Appearantly yes. Honestly, I wouldn't pay extra for limited edition or other funcy things as long as they don't improve SQ. But some people like it and I do understand it, if you like it too, go for it really both are wonderful cans. My only point is, they are more or less the same stuff, you can always get an aftermarket cable for these world known most seller headphones. Construction is pretty much same except the cups and people say amperior has a big advantage cuz of the cups. I would only get 1 of them actually. Nevertheless if you like it and also thinking about collections too, go for them I would say. If I had money to spare I would like to have them both too
I suppose "need" doesn't come into it. More a want.
