Ask Nomax The Prophet.

The answer is more PR than technical, don't bother. :evil:

I've been told last year that Sennheiser has a new flagship in the works, not sure if it's an electrostat or not.

10. Planar-dynamischer elektroakustischer Wandler, mit

einem durch mindestens ein 2K-Pulver-Spritzgießverfahren hergestelltem und entbinderten Magnetsystem.

 

Die Erfindung betrifft ebenfalls einen planar-dynamischen elektroakustischen Wandler mit einer ersten und zweiten Trägerplatte sowie einer Membran und einem Ring zwischen der ersten und zweiten Trägerplatte. An der ersten und zweiten Trägerplatte sind eine Mehrzahl von (beispielsweise quaderförmigen) Magneten vorgesehen. Gemäß der Erfindung können die Magnete zusammen mit nicht magnetisierten Teilen als ein Magnetsys-tem des Wandlers durch ein 2K-Pulver-Spritzgießverfahren einstückig hergestellt werden.

I'm personally guessing sometime later this year or next year. If it really is an planar like the diagram and text suggests I'm quite intrigued, the electrostat Senns I heard were amazing I'm curious what Senn would do with a planar. I know my friend will get her hands on it as soon as possible when it comes out.

Wow, this is pretty big news. This is always a problem for early adopters. Still, it's exciting to see the bar being raised, hopefully to new levels.

I'm just guessing on the date and since there has been talk of it recently it's probably not too far away, I do trust the info that something is in the works. Hopefully it competes with the SR-009 while being a fair amount cheaper. Other than the SR-009 I haven't heard anything I consider truly on par in terms of overall refinement with the old legendary ubers the Orpheus and the R10.

That drawing and description hints at some manufacturing process and not about an actual product. "Just" a process that involves the manufacturing of headphones with different driver technologies. Nobody does R&D like Sennheiser, I'm pretty sure they're experimenting with planar since quite some time but this here is not it. 

 

Their new ES will cost quite some money, I'm pretty sure the SR-009 will be a bargain in comparison. :evil:

Nothing really has been officially confirmed or announced, so I'm not going to get too worked up about it. I'm sure Sennhesier will roll out the marketing when it's time.

 

I took delivery of my K812 yesterday. A big thank you to Brian @ RazorDog for expediting the shipping for free on my replacement pair. Honestly, he had me pestering him for like three weeks and he put up with me very well. Good man.

 

This one is perfectly constructed without any flaws and the sound is superb. Initially right out of the box it did sound a little dark/veiled, more so than my initial reaction to my first pair. I shrugged and threw it into my burn-in chamber (guest bedroom) and about eight hours later I went to go check on them for 15 minutes. This 15 min session turned into a 2.5 hour session at the end which my wife had to come to the guest room to come get me because it was past 1am "What are you doing?" she asked and when I tried to explain the amazing K812 she rolled her eyes. :rolleyes: Haha. (Typical behavior from the inferior sex which does not have the capacity to appreciate greatness :evil: [I said this in my mind of course so that I would not be killed])

 

For me personally (to my ears!!!):

 

So again, the K812 is super well balanced, there is no area of the frequency response that sticks out as too much or too little. Right amount of bass, mids, treble and everything inbetween. Not to say it's the end word in being linear though, just nothing offensive or lacking.

 

Harsh upper-mids? I don't hear it. No it's not even 1% harsh. I would say the LCD-2/HE-500 has harsher upper-mids/lower treble response, more ragged, even though they are more shelved down in general.

 

Distortion? I don't hear it. No not even the slightest on any recording in any genre on dozens and dozens of songs.

 

Ringing? Nope. Really? Nope.

 

All I hear is incredible clairty, detail, and the most balanced sound this side of the Focal Spirit Pro (not quite as neutral, but man it's close enough, closer than any other headphone I've tried other than the HD600)

 

*One weakness I observed was that the K812 isn't the most coherent headphone, this along with the dynamic slam factor is probably the two weakness I perceived. It is better than average in these two areas, but not really flagship level. It has great speed/attack, but is also not the most focused sounding either. It's "okay" in these areas, but nothing to write home about.

 

So I guess the perfect headphone for me personally needed to have confused/tizzy treble, ragged impulse response, terrible looking 30 hertz and and even worse looking 300 hertz squarewave response, crazy amount of distortion, 2nd, 3rd, and 4th order distortion too, blatant and painful ringing, and a walk of shame rating from Tyll and the Pirates.

 

No wonder it was so hard to find! It's difficult to engineer something this obviously bad. Thanks AKG for making a terrible headphone. I love it because I'm obviously deaf and retarded!

Welcome back. Can you describe exactly what you mean by lacks coherence?

I made the mistake of trying to connect it to an AV-ampliefier and wondered what happened to the clarity, lower register, etc. Sennheiser HD800 had also these effects but to a much lesser degree, with the K812 Pro it felt like it was a totally different (worse) headphone.

heard ya the first time. you saw the specs right? fact is it's an efficient can that's easy to drive. but if you think it needs a kilobuck head amp to get the most out of it then you've come to the right place coz this is the high end. wink.gif

maybe/maybe not. if this really is a pro audio can then it's designed to plug into various recording consoles and playback gear. pair it with an astell&kern dap and you're good to go. that's what the guys were pushing where i tried it.
