Am I the only one who is not a fan of their design? I get that there might be a slight reference to the legendary Koss SP-3 from 1958, but come on - they don't have to look THAT antique.
I think they look a bit too sterile for something that people "wear". Very corporate, not very soulful. Especially the big blank aluminum surface. The head band also looks rather plasticky.
The british stuff, eg from B&W, has more elegance. Combine with nordic minimalism and maybe some natural materials like leather and it would be more appealing. But I'm sure they are technically superior.
