Mine have been pretty much perfect since I got them in Feb 2014.Mine felt perfect, unless I grinned really big, then the right ear would lose its seal.
Recently, I did an outdoor gig (East TX) on a nice humid evening.. and when I stepped up to sing, my right ear lost it's seal. It's definitely a "heat/sweat" thing, not a common problem, and not a build flaw.
I have no intentions of any re-molds or returns, as one or two gigs a year with this potential issue are not worth worrying about IMHO.
YMMV.
