I bought these on 2/28/12 from Matt at SpringTree and they're still in brand new condition (10/10). I've put a few hours of head time on them, but other than that, they've stayed in their case and away from anything that might degrade them.
At this time, since I've been away from Head-Fi lately (school), I am not sure what my asking price is yet. But throw me an offer and we can deal. I have a lot of feedback, so buy with confidence. Thanks!
