Today! Sorry for the delay on that one
Has the interview been released yet?
Dellwolf
No, not yet. We are still working on it and it should be out soon. We'll give you an update once it's published.
Is this still going on, haven't seen any replies so far. Did I just missed out? The big question I wanted to know if Sennheiser is working on new flagships after HD800S?

Hopefully, the price is under $2000

pls, dying to find out
A pleasure to speak with you Axel. Will Sennheiser endeavour to engineer wireless in-ear headphones that are also waterproof? I know from a marketing point of view these are all the rage right now, but if they are on the cards, now is the right time! Also, considering that fashion is considered more often in headphone purchases these days, is it possible that Sennheiser could produce a sleek, colourful version of the Momentum 2.0, perhaps with the strength of stainless, and with the colour scheme inclusive of Sony and Beats? Again, this is really from a marketing point of view. Thanks very much for your time!
are there any plans to release a new flagship after the hd800 not counting the orpheus?
Tyll Hertsens wrote a glowing review of your HD 202 headphones. Do you have new models coming in the under $100 segment? Your warranty is impressive and nearly unique in the headphone marketplace. Suggest you include a replaceable cord option in this price range, as Monoprice does.
What are your thoughts on the "Sennheiser veil" that has been the object of many an argument on the internet? Is it a desired effect? Is it an artifact of tuning out something worse? Or is it, as many have claimed, not really there?
Heefty
HI . In 2003 I bought the Sennheiser HD 650 when it came out. I was a big fan of Sennheiser. To be honest I simply "hate" my purchase and regret it. Veil sound awful bass even with a proper headphone amplifier. Also the paint on the headband cracked. I discover Grado at that time SR 325is and love the clarity detail fast bass that was not present in my HD 650. But I continue by the years to read reviews about the HD 650 and absolutely don't understand those positive reviews. So one day (last summer) I stop at a dealer place to try again the Sennheiser HD 650 and I immediately notice that it was much lighter. I borrow it for a weekend and as I discover it has nothing in common with my 2003 version. Bass was faster and you know what ??? no more veil sound. Detail clarity appears also. So it seems clearly that this headphone was improved. My understanding is the veil problem is part of the first years of production. So did you saw the criticism about the veil problem ??? and react by correcting those flaws. By now I used my 2003 for video and my recent purchase for music. The color of the drivers on my 2003 are white the new version is grey (kind of stainless steel color). The actual version is a wonderful headphone. I can live with this one alone. Like to hear your explanation. The veil story of the HD 650 need to be clarified now by Sennheiser.
In theory, part of the reason enthusiast products are important and necessary is to fund development of technology that will inevitably trickle down to less costly consumer products making them better than their predecessors where. There it can and probably does make the manufacturer more money over the long run.
Can you give any examples from your experience of this happening? Are there any specific design points from the legendary HD 580/600/650 series that have found their way into other Sennheiser designs during the decade or two of their lifetime you can speak to?
Dear Herr Grell,
The original Sennheiser Momentum was a fantastic headphone and in my opinion nudged the headphone design trajectory towards a more mature design note in both shape, function and perhaps foremost in terms of materials. The leather on steel with a somewhat understated design really appeals to me, much in the same way as the B&B P5s did a few years ago and more recently the P7s. The momentums was the first pair of headphones, other than the B&B P5, that could be worn with the business uniform. Walking around an airport with a pair of Audio technica M50s was never an alternative for me. Today there is a slew of alterantives for the business traveller and casual everyday fashionado. My one big gripe with the momentums was the fit, for my ears the cups were to small to be over-ear and as a pair of on-ear they did not really work. The half on half off design confused me and I wanted to take this oportunity to ask if this was a conscious decision in the design process? Did the design restrict the comfort process in this case? A followup to this question would be if Herr Grell thinks that a focus on design usualy leads to sacrifices, comfort or soundquality generally seems to take a hit as soon as the look and feel of a headphone takes presence.
I also wanted to ask a few questions about wireless headphones, this is a hot topic at my workplace. Many consider the ease and simplicity of Bluetooth headphones and earbuds to benefit the listening experience to the degree that the loss of soundquality is negligible. I strongly disagree, I use a portable DAC with my smartphone and a stationary DAC at my desk at work. I prefer vinyl or high quality files such as ALAC or FLAC and there is no doubt that using such devices and such files lead to a different (to avoid the word better) listening experience. Now to my question... In this age of streamed media, noise-cancelling headphones and cordless equipment where do you see the market leaning. Is the market size of people who prefer "low quality sound with ease of use" big enough to bump "cordlovers" to a nisch? I fear for the future of sound when the average end-user is unable to experience the sound upon wish a technician and artist spent many hours, resources and money. Could you put my mind at ease? :-)
Will there be another Momentum style headphones with an over-ear design and a, I would like to call it, less mature sound? I listen to a range of genres and prefer a headphone like the V-Moda M100  (or LP) that is able to hit a sweetspot where many genres sound perfect.

Great questions. One of them is easy to answer though.
Cord lovers have been a niche market for a long time. The majority of people easily value the convenience over quality in general and that does extend to headphones. See Apple's recent decision to nix the 3.5mm jack from their most recent phones for example. See the shitty white earbuds/earphones people have been listening to since the iPod became a thing for another. See how awful highly compressed audio sounds and yet it's completely taken over to the degree that I have a hard time finding hard copies of CDs for some groups to rip to my own FLACs.
It's not hard to see where the market is going. It's sad that so many people don't even know what they're missing out on when they don't hear what the musicians/engineers worked so hard to make sure was in their favorite music.
It does provide fun experiences for those of us who have actually done the leg work and started down the rabbit hole though. I always love the shocked expressions I get when I take someone's shit earbuds or beloved beats or skullcandies away and sit them down to hear my rig playing their favorite song. That open mouthed WTF look is priceless.
When is Senn going to develop new hi-fi headphones and replace the lackluster HD800? When are they going to design new mid-fi headphones to replace the ancient and also lackluster HD600?
Will there ever be automatic digital "room corrrection" equalization for headphones? Especially in ear monitors.
2 way dual driver in ear monitors are common. Will that trend transfer too full size headphones?
Can you finance an Orpheus System?
giff hd 666 priced at 200$ that smokes 540/580 versions and k501/240df. stop making hd800 or orpheus price point stuff tyvm
What is the reasoning for the significant frequency response differences between the HD600/650 and the 700/800? Especially considering these are more than a decade apart.
Do you think there should be an expectation that professionals/audiophiles should equalize their headphones?
What is your opinion on the research done by Sean Olive at Harman on a preferred listening target curve? HD650 seems to do a very good job of matching it except for the bass response.
Is the differences in perception surrounding open/closed back headphones simply as a result of noise attenuation.
Hi Axel great to talk to you! I promote Sennheiser headphones here in Australia, and am elated to be able to speak to you in any forum. My Question: Considering open backs are in a class of they're own, and should be used in quiet environments to appreciate them, is there any equivalent to the HD650's or HD800's that will be engineered in the closed back form? It would be nice to take them out to other environments, such as parks, trains, cafe's, University campus etc. without annoying city sounds or abrupt sounds that might jolt the listener. Thanks for your reply!
Any chance of Massdrop HD7XX or HD8XX please?
Any plans in designing a ear pad for people that wear eyeglasses like you do? Replaced 3 pairs of ear pads on my HD555 now because the feet of the eyeglasses keep pushing the point where the pad lining is glued on the foam of the pad so they keep splitting. Same design for earpads are used by most of Sennheiser headphones with only minor variations.
What do you believe is the most underrated or too oft ignored quality of headphones in general and how do you believe you've consistently accounted for it in your own work?
When will Sennheiser come out with a new flagship headphone that will compete against the Hifiman he1000, Audeze LCD-4,StaxSR009 , and Focal Utopia? Will the new Sennheiser high-end flagship be priced under $2000?
1-Why hasn't Sennheiser made and Will there ever be a high-end closed-back headphones on the level of the HD800's? 2-Will Sennheiser jump on the planar bandwagon ?
Ayy, hit Massdrop up with some HD2xx's?
We want some info about HDVD 800 successor. Any ETA? It has been over an year since Axel showed us the prototype and after that nothing.....
When will Sennheiser release the successor to the HDVD 800? The prototype was first shown by Axel Grell at the Fujya Avic Headphone Festival in October 2015 but they still have not released it.

Really would like to know answer to this.
How a guy like Alex Grell looks after his ears while working with headphones all the time. Also how did they come up with all the crazy ideas about HD800
What does your personal audio setup look like?
When did you discover your love for music and audio? What was your first musical love?
Would you consider an upgrade program for owners of the HD800 to trade-in for the HD800S?
Can you pleeeese make a ton more of the 6XX I'm so keen to buy a pair.
What was the inspiration and passion behind the HD 600, 650, 700 etc? Cheers, Richard.
