It´s really odd to see them sold only on the pro audio site - to my best knowledge they were originally supposed to be a consumer product going against Westone and Shure. Even the sound signature is mainstream music friendly plus the build quality won´t be able to take pro-audio stage use very well at least if the current version is even remotely close to the initial one. It´s a shame really, I really think the driver tuning is one of the best in the industry. It´s just the build quality that let it down (and the vent design that eventually always clogs and is almost impossible to clean).
Hopefully there will be an updated version someday. My wishlist: strong one part acrylic or mag/alu shell, new cable connector (the plastic one was so flimsy) and slightly more upfront mids and you have one of the best all-rounders in the industry and a future classic.
