Hi. My sony mdr zx600 headphones are bothering my skull after long hours. Obviously at this price i can't find "perfect" headphones but i just need something that has good sound as well as being very comfortable. Full sized earcups that don't squish my head, closed back, solidly built and has sort of a flat frequency response?.. I listen to a wide range of music and i'd like something that'd sound decent enough for everything. Thanks. look at the HD428 and shure srh440 at the moment.
