So I just got my ES10s today, a complement to my ESW9s, but more for rock.
Wow, that was no joke about the deep and punchy bass. It just kicks my ears coming out of my tube amp. Mids are definitely more recessed compared to my woodies, but it's still very liquid smooth. Highs are definitely rolled off; good detail but definitely restricted and without much sizzle--hopefully they'll open up with a few hundred hours of burn in. Soundstage and imaging sound similar to the ESW9, good but not blow-your-mind good.
The build is solid--it feels much sturdier than the ESW9 and it's much more comfortable out of the box (headband tension is less), but I wish the pads were leather (these will disintegrate over time like the original pads on my W100s). Anyone know of leather pads that fit?
