OK audio guru's, need some advice. Looking for a new set of IEM's or in-ear 'phones. Budget of around £100. Can probably go to £100 for a replacement amp as well if the Fuji is going to be an issue, but only if really needed. These are to be used daily for the walk to work, all sorts of music from punk, metal, Scottish folk, dance and audio books --- don't ask, I have weird tastes Not a fan of full size/hipster headphones, bleargh!!! Currently running Sony MDR-EX300, powered by a Sansa Clip+ and a Fiio Fujiyama. So, recommend away and ta in advance.
