I am a mid-level basshead, especially sub-bass. How does it compare? For reference, my home headphones are Denon D5000's and I listen to a lot of indie rock and electronic music like Of Montreal and Orbital.
Compared to the Denon D7000 which I once owned, the ES10 is a pretty far cry in terms of bass quality. I don't recall it being able to reproduce the sub bass well also.
Ath isn't really known for making headphones that satisfies basshead. The closest can so far that could satisfy your preference from the ath lineup could be the pro700mkii.
If not, the UE9000, Sennheiser Amperior or other cans designed for your preferred genres might be better.
