounds real and not too sharp, thanks to the high frequency band and the bass and mid-bass do not interfere with each other to make the treble more prominent, Vocal and stringed instruments sound more open and airy, and the most beneficial thing is that a slightly sad quasi-mature female voice like Shan Yichun listens more mellow and sweet. As I mentioned earlier, the main reason why Shan Yichun's voice is evocative is that it includes the vicissitudes of midrange breath control, the vocal position of the Z7M2 is relatively more ear-bearing, but the rumbling and somewhat rendered low frequencies can sometimes mask some midrange details at high volumes, and in this regard, most of them are able to smoothly transition the bass to the mid-low frequencies, so that all sounds can be kept clear, and allow notes of different frequency bands to pass through the mix to express their opinions, providing good separation and playing out their own timbre. There is even a hint of warmth sometimes coming from the mid-low frequencies, which makes the vocals fuller and more pleasantly colored by clearly layering different instruments and capturing a lot of light detail in the mid-to-high range, which shows that the Met's strong distortion control ability provides good space for equalization across the frequency band, and adds additional harmonics and airy textures to enhance the saturation of the midrange, so to speak, with the K19 Metropolis Metropolis is perfect for pop, instrumental and ACG music.
Summary:
The Moondrop Metropolis has successfully inherited and sublimated the advantages of the MOONDROP planar magnetic headphone design, which is extraordinarily spacious but not empty, and the delicate, sweet tuning and manufacturing process are excellent for this price. This happens to be in harmony with the smooth and refreshing and light and peaceful taste that retains the original fruity aroma of coffee beans when tasting Shuiyueyu Medium Roasted Hanging Ear Coffee.
