Disclaimer: I bought the Focal Clears from the local distributor after auditioning them several times with my own music. My first impression was that these were the first headphone I've heard that was as good or better than my previous favorite the Sennheiser HD 800 S. Comparisons will be primarily against the HD 800 S and the HD 600 series that I am very familiar with. Also sorry for the poor photo quality (taken with a smartphone).
Introduction:
Focal may be new to enthusiast level headphones, but they have a long history in the high end speaker market. They also famously merged with the British Naim in 2011 to create one of Europe's largest hi-fi companies. As such they possess significant research and development grunt, so when they turned their eyes on the high end headphone market in 2016 a lot of hobbyists were naturally quite intrigued. There was a lot of hype for the Utopia and Elear back when they were released, but for me both were actually big disappointments. I haven't owned either one, but I did audition them and quickly noticed they just weren't my cup of tea at all. The Elear was otherwise interesting, but the dip in the upper midrange made all vocals sound "off". I suspect it was done to make it sound more forgiving with a lot of contemporary music, but it was just a very odd voicing decision as the midrange is the area to which our ears are the most sensitive to. The Utopia on the other hand didn't really fit my head shape well and the extra weight didn't help either. There just wasn't enough clamp and the headphone would easily start sliding off if I moved my head too much. Not sure if I had a good seal either. I wasn't a big fan of the sound: while technically extremely detailed and fast, it didn't have enough bass for my taste and most importantly there was a fairly severe treble spike that I found annoying with a lot of music. There never was a chance I would buy one though, simply due to the extremely high 4000 euro price. I'd still easily pick the Sennheiser HD 800 S over the Utopia. It's on the same level technically (resolution and clarity) in most regards, loses in some (speed and dynamics in particular) and wins in others (soundstage and imaging). Most importantly it's also less than half the price. It has a brighter/thinner sound, but the treble is less harsh/spiky despite being more emphasized.
What initially got me interested in the Clears were early forum comments that while it was technically inferior to the Utopia it no longer had the Elear upper midrange dip or the Utopia treble spike (both deal breakers for me). Then the InnerFidelity review came out and convinced me to go and audition these despite being disappointed in their predecessors. I didn't really expect anything, but to my complete surprise what I found was my new favorite headphone. Why? Read on.
At 55 ohms and a high sensitivity rating the Clears are exceptionally easy to drive and can reach nice volume levels even from mobile sources like phones and tablets. Just make sure you pair them with a low output impedance source as otherwise the frequency response in the bass range is going to be altered due to the impedance/phase characteristics. A high output impedance is also going to result in a poor damping factor which means poor bass control. These do of course benefit from high quality source electronics, but they are nowhere near as demanding of them as the Sennheiser 300 ohm headphones for example. This is both a good and a bad thing: you won't have to spend a lot to have these sound awesome, but on the other hand they won't scale as much with top of the line sources either.
Presentation:
The Clear ships in very minimalistic black packaging. There's the Focal and Clear logos, a brief "Open-back reference headphones" statement and the technical specifications on the side. Everything is also stated in French, which nicely highlight the fact that these are produced at their local factory similarly to what Sennheiser does with their high end products.
The packaging doesn't draw much attention to itself and has a very understated look. Inside you'll find another black box for the included cables and the carrying case with the headphones inside. The included accessories are very generous. There's a standard 6.3mm and a balanced 4-pin XLR cable plus a short 3.5mm cable for portable use. The cables are a bit stiff, but they are well built and fairly light too. That being said they definitely look and feel like "use at home" items. It's a huge upgrade compared to the original heavy and probably too long cable included with the Utopia though. The only minus I can see is that the 3.5mm cable is made from the same material and it's just not very good for actual portable usage: a thinner, more flexible and lighter cable would have been more optimal.
The included carrying case is another highlight: it feels high quality, fits the headphones perfectly and looks very stylish too. From a value point of view I'd say the included accessories are something that would be quite expensive if bought separately, but on the other hand personally I would have preferred to have the choice if I want to buy them or not. Packing them in does help in creating the impression of a high end product though, so from a marketing point of view it makes good sense to include them. Unfortunately you will have to remove the cables for the headphones to fit in the case, but since they use a standard 3.5mm connectors they are easy and quick to swap around. The standard connectors should help these become a popular target for third party cables.
Build quality, design and ergonomics:
The first thing that strikes you is the build quality. They follow the example set by their predecessors the Elear and Utopia: simply superb and in my experience on a completely different level than high end Audeze or HIFIMAN headphones for example. I would say they are on the same level as Sennheiser HD 800 series, but with a very different design philosophy. There's not a hint of a DIY look anywhere and all of the materials exude high quality. Everything feels very solid, there are no sharp edges anywhere and there's tremendous attention to detail right down to the Focal logo on the cups. The memory foam microfiber pads feel nice and breath very well too. They also work fine glasses.
The Clears with their silver color theme have a quite unique look since most of the time high end headphones tend to favor darker color themes. For a long time I thought I'd prefer if they were black, but I've kind of gotten used to them now. They certainly give look different than most other headphones which is always good for marketing. The cables also match the color scheme which is a added nice touch.
It is however important to emphasize that the Clears are not a very modular design. Time will tell if this proves to be an issue or not. Sure you can change the pads, but the headband doesn't seem to be user replaceable at all. The HD 800 (and 600) series in comparison are completely modular. Almost all parts are user replaceable and Sennheiser's spare part prices aren't usually that high either. What happens if/when the padded Clear headband gets too dirty/old and needs to be replaced? Who knows. Maybe Focal will start selling a headband replacement service via their dealers or something similar. We also don´t know how long the earpads will last in daily use. The price for new ones seems to be around 200 euros so they are very expensive to replace.
These aren't light or small headphones either. At 450 grams these are among the heaviest dynamic driver headphones ever made. For example the Sennheiser flagship weighs just 330 grams. But what actually causes this? In the beginning I thought it´s because they use a lot of aluminium, but those parts are actually quite thin and besides it´s a very lightweight metal anyway. The headband looks heavy, but if you pick the Clears up and move them around you´ll quickly notice where most of weight is coming from: the earcups and their internal driver assemblies.
As you can see it's a very open design. The outside grills are quite thin and there´s a double protection system: first against force/touching via a sturdy metal grill and after that a fine mesh to protect the drivers against small debris/hair. It's a very thought out design as there is no way to accidentally break the drivers by pushing them in and it should be safe for pet households too. Time will tell if the fine mesh is enough to stop debris/hairs from getting in, but I'm pretty sure Focal has tested it extensively.
The unique M-shape dome has a very distinctive look. The drivers are also angled. This isn't what a typical headphone driver looks like. It seems like the driver with its suspension system has quite a lot in common with speaker driver designs. Focal going for a custom driver is no surprise though as they have been manufacturing their own speaker drivers for a very long time already. The diaphragm material is quite unusual too: most headphones use plastic, but here you'll find a magnesium/aluminium alloy.
When you first listen to these headphones you'll quickly notice what I consider to be their main technical innovation: the bass goes very deep for an open design and sounds exceptionally clean, fast and has a great sense of impact. My guess is that this new driver likely moves far more air through high excursion than typical designs do: this kind bass response would otherwise be extremely difficult to achieve in an open design where the air pressure can always escape the enclosure.
Nothing comes without a cost though: looking at the Focal driver picture you can see that it's a pretty large assembly including a hefty magnet. Their frame also looks like it's made of stainless steel for added rigidity. Most of the weight is likely simply due to these two. Using different materials for the enclosure/headband probably wouldn't have (at least) dramatically reduced its weight. The heavy weight is just the price you have to pay for the sonic performance. Would these have been better headphones if they were lighter though? Absolutely and I hope Focal manages to bring the weight down in the inevitable successors and trickle down models. As with all heavy headphones the comfort factor is then of paramount importance. Did they get it right?
When I first got my Clears I actually initially attached two HD 650 headband paddings to the headband. I was so used to the fantastic design philosophy Sennheiser uses with their headbands: there's usually no weight directly on top of your head as that's where hotspots tend to form. Needless to say I was very sceptical as the Clears do the exact opposite: they place most of their weight directly on top of your head. The thing is that it actually works this time due to some ingenious engineering. First of all note how the headband actually gets wider in the middle. The headband shape is also much less curved downwards than usual. These two features together ensures that the top of the head hotspot area is actually significantly larger than on most headbands and the rigid structure helps to spread the weight equally. In other words they basically took a design that is usually something that's not a very good idea and made it work. This coupled with a good amount of clamp ensures that I don't really get any hotspots with these on, which is something I found very surprising as I to be honest expected the complete opposite to happen. That being said these won't disappear on your head though: they just weigh too much for that to happen, but they are remarkably comfortable for their weight. Your mileage may vary though: it all depends on your head shape. As usual always audition before buying.
Another key to the good ergonomics is also in the headband design. At first glance using a lot of aluminium sounds like a horrible choice for engineering a comfortable headphone. Just try riding an aluminium bike compared to more flexible steel one for example. Look closer however and you'll be surprised at how much the cups move/swivel. The headband also flexes in several directions. All this is done with an elaborate suspension mechanism inside the headband. To me it looks and sounds like there are lot of springs involved. The downside is that there is some mechanical creaking/clicking sounds when you swivel the cups, but never when you are actually wearing the headphones. I´ll be keeping a close eye on this though to see if it ever gets any worse. Another minus is that this design probably makes the headband replacements very expensive.
What can I say... Focal have done their homework. This isn't a quick "let's just throw something on the market, our brand name will sell it" cash grab. It's obvious they have invested significant R&D resources into doing this well. In other words they are in this to seriously challenge Sennheiser and others in the long game. Good times to be in this hobby!
Sound quality:
I've now used the Clears for around a month and these have basically replaced my previous favorite HD 800 S as my daily go to headphone. This is already becoming a cliche to say, but these headphones opened my eyes towards placing more value on tonal balance. During my ~decade of following this hobby I had become so used to high end headphones being worse in this regard than the legendary HD 600/650 that I basically started taking these flaws for granted. The most important thing to say about the Clears is that are in my experience the first high end headphone that doesn't suffer from this. The tonal balance is simply the best I've ever heard. They just sound ”right” with no major dips or spikes anywhere in the frequency response. This in combination with the low distortion makes them headphones you can easily turn the volume up with without them almost ever sounding fatiguing or harsh. What they don't do however is making you want to turn up the volume all the time, which is actually a really good thing. It my experience that only happens with headphones with severe tonality issues like the Elear with its upper midrange dip or headphones that roll off the treble too much (= you easily keep increasing the volume to get the vocals or treble to sound right, but they never will). I wouldn't be surprised to see these end up being very popular for pro audio purposes too (and actually Focal did just launch the Clear Professionals; different paint job/accessories, but same sound).
Let's start with the bass. Overall to my ears it has the best bass performance in an open dynamic headphone so far. The measurements on various sites look wonderful and it doesn't disappoint subjectively either. While the bass lacks the absolute extension of the high end planars, it goes very deep and does not roll off much in the sub bass range like most open dynamics do. Slam is great for an open can too. The bass is high in resolution and very clean, although it is not the cleanest or most defined bass I've ever heard in an open headphone. That award still goes to the HD 800 series, but the Clears are not far away either. Is it more enjoyable however than the bass on the HD 800 series? Due to the much better extension and quantity the answer is absolutely and that's what counts. The HD 800 sounds lean and thin in comparison while the Clears sound neutral. The bass is also miles beyond the in comparison muddy mess the HD 600 series outputs.
The bass to midrange transition is well done, but there is some very slight bass bleeding into the midrange. I would not pair these with electronics that emphasize bass through adding harmonic distortion for example. This issue is mitigated by using more neutral sources. Personally I feel the bass quantity is just about optimal as it is enough to make a lot of contemporary genres like electronica sound good without sacrificing more traditional audiophile genres like jazz/classical/vocals.
When it comes to the midrange the first thing I noticed was the fantastic sense of realism and the lack of any hint of sibilance. Vocals often sound so real I've been rediscovering a lot of my favorite vocalists lately. The mids are also more neutral compared to the somewhat recessed mids on the HD 800 series. I'm not sure if it's the more neutral presentation, but here to my ears the Clears also surpass the HD 800 series in midrange clarity and resolution. These headphones get the most important part of the frequency response just right. The measurements do show a small dip in the upper midrange though, but I could not have picked that up if I didn't know about it.
While the bass and midrange forms a coherent whole, the highs can sometimes sound a bit disconnected from the rest. This is probably a deliberate tuning choice to enhance the soundstage. It's actually a bit similar (yet not as drastic) to what Earsonics did with the SM64 IEM. I find this effect quite enjoyable on many records, but sometimes it doesn't work that well. It's a very small issue, but something to keep in mind. I rarely notice it as it doesn't bother me much. That being said the highs, while tonally more balanced compared to the rest of the spectrum than in the HD 800 series, are less smooth than on the HD 800 S. This isn't apparent on all songs, but sometimes you notice it. For example the Clears while generally being less "hey look at this click in this record!" than the HD 800 series, on some songs they can actually highlight this kind of stuff more, especially in some pop music. For example on Taylor Swift's Blank Space there's an odd percussion or distortion effect that sounds downright nasty on the Clears. You can still hear it well on the HD 800 series, but it seems more annoying on the Focals. That being said these are still a much better choice for contemporary music due to the more balanced tonality (vs. HD 800 series treble emphasis with a lack of bass extension). I'd also say that the highs have a higher level of resolution on the HD 800 series and it's not just due to the fact of how emphasized they are. The HD 600 and HD 650 are both smoother in the highs as well so if you are very treble sensitive this may bother you. For me however the treble here is still a very smooth listening experience, on a completely different level than the Beyerdynamic T1 mk2 for example.
When it comes to the soundstage that is quite intimate for an open headphone. I would characterize it as listening to music in a somewhat narrow tunnel while sitting closer to the musicians (vs. back row in a concert on HD 800 series). This is both a good and a bad thing and ultimately there's no right or wrong here. This is the more traditional headphone presentation. Both approaches are enjoyable though and have their own strengths and weaknesses. I find the Clears presentation more emotionally engaging in general, but I do like the speaker like sensation the HD 800 series pulls off too. Imaging within the fairly small soundstage is really sharp though and there is also a good amount of air between the instruments. You quickly get accustomed to the presentation style and after a while you don't really notice it much anymore. Instrument separation is fantastic, much better than on the HD 600 series although still not quite as good as on the HD 800 series.
There's a slight softness/politeness to the presentation, but I'm not quite sure if this is just the sound of neutrality or some intentionally added smoothness. It's nowhere near the level of an HD 650, but it is something that isn't there on the Utopia or HD 800 series for example. The Clears simply do not have that ultimate last bit of resolution/resolving capability, but on the other hand this can also be a very good thing if you´re listening to a lot of less than perfectly mastered mainstream records. I sure am. Almost anything usually sounds at least quite good out of the Clears (vs. try listening to mastering "classics" such as Red Hot Chili Pepper's Californication on the Utopia/HD 800 series).
Last but not least, the Clears just like all of the high end Focal headphones sound exceptionally fast, punchy and dynamic. The energetic and forward presentation more or less grabs your attention and holds it. It doesn't do this as much as the Utopia, but the same style is still there. Sure there is a hint of added smoothness this time, but I would never call these "easy listening" headphones like especially the HD 650 are. They also handle high volumes well without ever sounding strained or grainy, nor do they get confused when a lot of stuff is happening at the same time. These features are what makes them so addictive, but on the other hand I think due to this and the heavy weight a lot of people may want to complement these with a different can for background listening. My current solution is to listen to these on very low volumes when trying to concentrate on something else, but I do often miss my HD 650 for this purpose. Maybe I'll buy them again someday.
Conclusion:
All in all I'd say these are the best HD 600 series upgrade in the industry right now. It's a bit odd that they eventually came from Focal, but since the "Super HD 600/650" is something a lot of enthusiasts have been waiting for (including me) I'm just super happy that these were finally made. I've been an almost lifelong Sennheiser fan and have mostly used their headphones, but now for the first time my main go to cans are something else. I haven't used my HD 800 S much since I got these, which probably tells just as much as this review. They will most likely be sold on in the near future, possibly to help fund a very likely HD 820 purchase as I'm in need of a closed headphone.
The Clears aren't technically superior overall to the HD 800 S (except in bass extension/quantity, speed, macrodynamics and mids resolution), but they are definitely more enjoyable to me due to the fantastic tonal balance and their lack of any major SQ drawbacks. They are simply a superb all rounder suitable for any genre: clear, balanced, dynamic and always draws you into the music.
Looking back the Clears are in my opinion exactly what the Elear should have been, but it would have been too much for a company new to high end headphones to achieve with their first try. These are still very expensive headphones, but the performance and build quality does fit their price. You are getting a lot in return. I'd easily take the Clears with a 250 euro all in one DAC/amp over any speaker setup even remotely in the same price range. Personally I would have preferred these to sell for 1250 euros and keep the the case/extra cables optional, but even at the 1500 euro price these can be considered good value when you look at the prices top of the line flagship headphones tend to sell for these days. The Clears now leave both the Elear and Utopia in a weird position. At 1000 euros the Elear is just way too expensive now considering how much better the Clears are. The Utopia on the other hand while technically superior in certain aspects, can (also) be argued as having a significantly worse tuning and being too expensive considering how close they are in sonic performance. I'm almost certain its successor will take notes from the Clear, but for now it suffers greatly from being launched back in 2016.
As for downsides there are several, but most of them have nothing to do with sound quality. The biggest minus is the heavy weight and while the ergonomic design works for my head shape, I would guess that it is probably less universal than the one on both the HD 600 and HD 800 series. Other potential issues are the high prices for replacement pads and the non-modular headband design which may end up being very expensive to replace someday. I've also read that the warranty is non-transferable, so buying these off the used market is a big risk as no one really knows how well the drivers will last (vs. there have been reports of Utopia drivers failing and the Elear drivers hitting mechanical clipping on high volumes). Many enthusiasts would also have preferred these to have a higher impedance to make them match better with traditional high power amps, but on the other hand this makes them much less demanding of source electronics. You certainly get the most for your money when buying actual headphones, plus "upgrading" source electronics can easily lead to a vicious and very expensive cycle of never ending sidegrades (it did for me at least). With these you won't have to worry that much about your source. That being said these are of course revealing enough to highlight better electronics, it's just that you get to 90% or so of what these can do for quite cheap.
Sound quality wise the only major nitpick I have is that these lack the final 5% or so of resolution headphones like the HD 800 S and the Utopia can pull off, but at least without EQ I still find these far more enjoyable than either of those. These are my new favorite headphones out of everything I've heard so far. Props to Focal for their contribution in pushing the high end headphone industry forward. It's going to be interesting to see how Sennheiser, Beyerdynamic and others are going to reply to the Focal high end lineup as they inevitably sooner or later will have to.

That being said these won't disappear on your head though: they just weigh too much for that to happen, but they are remarkably comfortable for their weight. Your mileage may vary though: it all depends on your head shape. As usual always audition before buying.
Another key to the good ergonomics is also in the headband design. At first glance using a lot of aluminium sounds like a horrible choice for engineering a comfortable headphone. Just try riding an aluminium bike compared to more flexible steel one for example. Look closer however and you'll be surprised at how much the cups move/swivel. The headband also flexes in several directions. All this is done with an elaborate suspension mechanism inside the headband. To me it looks and sounds like there are lot of springs involved. The downside is that there is some mechanical creaking/clicking sounds when you swivel the cups, but never when you are actually wearing the headphones. I´ll be keeping a close eye on this though to see if it ever gets any worse. Another minus is that this design probably makes the headband replacements very expensive.
What can I say... Focal have done their homework. This isn't a quick "let's just throw something on the market, our brand name will sell it" cash grab. It's obvious they have invested significant R&D resources into doing this well. In other words they are in this to seriously challenge Sennheiser and others in the long game. Good times to be in this hobby!
Sound quality:
I've now used the Clears for around a month and these have basically replaced my previous favorite HD 800 S as my daily go to headphone. This is already becoming a cliche to say, but these headphones opened my eyes towards placing more value on tonal balance. During my ~decade of following this hobby I had become so used to high end headphones being worse in this regard than the legendary HD 600/650 that I basically started taking these flaws for granted. The most important thing to say about the Clears is that are in my experience the first high end headphone that doesn't suffer from this. The tonal balance is simply the best I've ever heard. They just sound ”right” with no major dips or spikes anywhere in the frequency response. This in combination with the low distortion makes them headphones you can easily turn the volume up with without them almost ever sounding fatiguing or harsh. What they don't do however is making you want to turn up the volume all the time, which is actually a really good thing. It my experience that only happens with headphones with severe tonality issues like the Elear with its upper midrange dip or headphones that roll off the treble too much (= you easily keep increasing the volume to get the vocals or treble to sound right, but they never will). I wouldn't be surprised to see these end up being very popular for pro audio purposes too (and actually Focal did just launch the Clear Professionals; different paint job/accessories, but same sound).
Let's start with the bass. Overall to my ears it has the best bass performance in an open dynamic headphone so far. The measurements on various sites look wonderful and it doesn't disappoint subjectively either. While the bass lacks the absolute extension of the high end planars, it goes very deep and does not roll off much in the sub bass range like most open dynamics do. Slam is great for an open can too. The bass is high in resolution and very clean, although it is not the cleanest or most defined bass I've ever heard in an open headphone. That award still goes to the HD 800 series, but the Clears are not far away either. Is it more enjoyable however than the bass on the HD 800 series? Due to the much better extension and quantity the answer is absolutely and that's what counts. The HD 800 sounds lean and thin in comparison while the Clears sound neutral. The bass is also miles beyond the in comparison muddy mess the HD 600 series outputs.
The bass to midrange transition is well done, but there is some very slight bass bleeding into the midrange. I would not pair these with electronics that emphasize bass through adding harmonic distortion for example. This issue is mitigated by using more neutral sources. Personally I feel the bass quantity is just about optimal as it is enough to make a lot of contemporary genres like electronica sound good without sacrificing more traditional audiophile genres like jazz/classical/vocals.
When it comes to the midrange the first thing I noticed was the fantastic sense of realism and the lack of any hint of sibilance. Vocals often sound so real I've been rediscovering a lot of my favorite vocalists lately. The mids are also more neutral compared to the somewhat recessed mids on the HD 800 series. I'm not sure if it's the more neutral presentation, but here to my ears the Clears also surpass the HD 800 series in midrange clarity and resolution. These headphones get the most important part of the frequency response just right. The measurements do show a small dip in the upper midrange though, but I could not have picked that up if I didn't know about it.
While the bass and midrange forms a coherent whole, the highs can sometimes sound a bit disconnected from the rest. This is probably a deliberate tuning choice to enhance the soundstage. It's actually a bit similar (yet not as drastic) to what Earsonics did with the SM64 IEM. I find this effect quite enjoyable on many records, but sometimes it doesn't work that well. It's a very small issue, but something to keep in mind. I rarely notice it as it doesn't bother me much. That being said the highs, while tonally more balanced compared to the rest of the spectrum than in the HD 800 series, are less smooth than on the HD 800 S. This isn't apparent on all songs, but sometimes you notice it. For example the Clears while generally being less "hey look at this click in this record!" than the HD 800 series, on some songs they can actually highlight this kind of stuff more, especially in some pop music. For example on Taylor Swift's Blank Space there's an odd percussion or distortion effect that sounds downright nasty on the Clears. You can still hear it well on the HD 800 series, but it seems more annoying on the Focals. That being said these are still a much better choice for contemporary music due to the more balanced tonality (vs. HD 800 series treble emphasis with a lack of bass extension). I'd also say that the highs have a higher level of resolution on the HD 800 series and it's not just due to the fact of how emphasized they are. The HD 600 and HD 650 are both smoother in the highs as well so if you are very treble sensitive this may bother you. For me however the treble here is still a very smooth listening experience, on a completely different level than the Beyerdynamic T1 mk2 for example.
When it comes to the soundstage that is quite intimate for an open headphone. I would characterize it as listening to music in a somewhat narrow tunnel while sitting closer to the musicians (vs. back row in a concert on HD 800 series). This is both a good and a bad thing and ultimately there's no right or wrong here. This is the more traditional headphone presentation. Both approaches are enjoyable though and have their own strengths and weaknesses. I find the Clears presentation more emotionally engaging in general, but I do like the speaker like sensation the HD 800 series pulls off too. Imaging within the fairly small soundstage is really sharp though and there is also a good amount of air between the instruments. You quickly get accustomed to the presentation style and after a while you don't really notice it much anymore. Instrument separation is fantastic, much better than on the HD 600 series although still not quite as good as on the HD 800 series.
There's a slight softness/politeness to the presentation, but I'm not quite sure if this is just the sound of neutrality or some intentionally added smoothness. It's nowhere near the level of an HD 650, but it is something that isn't there on the Utopia or HD 800 series for example. The Clears simply do not have that ultimate last bit of resolution/resolving capability, but on the other hand this can also be a very good thing if you´re listening to a lot of less than perfectly mastered mainstream records. I sure am. Almost anything usually sounds at least quite good out of the Clears (vs. try listening to mastering "classics" such as Red Hot Chili Pepper's Californication on the Utopia/HD 800 series).
Last but not least, the Clears just like all of the high end Focal headphones sound exceptionally fast, punchy and dynamic. The energetic and forward presentation more or less grabs your attention and holds it. It doesn't do this as much as the Utopia, but the same style is still there. Sure there is a hint of added smoothness this time, but I would never call these "easy listening" headphones like especially the HD 650 are. They also handle high volumes well without ever sounding strained or grainy, nor do they get confused when a lot of stuff is happening at the same time. These features are what makes them so addictive, but on the other hand I think due to this and the heavy weight a lot of people may want to complement these with a different can for background listening. My current solution is to listen to these on very low volumes when trying to concentrate on something else, but I do often miss my HD 650 for this purpose. Maybe I'll buy them again someday.
Conclusion:
All in all I'd say these are the best HD 600 series upgrade in the industry right now. It's a bit odd that they eventually came from Focal, but since the "Super HD 600/650" is something a lot of enthusiasts have been waiting for (including me) I'm just super happy that these were finally made. I've been an almost lifelong Sennheiser fan and have mostly used their headphones, but now for the first time my main go to cans are something else. I haven't used my HD 800 S much since I got these, which probably tells just as much as this review. They will most likely be sold on in the near future, possibly to help fund a very likely HD 820 purchase as I'm in need of a closed headphone.
The Clears aren't technically superior overall to the HD 800 S (except in bass extension/quantity, speed, macrodynamics and mids resolution), but they are definitely more enjoyable to me due to the fantastic tonal balance and their lack of any major SQ drawbacks. They are simply a superb all rounder suitable for any genre: clear, balanced, dynamic and always draws you into the music.
Looking back the Clears are in my opinion exactly what the Elear should have been, but it would have been too much for a company new to high end headphones to achieve with their first try. These are still very expensive headphones, but the performance and build quality does fit their price. You are getting a lot in return. I'd easily take the Clears with a 250 euro all in one DAC/amp over any speaker setup even remotely in the same price range. Personally I would have preferred these to sell for 1250 euros and keep the the case/extra cables optional, but even at the 1500 euro price these can be considered good value when you look at the prices top of the line flagship headphones tend to sell for these days. The Clears now leave both the Elear and Utopia in a weird position. At 1000 euros the Elear is just way too expensive now considering how much better the Clears are. The Utopia on the other hand while technically superior in certain aspects, can (also) be argued as having a significantly worse tuning and being too expensive considering how close they are in sonic performance. I'm almost certain its successor will take notes from the Clear, but for now it suffers greatly from being launched back in 2016.
As for downsides there are several, but most of them have nothing to do with sound quality. The biggest minus is the heavy weight and while the ergonomic design works for my head shape, I would guess that it is probably less universal than the one on both the HD 600 and HD 800 series. Other potential issues are the high prices for replacement pads and the non-modular headband design which may end up being very expensive to replace someday. I've also read that the warranty is non-transferable, so buying these off the used market is a big risk as no one really knows how well the drivers will last (vs. there have been reports of Utopia drivers failing and the Elear drivers hitting mechanical clipping on high volumes). Many enthusiasts would also have preferred these to have a higher impedance to make them match better with traditional high power amps, but on the other hand this makes them much less demanding of source electronics. You certainly get the most for your money when buying actual headphones, plus "upgrading" source electronics can easily lead to a vicious and very expensive cycle of never ending sidegrades (it did for me at least). With these you won't have to worry that much about your source. That being said these are of course revealing enough to highlight better electronics, it's just that you get to 90% or so of what these can do for quite cheap.
Sound quality wise the only major nitpick I have is that these lack the final 5% or so of resolution headphones like the HD 800 S and the Utopia can pull off, but at least without EQ I still find these far more enjoyable than either of those. These are my new favorite headphones out of everything I've heard so far. Props to Focal for their contribution in pushing the high end headphone industry forward. It's going to be interesting to see how Sennheiser, Beyerdynamic and others are going to reply to the Focal high end lineup as they inevitably sooner or later will have to.
