hi ClieOS...need help on this..i have to choose between these iem

- jbl reference 220
- jvc marshmallow fx33
- creative ep-360
- soundmagic pl-11
- soundmagic pl-20

if neglect the price n accessories factor which one is better??i need an iem that has a good bass with enough airiness and spaciness (good soundtstage)

currently only owns sony hmp-70 and a cheap 'china sony' iem...so i want to ugrade abit (but still on low budget)..
