Review Final Sonorous III: Exquisite performer
Pros: Beautiful tonality, perfectly balanced, natural and extremely realistic; very well controlled bass, mellow mids and extended tremble; huge soundstage, spatial image, great dynamics and separation; unsurpassed quality.
Cons: A bit on the heavy side on paper, although I never really felt it.
Introduction

Final is a company that needs no introduction. It has a long history in the audio industry, and in the past several years it specializes in the design and manufacture of IEMs and headphones. I have reviewed some Final IEMs, ranging from the very modestly priced E2000C/E3000C to the Company’s flagship (and very expensive) A8000. Obviously, all these IEMs do not have the same performance. A8000 has a stellar performance in terms of balance, transparency, natural presentation and almost zero distortion; it is among the very best IEMs on the planet today, and it is my personal reference set. On the other hand, even very reasonably priced Final IEMs, like E2000/E3000, have a lot of the merits of their (much higher priced) siblings, like A8000. These merits are summarized to want I call “Final tonality”, which for me is unique, and I dare to say that I have not found in almost all other IEMs that I have tried.

However, Final also makes headphones! Currently, they are making the D series, the Sonorous series and the wireless UX series. Originally, the Sonorous series included many models, from the flagship (and really highly priced) Sonorous X and VIII to the rather modestly priced Sonorous III and II. Recently, Final decided to discontinue all Sonorous models except for the III and II, keeping as their flagship headphones the D8000, which however use a planar magnetic driver, so it is a whole different design.

I recently got a sample of Sonorous III, and I was very much interested to see how good they sound given that their MSRP is $399.00 and sometimes go on sale for as low as $299.00, so certainly they won't break your bank!


Description

Sonorous is a whole series originally including six different models, II, III, IV, VI, VIII and X. Now, it is quite interesting that II, III, VIII and X are single dynamic driver models, while IV and VI are hybrid, adding to the dynamic driver a balance armature one.

The first thing that I have to point out is that the flagship Sonorous X shares quite a bit with Sonorous III. As much as this might sound crazy and before you blame me that I am highly exaggerating, please allow me to mention a few things that may convince you for the truthfulness of my statement. First of all, if you put Sonorous X and III side by side, you will realize that they have the same type of exterior housing; just look at the above pictures! Of course, the ear cups of the X are made of highly polished stainless steel and aluminum, while for the III it was used textured ABS of excellent quality; please let me also mention that the whole of the Sonorous series is manufactured in the premises of Final in Japan. So, although the III may be considered the “poor man’s” X, it nonetheless looks really nice.

Sonorous III housing.jpg


Even more interesting is that Sonorous X and III share the same driver philosophy: A 50mm dynamic driver, with the driver unit integrated with the front plate. This design, according to Final, reduces the instabilities, such as resonance and deflection, that adversely affect sound quality and at the same time enhance clarity. Now, on the X, the driver unit and the front plate are machined as an integrated unit from the same piece of aluminum magnesium alloy, while on the III the front plate is moulded from a hard resin that is comprised of hard polycarbonate strengthened with 30% glass added to it. It is also remarkable that both the X and the III sport the same titanium diaphragm.

Another common feature that both the Sonorous X and III share is the BAM (Balancing Air Movement) mechanism. This was originally developed for balanced armature drivers, and it is the first time that it has been employed on a dynamic driver. The idea of the BAM system is to optimize the air pressure on the front and the back of the diaphragm, and the result is the accurate reproduction of bass tones and the three-dimensional spatial representation. On top of that, Final applied on III even more precise tuning based on knowledge obtained through the development of X.

Moreover, both Sonorous X and III employ a 3.5mm metal plated monaural termination plugs, which takes care of poor connection through changes over time. Furthermore, on the headphone end the plugs are terminated with a locking mechanism that rotates 90 degrees, which is a Final’s proprietary system.

Last but not least, Final knows that the ear pads used in headphones play an important role in sound quality; the reason is very simple: The low frequency varies with the space between the ear pad and the ear. In order to achieve optimal sound quality and superior fit, Final employed synthetic leather, which is equally flexible both horizontally and vertically, and has carefully chosen the sponge padding materials which, with the right apertures on the interior and exterior of the pads, ensure clear sound quality with sealed headphones. It is really impressive that Final developed different set of pads for different Sonorous models, while particular attention was given into the pads used in Sonorous III.

Attention to every little detail might be unusual or even considered peculiarity for some companies, but it is the trend for and should therefore be expected from Final! The question is how all this meticulous design translates into sound quality; let’s find out!


The sound

I hope it became clear that Sonorous III shares a number of common features with the flagship Sonorous X, so it is natural to expect, and it is actually no wonder, that the two share quite a bit in their sound signature. Although I do believe that this is a true statement, I cannot confirm it, simply because I did not have a chance to listen to the X. On the other hand, I am also pretty sure that the X is a true and clear upgrade of the III; otherwise, how could one justify an “upgrade” in the price of III by 12x?

Nonetheless, I shall go ahead and say it upfront: The sound signature of Sonorous III is simply exquisite, far beyond of what one would expect from a set costing $299.00-$399.00. It is balanced, yet natural and realistic; so, it is not sterile, and certainly not neutral, a term that many people like to use. As I have mentioned in previous reviews, to me there is no real neutrality in a sound signature; the main reason for this is that the tuning of a headphone or an IEM is made by a real person, who no matter how much tries to keep his personal preference out of the tuning, it is really impossible to do it 100%.

So, Sonorous III has the beautiful, and unique I should say, Final tonality that characterizes every headphone or IEM made by the Company. It has a really relaxed sound with precisely the correct amount of bass, mids and tremble, and it invites you to listen more and more to it.

The bass is balanced between sub- and mid-bass, and if you ask me which one is prevailing, I would have a hard time to tell you; in some musical pieces I thought that it is the sub-bass and in others I thought it is the mid-bass; so, Sonorous III is a chameleon that can change according to the song, which I do like. Nonetheless, in all cases, whether sub- or mid-bass, it is full, polite, tight and extremely well controlled.

The mids are never forward or recessed, and both female and male vocals are presented beautifully, with a sense of naturalness and realism.

The tremble is very extended, so the sound is crisp and very detailed without any hint of roll of; however, it is never harsh and, no matter for how long you listen to, you never get the impression of fatigueness.

The soundstage is huge, in height, width and depth, while the image is spatial and holographic; you feel that the sound is all around you and fills the room and beyond. The separation and dynamics are excellent, while Sonorous III is really an easy load.

I tried Sonorous III on a big variety of songs like “The Look Of Love” by Diana Krall, from the album with the same name, Verve, or “You Don’t Have To Say You Love Me” by Jack Savoretti, Lanza Music Limited, and in all of them all female and male vocals were beautifully presented. I also played through the III many jazz pieces by Vince Guaraldi, and the performance was nothing short of outstanding. Finally, I tried Sonorous III in “Fanfare For The Volunteer” by Mark O’Connor, from the album with the same name, Sony Classical. This is a beautiful and very demanding orchestral piece with many high and low passages, which is very common in orchestral music, and once again Sonorous III managed to deliver it in a masterful way.

Another interesting thing is that although Sonorous III is on the heavy side, weighting 410g, I never felt any discomfort, at least not up to 2-3 hours that I was wearing it; you certainly feel that it is on your head, but it does not tend to press you and thus lead you to remove it.

Now, as I already mentioned, Final, having realized the importance of ear pads, provides in its Sonorous series five types, A-E; my Sonorous III came with the D-type, and it is quite interesting that also appropriate for it is B-, C- and E-type pads; I don’t have them, but I promise to ask Final for them and update my review.


Selected comparison

I compared Sonorous III to Sennheiser HD599, one of Sennheiser’s popular models. Both headphones have similar sensitivity, although the Sonorous III is an easier load, 16Ω versus 50Ω for the HD599 (which is also a fairly easy load).

The HD599 is cheaper, costing $199.95. It has a balanced sound signature, but clearly on the warm side, which is probably the reason for its popularity. It lacks the transparency and resolution of Sonorous III and, up to a point, its holographic image. The dynamics and separation is about the same in both sets. I guess one has, up to a certain extent, to sacrifice some of the resolution and transparency for the warm sound signature; this is not necessarily bad, but rather a matter of choice, and it is also something that many people do prefer.

Overall, the Sonorous III is, for my taste, superior to HD599. Of course, one could say that the III is $100.00 more expensive; personally, I wouldn’t mind paying $100.00 if I would enjoy the level of performance that Sonorous III has to offer.


Conclusion

I know that $299.00-$399.00 that Sonorous III costs is not little money. However, I dare to say that for what it does is a true bargain. It has the great Final tonality, so it is beautifully balanced, yet natural and with a sense of realism that you rarely meet at this price level. It has an articulate and well controlled bass, mellow mids and extended tremble. It also has a huge soundstage, spatial image and great dynamics and separation. And on top of all this, its quality is unsurpassed.

I am pretty sure that Sonorous III performance is very close to that of Sonorous X for just a fraction of the cost, while you would have to pay substantially more if you wanted to go to the next level. Personally, I am most satisfied with what Sonorous III can do, and I could not be more enthusiastic about it.

Good review, and I love the Sonorous III. The only closed-back with better staging among the ones I've heard is the Sennheiser HD820 and that tells a lot.

Great headphone for the money. A bit dry sounding and lacking in soundstage depth but again for the money it was hard to beat. Nighthawk were the opposite spectrum.

Sonorous III is truly underrated; I had not realized that before the review. Final used a lot of the experience they got from the development of Sonorous VIII and X; so, I am sure that the X and III will appear to be "cut from the same fabric", although they have different sound signatures. Another thing is that the signature changes with the pads; I have the Pandora Hope VI, which has the A-type pads (it has an amazing performance, although it is a different, hybrid, concept); I am trying to get the B-, C- and E-types in order to update my review.

Arguably by far the best closedbacks below $500
Pros: Beyond spectacular 3D soundstage (for closedback HP) and imaging.
Two alternative, equally enjoyable timbres and tonalities.
Sonorus-III great on natural, relaxed, microdynamic delivery.
Sonorous-II special for clear, acoustic, vivid notes.
Further tuning adjustement possible via pad rolling.
Good comfort.
Very easy to drive.
Superb construction and general quality at a not huge price. Great value.
Cons: Not recommended for unseated listening.
Neither good for “bass-heads” and/or distorted electronics lovers, etc.
Not a lot of third party accessories available for the mod inclined
Some sound leak, not recommended in a library or such
I’ve been adopting and enjoying final Sonorus-II and Sonorous-III as my preferred closedback mid-tier (€300-ish) headphones for a while now, but other stuff kept me from dedicating enough time to report my views on a article.

Now that these babies have been stuck on our Wall of Excellence though… well, it’s time to act.


Test setup​

Sources: Apogee Groove + Burson FUN + IEMatch / Apogee Groove / Sony NW-A55 mrWalkman / Questyle QP1R – Type-D pads on Sonorous-II, Type-E pads on Sonorous-III – Stock OFC cable – lossless 16-24/44.1-192 FLAC tracks.

Signature analysis​

Tonality Both models offer and evidently acoustic, organic timbre.
Sonorous-II more inclined to the clean&lean side, with edgier tones on all sections of the spectrum while Sonorous-III keener to softer transients, offering a more bodied while at the same time less aggressive sound. Both may be defined “organic”, just two different flavours.
Sonorous-II tonality is bright-neutral, Sonorous-III play on more balanced tones, warmer than their siblings but only slightly warm in absolute terms, and with a definite centric accent.

Sub-Bass Sub bass is fully extended down low on both models. Rumble is properly delivered, keeping its foundation role.

Mid Bass Sonorous-II midbass is snappy on attack and fast on decays, tonically fit like an athlete. Modest in elevation, it never veils anywhere. Just a whiff more of decay would furtherly increase texturing.
Sonorous-III are evidently more generous on mid-bass which comes out in a sense “gentler”, more textured and articulated, but also less incisive and “punchy”. Sonorous-III mid-bass is more athmospheric, and while both models do offer the same soundstage size on critical listening, the gut-feeling is that Sonorous-III‘s ambience is more extended due to such softer midbass tones.

Mids Mids are possibly where the two models differ the most.
Sonorous-II keep mids I would say in line with the midbass, and gives them a clear, full, rounded, enucleated, defined almost edgy character, all the way from low mids to high mids.
Sonorous-III bring them more to the front of the scene, while at the same time removing some of their note solidity, swapping it for more slightly but evidently more relaxed transients resulting in a softer, warmer tone and a less technical if you wish but possibly more organic timbre.
As mentioned above Sonorous-III push midbass higher than Sonorous-II but the same happens on lowmids which is why the latter never sound recessed compared to the midbass, the other way around sometimes which is personally, if one, the sole single part I’m not deeply fond of regarding both of these phones.

Male Vocals Male voices on Sonorous-II are clear, neutral, detailed and articulated. Sonorous-III makes them evidently warmer a more accented; compared to Sonorous-II you lose a tad of contour precision, but get a higher organicity sensation in return.

Female Vocals Sonorous-II delivers clear, loud, sparkly female voices. Sonorous-III makes them a good 10% softer and less “vivid”, more polished, slightly warmer and somewhat more nuanced.

Highs Taken per-se, trebles are equally elevated and extended on both Sonorous-II and Sonorous-III. The difference lies in note weight and air.
Sonorous-II offer edgier notes, which are nevertheless also very well bodied at all times, granting absense of shrills or zings, or excessive thinness on microdetails.
Sonorous-III deliver less edgy, more polished notes on trebles like it does all over the presentation. Hence, treble notes come accross as thinner on Sonorous-III, thereby on one hand more structurally inclined to render cymbals micro-sparkles, and on the other hand less authoritative, more blended in the overall more relaxing Sonorous-III presentation compared to the more energetic experience delivered by Sonorous-II

Technicalities​

Soundstage Very exteneded in width, which becomes extremely extended if we consider we are talking about a closedback, and incredibly extended in terms of height and depth. Sonorous-II and Sonorous-III deliver a quite holographic stage scene. According to final this is one of the direct results of their BAM technology (see below), and it’s probably the best, or second best aspect of these headphones.

Imaging Sonorous-II and Sonorous-III imaging is nothing short of spectacular, result of driver precision and presentation clarity

Details Detail retrieval is better from highmids and trebles and more limited from the bass on both models. That being said, as mentioned above Sonorous-II deliver edgier, snappier and more solid (bodied) notes and come therefore accross cleaner than Sonorous-III when it comes to macro-details, and less subtle, less micro-dynamic than Sonorous-III when it comes to the tinyer details.

Instrument separation Layering is very good on both models, but Sonorous-II in this case comes out quite evidently better in the direct comparison. Sonorous-III‘s excersice of mids-centricity results in occasional layering deficiency on some tracks, in conjunction with particularly fast and busy passages.

Driveability Both Sonorous-II and Sonorous-III share the exact same electrical requirements resulting in extremely easy driveability – a mere phone is enough powerwise. Needless to say, considering the drivers’ sophystication pairing a seriously good DAC upstream is strongly recommended. Also, depending on personal taste pairing Sonorous-II with a warm amp may offer an interesting presentation variation to explore. For similar reason, pairing Sonorous-III with a highly resolving source will too.

Physicals​

Build The two models are identical. Housings are made of sturdy ABS, with some 30% glass mixed-in. Physical resilience apart, the material choice is according to final crucial to keeping resonances under control. Pads are moderately soft, and their toroidal structure subtends a sheet of filter material. The hedband is made of steel, well padded and covered with the same faux leather as the pads. Housings are mounted onto the headband terminals with a sliding & 3d-swiveling mechanism which is at the same time apparently reliable, smooth to operate and very silent during normal head movements.

Fit Sonorous-II and Sonorous-III pads properly embrace my outer ear (my pinnas are not small but not huge either, ymmv of course). Final makes a series of alternative earpads available which contribute to modify the tuning quite a bit, read below for a separate analysis. For the record my preference on Sonorous-II is Type-D, on Sonorous-III is Type-E, and as indicated above these are the pads I used for this review (and I use daily for my listenings)

Comfort 410g are definitely on the border of comfort at least for my tastes, and anyhow I would never recommend wearing Sonorous-II or Sonorous-III while running or such. That said, I do find them more than bearable for even long-ish sessions even when I’m not relaxing on the armchair but just sitting at my desk. Within the boundaries of what is reasonable to expect by closebacks, they are also not nasty at all in terms of heating.

Isolation Isolation is good but not “perfect”, some sound does leak both ways, and especially in the outer way. In practical terms, don’t expect your partner not to complain if you listen in bed, or others not to kick you out of a serious library…

Cable Sonorous-II and Sonorous-III both come bundled with the same OFC cable. Build quality is apparently top notch, it’s nigh-impossibly to make it tangle, produces zero microphonics and the sheath has a wonderfully smooth, satin finish. The 3.5mm connectors plugging into the drivers feature a brilliant “twist&lock” mechanism. It’s apparently not easy to find third party alternative / upgrade cables on the market, and – be warned – final-brand ones are pretty expensive.

A glance at the technology​


Quite a few by now know final (yes, they write it lowercase) as a group of incredibly proficient audio engineers, and their products, may them encounter the complete appreciation of the single individual or not, based on personal taste, are anyhow always granted to be the fruit of non-trivial investigations, studies and technological achievements. Sonorous headphones make of course no exception.

Ear pads​

Ear pads – their internal structure, size, thickness, and external fabric – do change earphones sound even more than what eartips do to IEMs.

First and foremost, the distance between the actual sound transducers and the ear modulate low frequency sound pressure, which obviously significantly influences the presentation. Based on this fact, final Sonorous earpads are filled with sponges of different thickness and consistency. Their external material is synthetic leather featuring equal horizontal and vertical flexibility. Finally,

Another important aspect when it comes to closed-back earphones is avoiding sound appearing “muffled” due to lack of backside venting. Final accomodates for this by carving small apertures on the inside and the outside of the pads “donuts”, achieving superb results in terms of sound clarity.

Lastly, final designed a quite ingenious system to facilitate pad swapping. By direct experience it does work. You may want to take a look at this video to get an idea.

BAM​

That stands for “Balancin Air Movement”. It’s the marketing name for final’s project focused on obtaining results similar to open-back heaphones even on closed-back ones, especially in terms of clarity, controlled bass delivery and of course soundstage and imaging.

At final, we decided to focus on developing technology for the reproduction of bass tones and three-dimensional space with the full-range reproduction of a theoretically unproblematic single driver unit, rather than taking things in a multiway direction. We went back to the beginning and reviewed the performance of the balanced armature driver, focusing our attention on something we had previously overlooked : airflow inside the housing. We developed BAM (Balancing Air Movement), a mechanism that optimizes airflow inside the housing through the creation of an aperture in the driver unit, which is usually sealed. While achieving bass tones and deep, three-dimensional spatial representation, which proved difficult with single driver full-range reproduction, we achieved a BA type that at the same time made for natural listening the user doesn’t tire of.

And boy, that works! Of course I’m not technically competent enough to say wether the trick is that or “just” that, but it’s a fact that Sonorous earphones do deliver an incredibly clear and vast soundstage, and perfectly controlled bass, actually sensibly better than any other closedback headphone I happened to audition equal or below their cost. On the other hand, reading final’s description we get a hint as to why Sonorous HPs are “less isolating” than other models in their same technological category.

Let’s pad-roll a bit… !​

Sonorous II and III are good as-is, i.e. with their stock pads. Period. You can skip this chapter, especially if you are on a tight budget.

That said, given my appreciation for the base configuration I wanted to go all the way through on their available options – at least the official ones, those offered by the manufacturer themselves.

Final makes a number of variations available for their Sonorous headphones line, which are all mechanically compatible with every model in the lineup as the housings chassis are identical accross the board. Each model is named with a letter (Type-B, Type-C, etc). Sonorous-II and Sonorous-III come equipped with 2 different earpad variations already, then I ordered 2 more different ones, and I started rolling…

ModelSonorous-II notesSonorous-III notes
Type B
(Sonorous-IV stock)
surface : synthetic leather
sponge : ralatively thin and soft
filter : single layer
Bass is faster than stock (E) and even faster then (C). Mids are similar but highmids get some adrenaline. Trebles stay vivid and sparkly. Overall sensibly brighter compared to stock, might be excessive for some users, and definitely for some genres.Mids are more recessed than stock (D) and furtherly back compared to (C), while still very well defined and detailed. Bass is even faster. Highmids become the star of the show.
Type C
(Sonorous-VIII/X stock)
surface : synthetic leather
sponge : W ring combining two different sponge types
filter : 3 layer
More bodied bass and mids compared to stock (E). More evidently polished / tamed trebles which come accross less sparkly. Definitely more balanced.Darker than stock (C). Mids are recalled from full forward position. Some air is lacking.
Type D
(Sonorous-III stock)
surface : synthetic leather
sponge : thick, strong sponge
filter : 3 layer
Bass is very similar to stock (E). Mids add some body. Trebles get a bit polished. Overall more a “balanced bright” rather than “netural bright” effect. Still very good for jazz and probably overall ever more loveable than stock pads.
*my personal preference*
Obviously midcenteric. Fast-ish bass. Good trebles.
Type E
(Sonorous-II stock)
surface : synthetic leather
sponge : thick, strong sponge
filter : single layer
Neutral-bright. Fast detailed bass. Good mids, not a specialist for vocals. Very nice detailed and quite airy trebles. Love this.Faster bass compared to stock (D), mids pushed a bit back and made faster and more precise, sparklier trebles.
*my personal preference*


So the aftermath is… I could have saved the money for Type C and B, and just swap stock pads between Sonorous-II and Sonorous-III to reach my preferred configuration on both. But how could I have known it without trying?


Conclusions

Sonorous-II and Sonorous-III are arguably the best closeback headphones on the market in their price class, and in my experience it takes tapping at Shure SRH-1540 to have something significantly competitive to talk about.

While they feature two quite different timbres, tonalities and presentations, neither is a real all-rounder musically wise. I’d recommend Sonorous-II blind-eyed for cool acoustic jazz, and any other clear-timbre musical genres, and Sonorus-III to whomever looks for a warm-neutral, midcentric, incredibly dynamic driver for prog rock, song writers, folk or such.

Finally, they are not “inexpensive” in absolute terms – so they might well not be one’s first take at overear headphones – but rest assured that they are not by any means “cheap”, indeed they are actually worth each single penny in their price for the quality, the comfort and the musical proficiency they deliver to their owner.

For great delight, use the III with an all tube amp and upgrade the cable and install the Final B type pads. See hifiplus and 6moons reviews online.

Respectfully disagree with this member's views on Sonorous II. The stock E type and some B and D type pads were used with them and I did not like anything about the sound of the Sonorous II with any of those pads. But the Sonorous III with the B pads with a tube rectified amplifier bring me great joy.

Reviewer at Sound Perfection Reviews
Formerly affiliated with HiFi Headphones
Pros: Looks, overall sound and build quality
Cons: Not the best all rounder
Firstly I would like to thank HiFiHeadphones for the loan unit, as always I will try to write an honest review. These received the usual 50hrs of burn-in, no real differences were noted.
 
Gear Used:
Audio Opus #2 > Sonorous III
 

 
Tech Specs:

 
MSRP: £299
 
Packaging, Build Quality and Accessories:
The packaging is a nice glossy white box with a picture of the Sonorous III on the front, on the back you get info and specs. Also on the back is a exploded view of the headphones, and what technologies are used. Overall an attractive box, once you open it the headphones are held securely by a cardboard insert, and they are easy to remove from the box with minimal space wasted on packaging.
 
Build quality feels excellent like all other Final products, the housing is ABS, the headband is metal, the cable is detachable and very rubbery and flexible. The earpads are soft and everything feels well made. With some care I can’t see any problems with the build quality.
 

 
Accessories are minimal, all you get is a jack adaptor. I would have liked to see at least a soft carry case/bag. These are made to be semi-portable due to the short cable and they are relatively easy to drive so a bag would be useful to protect them in your bag.
 
Comfort and Isolation:
The cups are shallow and also the opening is quite small for circumaural headphones however I do find them comfortable for a couple of hours use. The clamping force isn’t too strong but they do feel secure, they are not the lightest of headphones but the padding on the headband, along with the width make them very comfortable. So no real complaints, only after long 2 hour+ listening sessions do these start to get a little uncomfortable.
 
Isolation is actually quite good, they block out the tapping of my noisy mechanical keyboard easily, and dull traffic noise when out and about. They won’t block out as much as most IEM’s but they are good for out and about use due to minimal leakage and also fairly good isolation.
 

 
Sound:
Split in to the usual categories with a conclusion at the end.
 
Lows: The first thing that springs to mind is full bodied and smooth, the lows just fill the sound with excellent body but without sounding bloated. I would say they do have a boost in the lows, that helps when there is outside noise, but also makes these very fun to listen to. The reverberation from kick drums is felt within the cups, these can move some air but the lows are never overwhelming. Audioslave - Cochise has a very grungy bass line that cuts through the mix on these with great affect.
 
Mids: The mids are pushed slightly behind the lows, so vocals do not cut through the mix quite as clean as with some headphones, but they are still present and have very good positioning within the soundstage. They do fair better with softer music in the mids, it seems to be during more complex passages they get pushed slightly behind the lows. The detail is there, and they do have power, it’s is just a little farther behind in the mix. Vocals don’t suffer from sibilance, neither are they overly warm from the boost in the lows, they sound very smooth and natural, in that sense the mids are very good on these.
 
Highs: The highs are present but lack overall extension, they are there in quantity and prevents these from sounding dark. I like the amount of treble presence these have you can hear all the different cymbal crashes clearly with good separation. They have good detail up top, and are never boring, they just lack effortless extension.
 
Instrument separation is excellent and the soundstage is incredible for closed back headphones. Very impressive width and also depth, they do excel here.
 

 
Conclusion: I find these to be a very easy going headphone to listen to, they have excellent soundstage capabilities and also the timbre is very good. They are not the fastest headphones, which means they fair better with slower and well recorded music. When you feed them a good quality recording they shine giving you a real insight into the layers of the song. They may lack a little extension up top, but this is easy to overlook, the lows are not overwhelming and do not get in the way of overall enjoyment.
 
 As I am sat here writing this conclusion, Radiohead – Sail To The Moon has come on, and the separation, the depth and the overall euphoric sound is really something quite special on these. Technically these may be lacking in some areas, but they do have some special and unique qualities that suit some genres perfectly, making them a real treat to listen to.
 
Sound Perfection Rating: 8/10 (euphoric and very special with the right music)

We just got a second pair of these, got one on a Topping DX5 (full version not the lite) and it's great. Comparing to other closed backs in this price range, I'd never get the Beyerdynamic DT1770 again, or DT17xx which is more of a comparison as it's easy to drive also. This is maybe the first headphones with pleather pads I really like, the Hyperx Cloud Orbit was nice, but the onboard amp/DAC wouldn't get loud enough for most people on pre-volume war recordings. Get one used on Amazon warehouse for 200 beans and you'll feel like you stole it.
