SHORTCUT TO THE CONCLUSION BELOW:
DISCLAIMER
I'm not much of an audiophile, but i can confirm it's a best value product for an audiophile
of my level from a gaming-wise point of view and such budget.
I will be able to position myself as a specialist when I'll have the time to deep into the theory of sound. I'm a scientist, you know
I suppose there is nothing in this world being subjective, only tastes and biological "specials" of given ears which result in tastes also
We should just clear it out, when NOT using an amp, we must get a good_to_go (fully portable) product, which must fit our tastes. Otherwise, we just see the *Russian АЧХ, looking for technical translation* frequency responses in the able_to_hear sound range (i also suppose infra- and ultra-sound may affect health - another question) to detect whether the given headset is near to ideal (good for one's tastes) or not (also good for one's tastes, but rather the mass).


ALSO GUYS, I have a lot of brainz when it comes to study something, I call it "scientist". Your mind is FLEXIBLE (you pay attention to any thought and do not let your emotions overdrive) and always LOOK for the ESSENCE, THEORY (hard to understand bearing in mind we're discussing subjective things like "sound quality" - sibilance/sparkle_treble as example (although I heard sibilance on a low-end product of my friend).
To be clear, I know what it means to be an audiophile, but because of my wallet I could not afford anything that has good bass and/or pleasing&refined treble, now that i've bought this headset, I suppose I can say they are pretty damn good (wasn't really looking for audiophile-capable home headset). It's my first try in overviewing a product, i've tried to be objective as I could, because these humble monsters just make me feel proud for Cyber Snipa, again.
I'm kindly requesting some of the head-fi specialists to do a review, because IMHO it's a good buy.
- not a full/entire specification for the product -

I'm not a native english speaker, sorry.

Impedance | 32O | 32O | 32O | 8O |
Frequency Response | 20~20 KHz | 18~20 KHz | 20~20 KHz | 10~400 Hz** |
Output power | 200 mW | 400 mW | 200 mW | 600mW |

T.H.D | 0.4% | 0.1% | 0.4% | 1% |
Sensitivity (S.P.L) | 108 dB | 100 dB | 108 dB |
*Can be explained be reverb presence. dB simply do not fade away, because _it's_intended_ to have this kind of reverb. May be an issue of taste. I've managed to storch a lot of treble or bass, even both (maybe I just am not such a fun of bass as most of readers) (Ofc, maintaining clarity and without overriding amplifying support indicated by engineers (+12dB)).
**Funny thing is that they allow subwoofer/Center swap, but i noticed only bassy frequencies are "done" by subwoofer from the specification (<400Hz). The 5.1 system is developed only for 5.1, they did not think about audiophiles (dedication of each driver for certain frequencies, say {music_mode}, because 5.1 means soundstage is a priority). They tell us nothing regarding the signal_to_noise_ratio for when you use this SWAP (400hz is kinda limitation). In russian sound theorycrafting this sounds like "study of the frequency response", meaning 100% volume study of the drivers for each of the frequencies, having an "ideal model" and a "result" which is how "noise" is found out deviation of output signal from the ideal (>50dB is an equivalent measurement scale done by formula, not practicing) from the desired result of the frequency. I suppose english sound theorycrafting has issues, because in russian theorycrafting there are much less "tastes" and they are clearly told by practical study of Signal-to-noise-ratio!!
Anyhow 4 dedicated drivers are better than one. If we manage to discuss/develop/optimize the thread's drivers these can really be the ideal headphone ATM (value).
To clarify this "lack of information" the subwoofer should be tested separately, with no other drivers put under current, to understand whether there is signal_to_noise sound quality issue in doing so or there is not. I did swap the drivers, just because I found it easier to adjust, did not search in-depth. Will do.
UPD: Tried, mic issue gets even higher with standart subwoofer/center set. Removing the mic will let me do in-depth testings. I suppose now it's not even the mic problem... I damaged that driver with the "resonance"... I suppose it was just smashing the mic components (I ignored the resonance) which made one of the subwoofer start to produce sibilance in it's true meaning... Solved the issue brilliantly... Swapped them again and killed the volume of subwoofers... These little bastards are dead because of me
The moral is simple: Do not trust ANY (means something he didn't say, but you saw something "strange", this strange may kill your product if you're not testing carefully) seller even if he has good reputation...
I'll supply the post regarding images from RU audiophiles ASAP.
Pros:
-DEDICATED SOUNDCARD IN-BUILT (control panel).
-Highly customizable. An in-built equilazer is not a "WOW", but the driver_volume is AMAZING, because the dedicated subwoofer may be "made" to be louder than the other drivers (their impedance differs).
-Very nice sound, if the software (yes, it has dedicated control software) was adjusted accordingly. It has an in-built equilazer and driver_volume (i mean every of the 8 drivers [4 in each "ear"] can be adjusted as you wish)
-Regarding customization. You can SWAP the subwoofer with the central driver.
-Who am I to judge, but I suppose these little humble headset will beat the sh** out any 100$ over-ears regarding soundstage... It's brilliant if up to me.
-Customization. You can switch between gaming and music bass "style". It's called bass enhancement, but i know it lowers audiophile satisfaction and they SAID it.
-8 Drivers, 5.1 system. In-game experience including sound source localization is brilliant. I wish to say i've never heard such precise frequency contrast (my own adjustments in their soundcard).
-Great microphone as far as i know. A weak pro, but you rather wish your microphone to be in-built, as a gamer.
-Also
-Cloth earpads, very nice and comfortable, although the comfort is not perfect, but i cannot say it creates discomfort. See cons section.
-I would say the bass isn't really punchy. (Happened to listen my friends "ears" - I felt like being attacked with pillows onto my ears) It's mild and extremely pleasure-delivering, for me.
-FOR THE SECOND TIME IN MY LIVE tears appeared on my eyes because of SUCH experience... There is everything for me! I adjusted both bass and treble to make me ***.
-IT FKIN VIBRATES (bass drivers). Cannot say it's good or bad, but when it comes to an in-game explosion you may piss your pants


-IMHO, the enginners from Cyber Snipa did a great job from every perspective, the sound is clear, the bass is powerful, punchy (ordinary dubstep audiophile) and rock music audiophile pleasure is also possible. Adjusting their software equilazer i got audiophile pleasure from both genres.
-The build is very great as far as i know. Very sturdy, good engineering thought and good, but hard-to-achieve comfort. See cons section.
-The value is pretty damn good. Can be got for 37EUR plus shipment from computeruniverse.net
(their products are not unique, Prestigio is under the same lead, I suppose, and one more brand, I cannot say which, but i have this info from another buys - PMSG1 Prestigio gaming mouse, which is a copy of Cyber Snipa Silencer - a best buy in gaming-mices with any budget(!!) and Prestigio P5580C MultiTab - a best value tablet for me (satisfies my spec needs entirely, not taking in count TN matrix))
I suppose that's all with the pros.
Cons:
-Pretty heavy, but I cannot say it creates discomfort.
-No isolation
-^regarding^:comfort isssue - the earpads have their pressure point onto the upper part of the skull (meaning that it does not perform uniform pressure onto the whole skull around the ear), it may create some discomfort if not adjusted correctly. Also their new, so it's possible that the earpads-pressure will be lower after a time. If there is any possible mod to fix that - please let me know.
-Damn long cable, but it's nice i can move 2 meters from my PC to do something without taking them off.
-Heavy in-built control panel, if not put on the lap or clipped onto clothes giver slight discomfort from the earpad.
-Lights on the control panel are just too bright. I dunno why they did that, lol. Not a problem, unless some1 susceptible is near. (true regarding to isolation also) I prefer disabling them with black duct tape

-A weak con for me. Maybe a guarantee issue, i'll just have too much trouble solving the guarantee. Don't wish to lose the headset for X amount of time because of such a minor issue. Issue is: One of the "ears" (the one with mic, I suppose that's the problem) is resonating at certain "bassy" frequencies.
Maybe it's a limitation of the headset, because the earpad resonating has mic attached to it. Plastic or the drivers itself may resonate, should look for a fix.
The point is that i'm listening music either on low volume (for some of you it may seem as high volume, lol) and when i wish to get FKIN EXCITED I listen the music SO LOUD I can barely notice this "resonating sound".
-Also a weak con. Maybe a comfort compliance, dunno not a pro. It vibrates if bass-heavy songs are being played at high volume. Can't know if that's ok regarding high-end headphones. Some of you may consider this a con. Can it be fixed by myself? (I know i'll break the warranty) An audiophile friend of mine told me this vibration is artificial: either there is a vibration-driver inside or vibration is caused because the drivers are localized too near to eachother (small earcups for such big drivers)
-Another weak con for me. It seems the engineers consider their customers to be either big-headed or extraterestrials


Conclusion?
As a gamer (with such a head 
1. Unability to turn off the vibration (either it's a dedicated soundcard "Special" for gaming OR it's simply ok even for high-end basshead headphones - can't know).
2. Not for bassheads, when you get OK bass on full (safe for the drivers) volume, it resonates... It's a build issue, because the resonance is a build limitation I suppose (yeah, it's in the driver with the mic). Either we develop a FIX and OMG ITS A PERFECT NON-MOBILE HEADPHONE or we make any of 5.1 headset maker to try and create a model or two of OMG 5.1 AUDIOPHILE HEADPHONE (in-built soundcard needed(!)).
3. No isolation means either you like the volume or you can hear your mommy using the vacuum cleaner 4 meters of you through the doors (one closed

Pros?
You heard the pros

Non-portable overall
Accessories (10/10) - taking in count soundcard and software are "accesories".Build (7/10) - good overall quality, but this resonating sound just pissess me off
Isolation (2/10) - Only warmth for winter

Comfort (7/10) - not for smallheads, also hard to fit it right onto my normal size ears, VIBRATION IS OK?
Sound (6/10) - fully adjustable 'cause of the soundcard, just the build issue destroys it... I suppose
there is nothing like "signature", we just do not know theorycrafting in the whole.
If you do not believe me by word, being a specialist, take the very_high_end 32 ohm
2-driver headphone and try listening FLAC 5.1 using 5.1 emulation, afterwards take
my 5.1 headphones (or the very_high_end 5.1 capped at the impedances given by my
headset and mod it to use 5.1 AMP) with support of needed current and customizing
(dedicated each_driver soundcard customizing (the each_driver_amplifiyng thing from the pros section). I really hope you will prove me wrong.
I've proven i'm perfectly right at this point with one correction:
Doing so will cap volume lower for a good bass... Can't speak certainly, but I
suppose you lose smth like 1/5 of the loudness at least
(8Ohm 600mW bass is the issue I think)
OR
You should have immense knowledge in this kind of theorycrafting to adjust them
perfectly by yourself... I had no such knowledge back then - killed the woofers...
*****IT'S A MISTAKE TO SWAP WOOFER AND CENTER, Woofer will still do bass,
while forced to do treble, just like the other 3 drivers are "forced" to do bass (5-400Hz
implicit) but have no problem with dat*****
Value (11/10) - Can't find any more for the money even close - (11/10) for me, {10+}1 point to that only because THIS BRAND had the fully-adjustable soundcard! Which makes this headset POSSIBLE_FOR_US (sound overhauled)!
Overall (7,5)
Modding {subjective} PORTABLE OVERALL:
{
The mods should be:
1=>>Lol, we need several portable amplifiers ATM - this market didn't take in count 5.1 audiophile headphones TOO (imagine how to connect 8 drivers instead of 2). SO, we have drivers, which should be PORTED for android at least, afterwards, IF this happens:
1. The easy way, tablets have OTG-connect usually, which is then possible to mod into USB, so we can just plug it in with the drivers lended.
2. The hardcore way: We open up "control panel" audiochip, we investigate which USB connects are for sound and which for power, we develop an alternative source of electricity - any batteries with desired current will do (USB current actually, maybe less), connect&close&seal=>DONE.
2.==>The resonating part:
I'll just open them and take the ******* mic out without changing the earpad's isolation/ "wave_bounce" meaning i will make the mic one identical with the ideal earpad. I just have no money to afford another one, this is my only source of good music, i'm afraid wasting it

[size=22.66666603088379px]CAN YOU IMAGINE SWITCHING BETWEEN SOUNDSTAGE 5.1 MODE AND FULL DEDICATION MODE??[/size]
{I mean we have 4 drivers in each earpad, play with them so the hearable_frequencies will be dedicated for CERTAIN driver in equal part, so the total_hearable_frequencies can be divided in 4 groups: low_to_mid-bass, mid_to_high-bass, mids, treble OR WHICHEVER DEDICATION YOU WILL!!! To do the crosslined we need a fully garage-made headphone. I suppose dedication is where the "clarity of sound" is capped (not taking in count impedance). Yes, I'm speaking about "sound signature" ATM because without dedication the engineers have to play a lot with the driver so it will not "blurr/fuzzy/muddle" the frequencies}
