Indeed they haven't. I LOVE...repeat...LOVE the FA-003's and to a slightly lesser degree, the FA-002. When it comes to full size cans, both the FA-003 and FA--002 are always within arms reach. They are awesome for double checking critical mastering files. They are awesome for simple music enjoyment as well. During the time that has elapsed, only one other full size headphone has impressed as much but the review is pending on that one.
