The HE 400 is the best can in the this group; has a colored mid-range, but I would not say that it is in your face. The other two have a "V' shaped EQ of different size and depth with recessed mids and could be described, at least by some, as "in your face." For slam I prefer the Grado SR line and some of the Ultrasones.
The HE-400 colored mid-range... there seems to be quite a lot of complaints about recessed mids, I understand what 'not in your face' could mean, is it noticeable or only on specific amps/looking for where instruments sound recessed?
can you help shed light on it I havent had any headphones to compare differences with at least not in the same competing fidelity range.
edit: clarified headphone
