Was just meandering my typical anime and game blogs and stumbled across this http://mamitan.goodsmile.info/2014/02/toon-workshop-headphones/
Apparently it's a collaboration with fostex and a company called goodsmile that does anime related collectible things.
Main website is here http://www.toon-workshop.com/
But curious for those who've used Fostex headphones, how are they at isolating outside noise? Also is the sound quality balanced out? My fear is that these may be aimed at a younger generation and may be heavy on the bass side. but only time will tell.
