As far as I know, they don't. Based on my research, reading around about the CAL!s, it's a variation of the long-stopped Denon AH-D1001. I don't know how that will be useful though. :P
As for how much I pay for it, it's 2576 rubles, around $83 US. Picked it up at a physical store of an online shopping site, because I don't want to wait for them to send it to me. :)
Update on the CAL!: the cans are pressing, albeit very, very lightly, on the cartilage. My ears does fit in the cushion, but I think it's a bit shallow. I didn't notice it doing this first, but after a couple of hours I felt the pain. Any idea how to alleviate this?
