Headphoneus Supremus
Eikon may well have lowered mid-bass & elevated sub-bass vs Atticus. But in absolute terms (comparing it all headphones, speakers, whatever else) it sound rather flat & powerful to me in the entire bass range. That's just tonality...you also should take slam/impact into account. My padauk Eikon is a pile-driver in the bass. It slams evenly all the way down. And then there's timbral accuracy: all that good bass sounds real/realistic. A string bass sounds just like itself (ie, wooden body, reverberant) vs an electric bass, which sounds fat & electric. That's on trance, studio pop, blues, other electric/electronic genres.
But the beauty of the Eikon is when I switch to moderate volume classical, choral, opera, polyphony--it becomes a totally different headphone, very well scaled to acoustic music. Now, instead of bass slam, you pay more attention to that big, spacious soundstage + all the details in the mids. The Eikon is a very resolving headphone (another factor to take into account).
