Hey guys, I currently have a sony v6 with fiio e17. I'm looking to purchase a new closed headphones with a budget of $300 ~ $400. Please bear with me, as I think my taste in music is quite different. I'll try my best to describe, but it won't hurt if you can just google a bit hehe. I usually listen to touhou and vocaloid (covers too) songs, which I think it would fit somewhere in the electronica area. I also listen to some jpop and kpop (Supercell, YUI, SNSD, T-ARA, etc). I've set my eyes on the AKG k550, but I wanted a detachable cable preferably. Can anyone provide me some suggestions?
