Just bought the R70x on Amazon for $299, gotta have detachable cables, which these don't, otherwise would snag a pair. Only Audio-Technica cans I've owned before were the M50x, which was sold after 6 months.
FrogmeatI got rid of M50x after a week. Mediocre and severely overhyped throughout the internet. ATH-M70X was keeper, but it was simply too much like my Pioneer HRM7, just with less isolation and less comfort (not that I find M70X uncomfortable at all, it really isn't for me), so I sold it off as well.
