Got a pair in today. Ordered from ALO. Boy do the Japanese know how to manufacture stuff. The build is just ridiculously solid feeling in hand. They isolate like crazy. I read that the cable is quite microphonic, but I don't find it to be too troublesome so far.
Sonically, first impressions-
Like others have said, transparency, and detail. But I think the area they're clearest in of all is the midrange. I mean I've never heard mids like this. And that part doesn't sound falsely pronounced or artificial in any way. Just the best midrange I've heard to date. I do wish they had a little more heft to the lows, but I guess you can never have it all. Running them out of my work mac, with Headstage USB DAC cable to Objective2 amp, I find the treble to be borderline biting and harsh. But playing straight out of my more mellow Sony X1060 things calm down just right. It's cool to see how much they respond to equipment pairing. For tips I'm having the best results with Sony Hybrids.
Pretty interesting pair of earphones. I'll keep playing around with different combinations.
