Just got these. I'll be adding to this post as I burn them in with impressions, comparisons, and a review. And cake. Some impressions; the shells are big. And they're shallow-fitting earphones so they tend to protrude more than you would think. Makes them slightly susceptible to wind noise while biking, and not good candidates for sleeping use. Isolation is average. Comfort is good. The cable is very nice. Supple, flexible, and not prone to tangling. There's also this little... I don't know what you call it, but there's this piece that essentially serves to adjoin to the left and right channels for storage purposes. Works really well, but it's too high up to be use while wearing the Hibiki, unless you just have a reeeaally skinny neck. Edit - That little piece can in fact be moved up and down the cable! As far as sound goes I'd say they're moderately L-shaped. Compared to the KZ ZST, they have much better vocal timbre, and carry more weight throughout. Obviously there's a pretty big price difference between the two but they share a similar design and lots of people have the ZST. I've got the BGVP DM5 and KZ ZS6 incoming, for stuff that's more similarly priced. And I have the Carbo Tenore which I think will make for an interesting comparison.
