There are few choices that I am considering.
Audeze iSine 20 (on iPhone),
and maybe Exmpire Ear Zeus Adel (this one is quite expensive).
From the reviews I read the sound signatures for those are quite different..
I used to own IE80, Shure 535, Westone 4(old version), Westone UM3x(old version), UE 900s, Shure 215.
UE900s is only good for price range $100-$200 (I got it for a little over $200). Sound...
