You can get them in the states on Amazon.com, but price isn't going to be too much different than ordering from Japan (and paying for shipping). I have them on now. I usually listen to IEMs at home and on the road, but now these have become my preference for at-home listening. I should have about 60 hours on them. As for the mids, the the mids were never a problem. Just with more burn in the whole sound becomes more focused and detailed. It's like getting your HD antenna set at the right angle for the best reception. The whole sound spectrum is just so right. I haven't heard them, but I don't think those who own the S600, S700 or D800 really have clue how great these sound. Amazing.
