This sound review will be based on the NOS setting activated, with HDR: ON. I have only used IEMs during evaluation.
(HDR: Off makes FC6 too susceptible to noise from the source (phone/laptop), introducing artifacts such as pops, crackling and a very loud noise floor. It is only really useable together with a VERY clean source.)

+ Rich, Velvety, Natural, Analogue, Liquid R2R NOS Timbre
When HIBY FC6 is run in NOS mode (No-Over-Sampling), it takes the signal as is and peddles it forward to your connected IEMs/headphones without tampering with it, without oversampling it.
What you receive in your ears is something your brain registers something untouched by processing. I hear how each note is de-flattened and expanded in every direction with a degree of richness that makes balanced armatures sound far closer to dynamic drivers in timbre than I thought was even possible.
This is a revelation. Transformative. It smoothes out any digital edges one might otherwise perceive with regular delta sigma DACs.
Something deeply, fundamentally correct is done to the music with this wonderful little dongle on NOS mode.

+ Sound Density
The HIBY FC6 infuses each note with a rich, dense sense of weight that also polishes the outer edge of the notes. I don't think I need to say more about it than that.

+ Tangible Notes
Because the density of each note is so satisfactorily high, the notes seem to take shape and really solidify in your ear-brain perception.

+ Depth Perception
What further aides the sense of tangibility is the sense of depth FC6 conveys. It even makes planar IEMs, which are notoriously flat-sounding spatially, sound adequately three-dimensional. Not only is the stage in which notes propagate deep, but the notes themselves expand in each direction and convey depth in such a way that I reckon very few if any chip-based dongles can emulate.

+ Polished Treble
Because the energy of each note originates in the middle of the note, the treble contouring is very smooth as the energy tapers off towards the edge of the note.

+ Expressive Micro-Dynamics
The FC6 has a knack for digging into each note and unearthing the very inner core of it for your enjoyment. It reminds me of the Questyle M15 in this sense, but the difference is that the M15 has an awful ESS-glare and a flat, squarely 2-dimensional, narrow presentation whereas the FC6 is deliciously natural & 3-dimensional; complete opposites.

+ Anti-Shout Effect
FC6 by virtue of its R2R arcitechture, I'm sure, is tuned in such a way that it seems to transform anything overly bright, glary, shouty, binary (where something binary is defined as the anti-thesis to dynamic) into just more musical enjoyment. It just seems to synergize well with balanced armatures and planar IEMs both of which do not possess an inherentely dynamic character like true dynamic drivers do, but provide heightened technical performance and resolution capacity over dynamic drivers.
FC6 pairs well with brighter dynamic sets but cannot showcase its full benefits with smoothly tuned sets, particularly smooth, inoffensive dynamic drivers where the richness becomes too much of a good thing, robbing the music of much needed bite and vitality.


+ Unprocessed
As alluded to before, the FC6 sounds wholly unprocessed. To understand what that might mean, let me try to describe what I identify in every chip-based DAC.
Chip-based DACs make the notes sound artificially contained, microdynamically veiled, spatially flat in terms of depth and each note seems to be operating on the entire canvas of the soundstage at all times, whereas NOS allows for true silence between notes - This technique delineates the position of the notes through the intervals of silence interspersed between them. This is one of the specials "ingredients" of what constitutes its natural sound.

+ Punchy, Powerful Tuning
The sheer density of the notes, because the origin of each note is spatially focused, packs a serious punch when expressed. All the energy of the note spews forth toward you from one single point, propelling the sound forward with great pressure. The result is a great mid-bass punch, hyper-saturated midrange (without the shout) and an exquisitely thick and rich treble.
- Somewhat Limited Stereo Separation
For those familiar with DACS that house a single chip as opposed to multiple chips, one of more for each channel, you may agree with me that single chip solutions can sound overly focused in the middle by comparison. They seem to invariably offer a sound that is closer to mono. I believe I sense this phenomenon with the HIBY Fc6 where technically, it the stereo separation is not quite up there with the best performers. Depending on who you ask, this may not even be a con because it does mean the sound is a little more cohesive even though the notes themselves are more firmly anchored to the middle of the stage.
- Somewhat Limited Macro-Dynamics
FC6 gives out roughly 100mW into 32Ohms which sounds decent, and it is, but when compared to more powerful dongles such as the xDuoo Link2Bal Max which musters 200mW into 32Ohms (single ended) you can definitely hear how the macro-dynamics scale up significantly. The Link2Bal Max manages to sound more grand, expanded and more controlled when pushing the volume. It cannot touch the Fc6 in terms of microdynamics however, sounding much less vibrant and expressive when rendering the smallest nuances.


Conclusion:
HIBY FC6 emerges as a remarkable piece of audio engineering, offering a tantalizing glimpse into the realm of high-fidelity sound reproduction. With its NOS mode, it delivers an authentic audio experience, untouched by the constraints of digital processing, allowing each note to bloom with richness and depth. The FC6's ability to infuse density into every note, coupled with its polished treble and expressive micro-dynamics, creates a truly immersive listening journey where music just sounds so self-evidently natural. While it may exhibit minor limitations in stereo separation and macro-dynamics compared to its peers, these are well and truly overshadowed by its ability to unveil the true essence of the music, making the HIBY FC6 a compelling choice for audiophiles seeking unparalleled sonic fidelity and musical enjoyment without going into mega-bucks territory. A must have piece of equipment.

New Head-Fier
The Sleeping Panda
Pros: + Wakes Up And Transforms When Fed Power
+ Timbre Somewhere between DD & Planar
+ Linearly Resolving Treble
+ Non-Shouty Yet Clear Upper Mids
+ Straight Glide From Bass To Mids
+ Wide & Tall Soundstage
Cons: - Wakes Up And Transforms When Fed Power
- Somewhat Exaggerated Stereo Separation
- Somewhat Flat Depth Gradation
- Bass Depth
+/- Transforms When Given Power:
This is both a pro and a con. Well, I guess it is more of a con than not. You cannot judge this IEM driven by a dongle off of a phone. This IEM will not fully wake up even if you plug said dongle to your laptop. Sure, it gets loads better, but it is still only halfway of the performance it is capable of. It scales very nicely with more and better power and gear. This is why I refer to it as the Sleeping Panda, because It really wakes up when fed and I suspect many people have only met the Sleeping Panda so it is getting slept on. Give the Panda some Juice!
Most if not all planars benefit from power but the P1 Max I found to be a particularly severe case. Previous Planar experiences include Timeless, Hook-X, HeyDay & S12 Pro. They all sound themselves, more or less, through a dongle as long as fed balanced. P1 Max sounds confused, sloppy, closed in and murky on a phone through a dongle.

+ Timbre Somewhere between DD & Planar:
The tuning of the P1 Max is in my view necessary for a planar to sound enjoyable and this is the saving grace with this Planar - It reminds you of a DD in the onset of transients and bloomy nature of notes. It is as far removed from the other planars in this sense as it is close to most DDs - so I view it as 50% planar and 50% DD.
It is just enough to hide most of the Planar sins such as anemic bass, sharp steely upper mids and treble and that dreaded planar timbre. (Looking at you Timeless!)


+ Linearly Resolving Treble:
It is linear from about 3kHz to 8kHz in a gently downsloping fashion and I believe this explains why the treble is so present yet well-behaved. Granted, when driven with some power and preferably a smoother than neutral source. Hey, this is still a planar after all. I believe JAYY from Jays Audio on Youtube said in his review that the P1 Max delivers his favourite treble performance under $500 and I can certainly sympathize with that statement. The treble performance here is stellar (especially so for the money which I will remind you, is $84 during sales!) as long as you take some care in meeting its power requirement, using narrow bore tips and a smoother than neutral source. The only negative thing I would like to note is the 9kHz peak isn't probably all due to measurement artifact, so reducing it by 2-3dB might be wise here.

+ Non-Shouty Yet Clear Upper Mids:
As shown above, the upper mids are on the more gentle side of things which means you can crank the Panda more than other planars.
It is a lower contrast sound than the other planars but because it is a planar, it still retains clarity. What the Panda is not is shrill, but it is full-sounding and powerful. Some may find it is lacking some energy at 3-4kHz to fully do female vocals justice, but it keeps it from becoming fatiquing or overly crunchy.


+ Straight Glide From Bass To Mids:
This allows for the listener to percieve more "meat" of the music across the mid-bass and midrange. The P1 Max sounds satisfyingly full and filled-in compared to Timeless and Hook-X. It also works, I would imagine, to mask planar timbre and thinness. Planar IEMs in my opinion has to have generous bass and lower mids in order to not sound overly tightened and reveal the inherent planar timbre. The stock tuning of elevation in the lower mids and mid-bass seems to be an inherent quality so it is possible to EQ in some sub-bass.

+ Wide & Tall Soundstage:
I'm happy to report the soundstage not being completely panorama in shape, but having very decent height and perfectly adequate horizontal width to boot.
The crucial thing to avoid here is the sensation of "sonic walls" which is when you can tell where the sounds stop right at the level of your ears and refuse to go beyond your skull. IEMs playing in your ears as opposed to filling a virtual room where sounds can jump in and out of would-be barriers. In other words, there is a pleasureable psychoacoustic effect at play here keeping the music spacious and not closed-in.

- Somewhat Exaggerated Stereo Separation
This is more of a nitpick, but someone pointed it out in another review of the P1 Max. There is a slight exaggeration of the stereo separation where for example vocals have difficulty forming a phantom center which is when two speakers create the illusion of a speaker in the middle of them. The sounds seem to be magnetized somewhat to either L & R earpiece. In other words, I would like some more cohesiveness and mono presentation of the sound. (Less obvious when using 3.5mm single ended outputs, but then the stage size suffers)

- Somewhat Flat Depth Gradation:
This is the usual drawbacks of planars, a difficulty of portraying depth in the headstage. P1 Max is not the worst offender I have heard (again looking at you Timeless!)
but still, it is something planars always struggle with and here it is no different.

- Bass Depth:
As I touched on earlier, the sub-bass can be EQd in. The stock tuning can afford it so to speak. If you want a super-contrasty, dynamic planar experience, I believe the Letshouer S12 Pro is the choice. P1 Max is polite in every way you can imagine, which is why I like it so much. It is just well-judged and pleasant, even if it doens't bring the most excitement. The fact that it is the cheapest of the more well-known planar IEMs is a cherry on-top.

Conclusion:
The P1 Max is a sleeper. It is also very slept-on. Give it some power and it will transform into an IEM that has no earthly right costing $84. The launch price of $169 is a harder pill to swallow, but honestly, I would still pick P1 Max above the other planars in the line-up due to the quite awful timbre of its competitors.
It will be interesting how the new P1 Max 2 will improve upon this, given that they are said to have the same tuning and same driver specifications.

New Head-Fier
The Note Decay Reference at $200
Pros: Wide Open Headstage
Bone Conduction Adding Audible Tactility In Bass And Mids
Outstandingly Natural Timbre
Note Reverberation
Higher Notes Of Vocals
Midrange Transparency
All-Encompassing Bass Presence
Cons: Bright-Tilted Tone
Diffuse Imaging
Non-Articulate Treble
Needs A Nozzle Filter To Achieve Tone Balance & Bring Treble Peaks Down
+Wide Open Headstage:
Since the Wind is open-backed, notes can decay naturally and infinitely without a sense of hitting and bouncing off the backplate. This adds to the timbre decay which ends up being so natural that you've never heard it. It has a circular headstage where it is as tall as it is wide, and it is very wide with quite good depth.
What is more, it is incredibly open-sounding where you can't sense an obvious end to the stage, beating out even full-sized headphones such as HD650 or Hifiman Ananda in terms of how notes decay outwards. At the same time, it is very intimate where voices come really close to you, singing exclusively for you, the listener.

+Bone Conduction Adding Audible Tactility In Bass And Mids:
Yeppers, this bone conducation works wonders. If you place your thumbs on the surface of where the bone conduction operates throught he shell, you can actually legitimately feel the vibration. How this is expressed during musical replay during actual listening is like it's adding a subtle layer on the replay that is perfectly synced to the dynamic driver, humming along nicely with what is happening in the bass and mids. It makes everything in the bass and mids a little denser, more physical, more tactile.

+Outstandingly Natural Timbre:
As mentioned before, timbre is outstanding. Each note has proper weight thanks to the BC driver and the open-backed nature allows for uninhibited infinite ripple decay of the notes.
What you end up with are notes that you experience like this in your head:

+Reverberation:
The BC driver together with the open-back infuses each note with a reverb that also aids the sensation of the note expanding forever until it naturally dissipates, like a drop in water.

+Higher Notes Of Vocals:
The high notes of vocals or instruments is one of BQEYZ specialties. There is a delicious vibrancy there around 2-3kHz that makes the crystalline aspect of voices really shine through and touch you. Singers who are belting out sound super dynamic and punch through all the way to your dopamine system. Female vocals operate in these frequencies more often than male vocals, so they benefit more.

+Midrange Transparency:
Really great transparency in the mid-range. It sounds very dynamic, powerful, transparent, pure. This allows you to connect to the performance and hear the music in layers.

+All-Encompassing Bass Presence:
A huge bass presence thanks to the BC driver vibrating. It's huge not in terms of depth or volume, although the Wind is no slouch in those areas, but rather; it's huge in sheer size. It fills the entire headstage with bass. It's like your head is inside the guitar while it's strumming along. This calls for powerful sources that tighten up the bass while adding a little extension ontop for best synergy. The Wind is all about being inside each note as opposed to standing at a distance and seeing the separation between each note.


-Bright-Tilted Tone:
Now for the negatives and the first one is a nitpick. The Wind has, despite its great BC driver adding substance to the bass and mids, a slight bright tilt to its tonal balance.
The LCP dynamic driver is maximized for upper-midrange purity, but becomes lean in the lower mids in the pursuit of transparency. The BC driver does fill
in the sound to a good degree, but doesn't quite compensate all the way to say it has a perfect tonal balance.

-Diffuse Imaging:
The notes are so large, because they are not contained by treble contours. This makes the imaging diffuse and unspecified, so this is not a set
for analyzing exactly how the mix has been mastered and put together. Rather, you enjoy the very center of the note first, spewing forth to the forefront.

-Non-Articulate Treble:
One of the most immediate things you notice about the Wind is its absence of treble. What I mean is, it gives such a close inspection of each note that you could say you're inside of it and you lose the perspective of the contour of each note. This hurts the sense of sensing separation and location of the treble. You hear treble, but your mind can't pin point where "on the instrument" it is.


-Needs A Nozzle Filter To Achieve Tone Balance & Bring Treble Peaks Down:
I rectify the bright tonal balance by adding a nozzle filter which tames the peaks in the treble, giving it a perceived warmer and more refined sound. After doing this, it becomes almost perfect according to my preferences. By adding the filter, you effectively negate the first negative point about having a bright-tilted tone.

Conclusion:
The Wind is a special IEM that sounds like no other IEM that I have heard. It delivers a unique and addictive perspective to music that is only enabled by its BC driver and open-back nature. I consider it the best IEM under $500 and it is one of my favourite IEMS ever, all things considered. At $200, it is a must have for anyone, either as your main set or as a reference in terms of natural note decay.
