Sennheiser HD 800 S: Tweaked and Delightful...and a French DIY Response Measurements

Measurements
Click on graphs image to download .pdf for closer inspection.

Ed Note: The above plot is for the HD 800 S sent to me by Sennheiser and will be the topic of the following description. I have, however, put together a .pdf booklet of most measurements I took for this review, which includes the other two HD 800 S measured, and a number of other HD 800 measurements both stock and modified.

Raw frequency response plots show some changes in bass response with movement on the head. Impedance plots show the primary driver resonance at 110Hz; raw FR plots show ever decreasing bass below the primary resonance as a result of decreasing driver efficiency below resonance. Ideally bass should be around 3-5dB over baseline below 120Hz. While warmer than the earlier HD 800, the 800 S is still not a bass-heavy headphone.

30Hz square wave shows good shape; the slight downward bowing is from the slowly dropping bass below driver resonance and is not excessive, indicating there are probably no phase shift problems in the bass.

300Hz square wave is fairly good. Initial spike is not excessive; subsequent noise is a tad high, but not excessive. Similarly, the impulse response shows a very responsive initial transient, following noise could be lower, but is again not excessive considering the clean and fast impulse.

Bass distortion is markedly higher than than the previous HD 800. This, I believe, is due to extra 2nd harmonic distortion present in the HD 800 S as can be seen in the plot on page one of this review. Aside from the bass distortion, the HD 800 S has very low distortion elsewhere. An interesting observation is that the HD 600 has a similar bass distortion profile. At some point I'll have a look to see if it's mainly dominated by even order distortion as well. At any rate, I've never considered the bass in the HD 600 as annoyingly distorted.

Impedance plot shows a nominally 400 Ohm impedance headphone with a large primary resonance hump rising to about 650 Ohms centered at 110Hz. Isolation is poor by design in this open acoustic headphone.

With 219mVrms needed to achieve 90dB at the ear, this is not a good headphone for use with portable devices. It absolutely deserves the best amp and upstream sources you can acquire.

Thanks Tyll for the report. Which amp type works best with the 800S in your findings. Was there a particular amp that you enjoyed the most the updated Sennheiser?

Very informative review with multiple measurements, EQ settings, and DIY/mod options. Thank you!

I would choose HD800 over HD800S only if I was mostly listening to well recorded classical music, but since my music collection has all kinds of genres, the HD800S is more enjoyable (relatively to HD800, the HD800S can still be overwhelming with some albums/mastering quality).

Something I found with HD800 vs HD800S is that there is some difference in imaging/soundstage between the two. The HD800S is not as wide and expansive as the original HD800, nothing major, but noticeable when you have two side-by-side and can quickly switch. Is this a side-effect of taming the 6K spike by the resonator? Or maybe I heard this difference due to the more worn pads on my older HD800.

Jazz Casual's picture

Thanks for the thorough and forensic investigation Tyll. So Sennheiser has traded some of the HD800's precision for musicality and an increase in distortion is the by-product. It is interesting that the HD800S, which seemingly editorialises more than the HD800, has also succeeded in knocking it off the wall of fame. I don't have a problem with that - I like Grados after all, but it should ignite heated arguments over whether the modified HD800S is as worthy of being described as a high fidelity headphone as its predecessor. Kudos to Sennheiser for recognising that audiophiles really "can't handle the truth" and offering a more palatable alternative. ;)

Remember when you were a kid, those little puzzle games, where there was an empty space and you had to slide the plastic number pieces around to put them in order? Us headphone fanatics are looking for what goes in the empty space.

I have been waiting for this review for so long Tyll! Was wondering why it took so long :)

The Boss's picture

Tyll, thanks for your review on the HD800S. I also picked up an HD800S recently and whoelheartedly agree with your findings. What I'm curious about is, what can you tell me about HD800S + SuperBAF Mod in comparison to stock HD800S, both in terms of objective measurement and subjective impressions?

In your article you first mentioned the SuperBAF mod and how it tames the sound of a stock HD800. Then you moved on to discussions on resonators and compared the HD800S with HD800SDR(HD800 + SuperDupont resonator). This is great and all, but I've read in SBAF that HD800 should be modded with both SuperDupont resonator and SuperBAF absorber for the best effect. In that vein, since HD800S is in a way a variation of the HD800SDR (or should it be the other way around), wouldn't it make sense to apply the SuperBAF mod to HD800S as well to further tame the sound?

What do you think? Does applying the SuperBAF mod to HD800S helps further and makes the sound more enjoyable overall, or is it somewhat overkill with HD800S (and HD800SDR for that matter) and results in an overdampened, perhaps relatively congested sound?

On a side note, I would like to know whether it is more preferable SQ-wise to leave the dust cover on or off when using the SuperBAF aborober mod.

....this is exactly the kind of stuff that has to be hashed out in the forums. I can only intermittently interrupt with a cogent comment.

Some bed rest and plenty of fluids should help clear that up.

Hi, Tyll, thanks for a very helpful review. One thing I noticed that might be a typo: the upple-treble being withdrawn that causes the human voice to be distant...I think you meant upper-midrange.

Tyll Hertsens's picture
Excellent catch and exactly right. Fixed and thanks again.
zobel's picture

That was a fun read! I play a djembe and an udu, so I knew about Helmholtz resonators, but that was an ingenious use of one to tame that peak! Very nice review, thanks.

johnjen's picture

Excellent work there Tyll!
Its good to get a direct comparison between these 2 not so different HP's.

And being another one of them tweakers myself, I use a different method to gain access to the innerds of the 800.

I found that the spring was tedious, so I use the method of pulling off the ear cushion and then unscrewing the 2) 8mm torx screws that hold the earcup assembly to the attachment arm.

WAY less fiddly and also opens up the earcup cavity for greater access.
Just a small change in a to way fuss with these remarkable headphones.

Good job and the humor was a great source of laughter for both of us.

AKG was able to increase the bass in the open K7XX by 3dB without increasing the harmonic distortion? Does anyone who has tried both think the HD800S is worth 8X the price of the AKG K7XX? If so why? They measure very similarly.

It looks like the HD800S will fit around even large ears? Are they comfortable?

Torq's picture

The longer I'm involved in this hobby the more I see that measurements don't tell the whole story.

As to whether the HD800S are worth 8x the price of the K7XX ... that's always going to be a personal call. For me it's simply down to enjoying the music more with the HD800S - every aspect of it is improved - sometimes a little, sometimes a lot, but I can't think of anything that's better on the K7XX.

I keep things like the K7XX, Q701 and HD650 around mostly for use with my alternate systems (e.g. my much simpler, smaller, lower powered bed-side rig), and for comparisons.

Are the HD800S "8x better"? No ... but that's the law of diminishing returns for you.

I suspect the bass increase in the K7XX was accomplished by making the pads thinner than those on the Q701/K702.

The HD800/HD800S are the most comfortable headphones I've ever worn. Can barely tell they're there. Very little in the way of clamping pressure and they're pretty light.

zobel's picture

That what I was looking for, a testimonial on the value of the HD800S, and a comparison to something I have. I wasn't serious about 8X better because I realize the actual value is subjective, and relative to ones willingness to invest in incrementally smaller improvements in overall quality. It sounds (no pun) like these HD800S compete very well with costlier cans, Sounds like (again - no pun) I have myself convinced to save up for a pair. I guess after new furniture and floors, these will first on the list. Yep, married. I had heard that pad modification might have improved the bass of the K7XX, and it makes sense that it would without changing the THD in those cans. I also have read that the HD800S are uber comfortable. I lust for them, much more than furniture or flooring. If you are still available, what amp do you like with the Senns?
Thanks again, zobel

Torq's picture

My primary headphone amplifier currently is a Schiit Ragnarok. That wouldn't be my choice for a stock HD800, but with the HD800S it pairs up very nicely.

I also use a Woo WA6, which drives the HD800S fine and sounds very musical, but isn't the last word in authority with those particular cans. Now and again my Chord Mojo has driven the Senns, and that fits quite well also - this is one that I use with the HD800S in some scenarios because I have the Mojo for portable use with other headphones - I wouldn't buy one just to drive the Sennheisers.

I've heard the Decware Taboo Mk III with the HD800 and think that would be a fantastic pairing with the HD800S also.

I have a WA5LE on order ... I'm excited to see how that pairs with the new HD800S.

It's worth noting that I'm a multiple-headphone kind of person. I have the Abyss for some types of listening, the HD800S for others and I nearly bought an HE-1000 a week or so ago (though that's more likely to be an Edition X now).

I could be very happy with any of those headphones as my ONLY pair if I had to be. My choice to have multiple is about genre optimization and even then the differences are signature and stylistic preferences more than good/bad matches.

zobel's picture

Let us know what you think of the WA5LE pushing those HD800DS when you have had a chance to check it out here, please. The only amp of any quality I own is the O2. It pairs well I think with the HD600s, and has plenty of guts to drive my AKG K7XX, but I'm not sure it does those any favors, since they both seem pretty analytical at times (a little on the dry side on top). Straight from any player w/o amp, I like the sealed Sennheiser HD380 Pro, and the Noontec Zoro HD II for on the go. In still get some mileage out of the Senn PX 100 II - with some parametric EQ from my PCDP. (Sony D-NE300). Don't laugh... I can lower the upper bass 4dB, the lower mids 2dB, and bring up the mid treble 2dB, and get good sound from them. Whatever works right? The HD 380 Pro doesn't need or benefit at all from any EQ, IMO.
I'm sure I'm not the only one here who appreciates your reports on the gear you are up with!

Franc's picture

"By selectively adding 2nd harmonic overtones to the low notes, overall bass energy is increased—albeit at a higher frequency than the original tone—and your perception will be a euphonic warming of the bass. "

This is very interesting but I have no clue how to do this. Say you have a sound system that lacks deep bass how do I lift lower frequencies? Do I use some sort of device or software?

Torq's picture

The easiest way to do what you're asking is with an Equalizer. That can be a hardware device, or if you're using a computer as your source (or many Digital Audio Players) it can be done in software. Many software players have Equalization (usually abbreviated to "EQ") capabilities built-in.

Basic hardware EQ is often of the "Graphic Equalizer" variety. You put the box between your source (DAC) and your amplifier, and then move little sliders (potentiometers - variable resistors) up and down to provide a "graphic" (visual) representation of the boost or cut (increase or decrease) for each of the represented frequencies bands. 5-band EQ is common and you can often find more.

Parametric EQ is more powerful and a bit more involved on the hardware side. Software Parametric EQ is incredibly powerful and that's what you'll see in the articles that Tyll and Bob Katz post (they're using DMG's Equilibrium, which works with various audio-player applications). Things like J-River Media Center have parametric EQ capabilities built-in.

Franc's picture

Awesome, thank you for replying. I will have to do some digging to find a standalone equalizer that works on Windows. VST's I do have.

Sorrodje's picture

Hi,

First of all, let me tell you that I'm super proud to be mentionned on Innerfidely. Actually, even for french community, you're the Godfather of personal audio so such a mention for my work is the best reward i can think of.

Actually the story you related is almost 100% true and I had a good laugh when I saw the way you related it. I worked on the mod during a month and my measurements rig was made before the whole adventure though ;)

Happy to see that you share basically the same opinion I wrote about the HD800S I wrote on Head-fi and Tellementnomade.org. To be honest, I didn't hear that much difference in the bass and I definitely think the tamed 6khz is the more noticeable (and welcome) effect. IMO, less 6 khz means we hear more of the whole other frenquencies bass included. Super Interesting thoughts about distorsion though. Very well put.

To be honest, the fact I liked the HD800S so much was the starting point of the "SuperDupont Resonator" and I'm glad you appreciated the result I reached. I let go my HD800S now and I'm perfectly Happy with My HD800SD.

Please just notice that SD Resonator specs are 7mm thick from top to bottom. The felt ring is 5mm thick. Such a...ahum...Big 14mm Resonator wouldn't fit in the 7mm "Hole of Glory".. ahum.... lol.

jussy1254's picture

I own the HD800 and cannot stand the shrill metallic sound. I've actually given up listening to headphones because of this and cannot be bothered to fork out more money for a different pair as I also invested in a hideously expensive 5m cable to go with the HD800. Can anyone please offer me some advice on improving the sound? This is not something I would want to attempt myself so would adore any info/recommendations on a company offering a modding/tuning service. Many thanks

Humbi2's picture

After this article about the HD800S I thought: "Wow. This guy has really trained ears. I could never hear distortion in headphones this good."
So what do you think about the K702. What are its strenghts and weaknesses. Do they have much distortion and a annoying peak in any frequencies. And aren't they way to good for 180€

Dadracer's picture

Hi Tyll
Comprehensive, informative, humorous and insightful. Thank you.
I just wondered if I missed which amp you did your listening tests with please and did you use the headphones balanced?

tony's picture

I loved these 800s the first time I heard them, still do. I wondered what the Germans could do to refine them as I feel them to be the finest Audio transducers (dynamic) in existence.
Sennheiser have never offered up-grade "kits" for any of their products. Leave it up to "our" Tyll to pull back the curtains for us, thank you, who else dared even try?
The HD800 sells for $800 to $1,000 on Ebay, about 10 per month. None of the 800S models have been sold, yet.
Nice video quality : the first one came in a 1080P while the Standard Review version remained at 720P. Color seems very good, frames per second looks higher with depth of field significantly improved, nice work, you're turing into a "Pro".

I used your EQ with my lightly modified HD800 (foam ring and trapezoid) and it had a very pleasing effect.

Hello Kyle,

Many thanks for your continued work/exploration of headphones, their tweaks, and the recent series of articles on the Harmon Target Response curve. Those of use who work in pro-audio/mastering know Bob Katz's work well, and it was interesting to read about his take/tweaks. With regard to the HD800S, would you mind posting a full screen shot of your EQ settings with DMG Equilibrium? I have/use that plugin, and I would like to compare your DMG EQ settings to the curve of the Sonarworks plugin settings for the HD800. While sonarworks has gotten good reviews, (see http://www.soundonsound.com/sos/may15/articles/sonarworks-reference.htm), my experience is that for the HD800, the Sonarworks HD800 setting only seems to sound acceptable with a wet/dry mix of approximately 50%. Users in other forums have posted similar remarks. You might also want to check out the new Waves virtual room plugin, (a free demo for 14 days is available), http://www.waves.com/plugins/nx#introducing-nx-virtual-mix-room
This tries to simulate various rooms in software, and some people think that the combination of an EQ'd headphone curve - together with a room simulation - could give you a better out of head experience with headphones, i.e., like listening in a well calibrated monitoring suite/studio. Keep in mind that Sonarworks does nothing (thus far) with HRTF's - it just does frequency response. And convesely, Waves NX does psychoacoustics together with HRTF (you need to enter your head dimensions for it to work), but nothing with frequency response. Thus in combination, they may complement each other. This begs the question - is a good sounding room the reference (including the listeners HRTF), or simply a more abstract listening environment "in the head" headphones. Happy experimenting.

echoplex's picture

Sorry - I meant to ask you to post a full screen shot of the DMG Equilibrium settings for the HD800 (the HD800s is all there I believe).

Music can have a high cost.

Even Beethoven lost-out from high SPLs.

I had a scary time listening to my local DSO playing Mahler's 2nd. hitting a reported 121db. at my "up-front" seat. The two vocalists, ( posisitioned at the front of the stage) reported, in the live broadcast intermission, the sound being thunderous, I concurred. Steve Guttenberg reported the U2 group hitting 130 db levels.

The Guardian Newspaper is reporting the problems AC/DC are having and the stopping of the group's tour.

So why did I buy the HE1000 partly based on your recommendation that it is a slightly softer, but overall better headphone than the HD800 if suddenly the HD800 is "The Best Headphone In The World?" When you said that in the video I was like "hmmm...."

Tyll Hertsens's picture
...It's simple: I hadn't heard the HD 800 S when I did the HE1000 review. Worry not, the HE1000 is still a marvelously musical headphone, maybe more so than the HD 800 S, but that would be purely a matter of taste.
tony's picture

At some point, you have to accept responsibility.

Still, you accepted the best advice available, you won, you didn't invest in any of the lesser products.

You could've spent $10,000 on the big Stax ( which I owned ) and a Blue Hawaii Amp, a great many folks consider it the best out there.

You did well! the 1000s are one of the top 5 headphones being made today, maybe even top 4.

Tony in Michigan

zobel's picture

Are you thinking about these HD800S, or are you happy with what you have going now? I know you are a Senn guy, just wondered if you are going to go for it with these?

What are your go-to cans now? still using the Shiit Rag?

Is your gov'ner keeping your water clean where you are? No problem here. I should go out now and bust some ice of the creek, and bring in some more water. Were safe, nothing at all upstream, except that pristine high mountain spring. (Just kidding, we have a well).

tony's picture

Sure, I'm a Sennheiser guy, I could be an AKG or Bayer guy, no problem. I've learned from the Automotive NVH ( noise - vibration - harshness ) guys how to "tune" transducer's performance ( which is not at all difficult as our Tyll just discovered from exploring the 800S ). I've also learned from the Audiologists and Dr.Olive ( Harmon ) and Bob Katz that there is no such thing as perfection ( unless you have "Standards" to compare against, as our Bob Katz owns and uses effectively ).

I think that we're left with finding transducers that feature the "singing" voice we enjoy! I love the Sennheiser voice!, they have the Luciano Pavarotti / Joan Sutherland superlatives that sing to me and are cheap ( compared with spending $2,000,$3,000,$5,000 for fresh, sealed boxes of super headphones ).

I've been learning about various 50mm transducers that can perform beautifully but many have housings and hardware bits that obstruct their potential, the Noonteks as an example. So, I looked at headphone transducers as stand-alone devices. I learned that many can sing beautifully.

Headphones has been a curious thing for me, as a business. I discovered Schiit as a useful example of "Internet" based distribution channel systems.

Now, I'm committed to seeing-thru on a Bernie Sanders promise from which I'll turn to Residential LED Lighting systems and perhaps retirement to a Sunny Winter home in Venice Fla. and Spring/Summer/Fall home in Traverse City Mi. I have two older brothers that are anxious to begin a decade of Adventure with me, I'm itching to "have at it", we'll finally get to "See the USA in our Chevrolet", fingers crossed.

Tony in Michigan

ps. I love all the Sennheisers from RS120s thru to the HD800, my RS wireless get the the most milage ( I've tuned them to approach the sound Quality of the HD600). Sennheisers are glorious.

Amp wise I'm an Asgard 2 man, I do own other amps but none I own are as effortlessly smooth, the Asgard 2 is flawless. A possible would be a Tube roller like the Ember from Garage1217 or Lyr or Bottlehead or Valhalla but I like the Rock Solid Performance of the Asgard2 ( I'd have paid $2,500 for it's performance levels and have paid that much but didn't quite get it ). I've paid far more for 2 Channel Amps that were never as musically capable.

Water problems are "all over" the Country nowadays, Flint's lead poisoning is only the beginning of our view of this problem. We as a Nation will be addressing Water Quality in every State. Average American households use 100 gallons of water per day, per person. Grocery Stores can't keep-up with the needs, yet they all seem to have half an aisle devoted to bottled water. We are nearing crisis levels.

zobel's picture

That is a beautiful place Tony. I was there last summer on a trip to my cousins' cabin just south of Suttons Bay on the lake. I was surprised to see all the fruit and wine there, that far north.

Thanks for the gear talk! I too like the wireless Senns. I put 6 CDs in the changer, hit random and go down to work in my little wood shop wearing those RS 175 RF. They really get the most play through the day.

Adventure on! Life is an adventure, not a packaged tour. And keep the music playing.

LiteJazz53's picture

My compliments on a very detailed and informative review, I enjoyed it so much. One of the reasons I chose the newer HD-800S is because of the furnished (4) pin balanced cable. I kept waiting for some comment on any slight differences or improvements, no matter how slight, when using the balanced cable VS the cable with the 1/4" plug. This is one of the reasons I selected the Sennheiser Headphone amplifier, where I could hopefully pull a bit more out of the HD-800S. Is there any sonic improvements when using the balanced cable with the Sennheiser HDVA 600? Hopefully you might tell me there is a tad more low end punch, so what say you??

24bitbob's picture

Where I live, Australia, the difference in price between the HD800 and the HD800S is around A$1,000, that's about US$750. I need to ask myself whether a tweaked HD800, i.e. the HD800S, is worth the A$2599 over and above the HD800's I currently enjoy through my EQ'd laptop source and Luxman headphone amplifier. It looks to me that the answer is a convincing no.

Sennheiser, it seems to me, has missed an opportunity to come up with a convincing and significant improvement (an HD900 model???), and instead are asking customers to fork up large sums of money for a tweak to improve a flaw in their original design. That might sound harsh, but the sums involved are not trivial, and the improvement offered can be equalled and bettered otherwise for much cheaper.

I had nearly convinced myself that the HD800S would be the 'end game' headphone for me. I think I already own it, it's called the HD800.

cpnet's picture

Thanks for the detailed review Tyll. I've been looking for headphones to use as (bedroom) studio monitors, and am looking most closely at the 800 and 800S. For me, accuracy is more important than something that is "pleasurable" to listen to.

The 800 seems to have an accuracy problem at 6 KHz, but I'm not clear which headphone is more accurate when it comes to bass.

A true/pure sine wave should have no harmonics. Are you using an analog device to generate your test tone (and thus imperfect) sine wave, and does that explain the harmonics, or is the rest of your chain that's introducing the distortion (i.e. a tube amp)?

Did you do a frequency analysis comparison of the test tone directly vs. the output measured from each headphone?

The reason I ask is that, the 800S seems to have a flatter response(?) Is it possible that the 800S is more accurate, and the apparent bass clarity of the older 800 headphones is a psycho-acoustic effect due to an (inaccurate) dip around 80Hz? In other words, is it possible that you're not seeing distortion of the original signal in the 800s, but rather a more accurate representation of the incoming signal?

I presume that the 2nd harmonic boost you've seen isn't dynamically adjusting with a change in the fundamental? Rather compared to the 800, there's a fixed area around 80Hz in the 800s that's always louder regardless of the fundamental?

Tyll Hertsens's picture
The AP tester has both digital and analog generated sine waves; both generators are extremely pure.

No, I don't test the tester very often, but when I have it's distortion products are WAY lower than with a headphone in the loop.

I would say the HD 800 S is more accurate than the HD 800 stock. The little dip around 80 Hz is from "pad bounce"---the resonant frequency of the pad bouncing against the side of your head. I've found this to be relatively inaudible.

The HD 800 S just has more second harmonic distortion according to my measurements.

Magick Man's picture

Well, my new HD800S are on the way. Thanks, I guess... ;) I'll compare them to my HD800 and keep the one I prefer.

Babaluma's picture

Which did you prefer and why? Currently trying to decide which to buy...

Magick Man's picture

Overall I prefer the HD800S, they have much better tonal balance. The HD800 treble peak has always bothered me, and it kept me from using them with all types of music, especially if the music is poorly mastered. Now I don't have to worry about that.

Babaluma's picture

Thanks. I've found a few dealers in Paris, so hopefully gonna be able to A/B them with my own lossless flac files and portable player (Fiio X5).

dapost's picture

Hi Tyll, thanks for the great review! Did you measure distortion of the HD800SD? Sorrodje's measurements indicate that the HD800SD has even greater distortion than the HD800S in most of the audioband, including the sub-100Hz region.

http://www.superbestaudiofriends.org/index.php?threads/hd800-french-mod-...

Sorrodje's picture

My Measurements suggest more distorsion indeed but last measurements from Purrin show the same results than Tyll.. I still provide mine cuz I want to be as transparent and honest as I can but if I were you , I'd be more confident in Tyll's and Purrin's than Mine. They're far more experienced and reliable.

My 2 cents.

dapost's picture

Thank you Sorrodje, indeed Purrin's measurements show that your mod does not affect distortion. But I missed Tyll's distortion measurements of the modified HD800. You see, I need to decide in the next few days which one of the two versions to buy new. I think I will go for the original HD800 cause of the distortion issue.

dapost's picture

Apologies, Tyll has indeed measured distrortion of the HD800SD - it's all in the pdf.

Hi How does this compare to HD700 in the highs

hapnermw's picture

Hi Tyll, Thanks for doing the lord's work for the headphone community. On the issue of EQ, I know you are aware of its phase, etc. issues when done in the analog domain. Have you done any analysis of your use of JRiver/EQuilibrium vs the use of high end DACs. The primary issue is that I would expect similar phase issues with this digital EQ. For instance, I'm using a Schiit YGGDRASIL DAC, if this isn't fed the exact recorded bits, it's value is mostly lost. I would expect that JR/EQ uses the typical Parks-McClellan FIR algorithms that have been responsible for compromised redbook playback for years. Trading a bit more HD800 base for the pre-ringing and the other compromised phase accuracy this results in doesn't seem to be a good tradeoff. What say you ...

how does this compare to the ether/ether c in terms of tonality and technicality?

which one is warmest and which one is closest to neutral?

I intend to use them to listen to mainly metal music and other genres are second, which will suit me best?

Thx!

Babaluma's picture

Which to buy? They will be used mainly for pleasure listening, but also sometimes for audio restoration work and mastering. I currently use HD600. Will 800 or 800S both be a huge step up? Have read both of your excellent revbiews, but am still undecided! Anyone know a shop in Paris that has both I could try, with my Fiio X5?

Hello Tyll,

At this time i have got the akg k712, and i want to step up my headphone game.
at this point i consider the Focal elear, the mr. speakers ether and the hd 800/800S.
i have got a eq system. But i do not want to modify my headphones.
In this video you say that the hd800 with mod and eq is superior to the hd800S.
I wonder if it is still true without a mod. and overall witch headphone you enjoy the most.
Thank you very much.

Pretty Good Pair Of Headphones !

When I first received my HD800s, I too thought them thin and too bright. I recabled with a Norne Draug and put about 200 hours on them. They have mellowed out and become much warmer with a beautiful treble. With their detail I'm enjoying them more than I ever thought I could enjoy a set of headphones. Still think they are the World's Best Dynamic Headphone.
