Pros - imaging,soundstage,detailed high,mids and lows,smooth,comfortable
Cons - unforgiving on poor recording or wrong equipment.
The HD800 is my first expensive headphones.
its really comfortable to wear it and sounds great through my Fostex HP-A8.
the treble is smoother than i first thought it would be but its still considered an bright and detailed headphone. bass is very neutral and punchy and mids is also very natural and uncoloured in my opinion.
some people may find it too bright or not enough bass when paired with the wrong amp.
the best part that i find with the hd800 is its imaging. i feel like band is playing in an nice big stage in front of me and every instrument is seperated and can be heard easily.
Pros - Extremely comfortable especially you need space, or if yo have a big head, drop in feels just nice.
Cons - None
Airy, extremely transparent, silky and fluid sound.
Pros - Amazing soundstage & instrument separation, detail monster, awesome PRAT and bass, top notch mids
Cons - Sometimes sibilant, very fragile
The last time I listened to HD800 impressed me so much that I had to buy a pair for myself:
Since then, the HD800 have grown on me even more. These headphones are absolutely spectacular on the right gear, in my case the Burson Conductor .
These headphones deserve post of their own. I almost feel responsible doing this, as I feel that I haven’t done them justice in my first post and I have to make up for it.
Lets take this from the start.
In my opinion they look quite nice and I really enjoy their futuristic design.
Every time I put them on I feel like this:
How I actually look like:
However, they seem really fragile to me. I have touched the silver grill by mistake and left a print there. My hands were clean, but still managed to do that. I couldn’t remove it so it is still there and it bugs me . Audeze LCD2 feel like a tank compared the senns.
I liked the stock cable from HD800. The build quality seems to be very good and it looks nicer than the usual stock cable ( LCD2 for example ). One thing I don’t like about it: the splitter seems to be made from cheap plastic and the cables that go from the splitter to the cups don’t look like high quality to me. Actually, I know a friend that had some problems with that portion of the cable, meaning that in time it opened up. This seemed to have happened to more owners.
I feel I really must be extra careful and treat them with more care. Don’t put them directly on your desk as the paint may chip off. I always put them on something more cushy and not directly on a hard surface.
On the comfort side, I don’t think I have ever wore a more comfortable headphone. I really forget they are on my head after a while.
So let’s get to the most important part, the sound. So many things to say and so few words to express all I would like to say about these headphones.
I will tell you my impressions on a few songs.
ACDC – You Shook Me All Night Long
The first thing that struck me was the bass and the guitars. The bass is not at all shy. It is very present with a very nice punch and tightness. Of course the sound was multi layered and very airy. The PRAT was awesome and toe tapping. One thing I had to do while listening to the song was to lower the volume as the treble got a little too tiresome. The fact that I lowered the volume was not quite a bad move as I really got to enjoy the song like this with no problems. Yeah you heard me, I like rock on HD800. It is a little bright sometimes but lowering the volume solved the problem. It was quite ok as I can really enjoy music at even lower volumes with HD800 .
Pink Floyd – Dark Side of the Moon – Time
Damn… The bells at the beginning were absolutely awesome. Every bell was so clear and so well defined in its place. The sounds came from all directions and you could easily concentrate on each and get it’s original location. The sound was pouring effortless and the dynamics were incredible. The soundstage is exceptional and you forget you are listening to headphones.
Infected Mushrooms – IM The Supervisor – Noon
Dat bass… Yes you heard me… Who said HD800 hasn’t got bass, clearly didn’t hear it on proper setup. The bass is so punchy, so deep and so damn fast. The PRAT on this song was awesome. The instruments were very detailed, excellent placed in space and very present throughout the song. The sound came effortless and HD800 handled it with extreme ease.
Tristania – Illumination (symphonic gothic metal)
One word. Excellent! The bass is superb. It really hits you with force and real impact. It is so punchy and so present. The sound was very opened and all the instruments were so well separated and well placed. The sound is multi-layered and not one instrument blended in with another. The voice could use a more natural tone but overall I really loved the song on HD800.
Andre Rieu (Dreaming) – Air (J.S. Bach)
The sound-stage is amazing. The sound is so opened that if you close your eyes you forget you are listening to headphones and that you are at home. You can see yourself in the concert hall, you can see the orchestra and pinpoint every instrument there. The details are amazing and the dynamics are the best I have ever heard in a headphone.
Leonard Cohen – The Traitor
The instruments in the beginning of the song are awesome. The details really tickle your ears. Again the instrument separation is absolutely beautiful. There is so much air between the instruments. You can hear everything and you can easily concentrate on the furthest instrument and still hear it clearly. The voice is quite nicely reproduced and has an excellent texture. It is not as natural as on LCD2, but the reproduction was still awesome.
These headphones are the best headphones I have heard to date. The soundstage and openess of the sound is exemplary on them. I sometimes really forget I am listening to headphones. The sound is so multi-layered that on the the most crowded songs I have listened to, never did I found, not even once, that two instruments blended in the same layer.
The imaging and sound positioning is excellent and you can really pinpoint the location of any sound with great ease.
They truly are detail monsters. The get all out of that recording. I expected to be annoyed by lower resolution files, but I enjoyed them greatly even on some mp3s I had listened to. Sometimes I got scared, as I thought some sounds came from my room and I was preparing for battle if any intruder had broken in my secret audiophile lair:
Ok, the bass…These headphones DO NOT lack bass! I repeat…they DO NOT lack any bass! Their bass is awesome, actually. It goes very very deep, it is very punchy, very fast and knows how to jam.
The mids are top notch too. The instruments and voices have a wonderfully detailed texture.
The voices are well reproduced but they could use more body and a more natural tone.
I did not find the HD800 to be bright headphones. They are very neutral to me. The times I thought them to be bright I realized the song was at fault being a bright recording. When something was bright on HD800 was even bright on LCD2. Be careful as there are many bright recordings out there. So the treble is very very well defined and is very sparkly when it is needed to. Unfortunately the sound is a slight sibilant but usually when it got too sibilant it was the recordings fault as well.
The dynamics & micro-dynamics on these headphones are excellent . I can really listen to lower volumes with HD800 and still be fully satisfied.
I have used it on some movies as well. They excelled here as well. In crowded open spaces you really feel that you are in that place. It is quite incredible.
I am going to give you a little advice: Don’t use them on a HD horror movie if you have heart problems!
Pros - Accuracy Comfort(moddable with 30 minutes fully reversible work)-revision Nov 2015-rev 2016 Bass lifted treble spike toned down
Cons - Price- First hours of listening were a little worrying-(treble may eventually grate)Revision Nov 2015 new rev Nov 2016 grating treble all but gone
This review is based on my honest impressions of the HD800. I have no technical background little technical knowledge but I listen to music an awful lot. This comes from the heart and I in no way intend to cause any personal offence to any of the gear anyone else has. I simply wish to put on record what my personal findings have been on this set of phones and the reader can compare to other reviews out there.
First of all, I have to say it has not been possible to find a way to give you an unbiased comparison of these headphones against any others on the market. This is because double blind testing only works when you are using ancillary equipment.
If you know your existing headphones then you know how they feel on your head so this immediately destroys any chance of knowing what the true differences are. Leaving aside all the tricks your ears can and will play on you....
This is a good and a bad thing. On the one hand it gives reviews like this an added importance to the prospective buyer and on the other hand theee is no esy of proving whether any of this is correct.
The closest one might get to a really good comparison would be those people lucky enough to have a sound card dac or headphone amplifier that had 2 headphone outputs. Switching between headphones could therefore be done faster and the memory of the sound characteristics of each arguably clearer in one's mind. I believe jude has a benchmark dac that has this facility. The added complication is that every headphone has a slightly different sensitivity so volume matching is arguably needed. I have not got these facilities they are more suited to the regular reviewers out there.
I have had the hd800s since early December 2012 so have listened to them for several hundred hours. I have owned denon ahd2000's westone um2s shure ecl5s ue triple fi 10s monster gratitudes klipsch x10is srx mk3 pros and audeze lcd2's during this time. A comparison between these headphones is all I can do. There might be headphones out yhere that blow the hd800s out of the water for the type of sound quality I like but that's the mystique of our hobby- we will never truly know what the best out there is. David Mahler must be getting there with the number of top end phones he has I guess. But for mere mortals....
The hd800s are my favourite headphones. Whatever I plug them into whatever music I listen to. When it is practical to listen through them (they leak a huge amount of sound) they're amazing. The music is reproduced in a way I never believed was possible until I heard them. The audeze lcd2's are renowned for the live feel and the bass they produce and their beautiful finish. All of this I believe to be true from the time I owned them. My ears much preferred the sound of the hd800s and I will try to explain why.
There is something about the precision of the mix of the music the wideness of the sound that I have not experienced with any other headphone in the same way. The hd800s to my ears excel in this aspect. You will read numerous articles which will make you think twice about spending so much money on these phones. I have read they need hugely expensive headphone amplifiers , dacs, cabling, modding, 100s of hours of burn in time, special recordings, special ears probably. The list is endless. Who knows maybe some of that stuff is right especially for those who have pursued those paths to the nth degree.
Some of these paths are expensive toll roads, from my viewpoint I think I'll catch the bus
I am therefore not going to describe the hd800s as having shortcomings of needing any of the above because my ears are telling me they don't. Which is surely good news if youve just spent $1500.
Other criticism I've read is that they sound harsh or the treble has too much 'sparkle'. Not to my 46 year old ears they don't. Not one bit. The higher frequency stuff sounds just great. Another criticism levelled is that they lack bass. Again, I have found this to be untrue. All instrumemts are presented accurately so if there's metallica softly tapping way at the drums on enter sandman or the orchestra limbering up on jeff waynes the eve of the war it's worth taking some time out to hear it if you haven't before.
The only detrimental thing I can say beyond the obvious that they leak sound is that when I first listened to them out of the box they sounded very thin and strained like a cheap pair of iems. This was quite worrying to me. They started to improve after a few minutes and certainly gave me a sigh of relief after 30 minutes when I realised my new phones werent broken. Whether this phenomenon was what is described as burn in or whether it was down to the headphones being cold having been stored in a box for a long time I could not tell you. I left the phones connected to an ipod night and day for a week listening to them when I had a chance. This was just as much to make absolutely sure there wasn't a manufacturer fault than it was to burn them in and it did the phones no harm at all in the process. In hindsight I had nothing to fear but for those of you buying new I would advise it for the peace of mind that you haven't got a broken pair
I find most of the headfiers out there are on a budget. Am I right? If I had a budget of $1500 and I wanted to get the best sound quality I could I would buy a pair of these 2nd hand and spend the rest on wine, women (your loved ones deserve a treat for letting you get these), and song.
I hope I have not trodden on anyone's toes or caused anyone any upset in writing this. It was a simple impulsive wish to share some of the pleasure I have had in owning this amazing set of headphones.
I thought I would tell you of what life is like after a few years of use. I have dropped these phones a few times and had to repair the stock cables at the termination, they have been taken around with me during my journey to and from the various places I live so they show signs of wear.
The HD800s still live up to their initial impressions, I have bought and sold many other phones; LCD2.2, T1, Stax Sigma Pro, IE800, X11i, Alpha Dog, Encore Pro Studio, Stance S1,T20 etc. I have listened to many other phones including the SR009, Orpheus, K1000, Abyss, GS1000i, PS1000, Ultrasone, Noble, LCD3,W1000,HE560 and HE1000. Whilst some of these have been better sounding to me (SR009,K1000,HE1000,Orpheus,Abyss,HE560) I have not been tempted to spend those sorts of sums on replacement.
Some 2 months ago I decided to mod the HD800 using the Anaxilus Mod. I was really disappointed with the results, to me they sounded muffled, lost too much of their soundstage and were too prominent in the bass. Rather than discarding all the research and damping material I decided to tone down the effect of the mod. I put wool felt over the metal rings of the driver reducing the thickness of the original mod by a factor of two thirds.
The cutting is crude, the felt doesn't 100% cover the surface of the ring. It doesn't even stick hard and fast the surface. Yet the felt does what it needs to do.
This has made a noticeable difference in bass response and ringing around the upper treble region, although a word of warning ; the upper mids and treble region is where I believe the magic of the illusion of the huge soundstage is created. Of course the size and angle of the drivers plays a part in the soundstage too , the mod does pull it in. The soundstage is further refined and pulled in with an EQ I have set up on my Audivarna Plus music player.
I am reaping the fruit of my labours with these phones, in spite of the HD800S launch. The S Model is intended to rectify some of the perceived shortcomings of the 800 Model, I have to say I have changed the stock sound of mine using damping and eq to the point where I have no interest in replacing them with the S Model.
There has been one recent major purchase; this is the HE6 and a huge speaker amp based on the First Watt F6, @dill3000 diy built "The Mini Beast". More on that in another review. The HE-6 is a different tone and the soundstage is altogether different. The HD800 is still with me and enjoying a new lease of life despite the HE-6.
Revision Nov 2016
The half felt half lambswool has now been replaced with a full lambswool layer to the ring around the drivers of my HD800.
Listening to the S model made me realise there was still more that should be done with these phones. My friend @dill3000 pointed out to me @Sorrodje had another layer of sophistication to add to the mods already done out there.
Dillan got some resonators and I set to work on the drivers. 10 minutes later and I was finished. They work! Wonderful work @Sorrodje. Thank you. You have made the great even greater.
The HD800 , at £1099 , is looking at ever more of a bargain. Although , even with the mods , I would put my money on the S model for the extra £100. the soundstage is not quite so wide and the imaging perhaps not quite so pin sharp, but I think the tonality still just edges it.
Pros - Sound Stage Presentation, natural balance and tone, generally top notch sound quality
Cons - They are way too expensive for just a pair of headphones
Like with the HiFiMAN Headphones these are tantalising. If they cost 400 squid and could be driven well by a smart-phone or laptop headphone output, I’d buy them on the spot. At three times the price and only suited to home use, I can neither justify the expense nor do I have the slightest inclination to do much headphone listening at home. And I want the “magic” the HiFiMAN planar’s weave too.
Combine the best of the Sennheiser and the HiFiMAN Phones, sell them at £ 700 and there is a good chance that the queues in front of the headphone shops start approaching those in front of Apple stores when a new iPhone comes out.
Read the whole review here:
Pros - It makes my LCD2.2 leave in dust
Cons - It keeps me away from other flagship headphones for certain period
But why i give 4.5 stars?
Because Stax009 is better to my ears.
Pros - 21st Century Design. Detail Kings. Soundstage Kings. Comfort Kings.
Cons - Price. Needs Expensive Amplification.
Not that there haven't been a hundred thousand things written on this most-controversial headphone-- but what the heck are we here for if not to give our opinion, right? So sit back with a cup of coffee, while I'll tell the story of my HD 800 experience.
It's funny-- there's a growing Apple-Microsoft type environment growing in the Head-Fi community. It's between HD 800 owners and fans, and Audeze owners and fans. If you read any forum with the omni-present headline "Which Headphone Should I Buy?" the two sides make themselves known in subtle ways. "Well if you're looking for comfort, you can't go wrong with the HD 800," writes one post. "Way more comfortable than the LCD-2." Next post: "What? You're crazy! I've had my LCD's cranked on my head for like 10 hours today. Look! There's still on my head and I didn't know it!" "Well Sennheiser has been around for seven hundred years. You know they'll be here after the world explodes and you need new earpads after the firestorm scorches them." "At Audeze, they hand craft every single component and skip Valentine's Day because the love goes into their products." And on and on the debate goes.
Point is-- Everyone is going to be predisposed to one type of headphone or another. I haven't owned an Audeze headphone yet. I will in the next year or two. Right now I'm still finding the edge of the envelope for the HD 800, and it's getting interesting.
I started my Head-Fi journey in the shallow end. I needed wanted a custom in-ear headphone which really blocked out sound, so I stumbled across Ultimate Ears Reference Monitors and went through the process of acquiring a pair. Amazed by the fidelity, I started looking for opinions and found Head-Fi and Headfonia-- which led me to the Slim Pico Amp. Impressed, I thought I'd try an open ear set of cans for home-- so I bought the HD 650. Then I thought-- let's put some power down-- so I bought a Burson 160D. Great, but lots of treble-- let's find a smooth tube amp! Enter the Woo WA6. Then I rolled a thousand+ dollars in tubes into it-- and bought the HD 800. You can already see-- this story isn't going to end well.
The HD 800 out of the Burson and the WA6 were a subtle upgrade over the HD 650. The bass was certainly tighter, the soundstage wider, but honestly-- the change between the two wasn't all that remarkable. Still, I kept the HD 800 figuring I can scale them up if I wish, and they were more comfortable on my head than the HD 650-- so the HD 650 were sold so my wife wouldn't murder me.
Sure, there were other headphone purchases-- Audio Technica ATH-50s (those still live at work), Grado SR225, Beats (yes, Beats-- wanting to see what the fuss was about-- that's another review), and some in-ears-- Shure SE425 (still for sale), Klipsch, HifiMan, among others. But the main focus now was my home rig and bringing the best out of my HD 800.
The WA6 tube rolling experiments got all the way to a NOS 1957 GZ34 rectifier with a metal base, which cost around the price of the amp-- The HD 800 responded every step of the way. The bass deepened as the headphone broke in, I upgraded the cable to Toxic silver (exciting another debate over whether pure copper is a better match for the HD 800). Things were improving but the knock still was that the sub bass wasn't kicking, and the highs out of the Burson made that combo particularly bright to my ears-- damn near to the point of sibilance.
In October, one Head-Fier suggested-- maybe you should think about more power for the HD 800, suggesting a move to the WA6-SE. I started an eBay search. This wasn't going to be pretty.
After losing a few auctions-- something really bad happened. A Woo WA5LE appeared-- and no one was bidding. Yep. That was the winner. $1800 dollars later I started looking for FedEx trucks everywhere I went.
This was a major change in the HD 800. The full range of the audio spectrum was now pumping through my skull. It was like getting a much-needed pair of glasses after years of squinting. I never realized how power hungry this headphone really was. Sure, I can drive the HD 800 with a Fiio E17, they are efficient headphones, but to bring this set of cans to life, it wants pure, clean power, as much-- and as clean-- as you can muster.
I'm not talking about a marginal improvement anymore. Here's my best analogy: Say I purchased a Ferrari. I get behind the wheel and take it for a spin. Well, it's a Ferrari, so I'm going to be impressed. What I didn't know-- is that the car came only with a four-cylinder engine. And while I thought I was getting this good performance, when I dropped a (edit) Prat & Whitney jet engine in, suddenly you are holding on for dear life. Everything about the car's characteristics changed. The car can move with the four-banger, but it was really made to handle a lot of power. Same goes with the HD 800.
Now here's another problem with this new system-- every musical flaw is up front. Putting MP3 files through it-- you hear every artifact and dropout. It's brought the worst out of the Burson's DAC stage. So much so-- I'm now selling the Burson for a cleaner DAC.
Stepping back for a second-- you have to wonder-- what was wrong with the HD 650 and the WA6? Nothing. I'm crazy. I admit it.
But for folks who complain that the HD 800 lacks sub-bass, my first question from now on is going to be-- What are you using to drive it? Because with the right power, you understand why this is a $1500 dollar headphone. It's the closest thing I've ever heard to sonic perfection-- yet I'm still rolling thousands of dollars in tubes through the WA5LE, to see where the edge of the envelope is with the HD 800.
Pros - natural bass, build quality, comfort, fast and detail, alike high end stats.
Cons - peaky treble, highs can be slightly bright on some tracks, paint chipping, may be expensive for some
The HD800's has been around a long time so I'm going to wrap up this review in a few paragraphs.
Having owned 3 HD800's at one stage, Serials 51**, 136** and Purrins 103**.
Going through all 3 before selling the first two and keeping only Purrins HD800 I bought off him, the early serial based HD800's are to my ears a bit more bass light and more warmer then my original serial 136** and purrins 103**.
I ended up selling mine and the early serial based HD800 and was thinking of selling purrins one due to moving onto speakers but I thought maybe I should keep it because its got the magical touch from purrin due to all the CSD plots he does LOL.
Anywho, the HD800 paired with my Beta22 amp sounds extremely good, revealing some detail that I've never heard from my tracks similar to the amount of revealing detail some Stax rigs I've auditioned and owned. Certain music can sound slightly too bright, some music with vocals can result in the voice sounding like it's pronouncing everything with a "Sssss".
Following the threads here or Innerfidelity (thanks to Tyll), performing the Anaxlius mod with a thicker but more denser felt material can fix the treble problems a bit, generally a bit of eq can fix this problem.
Most people say the HD800s are too bass light or no bass at all, but with proper amping, you can put on some bass heavy tracks and put your hands over the outside filter dome and you can really feel the bass vibrations. I actually gave the bass of the HD800's a pro because it actually sounds very natural, if I wanted bass, I'd just grab my LCD2's or some of my other bass heavy can's.
Surprisingly for a plastic build, it is surprisingly well built and durable, the only thing I can complain about it really is the paint chipping problems that people have, the silver paint really is prone to chipping off no matter how much care is taken with the headphones, which is why I'm in the process of repainting mine through a professional painting service, unfortunately I've emailed Colorware before to do a one off type of job and they said the reason they stopped the custom painting services through Colorware is due to warranty problems and modded headphones.
Other then that there really isn't anything else to say about these headphones, if there is one headphone you should try before moving onto high end electrostats it is the HD800's as there detail, accuracy and speed of its dynamics are similar to that of high end stats like the 007 MK 1/2's. etc.
Pair the HD800 with a top of the line solid state amp such as the Beta 22 and you will be wowing at every song you re-listen to that you've heard probably heard a hundred times.
Pros - OVERALL SOUND QUALITY & SIGNATURE, WEARING COMFORT, OPENESS, BUILD QUALITY, MADE IN GERMANY, ALCANTARA, ETC.
Cons - PAINTING, PRICE OF SPARE PARTS, SOMETIMES PIERCING HIGHS
ACHTUNG! This is a completly subjective -or let's say in some aspects probably "subjective-neutral"- review.
The HD800 A condensed account after nearly two years of daily use
My setup: Denon DVD-3910 SACD/DVD-A/HDCD/CD/MP3-Player -> Sommer Cable SC-Classique -> Meier Audio Corda Cantate.2 -> Sennheiser HD800
- relatively high prices for spare parts (a pair of ear pads costs about 75 EUR)
- relatively damageable silver paint
- not comfortable for (very) small heads
- sometimes piercing highs in bad recordings
- not suitable for music that requires tons of bass
- not suitable for music files encoded with a low quality
- not suitable for very bad sources and amps
o very wide soundstage
o futuristic design/look with nice Volkswagen silver metallic paint
o technical ability
o mainly plastics, some metal
o the price might seem to be high, but compared to e.g. SR009, it's kind of a steal
o unique ring transducer
o somewhat unforgiving sound
o diffusfeldentzerrt (just a joke, because it's a normal feature and I like this German word... )
+ easy to clean inside and outside
+ washable and replaceable pads
+ spacious earcups (the ears stay fairly cool)
+ nice feeling Alcantara fabric
+ luxuirous wearing comfort (for large and medium head sizes)
+ detachable cable
+ overall good haptic, finish and build quality
+ very good cable quality
+ can easily and reversible be modded with foam, felt or slices of wood, to raise the bass level, tame the highs and very slightly change the sound signature, too
+ "Made in Germany" (Hooray!!! - no patriotism, I only want to express, that it's not "Made in China" like most audio/video products [even expansive ones of well known Western/Japanese/South Korean brands] today)
+ overall very pleasing sound quality and general sound signature
+ the Neumann/Klein&Hummel monitors sitting on your head (Sennheiser = Neumann/K+H)
+ one of the best headphones for classical music (opera, chamber, big orchestra, organ, etc.) and jazz
+ suitable for audio mastering
+ absolutely stunning with good audio recordings
+ also pleasing with medium quality rock/pop/some electro/"whatever"
+ analytical sound with a fun factor
+ extraordinary nice voice rendering
+ overall relatively balanced sound
+ no audible resonances
+ low distortions
+ very open and airy sound
+ holographic sound image (deep and very broad)
+ (somewhat) natural sounding coloration
+ excellent instrument separation
+ extended, detailed and fast bass
+ natural and detailed mids
+ very resolving highs
+ no artificial sound (like e.g. some "Ultrasones")
+ superb and refined detail retrieval
+ absolutely controlled sound (manages e.g. Richard Wagner's Götterdämmerung perfectly)
+ very good positioning in width and depth
+ very good at lower volumes
+ is able to play very loud, paired with the right amp
+ better than the best of DT880/600, HD600, HD650 and K701 together
A last thing to mention:
Believe me or not, the HD800 can be perfectly driven by a Meier Audio Corda Cantate.2 and does not need recabling! (IMHO, because I tried out several setups and a highly recommended aftermarket cable and the very good results offered by the stock HD800 didn't get any better this way)
THE END PS: Sorry for every textual mistake in advance!
Pros - They look like something out of TRON
Sold me Edition 9's because of these because they deliver a bigger sound stage and all that compared to the Edition 9's. Maybe it's because the Edition 9's are closed headphones. Whatever they're my 2nd favourite headphone after the SR-009.
