Very similar to the EX1000, though I'd think those are ultimately even better phones than the 7550 (despite their more problematic treble). Anyway, both IEMs bear an uncanny resemblence, the 7550 being just a bit more mid-centric and laid-back in treble. Listening to the 7550 and H3 side by side, the former sound simply cleaner with more coherent tonality, whereas the latter impress with excellent mids/highs separation on the one hand, but disappoint with bloated and somewhat diffuse bass on the other.
Timbre-wise, the only edge the H3 seem to have over the 7550 are cymbals, 'cause their BAs exhibit more metallic shimmer, but pretty much all other instruments sound more natural on the 7550 to my ears. Putting on Mahler's 2nd (final movement), the 7550 win hands down over the H3 in my book. These are such great value for the money, particularly for classical listeners.
But besides classical, I've also listened to both with pop, rock, jazz and electronica and there were some tracks on which the H3 came close, but not a single one on which I ended up preferring the H3 over the 7550.
