This sucks. I guess with such a crowded market, they had a hard time selling enough mid-fi units to the mobile masses, and their higher-end units just don't generate enough sales to keep the company viable. I'm not a headphone hobbyist, I wouldn't even call myself much of an audiophile, but I use my HD600 all the time for listening and for musician stuff. It strikes the perfect balance between comfort, good neutral sound, and low enough cost that I don't worry about babying it to keep its resale value in my chaotic studio. I hope they keep making them.
