Having already purchased the King Pro, I would love to try the Secret Garden as it uses the same type of driver, albeit slightly larger than the Kings' 10mm. If there is any sonic improvement here, I suspect its going from "spectacular" to "super-spectacular". I find the Kings' sonic performance deeply satisfying on all points, and would expect more of the same in the Secret Garden version. I am super-curious about how much better the fit and feel is, as my main problems with the King Pro have been fit and eartip seal related (still struggling with finding the best eartips to use). If these earphones provide sonic performance at least as good or better than the King Pro's, that alone IMO would justify the price easily. Add in a potential improvement in fit consistency and comfort and we have an item with a nearly irresistible value to any serious audio enthusiast. I'm in a position where I'd like to try these, but if you are in a position to buy these, my guess is that you'll not be disappointed.
