I have to respectfully disagree on this. A lot of pro audio gear (both electronics and headphones) are quite popular among audiophiles. Just look at Lake People, Benchmark and Beyerdynamic for example. The DT 1770 and 1990 pro are both perhaps even more popular among audiophiles than the Amiron. Not everyone enjoys the usually more mellow consumer tuning plus pro audio gear is often better value for money as well (lower margins vs. consumer gear).
Also speaking as someone who is very likely to buy the Clears (not sure yet which variant), there are some obvious ergonomics issues for my head shape/size in the Focal high end lineup. My take: brilliant sound, but they have a lot to learn from Sennheiser in particular when it comes to ergonomics design.
A weight of 450 grams for a dynamic headphone to me is downright questionable. Focal cables are quite heavy too. I don't use headphones for 30 minutes or an hour at a time only when listening to music, they are something I always keep on when I'm on my computer. They have to be good for 6+ hours in a row. I'm simply not convinced the materials chosen here are optimal (look nice, but I'd take lighter high quality plastics instead any day of the week). The headband design also goes against what most other manufacturers are doing (taking pressure away from the top as that's the most likely hotspot). Even from the three auditions I've done with the Clears so far it's very obvious to me that the HD 800 S I have at home is in a completely different league when it comes to ergonomics. Then there's also the light grey color vs. black issue - it may not have the initial wow effect, but the professional version is likely to look the same for a longer time.
If the Clear Professional has a somewhat different tuning and more clamp, it could be a significant ergonomics upgrade for many people. As for the sound, we'll have to wait and see. There's no way I'd buy the Clear right now if I had any ergonomics concerns or was at least a little curious about the pro audio tuning. At 1500$ it's a big investment intended to last 5+ years, what's a few more weeks or months of waiting when you can then be completely sure you made the right call for your taste?
