I would ask whether they tested, and with what methods, the HD800 for its soundstages Accuracy. Certainly they made it wide, but are sounds being psychologically perceived where they should be if it was in the real world, or are their location being distorted? Not a negative review, just stating that I am searching for the ideal soundstage and determined some basic methodology for testing its accuracy and found issues with their lower tier imaging oriented headphones. I would like to know whether the HD800 addresses that.

Dear Axel, I love listening to classical music and I feel like most modern headphones are designed for contemporary music with focus on specific bass, mids and transients. Is this true? What is Sennheiser’s take on it? I have HD6XX and I love how classical music sounds with them. I use Focusrite Scarlett Solo on 192kHz/24bt/1024sr in a chain with Creative X3 (DAC famous for it signal processor).

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

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!

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.
