They look really nice, could've been better if they had detachable cable, it'd really suck if an earphone this expensive breaks because of the cable.
As you are the only person I know that owns a pair of these, you need to give us more information on how it sounds, a review would be even better! :D
Yeah, the cable isn't detachable which is a shame. Because the IX's case is made from stainless steel it's fairly weighty compared to every other IEM I've owned so far, so there's a chance if I'm not careful I might damage the cable if I hold it by the cable. It is nicely braided and not stiff which makes the IX easy to curl up and store. The cable also seems to tangle-resistant too.
I don't mind attempting to write a bit more on how it sounds but my vocab around describing sound is a bit limited so not sure how useful any description I give is going to be
What I'll probably do instead is dig out a few of my other IEM's this weekend and compare them with the IX to hopefully give anyone who's interested a better idea of what to expect if they do decide to splash out on a Piano Forte VIII-XI
