Hi there, I've been searching around for an advice on upgrading from Image S4 and all the roads seems to lead head-fi. I've read couple threads of similar topic, but people that were asking this question seemed to had more money to burn than me, hope it is not too big of problem for me to asking it again. I was quite satisfied owner of Image S4, until recently when a cable gave up, leaving me fondling with it trying to get at least one of the ears working. My primary genres of interest are Electronic music, mostly Dubstep, DnB, IDM. Budget is up to $150, with ipod use in mind. I really liked the bass in Image S4, and was wondering if there is an option with decent step up in sound quality. So far my bit of research and limited knowledge presented me with following options: Audio-Techinca ATH CKS70 SB JVC-Victor FX500 Head-Direct RE0 Future Sonic 010-045 Atrio M5 Ultimate Ears SuperFi 5 EB Am I missing any options? Which one would you recommend? Thank you!
