Yeah, it's too bad. They could've have made a friendlier design and they would've been the best IEMs ever. I'll see myself out.
DK-4001 is Zirconium alloy housing with smooth shap and lighter weight, it would fits most of people's ear canal
So I found out from Andy at DUNU (oddly enough, while most people on here know of Vivian, I've never corresponded with her!) that the DK-4001 housings are actually smaller in size than those on the DK-3001, and I guess because of the Zr liquid metal alloy, they can make smoother curves to the shapes, which is why the render of the concha side of the DK-4001 looks smoother. I don't know how much it'll translate into superior comfort for @papa_mia specifically, though. You may still have to try out a demo unit somewhere in order to find out.
Still awaiting details for the other questions. @DUNU-Topsound any indication of how much they'll be retailing for and when they'll be slated for release? I think the latest I've seen on Chinese boards is 5999 RMB; I believe that's an all inclusive price, so my guess the US/EUR price will be $799 / 700€, plus sales tax and VAT or whatever else applies.
Will post more information when I get it.
