I've never used IE type headphones.
I'm using Aurvana Air, AKG K540, K450, Senn HD238(internal sponge removed) and satisfied with their sound.
Since using OE type headphones will sweat me a lot in summer, and Air cannot block so much noise,
I'm looking for some IE type headphones.
I saw the review on Aurvana in ear 2 and this seems to be good.
Also I'm interested on panasonic products, and HJE900 seem to be very attractive.
HJE900 has merits since its cable is changable, but I cannot find much reviews on HJE900.
I have listened to HJE700. It was good but bass was slightly muddy for me(not more than K450 though).
Price ratio in my country is about Aurvana IE2 1:HJE700 1:HJE900 1.5
It'll be great help if i can find reviews on HJE products.
Or your personal recommendation will help me a lot.
