On the go: Simgot en700 pro, FAD heaven II, and sometimes my old Sony MH1C.
Used to own:
Shure SRH-440 (with 840 pads), crescendo ds11 (basically an ACS T15) with custom tips, plus loads of cheaper headphones and in-ears. Chiefly the Philips SHP8500, AKG K350, Sennheiser CX-300mkII and xEars XPA 2 Pro.
Sony Walkman A15 Hi-Res DAP
HiFiMeDIY sabre 2 DAC with USB isolator
A lot of post-rock, indie rock and "regular" rock, but also quite a bit of minimalistic piano music, classical music, pop, various sorts of metal, Drum 'n Bass, techno, grunge, folk, sometimes rap, ambient, and, and... Let's just say that putting my entire music library on shuffle is a contrast rich and very... interesting experience.
