But how I know I will like the sound signature?
The only custom that you can tweak your sound signature is UE Personal Reference Monitor. But I'm not spending $2000
Unfortunately I haven't heard those.
I am no longer interested in sealed BA IEMS - too hard on my ears. But in terms of just sound quality, the portable IEMs that I like the most (in no particular order) are the ES5, Private 335 and IE800.
The IEM that I haven't heard but most want to is the K3003.
The IE800 is fine unamped although the sound is a bit thick. It's very nice for running around town.
