Hi there,
I'm in the market for portable closed headphones, and have narrowed my shortlist to the above two.
Does anyone know how these two compare?

I compared both at shop, and Beyerdynamics in my view had better treble, the another pair was a bit darker, but they say that Beyer itself is dark enough.
