Product Description

From the Manufacturer

The Story of the Sennheiser HD800

The story of the Sennheiser HD 800 began with a dream: of developing headphones that go way beyond conventional equipment to become music phones, or even perfect sound phones. The dream of creating a hi-fi device that sounds as brilliant, clear, and undistorted as if you were sitting right next to the source. The dream of creating an acoustic experience more incredible than anything ever heard through dynamic headphones: in spheres that no other category is capable of reaching--right there where perfection begins.

We couldn’t go beyond physical boundaries--but we did cross the boundaries of thought. The HD 800 is equipped with a completely new transducer and only the very finest of materials have been installed: each part carefully inserted by hand. We are talking about manufacture in the truest sense of the word, right from the initial drafts to individual handcrafting "made in Germany".

Above all, the Sennheiser HD 800 truly personifies the creative force of the company that created it: by displaying the passion for perfect sound that has been driving Sennheiser innovation over 60 years.

The Principle of Spatial Listening

The impression of spatial listening is created by a minute time lapse with which one and the same sound wave arrives at the inner ear. Ideally, the sound waves produced by a hi-fi sound system reach the listener at an angle of 60 degrees. The sound waves do not reach the ear straight on, but through a slightly angled sound front. This causes some of the sound impulses to reach the nerve ends of the inner ear earlier than others. The resulting time lapse is a matter of split seconds, but it is exactly this phenomenon that gives the impression of spatial listening.

Wearing the HD 800 you enjoy much more than just a sound experience of out-standing brilliance. You experience a form of spatial listening never heard before. You have the feeling of being in a studio together with Thelonius Monk or actually being present at a rehearsal of the Berlin Philharmonic. The HD 800 makes spatial listening possible through a combination of the large transducer surface and the angle at which it is suspended. The slightly angled sound front effectively simulates the principle of the spatial sound experience. No other manufacturer comes as close to producing a natural sound experience as Sennheiser with the HD 800.

Outstanding Technology Provides Outstanding Sound

The lightweight ring transducer precisely delivers sound without harmonic distortion

The superiority of the HD 800 is based on a completely new principle, right at its very heart: The transducer is designed in the shape of a ring. Basically, the larger the surface of the transducer the purer the sound—particularly when it comes to the low notes. A large surface area, however, also generates disruptive spurious oscillation at higher frequencies, so-called eigenmodes. This is primarily due to the fact that conventional-sized transducers do not have a satisfactory way of controlling high-frequency oscillations. The ringed shape of the new transducer effectively solves this dilemma: Its broad area oscillates in an extremely controlled way due to the large coil and the two supporting surfaces. This results in a previously unheard-of degree of freedom from distortion and thus the greatest purity and brilliance of sound.

And when it comes to the naked technical facts, the HD 800 doesn’t save on superlatives: The 56-mm-wide transducer is the largest of its type. The same goes for the aluminum coil (40 mm) and the 42-mm magnet system.

Ring Transducer vs. a Conventional Transducer

In contrast to a full-sized transducer, the ring-shaped transducer utilized in the HD 800 greatly enhances the control of the oscillating surface. This results in a more voluminous sound wave and thus far greater clarity.

In a conventional transducer, unwanted spurious oscillation can occur due to eigenmodes. Even improvements such as increasingly sophisticated Duofol laminations are unable to completely negate these physical limitations.

At the heart of the HD 800 is the patent-pending ring-shaped transducer. The wound precision wire that makes up the coil is only 42 micrometers thick. It consists of 3.5 layers of wire in a total of 98 windings. The space between the two magnets, in which the coil oscillates freely, is only 0.6 mm wide. The work of fitting these parts is done by hand—and the same thing applies to many of the other components of the HD 800. The transducer of the HD 800 transmits in a frequency band from 8 Hz–50 kHz. Not that anyone is capable of perceiving this sound range, but the pleasant ancillary effect is that the transducer delivers an extremely clean sound in the 16 Hz–20 kHz range.

Cords and Connections

The symmetrical cords are designed with twin-core, high-performance, Teflon-insulated connections on each side. They are additionally covered with high-quality material for better shielding from oscillations caused by ambient noise. The jacks are exclusively produced for the HD 800 in Switzerland and feature gold-plated bunches. Gold has the highly positive property of having a very low transfer resistance, thus guaranteeing excellent contact without interference.

Headband and Mountings

The headband consists of a sandwich design in which a metal layer is covered with several layers of plastic. The high-tech plastic possesses incredible attenuation characteristics and ensures that oscillations are not transmitted to the headphone mountings.

The headphones of the HD 800 are only mounted on one side, to make sure they fit optimally over the ear. The relocation of their point of balance towards the back of the head also enhances comfort for the wearer.

A special kind of Japanese Alcantara has been selected for the ear pads. This material is extremely comfortable to wear and easy to maintain. Leona, an ultra-light, high-rigidity special plastic, is as hard as titanium and thus yielding extremely low oscillation. Hi-tech stainless steel mesh--the ideal material for three-dimensional sound--combines all the properties of stainless steel with an incredible degree of transparency.

This review is from: Sennheiser HD800 Over-Ear Circum-Aural Dynamic Premiere Headphone (Electronics)

I am not a golden ear audiophile. I don't know what it means to hear "the air between the strings" and other such audiophile descriptions. More power to those that can -- I am simply not able to do so. I do however know that music is and always has been my greatest entertainment, and that as I have grown older, my ability to pay higher dollar for my equipment has also grown. No way could I have had these headphones in past times. No way could I have justified their cost. Other priorities would have always taken precedence over these. But now that I can afford them, I still debated and agonized over the cost, but in the end decided I would go for them. Am I glad? Absolutely. They are without question the best sounding headphones I have ever heard. I could hear the difference straight out of the box, I did not even do "A to B" comparisons to know how good they sounded. I did do comparisons with my HD600 to HS650 upgrade and was never sure I heard much difference. Not so with the HD800s.

Here is the best way I can describe them. When I was young, I would listen to a lot of music particularly nice in headphones. I am talking Yes, King Crimson, Pink Floyd and many others. I am a child of the 60's/70's so I would often be a bit "altered' while listening. In those days a pair of Koss headphones, a little "substance", and the latest King Crimson album would lend to a headphone experience whereby I would believe I was literally dreaming the music. (A very nice state). But as time went on, the subtances went away, the latest King Crimson album I had in mind (Larks Tounge in Aspic) is almost 40 years old now, and my hearing ain't what it used to be.

All that was said to lead up to this. With these headphones on (no substances), I am dreaming the music again. The above mentioned artists, and now with music such as Chick Corea and Miles Davis thrown in the mix, sounds like they are in and around my head like they have not been in those 40 gone by years.

I would conclude that these headphones are worth the cost if you are in a position to put out that kind of money AND you really love your music. But be warned --- once you hear these, there's no going back to lesser headphones.

5.0 out of 5 stars Headphone Nirvana!, August 1, 2009

By 

D. Macnaughtan (Polmont, Stirlingshire Scotland) - See all my reviews

This review is from: Sennheiser HD800 Over-Ear Circum-Aural Dynamic Premiere Headphone (Electronics)

I believe I am the very first person to have the pleasure of owning these phones in the UK (Scotland). They are not available yet via Amaxon UK, hence my review on this site. It took 10 weeks of very considerable pressure (via my good friend Mark, at HiFi Corner in Falkirk!) to persuade the powers that be in Sennheiser to ship me a set. These finally arrived on Friday 24th July. All HD800's are uniquely set up and have their own serial number engraved on the head band (mine is 01327). The come in sumptuous packaging!

To get the best out of these phones, you are well advised to invest in a serious headphone amp (I use the Lehmann Black Cube Audio) and some decent interconnects (Chord Anthem 2) to whatever your source is (Sony CDP - 3100 broadcast player). The sky's the limit to the kit you can connect. These phones will not win you friends on the bus or plane - they are open-backed, so very noisy. You need to get away from the world! These are man-size phones. They touch no part of your ear and have just the right pressure on your skull. You can wear them for hours and forget you have them on. You also need to burn them in for at least 100 hours (although they are great, straight out the box). So far, so good!

I have a long history with Sennheiser phones, having worked my way up through HD 25 and HD 650's. Having read all the rave reviews from you lucky people in Obamaland, I was at a loss as to what to expect when I had my first listen. Having been used to very high quality reproduction from the 650's, it was difficult to see where we would go next.

I decided to auditiond a track from a carefully chosen disc on the 650's (Verdi Requiem - Robert Shaw and the Atlanta Symphony), then play it again on the 800's. Very first impression was surprise at how little difference there seemed to be. I tried various favourite tracks and the picture started to become clear.

The difference with the 800's is much more subtle but significant. You only really notice it big time, when you go back to the 650's and appreciate how two-dimensional they are, against the 800's. After an hour or two (and you just want more!), I would sum up the difference - with the 650's you listen to the music while with the 800's you're part of the performance. Nothing is spectacular - everything is natural and real. There is no distortion, no matter what you throw at it. This is honest reproduction. They make bad recordings sound bad and bring out the very best in the stars of your collection. Recordings that you know better than your wife, will suddenly have added elements. Others that you pass by (you know, all these ones on the shelf that you never listen to?), they suddenly come to life. There are not enough hours in the day - you have to sleep sometime!

These phones are for the long haul. They will just get better, the more you play. There is no fear here. You suddenly realise that for years you have been making allowances for bits of recordings that previous kit could not quite handle. These phones are a match for everything in your collection. Be careful with the volume nob - your ears will bleed before these phones struggle!

It is early days yet and I still have so much more listening to do. In 10 years, when Sennheiser release the new HD1000's, I shall no doubt be at the head of the queue. It is difficult to imagine what they can seriously improve - but we've been saying that for 100 years! I suppose we're down to fractions of one percent now.

Should you buy these phones? If you really love your music, you owe it to yourself. If you have been using mediocur kit and want to really hear was recorded at that concert or in that studio - now's your chance. If you want to walk down the street with these plugged into your iPod (you'll need an adaptor!) you've got more money than sense! Yes, it's a big investment (not to mention the kit you really need to appreciate them) but the end result can take you places you never knew existed!

Go for it - and tell me how you got on!

Happy listening

5.0 out of 5 stars Effortless, powerful, and supremely musical; one of the best!, June 7, 2009

This review is from: Sennheiser HD800 Over-Ear Circum-Aural Dynamic Premiere Headphone (Electronics)

SHORT VERSION:
The Sennheiser HD800 sets a new metric against which every other serious headphone or transducer must be judged. I've heard too many "breakthroughs" that just couldn't deliver the goods. This product is different.

It's hard to describe a piece of gear which, upon first listen, sounds different than anything you've heard, yet sounds so completely effortless and musical that you're left with the singular impression that the previous way you've listened to music is somehow incomplete, a wrong path if you will, and that this is clearly a better way.

I can't imagine anyone buying these and not being thrilled. They are a rare product indeed -- one that adds a significant new dimension to recordings you may have owned for years and thought you knew.

LONG-WINDED VERSION:
First some background. Music is very important to me; I played the cello for many years, currently sing in a gospel choir, and now do my own audio recordings of choirs and other groups. I spend a lot of time with these tracks, during both the editing process and for my own personal benefit. I often pore over recordings to try and learn the nuance and details of each part.

In this regard my playback system is crucial. I record using a Sony PCM-D50 with a variety of microphones, my favorite being a RODE NT4. I edit these on my Mac and use a Grace m902 for D/A conversion and to drive my headphones. I switch back and forth between AKG K701 headphones (now replaced by the HD800) and a pair of GURU QM10 nearfield studio monitors. With that out of the way let's get to the heart of the matter...

The HD800 is beautifully designed and artfully executed in regard to materials and construction; these headphones are beautiful to look at and handle and are supremely comfortable to wear.

As to performance? The Sennheiser HD800 sets a new metric against which every other serious headphone or transducer must be judged. I'm sorry if that sounds like so much hot air, but I honestly didn't expect to be so impressed -- especially out of the box with no break-in. I've heard too many "breakthroughs" that just couldn't deliver the goods. This product is different.

It's hard to describe a piece of gear which, upon first listen, sounds different than anything you've heard, yet sounds so completely effortless and musical that you're left with the singular impression that the previous way you've listened to music is somehow incomplete, a wrong path if you will, and that this is clearly a better way.

I won't get into the finer points of tonal balance, sound-staging, imaging, or brightness/darkness. All I can say that these headphones are very natural in regards to spatial presentation, in a way that I find entrancing. Their response is smooth and well-balanced at both extremes. I don't know what else to add, besides the fact that they are reproducing music more naturally and effortlessly than any one piece of gear I've added to my system over the past decade.

A great example of what the Sennheisers contribute to my system comes when listening to recordings of the human voice:

ARETHA - LIVE AT FILLMORE WEST on MFSL:
Track 9 "Spirit in the Dark" with Ray Charles
Aretha is in such total control of her voice that she (rather infamously) never sings a song the same way twice -- she is completely improvisational depending on how the spirit moves her.

Listening through the Sennheiser HD800 gave me a far greater sense of what this recording actually sounds like. Previously, I'd been disappointed by the quality of this recording. After hearing it anew via the HD800 I am ready to admit that, despite the blemishes, this recording now has a sound that matches what must have been one massively impressive musical experience. The performance was always there, it's just that now I can hear a new level of detail that was lost.

On this particular song the patter between Aretha and Ray Charles is very cleanly revealed and every nuance is easily distinguished. Each microphone buzz, every shout-out from the crowd, and every detail is now very clearly revealed. However, none of this is to the detriment of the music; to the contrary, it makes the performance that much more complete. It's not as though these things are exposed or laid bare; the fact they are rendered so accurately just seems to add to the fullness and emotional impact of the event.

Bass lines are also very clearly revealed when listening through the Sennheisers; in this respect the AKG K701 is simply out of its' league. The HD800's bass is in NO way emphasized, but it is clear, fast, and a constant force that propels the music.

It's wonderful to hear Aretha's soulful sense of time, of which she is the undisputed master -- she can delay a beat, twist a phrase and bend time, yet once you think she's lost she always brings it back (often at the last instant) in perfect sync. Her rendition of "Bridge Over Troubled Water" is an amazing example of this. This particular song has particularly complex vocals on her part, where time gets compressed and she squeezes a lot of syllables in very quickly, to catch the beat at the end of a line or phrase. On most every system I've listened to this recording on, you simply have a difficult time distinguishing every nuance of her phrasing and modulation. Listening through the HD800, you wonder how you never caught these details before.

GO TELL IT ON THE MOUNTAIN by THE BLIND BOYS OF ALABAMA:
Track 1, "Last Month of the Year"
If you sing this type of music you spend a lot of time trying to clearly hear each vocal part; this is part of a tradition in Gospel music where learning is often by hearing, rote, and repetition. The HD800 has tremendous resolving power in this regard; never before have I been able to distinguish each of the seven members' voices so clearly.

Additionally, at the very end of this track there is some interesting modulation from the electronic organ on the last 18 seconds of the cut; I've never heard this so clearly rendered from beginning to end.

CHILL OUT by JOHN LEE HOOKER:
Track 6, "Tupelo"
Track 6, "Tupelo"
On this track you can clearly hear John's toe-tapping and how it resonates and decays in the studio space. His guitar is beautifully rendered, yet his more aggressive playing never sounds as edgy as with most systems. His humming is clear whether he is doing it loudly or softly. He talks a lot of this song, and I've never heard his voice sound as clear and full.

Track 8, "Annie Mae"
The piano on this track is conveyed better than I've ever heard it before. Listen for John's brief conversation with the pianist at the end of the track; it gives you a great sense of the resonance of the studio and, through the HD800, it's easy to believe you are right there with them.

MY OWN RECORDINGS:
I've also been astonished to hear things on my own recordings (mostly of choirs and vocal groups) that were buried just beneath the surface, things that I didn't fully grasp were there. Subtle sounds from the crowd, a soft whoosh from a ventilation system, the rustle of papers or sound of remote footfalls -- it's all there. Since I have spent many hours editing and polishing these tracks, this struck me as a significant surprise. To hear something on one of your own recordings that you'd never heard clearly before -- that says it all to me. The HD800 is the Hubble Telescope of the audio world when it comes to clarity and resolving power.

One thing is important in this regard. Many products are ruthless when it comes to how they lay bare whatever is on a recording. Many times this leads to the "garbage in, garbage out" conclusion, where we assume that a poor recording alone must be the obvious reason that something sounds the way it does.

Somehow the Sennheisers have both superb resolution, excellent and extended response, AND a wonderful sense of sweetness and "rightness" that isn't explained by charts and specifications. Do terrible recordings still sound that way on HD800? Yes, to a degree, but here's what distinguishes the sound of these headphones. I believe the Sennheisers are pulling more details and artifacts out of bad recordings, and that this adds a depth that makes these recordings more pleasing to listen to. It's not because of any euphonic colorations or something the HD800 is adding to the music.

One more thing anyone considering these headphones should know; it is critical to have a great headphone amp if you are going to get the best out of this product. Comparing the Sennheisers to my AKG K701s (with each driven by my Grace m902), the HD800 requires roughly 20% more gain on the volume pot to reach the same level. The Grace m902 never runs out of steam or sounds as though it's not up to the task, but I can't say anything regarding how these headphones might sound on lesser equipment.

So, with that one caveat, I can't imagine anyone buying these and not being thrilled. They are a rare product indeed -- one that adds a significant new dimension to recordings you may have owned for years and thought you knew. I can't find anything to complain about yet. I have a big head and rather large ears and can't wear my AKG K701 for more than an hour without feeling some discomfort. While writing this I've been listening to the HD800 for nearly four hours, with only a brief break in the middle (a guy has to eat, after all). There is no trace of pain or fatigue; these are, without a doubt, the most comfortable cans I've... Read more ›
