When I reviewed the Urbanears Kransen a few weeks back, I came out with a fair review stating that the Kransen tends to favor playback material that contains heavier bass and mid-range elements. I mentioned that this particular pair is not for everyone. It is best suited for people who love music with a ton of oomph.
When I wore the Humlan, I kind of pre-conditioned myself to hearing something similar to the Kransen. Boy, was I surprised!
